[GUIDE][TOOL][v1.2]-=Solved=-The Google Splash Sceen & Bootloader Graphics - Android Software/Hacking General [Developers Only]

Attempting to modify your bootloader may brick your device!!
Updated to v1.2: August 23rd, 2014
-Embedded a solid jpeg extractor in rlimager1.2.c (java is no longer needed)
-Added a zero byte function to fix the encoding of rgb0, bgr0, 0bgr, & 0rgb pixel formats​A while back I wanted to make a boot animation for my Nexus 7 2013, that utilized the Google splash screen in the first part of the bootanimation. I started searching Google and XDA, and found that it was embedded in the bootloader somewhere, but nobody had a clue how to retrieve it. I could see the battery charging icons with a hex editor and use FFmpeg to convert them from their encoded rgb24 pixel format into usable images. That was easy, but I couldn't find what I was looking for. I then figured they were in some odd pixel format, maybe even proprietary. I made loops going through every conceivable pixel format at different widths, generating 1000's of images, still nothing. The last thing I tried was making an image where every bit in the bootloader was translated into a pixel, either on or off, still nothing. I pretty much gave up, until I came across this thread. I had heard of run length encoding, but didn't know it was used in Android. I soon found that Google and some manufacturers were using it for the graphics in their bootloaders.
Hit the button below to see the splash screen for the Nexus 7 2013, this is a pixel for pixel exact image, with the Google logo and Unlock Icon in their un-encoded form as seen on the devices screen. (unfortunately the splash screen wasn't encoded as a complete image, the text was encoded one place and the lock icon in another, so I did have to use photoshop to make a 1200x1920 black background and place the Google logo and the lock icon in the right position.)

The complete Google splash screen in full 1200x1920 can be downloaded as an attachment at the bottom of this post. It is a PSD with a black background layer and the 518 pixel "Google" and the 72 pixel "unlock" all on separate layers.
The "Tool":
This is a Windows batch script I wrote to find images in any type of file. Included in the zip at the bottom of this post is: a modified run length encoder/decoder, rlimager1.2.c, that does the encoding/decoding and the extraction of jpegs from any type of file.
Rlimager1.2.c is based off of the original to565.c put out by the AOSP several years ago. To565 was made to convert an rgb24 image into a rgb565 run length encoded file which could then be named initlogo.rle, and packed into the boot image for a kernel splash screen. Of course having the ability to encode images in this format left users the want to decode them as well (to make sure it worked before they flashed it to their device). XDA user @zebarbu in this thread, made a program to decode rgb565 rle as well. I must credit both of these authors, as rlimager1.2.c is based off of both these programs.:good: I have added additional decoding/encoding of some newer formats; as mentioned below; as well as a jpeg extractor and a function to write 0's where ffmpeg will put 1's in the case of certain pixel formats.
The executable rlimager1.2.exe was compiled with mingw32-gcc 4.8.1 on a 64-bit Intel running Windows 7, and has been tested on Windows 7 Home Premium and Windows 8. The batch script, RUN_length_imager_v1.2.bat, will not work with obsolete versions of Windows. The source file for rlimager1.2.exe and RUN_length_imager_v1.2 batch script are available in the second post, as well as in the `src\` folder of the download. FFmpeg is also in the download, and the source can be found here, while the included pre-compiled version was downloaded at Zeranoe.
Googles ADB is also included in the download, which is located at the bottom of this post.
"Run_length_imager_v1.2.zip", should be unzipped into a new directory.
Click the button below for instructions on how to use rlimager1.2 by itself. Rlimager1.2 is a standalone command line program.
Usage:
rlimager1.2.exe ([-e] [2-4] | [-d] [2-4] [-m] [max run] [-o] [offset]) < input_file > output_file
Mandatory, one or the other
-d (2-4)Run Length Decode input_file from 2, 3, or 4 byte color pattern
-e (2-4) Run Length Encode input_file to 2, 3, or 4 byte color pattern
-j (output root name) Extract Jpegs from file. Output name can include a full path.
-z (skip) -o (offset) Zero every (skip) bytes, starting with (offset)
Optional for [-d] decoding only:
-m (max run) Maximum pixel run to decode. Default is 0, which defaults to the maximum allowable for each color pattern
-o (offset) Offset (in bytes) to start decoding. Default is 0
Examples:
rlimager1.2 -d 4 -m 8064 < "C:\example_file.rle" > "C:\output\rle_decoded\example_file.rgb0"
rlimager1.2 -j root_name < "C:\users\downloads\system.img"
Notice with the jpeg extractor example above you have to use: < "inputfile"
rlimager1.2 -z 8 -o 5 -i "C:\output\example_file.rle" -e 4 < "C:\example_file.rgb0" > "C:\output\example_file.rle"
The above example run length encodes the input file, then takes the output file and zeros every eighth byte starting at 5
You can also zero byte any file without doing it all on one line, like:
rlimager1.2 -z 5 -o 8 -i "C:\file_to_be_zeroed_every_5th_byte_strarting_with_the_8th.raw"​
To load a file into RUN_length_imager_v1.2.bat, you have two options:
-Drag and drop the file you wish to use onto the "RUN_length_imager_v1.2.bat" file.
-Run the program and choose option 4 at the menu. This will pull whichever partition you choose, from your device to your computer.
Note:
The second method requires you to have your ADB drivers for your device installed on your computer. You must also have busybox installed on your device. If for some reason ADB will not start and you end up with a blank partition list, simply close the program and open it back up and it should work. If it still doesn't work your ADB is probably not functioning correctly.​
First and foremost before you get too much into searching for run length encoded images, you should check for jpegs first, especially if you have a Samsung device. It is really fast, and all you have to do is drag the file onto the RUN_length_imager_v1.2.bat file and select option 8 at the main menu. In five seconds or less, if there are jpegs in the file, you will have all of them in their entirety.
What is run length encoding?
RLE is a method of encoding an image with the intentions of having a smaller filesize. If you have 1000 pixels of the exact same color, you can save memory, by instead of encoding (R,G,B) 1000 times; you can add a count before the pixel description, 1000 (R,G,B). This works real efficiently for images that have lots of pixel runs, but an image where every pixel is different actually will take more memory than your conventional method of storage.
The Run Length Patterns:
I have found three different run length patterns so far. The first is the original one mentioned up above, rgb565, or as I call it 2 byte. This format can be used to encode any pixel format that uses two bytes per pixel. It works like this, the first 2 bytes is the count and the next 2 bytes is the color. The M8 uses this encoding for its bootloader graphics.
Note:
When I say "can be used to encode any pixel format that uses two bytes per pixel", I really mean pixel formats with sequential pixels. Some pixel formats use the YUV colorspace. Not all formats stored in the YUV colorspace store the pixels sequentially. For instance some YUV pixel formats will take 6 bytes of data for 4 pixels, but the first 3 bytes are not just for the first 2 pixels.
In the RGB colorspace there are BAYER pixel formats which don't encode sequential pixels either, the colors are split onto different lines in this method. Neither of the previous examples are candidates for this type of run length encoding.​
The Nexus 5 and 4 use this next one, what I call 3 byte, because it can be used to encode any pixel format that uses...3 bytes per pixel. This encoding uses a 1 byte count and 3 byte color. This is easily the slowest method, for obvious reasons.
The last one, up to this point, is what I will reference as 4 byte. It works with four byte per pixel pixel formats, and uses 4 bytes for the count and 4 bytes for color. Both Nexus 7's use this format.
There may be more patterns, but it is hard to find partition dumps to download off the internet. I have found several though, and found run length encoded images in almost all of them. If anyone wants to upload a bootloader, I will gratefully add it to my collection and see what is in it.
This program will take any file, and decode it using whatever pixel format you choose, and if you have run length decoding turned on it will automatically associate the proper run length method to make a usable image, if there is one. Another important thing when dealing with raw image files, besides the pixel format, is the line length (width). This width is encoded in regular image files like bmp, jpg, and pngs. But raw images are nothing but pixel data. To get the correct image, if there is one, you have to specify when to go to the next line. I have built loops into the windows script that will let you specify multiple pixel formats to run, with an embedded loop that goes through all of the different widths you choose.
You may want to load a whole bootloader file to see if there are any images in it. To do so just drag and drop the file onto "RUN_length_imager.bat" Since the file contains different types of code and possibly images, you will want to set the maximum pixel count down to around 1000. This will limit the maximum number of a pixel run. This is necessary because not all of the data going through the decoder is meant to be run length decoded obviously, so FF FF FF FF 01 01 0A F0 in a 4 byte rle scheme will decode to over 16 gigabytes if you don't have your maximum pixel run set down to halt this.
Note:
You can stop the program at any time. I designed the program to save your settings before running and after changing anything. So if you accidentally don't set your max run and it seems like it is taking forever, and you are watching the output file size growing and growing, you can simply x out of it, or close it. Restart it and adjust whatever you have to.​Another variable is the byte offset. Since the very first count byte has to go into the decoder as the very first count byte, you may have to offset the whole file up to a certain number of bytes as specified below.
For 4 byte rle patterns offsets to be tried are 0,1,2,3,4,5,6,7.
For 3 byte rle patterns offsets to be tried are 0,1,2,3
For 2 byte rle patterns offsets to be tried are 0,1,2,3​
The last variable is the width. Hitting 2 in the program will allow you to set a range, or specific widths. Example: My Nexus 7 2013 bootloader has the Google logo as a 518 pixel wide image, the android as 712, the buttons as 1090, and some other things at 600 and 960. I would enter:
Code:
518 712 1090 600 960
You simply separate the different widths with spaces. You can't mess up, you can put whatever width (in any order) you want to in and it will make an image.
The second method is an exploratory method, where you enter the starting width, skips, ending width. All separated by commas.
Example:
Code:
712, 1, 1200
This will run through every width, incrementing by 1, from 712 pixels to 1200 pixels.
Note:
The height is automatically calculated based on the width, filesize, bytes per pixel. This happens at the core of the loops.​Click the button below to see what the entire Nexus 5 bootloader screen looks like when the bootloader "file" is loaded with these settings used: pixel format rgb24, max run 1080, offset 0, line length 1080. The image is really big, because the whole file is run length decoded.
After you click the button, scroll down and you will see the bootloader screen towards the bottom of the image.
This is the Nexus 4, whole bootloader, pixel format rgb24, max run 1080, offset 0, line length 720
After you click the button, scroll down and you will see the bootloader screen towards the bottom of the image.
You've Identified there are images, but how do you extract just the images?
You need a good hex editor, don't worry though because you don't have to look at any hex. I prefer 010 Editor by SweetScape Software. You get a free 30 day trial. Download it. Load your bootloader file into it by right clicking on the file and selecting "010 editor". If you don't have your bootloader file you can use option 4 in RUN_length_imager.bat and pull the partition from your device. If you don't know what partition you are looking for or how to do it manually, here is an excellent guide. If you use my script, the partition will be saved in the "__partitions__" folder.
Go up to View:
Set Left Area to Char
Set Right Area to Binary
Change Line Width to Custom Width
Choose a value where the characters on your left pane almost fill up your screen so that when you start scrolling over, your right pane (binary) is right there. The right binary pane is a lot wider, that's why I prefer it on the right. Also choose a width that is evenly divisible by 8, I set mine at 224, using a small 1366x768 laptop.​
A real handy shortcut in 010 editor is Ctrl + and Ctrl - to enlarge or shrink the font.​The 4 byte run length encoding is the easiest to identify because there is 4 bytes for the count, and the biggest number you can store into a 4 byte address is over 4 billion. The 3rd and 4th bytes are usually nothing but zeros. The only 4 byte pixel format I've seen used so far is, bgr0, which also has the fourth byte as nothing but 8 zeros. Here is what a typical looking 4 byte rle image looks like.
Notice how the count value, mostly, show up as just four periods ....
Sometimes the first byte (period) will be a different character representing a higher value for a run of same colored pixels. Also notice that there is a lot of black and white (gray) shades in the color values. All colors on a grey scale, represented in rgb, are equal values. A value of 255,255,255 is white 200,200,200 is a light shade of grey, and 0,0,0 is black. The rgb values will always be identical to be an exact shade of grey. This image is part of the Google logo which is mostly black and white.
Any area that you highlight in the "char" pane will also be highlighted in the "binary" pane when you scroll over, you'll find this extremely handy. These 8 bytes is one complete encoded run, which represents 15 pixels pure white. You can see exactly how the four count bytes sit beside the bgr0 color bytes. Byte 1 is 00001111, binarys equivalent to decimal 15. Bytes 2, 3, and 4 are 0; then the color bytes 5, 6, 7, 8. Blue is represented with the 5th byte, green the 6th, red the 7th, and the 8th byte is not used in this pixel format. Don't get confused about the pixel format, because this method of encoding will cover all 4 byte per pixel formats, some could use the 4th color byte (or alpha), and the order they're in is not that important right now. Unless you know exactly what you are looking for, like the infamous green android laying on its back, you may be trying to pay more attention to the green column when trying to find where the image starts or stops.
(This is the binary copy of the android image you see if you have a Nexus 7 2013)
(from Nexus 7 2013 bootloader)
This part can be kind of tricky, I actually surprised myself at how good I was at "getting lucky" and finding the correct beginning and ending of an image in the bootloader files. So that probably means that it really isn't that hard, it is just not something you encounter every day. Being aware of how your image should be encoded helps a lot. If you know there are 100's of black pixels at the start and/or end of an image, keep that in your mind when looking at the characters.
An image will never start or end with the count byte(s) as 00000000!!! But, often times they DO start or end after some zeros, or before some zeros at the end. Take for example: This is the beginning of one of the lock images. (notice how it is right after the text ANDROID BOOT, hmm)
(Keep in mind that this is a 4 byte pattern run length encoding, which actually will consume 8 bytes total per run. Four bytes for the count and four bytes for the color. The other two patterns look as you would think: 3 byte .### 2 byte ..##)
Notice how the count bytes before what I have highlighted in blue is all zeros. So you won't start there, move right and see what that is. And that is your image start, it is a run of 28 solid black pixels (0,0,0,0) Once you have identified the start, and hopefully selected it as I have in the screenshot, write down the number after "Start:" Which is 3097596.
This is the end of the lock. Notice the characters all of the sudden changing, this is an indication of a color change. I visually scanned line by line and found this spot that separated all the ÿÿÿ and ÀÀÀ's up above to the newer assortment of characters like ## and 33Ì
Now you need to isolate just that image. With those last 8 bytes selected, go up to Edit - Select Range, and down at the bottom of the screen, enter in the start byte you wrote down earlier. Hit enter and the encoded image will be selected. Copy this by hitting Ctrl-C or going up to Edit - Copy.
Go to File - New - New Hex File
Hit Ctrl-V to paste, or go to Edit - Paste
Now save that file somewhere, and drag and drop it onto "RUN_length_imager.bat"
I already knew the width of the image before writing this, but here is the output with the Line length set at 60,1,80 and pixel format bgr0
Notes:
You can also encode jpg, bmp, and png files into whatever 2, 3 or 4 byte pixel format you choose. The run length encoding will be automatically adjusted according to which pixel format you choose. When encoding images into the pixel format rgb0, bgr0, 0rgb ...
Any of those 4 byte formats. FFmpeg will put 11111111 in place of the zero in the zero byte position. I'm not sure why it doesn't put 00000000 like it should, but I know how to fix it, but it involves another option, and I haven't gotten to it yet. If you were to try writing this to your device, I have no idea how Android would treat this 11111111 in the null spot, because as far as I know rgb0 (and cousins) is a made up definition by the writers of FFmpeg to describe rgb24 as rgb32 with 8 bits per color, and 8 padding bits.
Nexus 5 & 4 use the pixel format rgb24. The whole bootloader screen is encoded in one pass, as opposed to drawing several images at different spots on the screen.
The Nexus 7 1 & 2 use the pixel format bgr0. It's kind of ironic that at first when I was looking for the Google logo, I thought it was entirely made up of black and white pixels and stored in an 1 = white 0 = black, binary format (that would account for no one being able to find it, unless you do like I did and use the monow or monob pixel format in FFmpeg), but in actuality the format that it is stored in can potentially contain billions of colors. (4 byte color)
The Nexus 7 2013 Unlock Icon has an extra white pixel at the bottom right that you can clearly see on the device, now that I told you it's there. Does it mean something, or is it just poor editing by the people at Google?
The Nexus 7 2013 has the Google logo encoded in 3 different places in the Bootloader. They are binary copies of each other, so that leads me to believe that the reason for this is to discourage people from trying to edit the images. Maybe you'd brick if you just changed one and not all three? I don't know, but can't think of any other reason why they would do this. There is also two unlock icons, not counting the big one on the bootloader screen that asks you if you're sure you want to unlock it.
The Nexus 7 2013 has the only bootloader, that I've encountered, that not only stores images in a 4 byte run length manner, but there are also non-encoded 3 byte rgb24 images for the battery icon, and charging icons. Even the older Nexus 7 has all of the images run length encoded.
Samsung bootloaders use jpegs, although I did find the Linux penguin, non-encoded in the Note 3. I also found the "font mask" that uses bits to make some different fonts stored as bit masks. You can see it, using the monow or monob pixel format and setting your width at 16 32.
The HTC M8 uses the pixel format rgb565. The only device I own is the second generation Nexus 7, and it is the only one where I have been through the bootloader with a purpose. Since I don't own a M8 I really kind of just glanced at it in the hex editor and found the exclamation triangle, the htc silver logo, and the android laying on its back; all run length encoded. It also has the bit mask font embedded in it for the text, as I mentioned about the Note 3.​I take no responsibility to any damage that is done to your device or computer with this program.

echo.the right spot, and the count will be read as color data instead of count data, resulting

& Based off of the original to565.c program to convert raw rgb888 r=8 g=8 b=8 images
& to, 2 byte count, 2 byte color run length encoded rgb565 r=5 g=6 b=5 files.
& Mainly, if not always to my knowledge, used for creating initlogo.rle files for kernel splash
& screens.
&
& Added decoding of 2, 3, and 4 byte rgb(x) patterns
& Added encoding of 3 and 4 byte rgb(x) patterns
& Added byte offsets and maximum pixel runs for decoding files not totally
& encoded in a run length manner
& Version 1.2 added:
& Jpeg extractor, to pull jpegs from any file or drive/device image
& A zero byte writer, to undo what ffmpeg does to rgb0, 0rgb, bgr0, and 0bgr pixel formats

Very nice work! This is actually more interesting than it seem. It's also a way to inspect binary code in unknown blobs. Another thing to notice is that you can probably automate the correct image size, for images that you know contain vertical lines. If you look at the padlock image sequence, you see that the images contain parts that are "sloping" either upward or downward, this can be used to look for the correct direction to increment/decrement the size counter.
So if you remember your basic math for the slope of a line:
m = Δy/Δx = (y2 - y1)/(x2 - x1)
you can plug some pixel values in and get the slope, and subsequently the direction for the counter.
Obviously the most difficult part will be to detect what is a "line" when there are other pixels there.

Thank you, you can imagine my excitement the first time I had the logo I was looking for come across my screen
I was trying to think of a way to automatically choose "the right image", but cognitive dissonance kicked in and I figured that people would rather see lots of images. Kind of kidding, but I wanted it to work for almost all images, and my expectations kept leading me back to nothing.
Here is something, i forgot to mention, I found this is in the n72013 4.02 bootloader that I don't ever remember seeing on the device. It is the ASUS logo, with their slogan underneath it. But it is not all there, I've checked and checked and this is how it is in the hex editor too. It is located at the very bottom, right about the last Google logo, width is 600.

^^ And as you see above, the sloping lines is probably the remainder of the "missing" pieces. For some reason the image has been split and pieces moved around, just like for any other file. This is probably because you have extracted this as a blob from memory or EMMC in which case these pieces may have been shuffled around by internal MMC wear leveling. But the way these pieces are linked together should be via inodes and you'll need some better tools to read these. (It should be some kind of address immediately following an incomplete image.) Another possibility could be that the screen driver FW like to read images in pieces...

I was thinking that this data was from the factory download, but I just checked and you are indeed right. It is not in the bootloader.img from google, but only on my mmcblk0p12. As for the white lines surrounding it, the bottom lines are the Google logo (at 518 pixels) and the upper white areas are the up/down arrows and the second unlock icon. Your point was still well received! And thanks for your insight:good:
Here is the same image (I cropped out the upper irrelevant stuff, but the same data) at 518 width.

If you haven't read it yet, try a search for ARM_ELF.pdf
If the partition you're reading (like a boot.img) is an ELF file it will give you the offsets for the start of files (that's how I found my systems initial splash image) and the byte size for that file and any other files in that partition ie. Boot code, splash screen, text data.
Throw a boot.img/recovery.img into a hex editor (I use HxD) and alter the displayed byte count from standard 8/16/32 etc to 320 (or your screens pixel width) and scroll through and you'll see the data layout roughly of your splash screen (really basic way to find it)

If only it would of been that easy...
But, if you are dealing with a non-rle images, you absolutely can see it's "likeness" in a hex editor with your width set correctly. An image that is run length encoded bears no resemblance to anything, except some of them do look like random waves, but that's another story.
Those images were the first things I noticed in my N7 bootloader, not what I wanted though. But since the non-rle images were in a rgb24 pixel format, with 3 bytes per pixel, my battery charging icon that is 340 pixels wide could only be seen correctly (in a hex editor) at 340*3=1020 for the width. That's one of the things I like about 010 editor, I think Hxd will only go up to 512 for the width, 010 editor goes up to 1024.

Ah yes, I'd forgotten about .rle :banghead: can't see it but can find it.
You will find the address of them in the ELF data, especially the splash and battery charge on power up, it's in (I think, off top of my head) hboot, if you know the partitions offsets from 0x00000000 (or you have a full nand dump) there's pointers to them

You must be referring to the kernel, I am talking about the bootloader in the OP. There is no elf header/data in the bootloader, they are typically proprietary and written in machine code &| assembly language.

You've spiked my curiosity now, especially as I've not been able to work at my PC in a while
Is now off to see where it's pointed at from....

Here is the mmcblk0p12 from the Nexus 7 2013 and the whole bootloader.img from the factory download. I don't know if it would help you, I imagine you have a device to check, but I have the logo locations already if it would help you out any.
There are 4 locations of the image (the splashscreen isn't drawn all at once, it places the logo and the lock from different places in the bootloader) in the partition mmcblk0p12 they are all 43768 bytes long:
307760 o----c 351528
2390104 o----c 2433872
3075424 o----c 3119192
3166732 o----c 3210500​
In the factory image there are three locations, they are:
1183172 o----c 1226940
3265516 o----c 3309284
3950836 o----c 3994604​

The possibilities are endless when it comes to run length encoding. The three different methods that I've found probably aren't the only ones being used. Most people probably confuse rle with the old microsoft file format, but actually rle these days is a method of encoding. So, if you want to have 3 bytes for the count and 3 bytes for the color, you can do it. But if you notice, all three of the methods are 4 or 8 byte reads. No 3, 6, 10.... I wrote an arbitrary decoder for rlimager, but took it out because I don't see them ever using rle that doesn't add up to 4 or 8. Like 2 bytes count 3 bytes color, would be a more efficient way to encode 3 byte color, as opposed to 1 byte count 3 byte color (like they use). But it would be horribly slow. Here is the arbitrary decoder:
Code:
void arbitrary(int bytesofcount, int bytesofcolor)
{
unsigned int i, j, k, totalperpixel = bytesofcount+bytesofcolor;
unsigned long times, count, counttotal;
unsigned char color, instream[totalperpixel];
unsigned char colorbyte[bytesofcolor];
while(read(0,instream,totalperpixel)){
for (i = 0; i<bytesofcount; i++){
count = instream[i];
if (i > 0) {
counttotal = (count << 8) | counttotal;
} else {
counttotal = count;
}
}
for (j=0; j<bytesofcolor;j++){
color = instream[j+i];
colorbyte[j] = color;
}
for (times=0;times< counttotal;times++) {
for (k=0;k<bytesofcolor;k++){
write(1, &colorbyte[k], 1);
}
}
count=0;
}
}
But in the end, there are countless ways to run length encode an image. I've seen vertical encodings, diagonal, and horizontal. I've just simply found 3 used to encode images in some bootloaders...

Just flicked through a power point doc on image encoding including rle for tv transmission, it can be done with the bitmap fields as well!!
With any luck they'll keep it simple
Thought the LCD doc may come in handy as just for the screen being lcd, I don't think I've come across anything on screen images and encoding in Qualcomm docs so it's probably down to manufacturer how they do it (samsung and LG may use same as used on their TV's they make )

I think they'll keep it simple, as they have for this reason: The images that are run length encoded in android, usually so far, are meant to be decoded and displayed instantaneously. If you go to a more complex algorithm to encode images in a run length fashion it is only practical for storage! I went back and forth about whether to write this guide for weeks before ever releasing any of this information, because I feared they would change it up to something that would be almost impossible to figure out, barring a leak. Then I came to the realization that they are pressed for speed on boot, and I don't think they want to make it any more complex, and if they do, oh well the game is on again.
I think that is part of the reason that the nexus 5 and 4 which use the 1 byte count 3 byte color, encode the whole bootloader screen in one pass. Because that method of decoding is easily the slowest, so instead of decoding the android at specified location, then the text, then the buttons..... They just draw the whole screen. I really think they're trying to save as much time as possible when it comes to these decoding algorithms.

Not just that but more complexity would mean a decoder, screen drivers (possibly) memory space to decompress & read it from....probably more trouble than it's worth to go hi-tech just for (basically) a splash screen in general but definitely would be worth (in my eyes) having a GUI you could run it through and alter the bit fields (sad oldie stuck on windows and no time to really get into linux :what: ).

MediaPlayer.setDataSource(url) is not working in my app.
Im puttin the file "hello.mp3" in the assets-folder, and Im using the following
Code:
String soundUrl = "file:///android_asset/hello.mp3";
mp = new MediaPlayer();
try {
mp.setDataSource(soundUrl);
mp.prepare();
mp.start();
}
catch (IOException e) {}
catch (IllegalArgumentException e) {}
catch (IllegalStateException e) {}
This code works when I put the "hello.mp3" in the res/raw-folder:
Code:
mp = new MediaPlayer();
mp = MediaPlayer.create(getBaseContext(), R.raw.hello);
mp.start();
Problem with the last code is that I need to load the sound-files dynamically, and apparently you cant create a string or a uri with the correct sound-file at the end and insert that as the second parameter in the MP.create()-function.
Pseudocode - NOT WORKING
Code:
String mySound = "hello";
Uri myUri = "R.raw." + mySound;
...
mp = MediaPlayer.create(getBaseContext(), myUri);
Any ideas?

Amazing, several months later and still no one is able to realte how to play a local sound dynamically.

An issue with what you are trying to do is that there are multiple versions of MediaPlayer.create() and MediaPlayer.setDataSource() which take different types of parameters.
R.raw.hello is NOT a string. It is an int. Look in the gen directory to find the generated file R.java and in this file you will find raw which has a public static final int definition for R.raw.hello
R.raw.hello has to be passed to one of the routines which takes an int for the parameter and not a string.

hello,
I'm writing a Android App (java) - but I guess this question is pretty general, and isn't java-specific:
so I have an Array of Elements
and I let a random-number-generator pick one array-element randomly and hand it to me.
now I've also built in a "score"-field into each array Element
so what I want to do now, is that the random-number-generator takes the array's "score" in consideration, and gives me the array-elements with the higher/lower scores with a higher/lower probability
I dont want it to ALWAYS/NEVER give me the elements with the highest/lowest score - just with a higher/lower probability
I hope I could describe my problem in a proper way....
does anybody know how to achieve this?
(as I said, i use java, but i guess code in any language - or even pseudo-code would help me out)

*bump*
anybody?

Try this, it's in C# but it's pretty close to Java.
You cannot directly weight the random function so you have to use a different method.
By applying a weight to each item in the array, then using a random function to select using the weighting values, the results of the selection can be swayed.
The weighting values are relative to each other.
Using the values in the code, 'B' should turn up about three times more often than 'A'
The only object that may need some explanation is Random:
http://msdn.microsoft.com/en-us/library/system.random(v=VS.80).aspx
Code:
using System;
namespace RandomWeighting
{
class Program
{
static void Main(string[] args)
{
char[] Select = new char[10] {'A','B','C','D','E','F','G','H','I','J'};
int[] Weight = new int[10] {10,30,25,60,20,70,10,80,20,30};
int[] WeightSum = new int[10];
int i,j,k;
Random Rnd = new Random();
WeightSum[0]=Weight[0];
for (i = 1; i < 10; i++)
WeightSum[i] = WeightSum[i - 1] + Weight[i];
for (j = 0; j < 70; j++)
{
k = Rnd.Next(WeightSum[9]);
for (i = 0; k > WeightSum[i]; i++) ;
Console.Write(Select[i]);
}
Console.WriteLine();
}
}
}
Output:
Code:
HEFIBHHCCFBCAEFFDHACHBEJHHFDFIDFEDFFCHHDJBIDJEHHFHCJJJBHJGBDDGFDDFHHHB
Note the low density of A and G as opposed to H
It is just a sample at random, but 2 'A's and 7 'B's roughly matches the conjecture above, but over a million selections, the distribution is as follows:
Code:
A 30664
B 84187
C 70648
D 168481
E 56529
F 197311
G 28145
H 225764
I 56613
J 81658
If your code changes values in the Weight array then the WeightSum array must be recalculated.

wow, thats a lot!
The only thing I dont understand about the code is this line:
k = Rnd.Next(WeightSum[9]);
for (i = 0; k > WeightSum; i++) ;
what exactly happens here?
what kind of a for-loop is this?
why is there no body?
and strangely, while debugging this line, i noticed that the value of i jumps to some random number in this line - and I have no idea why and how
------
by the way: I've already tried it out, it works pretty good.
although I noticed that the first element always gets picked ALOT, no matter how low the weight.
I think thats a flaw in the algorithm

After the following code:
Code:
for (i = 1; i < 10; i++)
WeightSum[i] = WeightSum[i - 1] + Weight[i];
The WeightSum array contains the following values:
Code:
[0] 10
[1] 40
[2] 65
[3] 125
[4] 145
[5] 215
[6] 225
[7] 305
[8] 325
[9] 355
The Random.Next() function that takes a single integer as an argument is defined as:
-------- Courtesy of MS VS .NET Help ------
public virtual int Next(int maxValue)
Parameters maxValue Type: System.Int32
The exclusive upper bound of the random number to be generated. maxValue must be greater than or equal to zero.
Return Value Type: System.Int32
A 32-bit signed integer greater than or equal to zero, and less than maxValue; that is, the range of return values ordinarily includes zero but not maxValue. However, if maxValue equals zero, maxValue is returned.
-------------- End of Help ----------------
So, we are asking for a random value between 0 and 354,(element WeightSum[9] above). The following code then finds which is the lowest element of WeightSum which holds a value greater than the one we have been given. When this happens 'i' contains the index to use for the selection.
Code:
for (i = 0; k > WeightSum[i]; i++);
The standard construction of a for loop in C is
for(One or more initialisation statements; Do_While_True Condition; One or more iteration statements)
{
loop processing code;
}
If there is nothing to do in the loop body, you don't need it, and you can replace it with the ';' at the end of the for statement. In effect, it is identical to the following code:-
Code:
i=0;
while(k > WeightSum[i])
{
i++;
}
As regards the first element being picked more than the others, have a look at the distribution table in post #3. It is what you would expect for the values given. I assume the difference is either the Random function in Java or some different implementation between C# and Java.
You may have to change some of the code slightly, i.e. change the for() loop to the while() loop above and step though it in the Java debugger to get to the root of the problem.
You can't debug a for loop followed by an immediate ';' The entire for loop is executed to completion when you use debug and try and step through it. To debug it place a dummy statement in the for loop. A breakpoint may now be set on this line.
Code:
int i,z;
for (i = 0; k > WeightSum[i]; i++)
{
z=0;
}

I was looking around in the gpu driver files and I noticed that there was a hidden 5th 533MHz OC in there. I tried to enable it by copying in the "asv_3d_volt_9_prime" table in for the "non-prime" table. I made sure to remove the -1 in the non prime's table so it wouldn't think the extra voltages for 533MHz was out of bounds. I made sure to comment out these crippling lines:
Code:
/*if ((samsung_rev() < EXYNOS4412_REV_2_0) && (maliDvfsStatus.currentStep == 3))
{
level=get_mali_dvfs_status();
}*/ //a crippling check for "prime" note 2?
I also (after looking at siyah's kernel) copied in the entries for the step4 sysfs variables into mali_kernel_linux.c but my cell phone seems to be bent on not giving me this 5th step.
Sorry again for asking a question that's probably obvious to elite developers. Oh and thank you for answering my question on adding frequencies to the cpu. I now have my own (not copy and pasted :cyclops: ) lines in there to give me 2OC frequency and 1 underclock frequency.

Where's that code snippet from? Anyway it's not related to the limiting if the 5th step.
Code:
static mali_bool mali_dvfs_table_update(void)
{
unsigned int i;
unsigned int step_num = MALI_DVFS_STEPS;
//if (samsung_rev() < EXYNOS4412_REV_2_0)
//step_num = MALI_DVFS_STEPS - 1;
Just comment out those two lines in the DVFS decision making and it should scale up to 5 steps.

They will be "PROKRUCHIVATYA" at one location in the cabin, but with different icons of different information and ... according to the chosen event he or events.
Upper information - the distance to the event, the bottom - time in the scene.
Now click on the icon will get a third of the current screen with an overview of the place, the relevant event, well, or automatically.
On the TMC. Upper infa - distance sobyliya, lower - latency, which makes this event (not to be confused with the overall delay)

Extracting many "long key name" = "value" pairs from DB2's log files
Hello Team!
I have a problem go through it!
Working on extracting some Key/Value pairs out of DB2's log files. I have a file like this:
Code:
[...snip...]
Buffer pool xda writes = 0
Asynchronous pool xda page writes = 0
Total buffer pool read time (millisec) = 66
Total buffer pool write time (millisec) = 0
Total elapsed asynchronous read time = 46
Total elapsed asynchronous write time = 0
Asynchronous data read requests = 3
Asynchronous index read requests = 0
[...snip...]
While I can go and use EXTRACT commands/regexes for only the specific ones I want, it would be extremely tedious to do so. Especially since this spans across various sourcetypes.
Ideally, I'd like to be able to make use of Splunk's(Learnt splunk from mindmajix) "CLEAN_KEYS" setting and have things come out extracted so I can do a search like this without having to configure anything else:
Code:
search {stuff} | timechart avg(Total_buffer_pool_read_time_millisec)
I have this so far.. (copied some values from other pre-packaged transforms.conf files)
props.conf:
Code:
[db2dynsql]
BREAK_ONLY_BEFORE=Number of executions
SHOULD_LINEMERGE=true
KV_MODE=none
REPORT-kv = db2_kv
transforms.conf:
Code:
[db2_kv]
CAN_OPTIMIZE = True
CLEAN_KEYS = True
DEFAULT_VALUE =
DEST_KEY =
FORMAT = $1::$2
KEEP_EMPTY_VALS = False
LOOKAHEAD = 4096
MV_ADD = False
REGEX = ([^=]+)\s+=\s+(.*?)
SOURCE_KEY = _raw
WRITE_META = False
Help me on this!
Thanks
