[Q] Video lag, audio out of sync? - Galaxy S II Q&A, Help & Troubleshooting

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).

Encoding MKV Files for Playback

Hello Everyone,
After much testing/researching, I have finally found the best solution to encode .MKV files to .MP4 for flawless playback on the HD2 using MediaCoder. I have tried many of the other methods and settings provided by others on this forum and many of them were good, but simply took too long or sometimes caused choppy playback on the HD2.
UPDATE 9/6/10
Thanks to everyone who has helped out with new settings and testing out encoding methods in this thread and the entire forum. I have recently had major issues with encoding certain videos in H.264 resulting in audio sync issues, frames, and artifacts. Doing some more testing and help from forum members, I will be updating the settings to what I have been using recently and having absolutely no issues with even on 1080P files. Just remember to use Windows Media Player, it provides the best playback for these encodes!
MediaCoder Settings:
Format: H.264 ( If Possible use CUDA Encoder, much faster!)
Mode: Average bitrate @ 1500Kbps
Audio encoder: FAAC
Audio Format: LC-AAC
Audio container: AAC
Audio mode: Average bitrate @128Kbps
Container: MP4
Resize: 800x480
Effects: Filter by Encoder
Aspect ratio: Keep Display AR
With these settings I have tested 12 different files ranging from 500MB-1.8GB in size(720p quality) and the largest took 34 minutes on my dual core CPU (intel i5). First tried playing the files with HTC Album player and CorePlayer and the results weren't very good and they included a lot of choppiness. After reading some others success with WMP, I decided to give it a shot and I was pleasantly surprised to find that it played the .MP4 files beautifully and without a single hiccup.
Some of you may already have solutions for encoding videos for playback on the HD2, but I have found these settings to be perfect for anyone who wants to encode HD .MKV files.
I want to thank everyone who has contributed to finding the best method of converting/encoding files for playback, but I can honestly say these settings will give you amazing quality and smooth playback, even in the most intense action scenes. Give it a try!
Smack it up, flip it, rub it down,
Sticky this to be seen all around
Very nice find!
Wow, tried many of different settings and this one has worked the best for me so far! Sticky this!
Great find. This is now stuck
Great find. One question though, I have been using XenonMKV to package my MKV files to MP4 and it never takes longer than 10 minutes to do and the videos work flawlessly on my XBOX 360. Haven't tried it on an HD2 since I haven't got one yet. Do the MKV files have to be re-encoded to work on the HD2 or can they simply be repackaged into an MP4 as XenonMKV does?

one reason ud wana change them up is to lower the resolution and bitrate since you dont need it so high on the smaller screen and it uses less battery
I will try it but I don't even convert mkv I just hit up coreplayer but I will keep this in mind
i dont have the option for 800x450 does that just depend on the original aspect of the video? its lost so should be 16x9

You probably meant to say "16:9" which is the aspect ratio. Also, check for 800x400, it should be there.
Depending on your encoder, you might want to see about removing the black bars that are so prevalent on TV shows crammed onto DVDs. The black bars not only take up precious screen space, but they cause the decoder to render them, which is CPU-intensive. Also they cost you in battery life since black is the most expensive color rendering for our screens.
I've tried these settings 3 times on .avi and .mkv amd I either get an unreadable file or sound but no video. the HD2 WILL NOT play ANy of my .avi files and it lso doesn't play some .mp4.
I have tried .mkv files and yes, some of them fail when I try to play them. I kept the same settings from the first post and only changed: Aspect Ratio = Keep Pixel AR.
Which MediaCoder version do you use?

I use MediaCoder 0.7.3.4625 x64. For some of you having trouble playing .MP4 files, what player are you using to open them with? I have found WMP to give me no trouble playing any .MP4 file I threw at it.

Re-encoding the MKV files seems to be the better choice for size and smoothness of playback. At the native bitrate of 3000+Kbps playback is choppy for me even when using WMP. Not only will lowering the bitrate provide smoother playback, but it will lower the file size. The videos I encode are around 500MB average, and when encoding is finished they are no larger than 250MB, which helps a lot since I only have a 16GB memory card.
Using MediaCoder 0.7.3.4625 x64. On my PC I have no problems playing the .MP4. The only issue I get is when I transfer the file to the phone, and try playing it on the phone. I hear audio but no video, but after changing the Aspect Ratio that seem to have fixed my issue.

Glad to hear things are working fine for you. If you don't mind me asking, how's the playback, and what player are you using?
Gentlemen, let me introduce to you AnyVideoConverter - this little baby is free and does the job just fine!
Tried it out w/ some anime. Select file, and hit convert to mp4 - perfect sync!

Wait....250MB...I end up with 1Gb/movie with your settings.
May I ask if you are sure you wanted 800/450 px and not 800/480?

Video: which app on NC?

The built in video app works fine for me, but I prefer RockPlayer.
The built in player also works fine for me. But it really only supports MP4 video files, if I understand correctly. I use Handbrake and the iPod Touch preset to encode for my Nook.
That said, I actually use Act 1 Video Player because it has the nicest 'library' view that groups by folder.
I use yxplayer, no need to encode... plays avi files like a charm.
The built-in player outperforms RockPlayer, which has some audio sync issues.
I use the iPod Touch preset in Handbrake, but I bump the resolution up to 720 x ???, turn off Anamorphic, and set a constant video bitrate of 800kbps and an audio bitrate of 80kbps.
Works well for me. Speed Racer looks gorgeous on this screen.
from my very very few experiments, i concluded that once videos are converted to mp4 (h.264 / AAC) any player is the same (uses the hardware decoding).
with videos in different formats its likely that there will be problems
i agree with nooter on using handbrake's iphone preset modifying the bitrate setting it around 800kbps (for animated movies it can be lower 600kbps should be ok). About altering the size of the movie, only for reducing it (remember the max lines in landscape is 600)
rock player works if u have the latest universal player but you need to install add block because even if you pay for it you cannot activate it
I've found that all the players avail still play back xvid/divx avi's really choppy, going to have to give handbrake a try to take advantage of the hardware decoder...
I was just able to install vplayer from the market (a few days ago it wouldn't install)... some audio sync issues but there are some cache parameters to tweak... anybody had any luck?

Same experience with playing divx/xvid files, choppy sound and 21-24fps video playback. Take that same video and run it through handbrake to convert to .mp4 and it runs great.
Where is the built in video player located? I cannot seem to find it anywhere..
I agreed with vplayer beta from the market place. It's free. It'll play most video formats. I've tested 480p and 720p mkv and both play with high speed setting. 720p mkv video is slow but 480p play fine. It's great with cifsmanager and mounted shared videos.

So, what filetype does that create? What is the Extension? MP4 or M4V? Also, are there any other settings, other than the ones listed above that you use?
I am asking these questions because I am having issues with movies encoded this way playing in the default player. It doesn't recognize the video, so it will not play.
Also, VPlayer plays them, but there is a definite audio lag once you forward to about mid-movie.
Also, as an aside, I am converting ISO files (Direct DVD rips) using HandBrake. That is how I am generating these files. I do change the extension to mp4 from handbrakes default (m4v i think).
Thanks for any help.

There is no shortcut in the App drawer (or Gallery) for the stock video player....I just click the video file (in whatever file manager you use or the Nook Library My Files tab).
Personally I use Act 1 Video player as it will present a list of videos on the SD card and Nook. Although for some reason it list videos on the Nook twice.
Sent from my Nooxus One using Tapatalk
The Act 1 app seems to be the only one that can properly sort videos. I tried the trial version, and it seems to work great, but as intuitive as the in-video touch areas may seem, I just can't get my brain dialed in to use them in practice. I think the built-in NC player works just fine, it's the video file/folder sorting that's nearly impossible to navigate once you have 20 or 30 vids on there along with a few thousand photos.
The media sorting options on Android are surprising lacking, or I just can't seem to find methods to deal with 32 gigabytes of media on this device.
I just did a bunch of conversions from some 720p MKV's. I converted them using Xilisoft video converter.
The settings I used were:
720x420
800k bitrate
44.1khz 128kbps audio
H.264 codec MP4 extension
Plays flawlessly with Rockplayer. No desync on fastforward.
The Built in player IS the best
After many attempts and reboots, I have determined that the Built-in Media player is the best player for videos encoded as specified earlier in this thread...
I tried Rock, and VPlayer beta, but both had very bad audio sync issues.
The Built-in player played all my encoded videos flawlessly. The wife LOVED watching Salt on the Nook during our road-trip. The only downside is the audio on the nook--hardly any volume. Easily solved by a good set of earphones. We are very pleased with the nook.

Check out mVideoPlayer. I haven't tried it on the Nook, but its perfect on my Galaxy S phone.
As for encoding, go with handbrake. Choose the Apple TV preset. Set resolution to custom and width to 800 (handbrake should automatically choose the correct height based on asperity ratio of source material). Set the video quality to constant at 60% (70% is the max you want for HDTV). Under audio, select the appropriate track and select aac with Prologic II or stereo as the encoding. Use the MP4 extension as to avoid issues with different t players.
You can get way more detailed on settings beyond that. It just depends on the material and the playback device. Those settings should get you outstanding video on the Nook. May have to scale back a little if the video is choppy.

After much trial and error, I have to agree with previous poster who said the best player is the built-in player with mp4 files created with the settings mentioned. The other players all had issues with controls and added nothing if the file was formatted as described.
I also had a lot of trouble getting any player to play any file at first. I think installing some of the other players added some necessary codecs. Then after a reboot, everything started to work. Hope that helps someone else avoid some frustration.
Despite a few trials like this, I love this tablet! Thank you xda devs!
Sent from my rooted Nook Color using XDA App
I'm running the free version of Rock Player. It's not exactly the cheapest app out there on the Android market, but if it works well, not a big deal.
Whenever I choose an mp4 video that I've encoded at 848x360, for example, Rock Player seems to default the widescreen video to this resolution, assuming the Nook Color scaled resolution is 1024x600, which means that a high quality widescreen rip at the smaller resolution will default launch with black bars around all 4 edges.
I noticed that the video display resizing has 3 modes,
(1) the default mode as mentioned above
(2) zoomed mode which fills the whole screen, stretching as required
(3) scaled mode which allows the widescreen video to stretch to the left and right edges properly, while maintaining a proper aspect ratio.
So the simple question is, how do I configure Rock Player to default launch video files in the mode (3) mentioned above?

[Q] How can I play MKVs on my phone WITH sound?

I've had a look around and this issue has been brought up a few times, but then just brushed over without a concrete answer.
I have a few MKVs that I want to play on my phone, but that don't have sound.
I've tried with the stock player and with Mplayer.
I've spent the last few hours googling how to convert MKVs to AVIs and whatnot and tried a few times all unsuccessful.
I don't really want to covert them anyway, they all work fine, just not on the phone.
The video plays smoothly, and subtitles show up if it has them, just no sound.
How can I fix this?
OGG Vorbis audio track? Try Moboplayer. I just found out it'll read and play it, subs included.
That's what I'm using, Moboplayer and the stock player.
No sound from either.
I just noticed Moboplayer has a bunc of codecs in the market, do I need to install one of them? Which one?
well i have sound with stock player and mkv.... what sound is it ? DTS, DD ?
i use Vplayer, works fine for me. shows picture sound and subs

Most mkv's contain an ac3 soundtrack.
The SII doesn't like that.
I convert mkv's to mp4 now with avidemux.
With these settings:
- video: copy
- audio: AAC
Works like a charm!
Edit: it's a 'cheap' conversion, it goes very fast because only the audio track is converted.

The Mobo Player app should have an option to point you to the correct codec.
If you don't install the codec then it will only play the same formats as the stock video player.
I use mVideoPlayer, works fine for all of mine.
But I think DicePlayer has the best support for audio codecs, though it's only free for a trial period and doesn't support embedded subs (AFAIK).
I have these installed permanently as one of them usually does the job, I usually try stock first followed by mobo, then rock with Act1 and QQ as backups.
Dice is probably the best but isnt free.
Dice
mobo
rockplayer
act1
qq player
I have tried pretty much all other players, honestly dont waste your time or money on any of the others.
EDIT - sorry I forgot, since moving to this Phone I hace scrapped qq for everything and rock for HD stuff as it doesnt seem to decode as well as stock or mobo, always try stock first.
On my GS2 I do not see any option Mobo Player to point me to the correct codec, any clue?

I like this idea best, it means I can play through the stock player, so I don't need to have unnecessary apps. I do like the stock player.
Is there any quality loss when doing this?
Will embedded subtitles carry over?
Edit: I just tried this, and the file it pushed out had a really low framerate. I could see jaggeddyness in frames.
Mobo is good. it's free.
Mobo's ffmpeg codec support almost all codecs.
but ffmpeg sw codec use CPU more than HW codec.
when playing 720p H.264+DTS mkv. mobo ( or rock ... ) sw codec use almost 100% CPU power.
Stock Player and DicePlayer use only 20-40% of CPU power. ( Audio codec use cpu.. )
SW codec players use lossy color convert and resize routine.
dithering or color loss will occur. ( you can see when playing dark scene )
HW Codec's Pros.
1. Performance ( Can Play 1080p )
2. Battery
3. image quality
Cons.
1. Codec compatibility ( but SGS2's HW codec is AWESOME. )
2. not supported codecs ( RMVB, VP6/7.. )
** dice player 1.1.2 add mkv embedded subs.

Generally I get good results, but haven't tried it with movies yet.
Only 720p series with 25fps, no subtitles.
Back at my desktop tonight I will try a movie with subs.
The file I tried was a movie, 720p, no subs.
I don't know what it's framerate was, but it's pretty damn high. It looks seamless.
When I tried loading it with the app, I got this error. Maybe it is actually important and not to be overlooked?
I answered no.

I answered no every time without much problems. Forwarding in the stock player seems a little slow sometimes but that might be normal.
25 is pretty standard for series I believe.
Converting gives the advantage of hardware acceleration and I do not want to loose that.

Diceplayer give you hw acceleration without converting.
As promised...
Promised a follow-up with an mkv with subtitles.
I must admit I didn't get it to work yet.
Unclear to me if it is even possible, I found some info that the stock player will accept separate subtitles like .srt but I have not confirmed that yet.
Ran across another problem that put me off track.
Tried a conversion to mp4 with a movie but didn't think about the size restrictions.
Could not connect in Storage mode for some reason, so I tried to use SD-cards / usb-otg. No succes with 4 Gig+ files yet ~ using windows which has exFAT and NTFS, neither is working.
Possibly there is a filesystem that will do the job on Win7 and Android 2.3.3?
My research tells me that exFAT is not really available for Android, too tired atm to look for alternatives from the Win side.
Like USB-OTG very much, would like a way to get 4G+ files to my SII that way!
As I said, got sidetracked seriously ~ apologies if I got too far offtopic.

Best Video/Movie Player

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.

[Q] View locks up playing 720p mkv files?

Anyone have any luck getting the View or Flyer to play 720p mkv files? Using mx video player, the files will play for a few seconds, then the player freezes. Shows that it is using hardware decoding in the few seconds before the freeze. If I quickly switch it to SW fast decoding, it will play but the CPU can't keep up so the playback is jerky.
The same files played fine on my OG Epic with HW decoding (obviously I know hummingbird <> snapdragon) and my ET4G. They also stream just fine to my PS3, so I'm pretty sure it's not the files. Anyone else have any ideas?
My workaround right now is just to handbrake the files to 1024x600 mp4 files (which play just fine with the hardware decoder, just adds an extra step that takes awhile even with my 3.2ghz C2Q).
Have you tried a different video player? I hear MoboPlayer is quite good.

I should have specified that I tried mobo and rockvideo player. The others either don't work at all (rock) or didn't handle DTS audio (mobo).
I think you need to compress the files in Handbrake (try keeping it at 1280x720). I wonder if its just the file size that's the problem. It makes sense more powerful phones/devices can handle them. Perhaps the tablet just can't handle it. I haven't yet received my View, but I think the View just can't handle the videos you are using.
I'm using mx player and can play 720p x264 encoded videos in mkv containers smoothly.
