Updated Voodoo5 Kernels for USCC Mesmerize

I'm going to put a link to this here, because it's relevant to the Mesmerize, but resides in the Fascinate forum. IMO, the Voodoo 5 kernel is awesome and should warrant some attention in the Mesmerize forums.

Nice! Finally got our spot on the forum.....this should help a ton! We should compile a list of all threads that belong here, i know it has been confusing to keep everything straight up till now.

Custom boot animation to go with kernels
I posted this in response to some questions in the other forum so I thought I would paste it here also.
OK, back at the house so here's a quickie on custom boot animation that you can add while using these kernels. I'll post a link so you can check one out.
First, you will will notice it's just a zip file named bootanimation.zip. It is a zip file that is NOT compressed. So when you zip your files up, remember to select store for compression level. This tripped me up for an hour when I first tried this out.
Inside is two folders labled part0 and part1, and a text file named desc.txt. Part0 is the first part of the boot animation that is run one time. Part1 is the part of the animation that can loop over and over depending on how long it needs to and how long it is told to. These two parts need to flow together to look good, so be mindful of this. Also, you don't want to make your boot animations too long. They take up space that can be very valuable on phones that have little to begin with. Ours don't have a problem, but some do.
Inside the folders is a series of PNG files. They are named and numbered. Keep it simple. These are boot_000003.png on up to the end. Make sure you have the zeros in front to keep the spaces, otherwise they could get played out of order. Keep you png files the same specs as your phone. Ours is 480 x 800 pixels. Make sure you work in pixels not inches or cm.
The desc.txt file can be a little confusing at first also. It's just numbers and letters. This particular one looks like this:
480 800 30
p 4 0 part0
p 0 0 part1
That just tells the phone it's looking at pictures that are 480x800 pixels and it's going to go thru them at 30 frames per second (15 is commonly used also). I'm not sure what most of the rest is for other than part0 and part1, obviously, but the second 0 is for looping. 0 tells it that part1 can loop infinitely if need be. So it will continue to play as many times as it needs, until the phone finishes booting.
This particular boot animation was a quickie that I downloaded from UOT Kitchen by going through the process of not selecting anything except the boot animation, finishing the build as a cyanogen based ROM, and the downloading the package. Once it was done, I just modified the png's and the txt file and it was ready. Stored it in a zip file and I put it on my sdcard. From there you can just move it to /system/media. I just use root explorer to do this, but others may want to push the files. Do it however you are comfortable. Once there, all you do is reboot and as long as your kernel is compatible, these are, then it will play the bootanimation.
This is the nexus one's colorful x. Nothing fancy, just a quick one to show you how it's done.

[Q] how do i make boot animation from avi?

i found the coolest thing ever, its avi and almost a minute long. i really want it to become my boot animation, i really dont have any idea how to do it. does anyone have any suggestions for how to get this done? ps - the avi has audio too, and that would be even more awesome to include.

You can create a boot animation from any type of video format even if the format is in flash (swf) what you need is a programs that convert videos to either. Jpg or. PNG file (boot animation can be done using only those two formats) ..... about adding sound to your animation yo need to know if the ROM you are running right now is capable to do audio @ boot if not you wont be able to make it work with sound.
Send from My Draken X

Okay thanks, I'm on it.

only .png picture files

Not sure this is right, I have saved the sequence as jpg images - 1418 of them - to a folder size of 58.4 mb with each image sized 704 X 400. Do they need to match droid x screen size to fill screen? And does my desc.txt really have to be 1418 plus lines? is there an easier way?
Thanks for any help with this, if I can do it I will post it so others might decide to use it.

Wait, what?

the desc.txt file will have max prob 5 lines
my custom boot animation txt looks like this exactly, but yours would prob be a little different
480 480 15
p 1 0 part0
p 0 0 part1
(480 is the width/height; 15 is the fps; 1= #of times that part loops, 0= not freeze on last image of fps unlike the liberty boot animation which would have a 10)
part0 is a folder that contains the images that would be the non looping part, and part1 is the looping pictures folder
the .png is the file extension of the pictures

OH okay I get it. Can the fps be higher? Like 25? And can it not loop? It's like a minute long.
Does the phone start after the boot or when its ready? Like if the boot animation was too long would the phone start without showing it all? And do jpg files not work?

no you dont have to add 1418 of lines create , download one of mine bootanimation and decompress the zip file you see how they work... plus DO NOT USE the NOTEPAD from windows (dont know way but android doesnt like .txt created by this notepad) and download notepad++ from here [url="http://notepad-plus-plus.org/release/5.8.7]Notepad++ (Free)[/url] use that notepad to modified the desc.txt

Okay I think I can do that, going to tackle it after a break.

Okay can't get it to work right. Only plays 2 of the 20 folders, and its choppy. Changed the frame rate to 50 because it played slow. Desc.txt looks like
480 854 50
p 1 0 part0
p 1 0 part1
etc on up to part20
And when it played the aspect ratio was jacked up.
Tried four times.

1450 frames is way to much for a Boot Animation (sorry if i didn't mention that before) max i have run is 390 frames @ 120 an still running very tide to the end, i dont know what app are you using to create you frames but if that app give you the options to make for sample 500 frames out of the clip you have that will be better....from there you can start your testing stage and deleted as many necessary frames to make your animation run smooth
P.S. you don't need to create 20 folders for your animation 1 folder is enought for it, 2 folders is more likely when the 2nd folder contains a loop of the animation in question

Oh. Crap. I read a thread said no more than 3mb per folder. The thing is, I didn't want to loop it.
Let me try this,
Can I make a boot animation that's close to a minute long with an avi as the source, have it play full screen with audio and look good? And if not, how close to what I want can I get?
I'm on apex 1.4.1 and I used avidemux 2.5 to make jpegs from the avi selection.

actually that really doesnt matter cuz i have some animation over 10 MB in a single folder and still working like a charm.....well like i said 2 folders is more like doing a loop out of one of them, having an AVI as boot animation that will be sweet is Google implement that feature in near future on Android using avi, mpg2 or mp4 as boot animation.
i heard (not sure) that Apex CAN run Boot animation with, i have no way to test it cuz im Running Liberty 1.5 (1.75 very soon) ....
P.S. if you want i can help you out with your animation just send me the Link of the video and ill create one and you can have that one as a reference for future animation of yours

well you can have it be a minute long if you want, but i think that is a long time personally, my custom one is pushing 15 seconds and i think it is long. i was told audio doesnt work on liberty rom. the audio must be named "Android_Audio.mp3" without quotes. it is going to be in the same folder on your phone where the bootanimation.zip is kept, /data/local make sure that the audio file is not in the .zip. the desc must contain a line that says "part 0 1 android" also without quotes. btw 1400 frames is not at all recommendable

I know apex can run audio at boot, 1.4.1 boots with the thx sound playing. I will send you a link later this evening with the avi. And thanks.

I could go with it being shorter, and it doesn't have to include audio, but I know it can.

[Q] Issues with boot animations (need a themer's advice)

Hey guys, I have been creating some custom boot animations, and particularly the one located in my signature (revolver 4 boot animation) has some quirkiness to it..
It seems to want to stop playing on a certain image (around 57 of 69 images, something like that). I have checked;
My desc.txt file (all is in order and even swapped out some known-working files as a test, only modifying the resolution/fps line)
The image names and sizes (no numbers skipped/duplicated, no anomalies, all images around the same size of 47KB, all filenames are 5 characters, all PNG format)
I even copied the part0 folder and renamed it part1 and added a part1 line to the desc.txt file to allow it to change to try and get it to loop, it will loop the first 'part0' folder (even playing the images that are usually cut off) but as soon as it reaches part1, it hits the 57th (or whichever file it is) and goes blank..
I am using VIM to edit text and 7zip to pack the files, though that would seem to be OK since if either one was a problem the animation wouldn't play to begin with..the file is in my signature if anyone wants to play around with it and help me out. I can't seem to figure out what the main problem is- so the compromise is either have part1 folder, and/or loop the part0 a few times (haven't even tried but suspect it will go blank on first repeated loop), or have part1 added, add a part 2, etc. to allow it to loop (or just add another 'p1 0 part0' in the desc.txt). And btw, I have tried;
Code:
800 700 20
p0 0 part0
It won't play but once, even though the first 0 is by all accounts supposed to make it loop indefinitely..so, I'm at a loss.
Any help would be greatly appreciated.

I am having a pretty big problem with bootanimations as well but mine will not even run once. Super frustrating. Even when i take a working boot animation and swap out the photos with the same resolution it does not work.

There is something funny about bootanimations- I think you have to use the store function, so that it isn't compressed. Also, maybe the old fashion zip would be compatible- 7zip might not be? Isn't that a windows thing?

Using WinRar and Store... Probably something to do with the depth of the pictures or the encoding on them

The red flags are flying- It has the same first letters as windows and it's not open source.
Try taking a working bootanimation and re-arranging/re-numbering the images. If it works, then it's your images. If it doesn't, go open source.

i got it i forgot to flatten my images in photoshop. i feel a little stupid

This is the first issue I've had with it..t may be that I converted the mages from an animated GIF into several frames and then n photoshop saved them as PNGs, but I have other animations that I have created that run fine;
You do need a unix-friendly notepad, like notepad++ or VIM, and yes I pack the files so that they are simply stored; like I said, they play, they just don't finish the animation cycle..and I have heard that there is a limit to how many files can be in a folder, but that it was well-above 70..I have 69..so should not be an issue. Anyone tried my boot animation? It still plays and looks cool, but doesn't loop like it should.

Hey luna this might help its the desc file i used to finally get mine working
Code:
1280 800 20
p1 0 part0
p0 0 part1

Click to expand...
Click to collapse
The code means;
1280 800 20
This is resolution (w x h) and the fps (how many images cycle per second)
p1 0 part0
p1= play once (p5 would be play 5x, p0 is play indefinitely), 0 = 0ms delay between initiation and first image and part0 is the folder for the images..
My problem is this; my image files are 800 x 700 and play at 29fps, so first line is obvious- 800 700 29
second line is p0 0 part0, where the image is supposed to run indefinitely. It does not though. It runs once if I use 'p1 0 part0', but does not play all the way through. Yet if the desc file were not right at all, it wouldn't play it would be blank. So I have the desc file compiled, properly otherwise the image in part0 would not even play..the problem is the images do not fully cycle..I appreciate your help but it seems I know more about these files than you do (no offense mate)..I need to figure out why the settings do not run indefinitely until boot, and does not even finish the animation completely..but plays and then goes blank halfway through it...
But when I put a duplicate folder, part1, with the same animation images, and add 'p0 0 part1' to the desc file, the FIRST animation WILL play all the way through, then the second one crashes it..
Android is funny about some things, folder hierarchy, capitalization and folder name structure, file size and compression ratio, etc..I can't seem to figure out why one of my animation images seems to crash the animation altogether..halfway through.

you probobly do know more than me about it as this is the first boot animation i have worked on. Bud i did know what everything in the code meant. And i have looked at quite a few boot animaions in the last few days. It seems to me that the standard workaround is that if you put only the first frame in part 0 with "p1 0 part0" then everything else in part1 with "p0 0 part1" it may fix it.

Good idea...I am going to give it a shot, one thing I have not tried yet is splitting the part0 folder up into multiple folders, I have some doubts that will work but at this point it is worth trying I'll let you know if it solves the issue.
EDIT:
Nope...couldn't even get that one to play at all..and now for some reason my desc.txt file isn't working, I even created one from scratch in VIM and it would not work..blanks screen now. WTF..this should not be this tricky..

png software
could anyone tell me what software I can use to convert a gif animation into a series of png files. I have tried a few freeware converters but not had any luck, or even better a program that can convert any video file into a series of png's so I can skip the gif altogether?

[Q]Am I missing something? bootanimation jpegs not work after editing?

EDIT!!! F*&% photoshop defaults to background again when I save! This is ****ting me to tears.
EDIT: Just had a read of this articleabout photoshop background layer being saved by default after reading this guy's thread here
Short answer is that Layer 1 is an arbitrary assigned value to any layer above the background. Layer 0 is what your image needs to be so simply renaming the default value of 1 to 0 works AFAIK. I will be testing this in a couple of minutes.
Will leave the rest as a reference for everyone else. They may learn from my stupidity. I did use the search button though it just took searching and searching till I found that guys thread above that had something specific that applied to my situation.
Hi,
I have am a confident at Android, I have build ROMs and I have a great deal of knowledge and for some reason the most simplest thing stumps me and that is getting bootanimations to work. I understand how they work and I know its not the frame rate or anything like that it has to be something to do with my export settings? Can someone here point me in the right direction?
I will give you a scenario here and why I have mentioned the above. I can get an existing boot animation that is 100% functioning and working and then I might edit the images, say for instance I am changing the colours. I don't change their size or physical dimensions in any way shape or form (they will even play in the preview emulator perfectly), I flash them to the device and nothing? Blank screen on boot up. It completed the boot and opens the OS, but for teh duration of the boot sequence when there is usually a boot animation working it shows completely blank?
Surely it has to do with my export settings? I'm competent with use of GIMP and Photoshop, I have GIMP 2.8 the latest and PS CS6.
Can someone with some knowhow here PLEASE help me with supply "secret settings" for their export of images?
I read somewhere that the images need to be reindexed? I don't know how to do this? I have edited other PNGs that are non-bootanimation PNGS and I knew I had to uncheck indexing and check the box for R,G,B and that allowed me to edit the image.....but if I check the box for an boot animation image (set to R, G, B) back to indexed; when I close the image and re-open it again its back as a R, G, B image? WTF?
I have heard somewhere they need to be 24bit? I have NFI what that means or where to change it? My version of photoshop only has listings for 8bit, 16bit and 32bit?
Yes my kernel allows for bootanimations. Yes a boot animation was working on my phone!
I can change nothing except the colour of the images; package them in the same location in the zip; Test on the previewer for Windows; load it to the phone -> nothing!
EDIT: YES Permissions are set correctly. I can even change back to the boot animation that I changed the colour and it works perfectly

I read now 8 bits per channel. And there is 3 being that they are RGB, which makes them 24bit anyway? WTF is wrong. I fail hard if I can't get a boot animation working LOL.

Inside The Bootanimation.Zip File
This section is for those interested in finding out how the Android boot animation works. If you just want to install one without bothering yourself about what’s in the file, feel free to move on to the next section, as this one will get a little technical. Though it should be easy and simple enough for anyone to grasp.
While the Android boot animation might appear to be in a video format during playback, it is in fact a little different. If you extract the contents of the bootanimation.zip file to your computer, you will see:
A desc.txt file
A part0 folder (Contains PNG images named in incremental numbers)
More part1, part2 etc. folders (May or may not be present)
As you can see, bootanimation.zip merely contains one text file and one or more folders with PNG images. The animation is played simply by displaying the images in a sequence, and the text file defines how they are to be played. In essence, first the PNG files in the part0 folder are displayed one after the other and afterwards, those in the part1 file – if it exists – are displayed, again one after the other, and so on. All of this is defined in the desc.txt file.
Let’s see how it works in a little detail by taking a closer look at the contents of the file.
The folders
These contain PNG images named in numbers, starting from something like 0000.jpg or 00001.jpg and proceeding with increments of 1. There has to be at least one folder, and there is no known upper limit to the number of folders.
The desc.txt file
This file defines how the images in the folder(s) are displayed during the boot animation, in the following format:
Width Height Frame-rate
p Loop Pause Folder1
p Loop Pause Folder2
An example of a desc.txt file is:
320 480 30
p 1 0 part0
p 0 0 part1
As you can see, in the first line, 320 and 480 define the width and height of the boot animation in pixels for this example. This must be the same as the screen resolution of your device for the boot animation to properly play in full screen. 30 is the frame rate in fps (frames per second) i.e. number of images to display per second.
The second and third lines have a same format, start with p, which stands for a part of the animation and end in part0 or part1, which denotes the folder in which the images for that part are present.
The number after ‘p’ defines how many times this part will loop (repeat playback) before switching to the next part (if present). Specifying 0 would make the part loop indefinitely till the phone has fully booted.
The next number is for the pause, and is expressed in the number of frames, which can be translated into time by dividing it by the frame rate. A pause of 15 for example, would mean pausing for the time it takes 15 frames to play and since the frame rate is 30 frames per second, 15 frames would take half a second.
Translating all of this in case of the above example, the boot animation will play at a resolution of 320 by 480 pixels, at a frame rate of 30 fps, starting with the contents of part0 folder and after playing them in one loop, switching to contents of part1 folder and playing them continuously till the device fully boots.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
NOTE :
A note on resolution: Most high-end Android devices with large screens have a resolution of 480 x 800 pixels, and are referred to as HDPI. Some mid-range devices have a resolution of 320 x 480 pixels and are called MDPI. Lastly, the screen resolution of some low-end devices is 340 x 320 pixels and these are called LDPI, though these are either the really old Android phones or the cheapest Chinese models.
As a rule, a boot animation made for a lower resolution device will run fine on a high resolution one but it will be centered on the screen, with the extra screen space around it not being used. Using a high resolution boot animation on a low resolution device will result in the boot animation not fully displaying on the screen, with its outer parts being cut off due to being outside the screen’s bounds.

These contain PNG images named in numbers, starting from something like 0000.jpg or 00001.jpg and proceeding with increments of 1. There has to be at least one folder, and there is no known upper limit to the number of folders.
The desc.txt file
This file defines how the images in the folder(s) are displayed during the boot animation, in the following format:
Width Height Frame-rate
p Loop Pause Folder1
p Loop Pause Folder2
An example of a desc.txt file is:
320 480 30
p 1 0 part0
p 0 0 part1
As you can see, in the first line, 320 and 480 define the width and height of the boot animation in pixels for this example. This must be the same as the screen resolution of your device for the boot animation to properly play in full screen. 30 is the frame rate in fps (frames per second) i.e. number of images to display per second.
The second and third lines have a same format, start with p, which stands for a part of the animation and end in part0 or part1, which denotes the folder in which the images for that part are present.
The number after ‘p’ defines how many times this part will loop (repeat playback) before switching to the next part (if present). Specifying 0 would make the part loop indefinitely till the phone has fully booted.
The next number is for the pause, and is expressed in the number of frames, which can be translated into time by dividing it by the frame rate. A pause of 15 for example, would mean pausing for the time it takes 15 frames to play and since the frame rate is 30 frames per second, 15 frames would take half a second.
Translating all of this in case of the above example, the boot animation will play at a resolution of 320 by 480 pixels, at a frame rate of 30 fps, starting with the contents of part0 folder and after playing them in one loop, switching to contents of part1 folder and playing them continuously till the device fully boots.

NOTE :
A note on resolution: Most high-end Android devices with large screens have a resolution of 480 x 800 pixels, and are referred to as HDPI. Some mid-range devices have a resolution of 320 x 480 pixels and are called MDPI. Lastly, the screen resolution of some low-end devices is 340 x 320 pixels and these are called LDPI, though these are either the really old Android phones or the cheapest Chinese models.
As a rule, a boot animation made for a lower resolution device will run fine on a high resolution one but it will be centered on the screen, with the extra screen space around it not being used. Using a high resolution boot animation on a low resolution device will result in the boot animation not fully displaying on the screen, with its outer parts being cut off due to being outside the screen’s bounds.

what about these codes :
320 480 36
p 1 0 part0
s 1 /system/media/poweron.ogg
p 0 0 part1
s none
could you explain those ???????
