Running XDA Orbit 2 with Core Player - it's so unbelievebal that this new device...

...is SLOWER than my 2 Years old Dell Axim!
I've been running my Update for CorePlayer to V1.2.2 without any problems. But - i've running the YouTube Function, connecting over WLAN 54 MBits to the YouTube Empire...
There i'll be searching for some videos, thinking that anything has chanced with this new version - tapped on a video - waiting - watching about five seconds - and? NOTHING! Its like before, laggy, struggleing and unwatchable...
why this damn devices is not optimized? why is this expensive thing hardware not able to do, what a two or three year old pocket pc is running without any problems? why we must hack this device to get a piece of performance?
This device is the best, the nicest and the fully featured piece of hardware that i've ever had. i've been a pda junkie since the beginning of this with the crappy WIN CE2.1.
Since Win CE is mutch time gone and the devices gone faster and faster. The good old casio em500 running a 150 MHz MIPS CPU was fast - the well known iPAQ3660 was faster and much better in playing videos or something. Every change of hardware was a change that was useful. After that a MDA2 with a 400 MHz x-scale cpu was mine and it was faster than everything before. MDA Compact was faster, The Dell AXIM Series was fast like a rocket - but then XDA Orbit brakes me like a train crashing in a wall of steel. I thought i've been running this device with a handbrake or something.
The Orbit 2 is a little bit faster - but if there is no video driver the videos are laggy - and that is what i don't understand. Why HTC?!

1. The youtube function is still new to the CorePlayer (I mean the direct youtube support whith available configuration)
2. The lag is mostly because of a small buffer and/or a crappy net connection
3. Unless CorePlayer doesn't suck whith normal (320x240 24~25 FPS) videos, don't complain.
Yes, we know that the drivers are missing, that's nothing new. If you wan't to know the cause check my signature. We heard enough people complaining, and most of us tried to do something instead of (in this case very detailed) whining.
If you knew what to expect, then don't complain, it you didn't... maybe next time you'll check forums/reviews/youtube for more info before buying.

Apple iPhone running Quake 3 smooth like a piece of butter in the sun...

as far as i know iphone got a 600Mhz arm cpu
and a whole different os structure so you cant
really mix it into a compare of polaris and an older dell pda

We feel your pain buddy...
Or should I say, we felt your pain. We've got past that stage already, and have kind of accepted this crappy fact of life - that we've been bent over with a smile. I personally chose this device because there is nothing else to choose from!
On the other hand, HTC makes me really want to get an iPhone, even with its lack of any modern features - it is a device that just works (well, after you've jail-broke it).

I wonder why your facing this problem?!?! CorePlayer 1.2.2 gives smooth flawless video, I've tested in on every video format commonly used.
Have you installed it on your Storage card or Device memory?

Just out of curiosity, will it make any difference?
I have it installed on the device itself, will it get a boost if i install it on the memory card?

Yes, the app performs faster if installed on the Device memory, hence the improved video speeds.

That was a kinda unclear response, i asked if i'll get a boost if i'll get a boost if i install on the MicroSD Memory card, and you reply with yes, you will get a boost from the Device Memory.
But i'm guessing i've done the right thing (installing it on the Built In memory)

Better to install on the device memory. As a rule of thumb install apps on device memory, especially if you have performance or incompatibility issues.
As for Coreplayer, I am using 1.2 with QTv. While it is a lot better with QTv and benchmark numbers are great, it's still not that fluid. When panning in scenes or fast motion, it's still not very smooth. When I check properties I might have 1 dropped frame out of several thousand so I know it's not dropped frames. I have encoded my movie (source is my DVD) at 320x240. It's at 24 fps. I can always try encoding at 30fps and see if that fixes it. But I don't believe fps to be the issue since playing the 24fps movie on my computer is smooth. Any ideas?

[Q] Couple noob questions

I'm not necessarily a noob to android. I've flashed a few phones, dabbled with rooting and custom roms, but nothing too serious.
My first question about these Tegra 2 processors is fairly simple. I want to know if overclocking them makes them more media capable? I have a Droid Charge and had a Galaxy S before it, and both phones were perfectly capable of playing a 720p mkv with nary a stutter. It boggles my mind that I have to convert every video file before I drop it onto the Xoom. It's not a huge hassle but it's rather interesting a single core hummingbird can handle it with ease and a dual core clocked at the same speed has so much trouble.
Second question is this. Is there any development going on for the Xoom Family Edition? I haven't noticed much other than news posted regarding this version on this forum, so I'm not sure. It's obviously not the hit they were hoping it would be, there's a whole 3-4 cases made to fit it, and virtually no accessories for it like there is for the Xoom (docks and whatnot). If overclocking helps without nuking battery life, I'd be interested. I wouldn't know where to start developing, I'm definitely not a skilled programmer, but I would be happy to help any way I could (minus a potential brick, I can't afford a new tab)!

Bump. Any opinions?

Regarding the overclocking the tegra 2 , yes it will be more powerful therefore increasing media playback performance. Although battery usually drops faster you can install set CPU to set profiles for when the screen is off etc...
As for the Xoom I myself am not very knowledgeable about that device so I cannot effectivily answer your question.
Hope this helps!

Remember that the Xoom screen is so much bigger, so takes a lot more juice to playback at same resolution, but overclocked cpu does make a difference for sure. Also, if on ICS, go into developers settings menu and turn off animation or set to .5. Makes a big difference.
The Xoom FE (like the Xoom2 and the Xyboard) don't have unlockable bootloaders and noone yet has found the exploit to gain root access. Hence no development...so far. If you find the way, you will be popular among the owners of those devices.

If you overclock the Xoom it will of course consume the battery faster, as with anything that requires voltage tweaking. The main thing to remember is research the governors that will adjust what clock you're running at and when you're running it. Interactive usually gives the best performance speedwise while Ondemand gives you a mix of performance and battery life.
Your media playback issue could possibly be due to several factors. Processor, RAM, SD read rate, and the media player are the main culprits that come to mind.
If it is the processor then overclocking will most likely help. There is a minor off chance that the Tegra2 does not contain certain instruction sets included on the other devices processor that allow it to decode the Matroskiva, mkv, format as readily.
If it is the RAM, your best bet is to get a task killer and use it to kill everything before you try to play the video. You can also go into settings and go to individual apps to force kill them which tends to work better than most task killers.
If it is the SD card rate, research fairly deeply into the subject because I personally have heard many mixed reviews in regards to the Xoom and higher "class" or access rate SD cards. Eventually I plan on getting a collection of them to run some testing myself for a unified chart, but until then your best bet would be to ask experienced Xoom users, and browse these forums.
If it is the app then try looking around to see what other players are out there. Some people use different decoding codecs than others, and some tend to work better on mobile devices with limited instruction sets.
Mind you, if i remember correctly, the other two devices also display at a lower resolution, which would take less power, and the app used to play the file might not support the larger resolutions as well.
And if you have not already toyed around with your Xoom and hacking it, just as a warning, like all other devices it can be easy to brick. Make sure you have read at least 2 different tutorials on how to do it beforehand as some are much more clearly stated than others.
Hope this helps you some

I hadn't thought about the memory card being the issue. I'm not sure how fast the internal memory card is, but my external is only a class 2, so that could have an effect on load times and everything. I know the RAM isn't really a problem, I don't do much on my tablet, and I've tried killing apps and fresh boots and nothing seems to work. It only seems to use about 450mb out of 1024mb for apps, and out of that only 124 was in use last time I checked.
I have tried many other media players though, including Dice Player which seems to be unanimously the best, and nothing I've tried is able to play an mkv on the Xoom. I typically try downloaded tv shows before movies, which include 500mb Big Bang Theory mkv files and 1gb Top Gear mkv files at 720p. Neither play at all in the stock player and play very badly in Dice or other players.
I can't wait until ICS on the Xoom FE, I'm betting it fixes a lot of my issues. Such as the browser constantly force closing and my wifi slowing down the longer the tablet is on.

Bluetooth audio lag

Hi,
i have bluetooth Logitech Mini Boombox speaker, and i can say i am pretty disappointed.
Listening to mp3 and music in overall is OK, of course.
The problem is with video. Both BSplayer and Dice player give me a lag when watching movies.
Very hard to watch people speak as lip syncing is off.
Can anyone with bluetooth speakers try some movie and let me know the results.
Maybe some other video player plays better. Maybe it is Boombox that has problems (but i doubt).
Thing to have in mind: i tried playing from internal storage and streaming...both audio streams lag.
Aslo: the new firmware doesn't help.
Is this maybe normal for Android in overall? Shouldn't be.
Thx

Check out this thread maybe it can help

If it makes you feel any better this problem is universal across multiple devices. It drives me crazy. It is present on the Transformer prime, TF300 Acer a510 and my Excite 7.7 even though these devices use different BT radios and different BT versions. I have heard people claim that some of these devices don't have video slowdown with BT. They do. Its subtle in some cases and might be overlooked but its there.
I have to assume it is OS related or Tegra related as these are the only things these devices have in common. I have found no way to completely minimize the slowdown in video. I have gone back to using wired headphones for video and BT for music and audio only where sync isn't a factor.
Here is one thing that does help. If you are playing a video that has AC3 audio encoding (most downloaded MKV files) the delay is increased slighty because the audio decoding is done by software not hardware - the video is delayed slightly to keep it in sync with the audio as it is decoded. Over BT this delay, for whatever reason is further exagerated.
For the record: ALL video players on Android decode AC3 in software, even Diceplayer - there is NO hardware support for AC3 on the tegra 3 chip.
To speed up your video you can try this: download the free software Avidemux. Use it to convert only the audio of your MKV file to AAC. By doing this you alow both audio and video to be decoded by hardware - this reduces a major source of lag. On a core i7 PC converting the audio to AAC takes less than 2 minutes on most videos. The video is left untouched - it is not re-encoded.
How to use Avidemux:
In the VIDEO drop down box select: COPY
In the AUDIO drop down box select: AAC
in the CONFIGURE box select a bitrate: 160 or whatever you prefer.
In the FILTERS box select Stereo for the Mixdown. (Why stereo? If you are listening through two speakers keep it simple - two channels are fastest to decode.)
In the FORMAT box select MP4.
In the FILE menu select SAVE then SAVE VIDEO and name your video with an MP4 extension. It will begin converting and will likely take only a couple of minutes on a fast machine.
Now you may find that your video plays fast enough to be acceptable over BT. I still find a faint lag noticeable even with full hardware decoding of audio.

You sure all these devices use different radios or wifi/bt chipsets? The TF700 uses the BCM4329, a very common (and now pretty cheap) chipset that does Wifi, BT (2.1 EDR only) and FM. I'd guess a lot of other Tegra 3 devices uses that one as well. If they'd gone with the BCM4330 they would have BT 4.0 and probably 5GHz wifi as well. The BCM4329 supports this, but it requires antennas for it.
According to someone from Asus (someone here mentioned they'd contacted support about it) BT and wifi shares antennas (makes sense, they're both in the same frequency range) which can cause a lot of interference which leads to abysmal performance, especially for the wifi.
All I know for sure is I'll stick to wired headphones with this tablet...

So it doesn't bother you at all dropping half or more of thousand US dollars on a tablet you can't use wifi and bluetooth correctly? It is this type of atitude that makes Asus get away with things like this and not want to make better products. If they know people will just continue to buy their products, even with known defects and issues, they're not going to change anything except charge higher prices for you to pay. So sad.

Hi,
i will try the trick and change audio stream, just because i want to know if it gets any better.
I am not going to do this every time I know I'll watch a movie on my infinity.
Fortunately my bluetooth speaker also has a line-in jack, so i have a workaround, but i could do that on any f*****.. speaker also. Wouldn't need a bluetooth one
Anyway, just wanted to let everyone interested know, that i have tried same movie with wifi on and off - same result.
This means, yes BT and WIFI share antenna, but if that would be a primary problem, wouldn't it be only logical that when wifi is off, bluetooth gets better. And vice versa. Well, for me that is not the case, which means there is an obvious SW problem. Could be Asus, could be Android. That's the main question here now.
Did this problem get any better with custom roms on TF300?
Thx

No, it does bother me, just not enough to RMA it. I pretty much just use wired headphones at the moment so I can live with it.
I could complain to Asus directly through their support form, but the last time I complained about I/O issues and ANR messages when browsing they suggested I enable software rendering in Internet Explorer 9.
I could RMA it, wait for months and then receive a tablet with the exact same flaw. Unless Asus can say that they've fixed the issue and you can get it replaced within days, I'm not RMA-ing anything. And that's not very likely to happen, is it?

Mixed results
So after reading this thread I decided to try it. I tried it with my bluetooth sound bar and netflix was stuttering, it would have to buffer and when it worked the video was choppy but the sound on the soundbar was fine. But then when I tried it with mine jay bird bluetooth headphones it works seamlessly kind of weird how one Bluetooth device wouldn't work but another one would.

Bluetooth has been screwed up on so many devices for so long - with video slowdown on every Tegra based device I have owned - but it hasn't gotten a lot of attention. So I'm glad to see that it bugs other people too.
This problem was present even on my Tegra 2 based Galaxy Tab 10.1 and Motorola Xoom. So I've been pretty surprised to find exactly the same problem on the latest generation of devices.
It bothered me so much I took an sd card with videos and my BT headset down to Best Buy and Microcenter and tried every device they had, with the intention of buying the one that didn't demonstrate Video slowdown when listening through BT headphones. There weren't any.
I will say that with the Jaybird Freedom BT headset the problem is almost imperceptible, but when you switch to wired heaphones, you CAN notice the difference.Videos run faster and smoother. With BT there is just the slightest general slowdown which I find distracting.
Custom ROMs have never solved the problem for me either. Overclocking has also been suggested, but the TF700 should have a fast enough processor to handle anything I would think. So I kind of think the OS is to blame.
I've learned to love wired headphones and speakers again. I keep telling myself the audio quality is better anyway, while I try not to trip over the headset cord and flip my tablet across the room....

Does the iPad use the BCM4330 chipet? I know it features Bluetooth 4.0. It is ironic that Apple cheapens out on the camera, storage space, and connectivity, but gives a superior wifi/bluetooth chipset. I would be curious what the price difference between the two chipsets is. You would think Asus would be want to be competitive and advertise Bluetooth 4.0. The standard has existed for 2 years.

So I tried this last night. Here are my results:
Wifi speed with BT off and no streaming: 9.6-9.8 Mbps.
Wifi speed with BT off and streaming music on Google Play: 9.5-9.7 Mbps
Wifi speed with BT on and streaming music on Google Play: 9.5-9.7 Mbps
Wifi speed with BT on and streaming music on Google Play to Jambox: 9.5-9.7 Mbps
Thus I concluded that streaming music over BT to a speaker or headset had no problems or slow downs at all. So I decided to test with video. For this I used Amazon Prime Instant Video.
Wifi speed with BT off and no streaming: 9.6-9.8 Mbps.
Wifi speed with BT off and streaming video on APIV: 6.5-7.8 Mbps
Wifi speed with BT on and streaming video on APIV: 6.5-7.8 Mbps
Wifi speed with BT on and streaming video on APIV with audio going to Jambox: 6.7-7.9 Mbps
Now I think that the BT + streaming final test result being faster was not significant. I ran it at least 3 times to confirm and it was within those limits.
So at least for my personal copy of the Infinity, I am not seeing a WiFi slowdown while streaming over BT. I don't have 40+ Mbps internet, so maybe the slowdown is only at very high speeds and high radio power requirements.

Just to add another data point. My Prime will stream movies with Bluetooth with no sync issues or excessive buffering and has been like that since the day I got it. I'm unlocked and running a custom ROM (AW2.1). My Prime's WiFi is pretty solid (for a prime LOL) and my GPS is DOA.
I have been a big bluetooth audio fan (I stay up late watching movies frequently but am courteous to the rest of the family) for a while and one thing I have found is some headphones lag no matter what is transmitting. A reviewer will very often not notice it if they just listen to music. I've been using my GOgroove Wireless AirBands as my TF201 'phones, FWIW.

It's not an OS or hardware thing, it's a bluetooth thing. Some apps (like Youtube) simply compensate for this audio lag when using bluetooth (and Airplay as well, btw). You can see it yourself, when you pause the youtube video, it will take a fraction of a second for the sound to pause. I haven't seen an A2DP connection (on iOS as well) that didn't have this lag. Video apps need to compensate for it (Netflix did too, at least for iOS and Airplay, don't know for bluetooth either on iOS or Android), so different players may have this problem or not.
What it's worse for though, is for games. That jambox video where the guy is playing a game is just BS.

I hade the prime too.
I have two sony bluetooth music headsets (the mw600 and the hbh-ds220). Both were working with the prime without any problem.
Now with my new tf700 i get stuttering when listening to google music. The music is buffered on the tf700 and it even happens when i have no internet connection. So i don't think it's an antenna problem at all.
i also noticed lag when using bsplayer and youtube when i tried to connect the tf700 to my beamer and stream the audio via bluetooth. bsplayer was worse but i noticed it also in the youtube app. I don't know if it would start stuttering too as i disconnected bluetooth immediatly.
I think the stuttering was a little bit less when i go on max performance. But that's just a subjective opinion.
I think it's a problem with the bluetooth chip itself and thus i have to send it back...

Anyone know if the Jelly Bean update for the TF300 fixed this?

FYI, Asus tech support told me that the bluetooth audio lag issues "will be improved" in a future OTA. I read that as "not completely fixed" so I returned (sniff sniff) my TF700 today while I still could.

Yeah, none on my SGS3 or iPad2 (BT 2.1 even), but I really wanted an integral keyboard with extra battery for those long flights to Asia.
Kinda hoping the Lenovo S2110 can fit the ticket, but might wait for another round of processors...

[Q] I/O-speed improvement

So, the I/O-speed often is the bottleneck for the tf300. I knew this already, just like the most of you probably. It didn't bother me too much, as I didn't have a lot of issues because of it.
Lately I did start to encounter problems with it, because I started to use my tablet for streaming video. The result is that I can watch about 30 seconds of video, have to wait 30 seconds while the device is buffering, can watch another 30 seconds of video, wait for buffering again, and so on.... It seems the device is not capable to buffer while playing video. Well, you can imagine I don't have the patience nor the wish to watch any video till the end under these circumstances.
As I see and know that the network connection is just fine for streaming video capabilities (it works fine on my laptop and phone for instance), I am pretty sure the problems I have on the tf300 are due to the I/O-issues.
Now my specific question is: is there any solution or workaround to avoid lagging video streams because of these I/O speed issues?
And on a wider spectrum: Is there any way to improve overall I/O-speed performance on the tf300?
Any help is much appreciated.
FYI: My tf300 is rooted, but not unlocked. I prefer to keep it this way, unless there is no option at all to get around these issues without an unlocked device.

So, the I/O-speed often is the bottleneck for the tf300. I knew this already, just like the most of you probably. It didn't bother me too much, as I didn't have a lot of issues because of it.
Lately I did start to encounter problems with it, because I started to use my tablet for streaming video. The result is that I can watch about 30 seconds of video, have to wait 30 seconds while the device is buffering, can watch another 30 seconds of video, wait for buffering again, and so on....

i/o can be a problem but this is a bit extreme even for a tf300, what kind of bitrate has that video? raw 4k?

:laugh: No, it is not raw 4k.
The video-stream has a bitrate varying from 0,8 to 1,5 Mbit/s.

Those youtube videos don't play well on my tf300 either, I always have to 'untick' the HD or HQ button in the videos to play them smoothly.
Do you run stock Android with latest OTA updates on your tf300?

I do run stock indeed. Only rooted.

Well, I'll give it a try by completely factory-resetting my tf300. I doubt it will make a difference, but without trying I'll never know.

Resurrecting I see this thread was never resolved, and if the streaming was addressed elswhere I couldn't find it.
Picked up this tablet recently, 4.2.1 rooted stock. Youtube streaming is unwatchable in HD - not enough buffer, but handles HQ or lower fine. Can stream 1080P fine on my desktop, and HD fine on my Razr I and Arc S. Which makes me question, why the inability to cache enough of the video on the TF300T?

Learn from linux
Hmm I stumbled across a few articles, how to improve linux for netbooks. Some involved lowering the writeback to get better I/O-speeds while batterylife gets improved. Maybe one could figure out how much of this applys with Android and the eMMC drive in our tablet and tweak it accordingly.
Best regards.

I had no issues with surdu_petru's overclocked kernels, got around 10000 i.o (sio scheduler) in quadrant, in saying that that kernel got me a score of 7100 on quadrant overall which must be close to the best for tegra 3s?

Twitch streaming performance

So I searched the forum for 'Twitch' and wasn't able to find anything, and I'm seeing spotty answers to whether or not the MK 808/9 can handle streaming from Twitch.tv. I'm OK with fiddling with firmware as well as going Ethernet in order to get the results I'm after, but can anyone give me some real world information on how well these devices handle streaming from Twitch at 720 or 1080? I've spent a lot of time looking for solid answers to this question and I just can't seem to find anything.

u can watch 720p without a problem, but 1080p doesnt work.. too much stuttering
i increased cpu from 1200mhz to 1416mhz and its getting better, but unwatchable (maybe it works with 1.6ghz, but u will need a good cpu cooler, dunno )
so... if the twitch user streams in 1080p (or even higher) and u cant change the resolution.. you´ve got a problem.
iam using finless 1.7c firmware with 2dark4u 1080p Kernel, but im thinking in few months u can watch 1080p without a problem.
btw. 1080p Youtube videos work absolutly fine.
Edit: im using MK808
