Anyone else having really bad Bluetooth sync issues with video content on M5? In my case, the audio arrives BEFORE the video frames so it's not a delay but the opposite. Happens in YouTube, Netflix, prime, everywhere. And also not related to wifi or streaming bc same for downloaded content. And occurs with Aptx, aac, or ABC code s.
I hope rooting and applying the android O Aptx libraries might somewhere fix but no go. Any solutions?

Hello,
I have the same problem with the last "emby for android" but not with "plex media" on my media pad m5.

I've searched thoroughly on this and no solutions, only a few other users reporting the same problem.
Got a TV, Blu-ray player, or network media player that supports DLNA? Can you record a video on your Vibrant, and successfully play it on your client device? I think I saw someone say they had success using a WD Live HD Plus...but I'd sure like to get confirmation before I go get one.
I picked up a Samsung BD-C6900 player that ought to do this. Getting the networking set up on both the phone and the blu-ray went extremely smoothly. The Avatar trailer plays over DLNA perfectly. But videos recorded with the phone's camera? No go. They play for a second or two, then freeze, then sometimes pick up again, much farther into the clip, then freeze again. Even on the smallest resolution.
The C6900 is going back, unless I get some satisfaction from level three support in the morning...by the time I got that far tonight, the department had closed for the day.
So maybe I try the WD, or wait until some future time when Samsung finally gets around to doing the engineering that should have been done before releasing product, and spreading hype about Allshare that crosses the fine line from fraud into marketing.
Any other experiences or ideas?

Update 10/1/2010 5PM MT:
Amie at level 3 support did not have any solutions, but was conscientious in taking down the data to relay to development.
I discovered that turning off "record audio" results in videos that play through allshare correctly, excepting the highest resolution mode. Even though they play correctly, there is a notice at the beginning: "Audio codec not support". This notice also sometimes briefly appears at the start of the malfunctioning videos that do contain audio.
I've copied the videos over to Ubuntu and used mplayer -identify to start analyzing them. Nothing jumps out as suspicious. In both cases, the audio format ID is 255 and mplayer selects the FAAD AAC codec. Mplayer plays them all fine.
I tried Twonky Mobile Server in addition to allshare, and it behaved similarly to allshare. It produced a log file in which the most interesting difference between avatar_trailer and the recorded videos is that DLNA profiles were found for the malfunctioning videos, but no profile was found for the Avatar trailer.
I wonder if something is triggering on-the-fly transcoding to happen, even though it should not be needed? On-the-fly transcoding is something that can happen under DLNA, so that broader compatibility can be achieved. It's going to be slow, though, on these embedded processors. Slowness due to transcoding would be consistent with the symptoms. I don't know whether such transcoding would happen on the server end (phone in this case), or the client end. Anyone, anyone? Bueller?
My next experiment will be to burn the videos to disc and see what the C6900 does with them in that case.
Update 10/1/2010 10PM MT: All the videos play fine when burned to disc. So it's purely an allshare issue...but is it on the phone end, or the BD player end? I checked back and found the source of the report that the WD Live worked with DLNA from a Vibrant...but it was not claimed that videos recored using the Vibrant's camera worked. So I have never seen any report of anyone ever playing their Vibrant-recorded videos using DLNA/allshare. Seems like something amiss on the phone end, then...but why, if the video files themselves are OK, do two different DLNA server apps (allshare and Twonky) both fail in the same way?
Next experiment: stream to Windows 7 as the DLNA client.
I would like to capture the DLNA streams, but am not sure how to go about that.
Mods: I see you moved this to Q&A. I think perhaps it would be a better fit in Development, now?
Tried flashing a different ROM, Frankin-Twiz Final. It has allshare removed. TwonkyServer Mobile had Unrecoverable Error on startup. So I restored to stock.
(someone has since posted a dlna.apk in that thread that restores allshare)
I had to reinstall Twonky after flashing back to stock, and after that, it worked better! There must have been an update to it in the interim...
Still not perfect; there are pauses every few seconds, but it resumes from the right spot.
My best guess is that an on-the-fly transcode is happening due to the unusual 32k audio sample rate of the camcorder videos. The client device probably doesn't support that rate over dlna. I bet some client devices do, and would play the videos smoothly.
Hopefully a firmware update for the BD-C6900 player will come along that fixes it.
I acquired a Western Digital Live Plus HD player at Best Buy for $99. With the Vibrant running TwonkyServer Mobile, the WD plays all videos perfectly, even 720p!
I didn't try allshare--no reason to bother, and I like how Twonky stays running in the background and lets you do other things on the phone.
The C6900 is boxed up ready to go back to the store.
This is my second question-post today, I apologize, but this is the final issue I've been trying to figure out.
I thought it could possibly be related to this post about BT audio lag (http://forum.xda-developers.com/showthread.php?t=2606441) but I just disconnected my jambox when this came up and the audio delay continued on the internal speaker.
I use MX Player Pro for videos, and when I resume a video (doesn't happen every time), the video lags behindthe audio anywhere from a few milliseconds to over 3 seconds. It isn't enough to pause and then resume, I have to exit to the home screen and kill the MX Player background process. Then I can reopen the app and play the video. Sometimes it takes more than one try to get it synced again. It's as if the CPU is struggling to keep up.
Has anyone experienced this?
Any audio over bluetooth will have a delay.
It's possible that if you disconnect BT mid play it will still play the audio at the same point it left off so continue the delay.
I'm betting if you play the movie without BT it's fine?
If not, try enabling/disabling hardware acceleration.
What format and quality is the file you're trying to playback?

I never really watch videos without my Jambox speaker, so I have tested it by disconnecting the bluetooth when the delay occurs, and it continues to occur once the sound routes through internal speaker. I haven't tested it by only playing through internal speaker, so I will focus on trying to recreate the problem that way.
The DTS codec from the XDA thread is the updated one which is fully functional with updated MX Player 1.7.26.
I have MX Player set up for HW+ for Video and SW for Audio. I tried HW+ for both and SW for both and it didn't change anything.
The files vary from .mkv to .mp4, etc, depending on the torrent I download. It doesn't seem to favor one file type over the other. Quality wise has been 720p, 1080p, and less, doesn't matter there either.
Like I said before, it seems like the audio is being processed great but the CPU is struggling with keeping the video up. I could reformat my phone again and do a clean install, although I fully wiped the device before installing rooted .136 this time.

Nope, still happening. I just opened a video for first time today, without bluetooth connection, and there was about a half second delay. It sure is annoying.

Then it's either mx player not handling the format very well or its the file itself. Try bs player see if same happens.

I am using RHA MA650 wireless earphones and am experiencing sync problems with audio when watching videos. The audio is delayed when watching videos on the BBC website, and the audio is ahead of the video with YouTube. I don't experience any problems with videos on my Pixel C. Has anyone else experienced this?
So there are a few mentions of Google play music changing from mp3 to AAC. Not as many as I would expect given that this is a big deal imo.
I tested today using the web player on my mac and it was indeed AAC but I have no way of verifying if this also the case on mobile devices too. On android the files are hidden away and cannot be viewed without root. I can see no reason why they would vary it by device but you never know
Anybody have any idea how to verify on an android device?
Would be great if someone could throw light on this. Really want to know whether GPM is playing AAC on Android like their web player. If that's the case, it's indeed a big deal.
Hi,
when I watch videos on my M5PRO (OS version .151) the audio is slightly off.
I have experienced this within the Netflix app (with downloaded videos) and with the MX Player app, also with videos that are stored locally. All is stored on the onboard storage, I have no SD-Card in there.
Any one else has this?
Thanks,
Frank
Are you listening to audio via bluetooth? If so, that could be an issue with bluetooth, which seems to be a little bit buggy for a lot of us. You could try toggling bluetooth off and back on again, if that is the case.
