[Q] A2DP (Bluetooth Stereo) Lag - Xoom Q&A, Help & Troubleshooting

I am experiencing A2DP lag of about half a second on all ICS roms that I have tried. Anyone else have issues with bluetooth stereo lag?
edit: A2DP works fine in stock Honeycomb.

yes, I also experience this lag on Team EOS nightly #45 (umts_everest) when playing videos using mx video player. The lag in music isn't really noticable (since there is no visualisation) and I haven't tried anything else (as my A2DP-Device is my car stereo and I usually don't do fancy stuff while driving...)

Yes, I believe there are some audio issues to resolve. The a2dp is likely tied to the new wifi driver, simply put. But I think there are larger audio issues yet to be addressed.

Bluetooth Lag Solved !
I had a same problem and I was playing with it for a week . I think I figured it out . Here goes . To play PERFECTLY synchronized Audio video on BLUETOOTH , your video has to be converted in such manner that no extra codec is needed to watch it . Meaning your original video player has to recognize it with original HARDWARE ENCODING . When you Convert video it has to be COMPATIBLE with xoom NOT .AVI and MP3 . It has to be h264 mp4 video and AAC audio . ( That's the one that works perfectly ). You can convert it to other formats and play it with other players with they own codecs and Software decoders but Bluetooth will be out of synch .

[Q] Problem with YouTube video playback

Hello,
Suddenly I have a problem with YouTube video playback. The videos start streaming ok, but the appear small (not fullscreen) and very low quality. It used to work fine. The locally recorded videos play nice even in 720p. The problem is with the streaming video player.
I installed the LagFix (which works miracles) at somepoint earlier. Do you think that this could cause this problem? Any one else has seen it? The device is a Samsung S.
Thanks,
Michael

[Q] CM7 alpha 6 bluetooth and m4v video play back issue

So Bluetooth seems much improved in alpha 6 (compared to alpha 4). Still, I have come across a problem: when I try to watch a m4v movie I ripped myself running sound through my Motorola s305 headset, the movie won't play. I can skip around in three movie and see stills. This happens with both the stock video player and mobo player. The movies play fine through bt on Insert Coin 2.2.5 sse.
Has anyone else experienced this issue or (better yet) found a solution?
FWIW, fixed by cm 7 alpha 7.

720p MKV playback

Ok, I've been struggling with this and doing all sorts of research, but I can't seem to piece together a definitive answer. This is what I know (or think I know anyhow)
1) H264 will play just fine from more or less any video player as long as you have the decode mode set right. this seems to be why so many people swear to their particular player (and I've tried so many, moboplayer, dice, etc etc.)
2) H364 is just pure crap because Tegra2 just can't handle it. Something with proprietary codecs or some such.
Now, experimenting with different HD files over the time I've owned my TF, some play and some don't. I've heard others claim otherwise. If anybody can guarantee they can play ANY , really ANY HD mkv file (H364 without re-encoding included) I'd like to know what ROM/app you're using (and I'm sure a lot of others would too). I'm sick of having to pick out/convert my movies all the time.
I'd really like to put this thing to rest.
I hear ya I dont want to re-encode my library either but becuase I cant stand not knowing I have been doing some testing to see what the problem is with not being able to play all files. I have discovered that that the Transformer does not like 5.1 channel AAC audio. I can encode any video to MP4 and it plays great when I set the audio to stereo but when I try with 5.1 AAC MP4 files it no worky. 5.1 AC3 seems to be ok. I too have tried many players from the market and get different results with each one using the 5.1 setting (such as stuttering or lagging or I think it was BS player would only play the rear channel audio) but setting my encoding output to stereo they all play fine. I was on the Google Android Developers site and it stated stereo only was supported for honeycomb so maybe the ICS upgrade will fix this issue? In the meantime I plan on continuing testing different bit rates and audio settings to try and get to the bottom of this. Sorry in advance if this did not help you.
MX player- plays anything i throw at it. make sure you get the Arm7 codec pack too.

I like very much the MX player and it is true it plays mkr videos fine but I do not have sound... I have the ARMv7 codec pack (only this one) do you get sound?
Instead, to play and hear mkv I use DicePlayer Ad. with Dice player plugin for tegra2.
(I am unrooted)
Use software for audio (but hw for video)

The problem with this is that most players out there only let you use one decoding mode for both video AND audio. what player lets you do what you're saying?

Mx video with the codec pack as said previously.
I'll be sure to try it once I get home.
MX player will play the movies just fine but the issue is with the audio. The Transformer has a problem playing audio encoded with 5.1 & 6.1.

It worked great! thanks a lot!!

Bluetooth Lag with video SOLVED ! ( I think ) :D

Ok . Lot's of people on many forums are saying they have Bluetooth lag with video . I think that whole trick is in conversion . Video has to be compatible with stock player H.264 video and AAC audio . ( Avi and mp3 converted xvids will play fine with other players , but bluetooth will be out of synch ) Try that .
Edit : Dice player plays perfectly synched any format , but my controls on headset don't work . Only sound up and down .
Dice player also solved my Bluetooth speaker lag problem.
Thanks

If you have installed custom codec it should work properly. If you are getting poor audio quality the issue might be with audio itself.
