Heyho,
I noticed a really annoying problem the other day when I was watching an episode of The Mentalist on the bus.
First of all a list of what I used when the problem occured
- X1i flashed with Itje's Touch-IT Xperience 3.01.
- Sony Ericsson HBH-IS800 Bluetooth headset
- A 230mb 45-minute 800x480 h.264 video file, packed in an mp4 at 500kb/s.
The problem that occured is that when my bluetooth headset was connected (and playing the audio), the video would lag like hell, e.g. 1 fps or less.
When I disconnected the bluetooth headset and used my wired 3.5mm jack headset, there was not a problem at all!
How do I fix this!?
the same thing happens when i use my hbh-ds980 for watching videos..
what i did to resolve this issue was to use the Super video convertor by eRightSoft (freeware) and convert my videos to MP4 with the "Hi Quality" and "Top Quality" boxes checked in the Video options. so even if i convert videos at 23 fps at 800x480 resolution, video and audio play smoothly through A2DP.
Happens to me too, I use the Motorola SoundPilot S705 and with bluetooth headsets the video lags, while with wired headset quite smooth.
I watch Divx video encoded for PC playback with coreplayer...
update:
Does this has anything to do with the issue? the bluetooth audio bitpool:

i will try tonight when i get home.
I will test those advanced config settings and see what it does.
Sounds fine now, but doesn't fix my problem. Who can tell me more?

What is "Fine" now? better sound? did you reduce o increase the bitpool?
I increased the bitpool and I feel the sound is better, less crackly. Still, it's not the answer to my prying question.
Hallo,
I have the same problem after download norti roms nX1i v1.03 and 1.03 Did you solve it?

Nope, haven't found a fix yet. It's still too slow. Nobody had an answer..
did you ever figure this out?
i just bought a bluetooth headset (jabra bt3030) and i thought id give it a try with my x1a running the orignal rom, software version r1aa021 / customization version R2A.
As for my experience, i dont have any video lag using dvd movies converted at 640x320 768kbps/64 kbps audio and other videos converted at 480 x 320 500kbps/64 kpbs audio. movies were converted using super and also nero recode 2 and played using the media player and also the panel media player.
the only problem i have encountered once in while when starting a movie is the audio would be out of sync. the remedy that i found out for this is to pause the video and then push play again, then everything audio and video is synched up. i think it has more to do with the bluetooth, phone or headset, i dont know which but i figure this because when i start my movie, the movie starts before my bluetooth headset would like click on and start to play the audio.
i see you are using a customized rom, do you think that could be part of the problem? too high of a resolution? i didnt notice much of resolution difference between video converted at 800 x 400 and 640 x 320, 480 x ??? at the same kpbs. then again im not a big hd buff and my eyes arent as sharp as others. the smaller resolution played just as well in full screen mode. i think nero recode 2 does a pretty good job at converting videos, a lot quicker than using super and i got nero free with the cheap dvd writer i bought.
hope you got it figured out but if not, hope this helps others.
im using Nokia BH-503 stereoheadset im not having problems regarding to bluetooth and lags.
im using windows media player and of course i convert the video files to smaller resolution like 480x260.
also tried playing 800x600 but acceptable lags like every 15mins lags for lessthan 1 secs with bluetooth headset.
also try to end background task in your phone like antivirus, skype, etc... it might affect the performance of your phone.
U can use Core Player and there is an option to adjust the time synchronization between video and audio.
I've had these problems whilst playing x264 encoded files. I think that they just suck too much CPU power. It's not that the video and audio desynced or anything. It just had a really low fps! (like 3~4)
I got my vibrant and it plays most videos fine. But when I put mkvs on, the sound doesn't work. The video is fine but there is no sound. Anyone else experiencing this problem?
I was having the same issues with my 720p .mp4 files, using AAC audio (mpeg AAC audio @ 4800Hz). Even when resizing them for the Vibrant, and demuxing the audio, the sound is slowed by about 120% and sounds like demons in hell, eating saltine crackers.
Yea my problems are with aac audio as well. Im thinking of getting it exchanged. But if its a vibrant problem then...
I have a few .mkv files that play just fine on my Vibrant.
This is what VLC says about the audio
Codec:mp4a
Stereo
AAC Extension:SBR

Exchanged? LOL
It's the video player. It supports a myriad of formats, but it's not perfect. It's a little wonky too with h.264 video with odd "b" frame rates, as well as AAC audio at non-standard bitrates. With as much video being encoded and containered in MKV, given my experience with the format, it's quite miraculous that it plays as much as it does. This is as much a problem of how people are free to container MKV in whatever way they choose, as it is a problem with Samsung's built in player.
I have a few terabytes worth of video on my media server and lan here, and it's played most of what I've thrown at it so far. What little it hasn't played correctly Rockplayer ARM7 has been able to play.
This just on a select group of my videos, but a few of them don't have audio working in the stock video player and Act I. The video goes, but not the audio.
In Rockstar Player, the suspect videos played just fine.
Any reason why this might have happened and how to fix it?
my guess is that the suspect videos are coded in 5.1 or 6.1 surround. The stock media player doesn't support this. You could demux the audio to 2 channel and they will probably play fine.
I thought about this. It shows it as 2 channels, so that can't be it.
The audio bit rate could be out of range for the internal decoder. Try checking that. Other than that, I dunno.
The problem is coming from the lack of support for surround sound audio streams. When you encode your videos for your xoom, make sure you set the audio to stereo.
Yes.. but what about pass thru over hdmi. Someone has gotta try that one out. I've been meaning to test out 2 channel ac3. Its possible ac3 is a no-go overall
If i try to stream videos online, I usually stream at 640x360 because the 320x180 option has bad audio. When I do, the video lags behind audio so much that the audio sometimes stops playing whilw the video trys to catch up. However, when I play the exact same video downloaded on my sd card, I can choose h/w decoder which solves all my problems and my video and audio never go out of sync. Is there any solution to this? On stock rom with no mods. Tried all s/w decoder options in mx player, still no better results.
