Has anyone experienced video lagging causing audio to fall out of sync? I've been playing a small variety of .mkv files and some lag and others don't. What's most odd is that the largest file I've tried (24 minute 1.15GB, with subs) works fine, while a smaller file (24 minutes, 274MB, with subs) falls out of sync within a minute and doesn't re-sync until I move the playback head.
I've seen that other Android handsets seem to have similar issues, though the solution was usually to re-encode the file at a lower bitrate, but I don't get why a larger file would work fine while a smaller one would have sync problems?
Both video files I'm mentioning here are MPEG4 (h264), but the larger file's audio is Dolby AC3 48000Hz audio while the smaller one is AAC 44100Hz audio. I'm playing the video with mVideoPlayer and the videos are stored on the internal memory.
Edit: I've played the same file side-by-side on my laptop and phone, and it's definitely the video that's lagging.
Sorry for the bump, but I'd really like to know if anyone else is having this problem, or if there's a solution for it. No one else experiencing this problem?
I went back and tested multiple players mentioned here on the boards. I tested every player using the same file, one that lagged in the stock player and in mVideoPlayer. Here's a rundown of my results:
VPlayer: no lag, no matter what combination of settings used
RockPlayer: lags in hardware decoding mode, no lag in software decoding mode but terrible video quality (artifacting everywhere)
MoboPlayer: lags (in hardware decoding mode?), no lag in "default software decoding"
mVideoPlayer: lags
stock player: lags
I don't know what's causing the lag, but it almost seems like the players relying on hardware decoding are mainly the ones that lag. Not all files lag, just certain ones, as mentioned earlier.
usually, the reason why video & audio out of sync is the bitrate and framerate are inconsistent, in this case, i suggest u using a video tool, with the video tool, there are two solutions for you:
1. you can convert mkv to the format that compatibled well by galaxys 2
2. just import the mkv video into the tool, then adjust bitrate and framerate.
i prefer the first way, the second way you need trying many times.
for myself, i use fox real video converter, it has video audio sync technology
Thanks for the suggestions. Part of my decision to buy the GS2 was the fact that it could play large video files without conversion since I don't have the time to constantly re-encode video files. Will probably drop the $4.99 on VPlayer since it's been playing my files well. Still prefer mVideoPlayer tho.
Is there some way to check if a file has inconsistencies between bitrate and framerate as you've mentioned?
I convert MKV files to play on my PS3 with a great tool called mkv2vob. It can convert a 1.5GB movie in about 2 minutes, so I imagine it's not actually encoding at all. I'm just curious as to whether it would solve your problem, especially with it being such a quick and easy app to use.
http://www.mkv2vob.com/showthread.php?tid=1
Giving mkv2vob a shot, but it's taking far longer to convert than 2 minutes. My ~250MB file is about 25% through video transcoding, and I'm already 5 minutes in. Will report back whether it worked or not, but I don't think I'll be doing this for every video that lags.
Okey-dokey, here's what happened with the video file I converted with mkv2vob:
It output an mpg file that was unplayable or problematic in mVideoPlayer, MoboPlayer, Rock Player Lite, and lagged in VPlayer. Encoding/transcoding took about 30 minutes, and the resulting file was 337MB, up from the original's 273MB.
I guess you could say it didn't work out well. I found it interesting hat the file lagged in VPlayer where before the same file played fine before the conversion.

i don't know how to check the file, when i met this problem, i just import the file into the video tool, by viewing the preview to adjust some parameters
i have the same problem with my neverlocked and unrooted sgs2 running firmware "pda:kf3/phone:kf7": mp4 videos with x264 video codec and AAC VBR audio codec loose audio-video sync. i.e. the video lags behind and you hear people talking before they open their mouth. using xvid4psp 5.0 i experimented with the used audio codec. when recoding the videos to mp4 with x264 video codec and AAC ABR av sync is o.k.. using MP3 as audio codec also works but since AAC is the mp4 standard audio codec i'll stick to that.
and by the way: using another video player like vplayer also works with the problematic AAC VBR videos. since vplayer does software-decoding i suspect a problem with the hardware-decoding layer in combination with certain video/audio codec combinations (like x264 und AAC VBR). the benefits of hardware-accelerated-decoding are better performance and lower battery drain. therefore i want to stick with the stock-video-player (because i asume it is strictly using hardware-accelerated-decoding).
Hello there, I am going on a two week holiday, and want to watch a movie or two on my phone, the files are about 700mb, file formats are .avi and .mp4 .... whats the best player to play these smoothly???
I've found QQPlayer gets the best performance on my hero.
Moboplayer .....
I Think moboplayer is Best .....
Sometimes, the players are only playing videos correctly incoded for your device.
As an example, with Mobo Player(that I found really great) I can't play any .avi video correctly, it freezes all the time, ...
But with .mp4 format I have no problem...
Moreover, some encoded mp4 videos have some video bitrates that are too high, and the player can't decode it...
So, as for me you should try to re-encode instead of trying to find the best player.
The player is only UI about, so it depends on the things you're looking for
I've tried a few different players, and most of them work really poorly on the Hero. RockPlayer plays everything I've tried, but the FPS is usually low, and the audio keeps getting out of sync. QQPlayer didn't play the clips i wanted to, so i can't say for that.
The best playback I've seen was with yxplayer. There were a lot of small artifacts, but the fps and audio was ok. The UI is pretty lousy though.
The simplest option IMO is to convert video beforehand, so it plays fine with the native hardware acceleration.
I can't for the life of me get this to work i have this 1080p AAC/MP4 harry potter movie- works fine on my laptop and desktop- but wont play on this tablet.
Initially when I got the tablet i was excited and installed the gtabcomb rom (for 1.1) this was AWESOME, but obviously no hd video support (which is really what I am after...)
Ive tried CM7, Gtab TNT lite 4.40, Calkulins, and im about to try the vegan rom.
I have the 1.1 boot loader.
Ive tried like 5 different video players, none have worked except for the software decoding on rockplayer... HOWEVER this was 10 fps, and distorted.
What do I do here? I really want decent hd video.
Thanks!
EDIT: Vegan is clear and the audio is working properly all with the default player BUT the FPS is less than 15...
Now what ?
What player have you tried? For me, between qqplayer, mvideoplayer, and arcmedia, I can play just about everything under the sun.
:<
Going to try some other players now, i will make a list.
strangely - after having the video work (sort of ) in the vegan default player... I tried rock player again.
That fails- when i click hardware decode it just flashes and goes back to the video list... software decode does nothing... just black screen.
SO i uninstalled it.
And now the default vegan player doesn't work at all- just says " can't player this video" (or something like that).
So frustrating
EDIT:
Rock Player : Clear video but 15fps or lower, audio but jumpy.
QQ - Clear video imagery but 15fps or lower, no audio.
ARCMedia - Choppy video at 15ps or lower, choppy techoy - audio....
mVideo - "Cannot player this video" (exiting... then im back at the video list much like the default app)
Try moboplayer, but I dont think the gtablet can do 720p or 1080p unless properly encoded specifically for the gtablet - not powerful enough (ie stuttering).
Same
Mobo player with soft decoding works but still 15fps or lower.
What is the absolute best container, format for a 1080p file to be encoded?
Moboplayer plays almost everything I throw at it with very little stuttering while streaming from my home network using UPnPlay but the audio from the gtab is way to low. When I plug in headphones the volume is OK.
I have gone into sound settings on the gtab and the set device volume is always at 50% even after I increase it to 100%.
Suggestions?

Weird. My gtab's sound is the loudest out of the tablets I have available to me (ipad, iconia, and transformer).
Froyo
Are you running Froyo? Had the same problem until I upgraded to honeycomb. Now its nice and loud.
I thought there was absouletly no HD video support in HC :/ Is it possible to get smooth, quality 1080p playback with 1.1 BL + HC (I guess Gtabcomb?)
And how?! DO WANT!
:/
It would seem that even the stock rom does not play my video Guess it might just be the damn video lol.
Media info is saying MP4 container, h264 and acc audio.
:/
zzz
Someone please tell me what is going on, I can't imagine everyone is using these tablets without any video support...
I nvflashed to 1.2 BL - stock. bone stock, no new apps nothing.
and then i downloaded some trailers from here
http://www.h264info.com/clips.html
Now, the damn viewsonic site even says this the gtablet supports these:
S1080p H.264/H.263/ VC-1/MPEG-2/4/WMV9/DiVX 4/5 Video Decode, 1080p H.264/MPEG-4 Video Encode, Supports multi-standard audio formats, including AAC, AMR, WMA, and MP3
AND- the video (for instance the serenity hd dvd trailer on that page above) is:
Video Codec: H.264
Trailer Resolution: 720p (1280x720), High Profile (Xbox 360 Compatible)
Audio Codec: AAC LC
Resolution: Stereo, 48 kHz, VBR 128 Kbps
Why is that not playable?! I tried multiple other formats and nothing works...
I want to see this device in an out of the box way play hd video as it suggests... i can can't it?
Really frustrated, spent 4 hours tonight flashing pretty much every 1.1 rom and then nv flashing to 1.2 and flashing like 4 different 1.2 roms (including illuminate, which looked really promising but just gets stuck and the "Illuminate Android" screen...
Flash videos player (snotr.com) but youtube.com videos do not. (error occured).
EDIT: Just managed to get VitalPlayer installed (downloaded apk on computer and installed) - plays all of the above videos BUT still they are terribly slow frame rates... what am i doing wrong?
So encoding in MPEG-4 makes everything work... smaller file sizes, smooth frame rates... AAC audio seems good too.
Set bitrate at 4000 and I guess this is how ill have to do everything :/
I am currently running C&C 1.5 v6.
Streaming over UPnPlay.
Most .avi files play ok using the stock movie player - sound and picture
When I try the same file with Mobo the volume goes way down.
When I press the volume button up the on screen volume indicator gose from 50% to 100%, but there is very little change in the volume. The gtab volume indicator does not appear.
When I go back to gtab settings the volume has gone from 100% to 50%.
I have gone into the UPnPlay settings and switched between volume and volume DB with no change.
Look i know your trying to help but if you had read a single thing I have posted
* I HAVE NO ISSUES WITH VOLUME *
Just trying to get an hd video (preferably 1080p) to play at a decent frame rate (23.976+).
Thus far no h264 video works... they are all 15fps or lower.
I have found that a 720p h264 re encoded to mpeg4 @ 4000 kbps does play smooth.
However a 1080p h264 re encoded to mpeg4 @ 4000 kbps is (better than just h264) still sluggish, and the audio doesn't quite sync up.
I really just want to know what video container/codec will work best on a stock 1.2 BL T&T Rom.
I was replying to roberto188 regarding my ROM.
Didn't mean to hi-jack thread, I was just sharing my experiences and looking for help.
Well apologies accepted I am sorry for my mini-rage, just really frustrated trying to get some hd videos working on the thing.
Seems I am just going to have to deal without them...
No worries.
For what it is worth, I just switched to GtabComp 3.2 and the audio issues disappeared.

Try using this to convert your videos for the gTablet. http://dvdvideosoft.com/download/FreeVideoToAndroidConverter.exe
It's free and it has a setting for the Viewsonic Viewpad 10 (1024x600, 1.5Mbps, 128kbps AAC, 48khz, standard quality) and they play perfectly on my Caulkulin+Clemsyn Combo v6 (Froyo).
Thanks will do! I found that mpeg seems to work best but i def got hw acceleration working with caulkulin+clemsyn combo not sure if h264 is working but at least the videos are clear and crisp - I will see about this software thanks!
edit:
FYI Just tried the program, it converts them to mpeg-4 anyway just does it really clean, and faster than handbrake.
Good find TY!!!
so does this mean that when ViewSonic says the Gtablet can play 1080p....are they really saying if you convert your existing movie file into another format with different bit rates and special settings then the Gtablet can play 1080P?
My daily driver will do 250 mph and use no gas.......if I push it out of an airplane....
Maybe its just me, but I've been having some odd issues with video playback on my new Tablet S.
Basically, anything that the Tablet natively supports works just fine. But anything that requires using a Software Decoder (like MX Video Player, or QQPlayer etc) goes weird. The audio and the video will become unsynced as the video playback framerate is much lower than the original file while the sound plays at the normal speed, sending it far ahead of the displayed video.
Does anyone have any suggestions on better ways to play non-supported video files?
Dice player has worked for me without any problems. I've heard of problems with sync on MX but who knows, give Dice a try and see if it helps...
MOBOPLAYER.
sent via awesome aRc (rooted 2.3.4)
I'm using BS Player lite, had no problems with avi or mkv.
Hey guys,
Loving my Prime but I'm finding the video playback hit and miss to be honest.
I'm finding them all very buggy and most of them kick me out of the video randomly even without anything else running.
All of the below run perfectly on my friends Galaxy SII so it may be ICS?
I want to play back XVIDs and MKVs with subtitle support.
Below are the players I've tried and their results:
Google Videos:
Reads MicroSD
Plays MKV (some without sound) but NOT XVID
Doesn't support subtitles
STABLE
Rockplayer
Plays XVID & MKV
No subtitle support
UNSTABLE
MX Video Player Pro
Plays XVID & MKV
Subtitle support
UNSTABLE
MoboPlayer
Plays XVID & MKV
No subtitle support
UNSTABLE
How have you guys been finding video playback on this guy?
I play on using this tablet for a lot of video consumption so I'd love to get this sorted.
Thanks for the help!
Dice Player has been gold for me, playing everything I've thrown at it (720p mkv, avi, mpeg). I haven't tried anything with subtitles, but it supposedly supports them.
There's currently only the ad-supported version available, but the ads are small and don't show up at all should you use microHDMI to display the video on an external screen.
MX video player has worked great for me. Try different encoders if something in your video isn't working well (ie, HW, SW, etc). Also, try re-installing if you think ICS broke it.
Diceplayer is the best I think. Plays everything just fine and have good setting for subtitle.
I watch my videos most with subtitle and i haven't had any problems. Easy to change size and if you long press on the subtitle text you can move it up and down. Also have easy access to change the subtitle sync. And the add only shows when the controls are showing. here You don't see the add when the video plays and the controls and status bar hides.
And if some videos don't play properly i say that the problem often is the video file that is encoded strange.
MX Pro works great for me even on my high profile x264 encodes. SW decoder works better than HW decoder (go figure right? I would have thought the opposite) with fast mode disabled.
Edit: I have to agree with Andreas, if you're having playback issues it's likely the video not the player. Encoding is a subtle art, not everyone gets it right. Get your vids from well known sources like Thora.
Thanks a million guys.
MX Player Pro doesn't support HW decoding on the Transformer Prime. At least on mine it doesn't. Dunno why. And its really flakey. It keep crashing out on any file I try to play (XVID, MP4, MKV)
DicePlayer is WIN so far! Thanks for the recommend!
It's playing everything with subtitles too.
The only thing I don't like about it is the background 'behind' the movie is a gradient from black at the top to grey at the bottom so on some movies you've got a grey at the bottom of the picture instead of it playing on a full black background.
Unless you guys know how I can change that I'll be using DicePlayer until something better comes along.
HURRY UP VLC!
HW decoding technically works on my Prime, but SW decoding performs better. Is the option not even available for you in settings? Free or Pro? Also, no VLC...ever. Just no.
OK!
Very happy to report that after purchasing the full version of MX Player Pro EVERYTHING WORKS GREAT!!!!
Many thanks again guys!
XDA ROCKS!

Another vote for DICE. Hopefully they can get their payment issues sorted out.
Dice is the best IMO. I run huge 1080p files and only Dice can handle it without a hiccup. MX Player Pro has a skip every once and a while. Not that big but Dice doesn't do it so it wins.
VitalPlayer Pro seems to work well. It can't navigate to the MicroSD card though.
BSPlayer has worked well for me. I use the lite version and all is good. It handles all video/audio as well has HW decoding for supported video types.
My vote goes to Dice player. It is the only one that I have tested that doesn't have audio lag when I am using bluetooth headphones. Also it plays everything I can throw at it.
And don't forget to instal mx player codec pack for armv7.. In market too.
MX Player will prompt you if it needs a codec pack installed. In the Primes case it does not, it is good to go.
Since I use and like DVD Catalyst 4 to convert my DVD's to video I also use their video app called Movie Gallery. Not sure if it plays all codecs but it sure works great with my converted DVD's
I used to use VPlayer when it was beta/free but now I use vlc for android http://cvpcs.org/blog/2011-09-18/videolan_for_android_pre-alpha
I get my TFP tomorrow but it works on my phone and the OG transformer according to the post so it should work on the prime. NONeon btw at least the OG was NONeon
I sure hope that it does.
video and sound on tv, subtitle on prime
I've tried Dice- and MX player and with both programs I get sound and video on my tv playing avi but the subs will be displayed only on the Prime. Has anyone the same problem or does someone a solution?
Does MXPlayer require an internet connection for the key verification? I saw some reviews that stated it did. Obviously on a wifi only device i may be without internet... Anyone have trouble with this?

You have to use software decoding if you want soft subs, the hardware decoder on the prime doesn't handle them when outputting.
