Removing a bunch of preloaded bloatware, I also tossed the My Files app and have been searching for a way to get MKV play back to work. I'm noticing RockPlayer has a way to force System Player, which I would assume is the phones default video player.
I've loaded 3 videos onto my phone, all of which have subtitles. One is a 480p with subtitles, plays fine perfect frame rate, etc. however there are no displayed subtitles. Rockplayer does have subtitles enabled.
Second video is a 720p with subtitles. Video plays fine and smooth, no subtitles displaying.
Third video is also 720p with subtitles and those are working. However, the MKV uses codecs for variable frame rate, which make the video lag terribly in certain parts. Playing this file directly through RockPlayer causes a ton of artifacting and lag about four times more than I am experiencing with the stock player.
Does anyone know how to fix these subtitle problems, or know if there is an additional or better way to load the videos than using RockPlayer?
Edit: And on that note, is there a way/app that will allow choosing specific audio track for a video, or will it always be stuck on the default for the file?
Couple things. The default media player on the epic has ZERO options. You can not configure it as far as I know. However, it plays 720p\1080p MKV files flawlessly. I usually navigate to my video files with a file explorer and open them with the default video player. If subtitles don't work out of the box, then you're pretty much screwed. I'm willing to bet the movie player on the other SGS phones have more options.
Rock player is a piece of doodoo. While it can play MKV files, it chokes on anything remotely high definition. Video playback is all kinds of terrible. Doesn't seem to be able to make use of the Epic's graphics processing.
Until Sammy gives us a video player with more options, I think you're out of luck with subtitles
Just a suggestion but hardcode the subs to the video file.
i too been looking for a video player that can play mkv with the subtitles

You can try rock player, but it's really choppy with high quality movies. I think it supports subtitles. You can try it. It's free on the market.

For some reason, I can't get any of my 1080p mkvs to work. Do they need to be encoded in any particular way?
my problem is that the stock video player wont play any mp4 or mkv vids with more than 2 channels of audio. almost everything i have is 6 channel and wont play on the stock player. as stated above, i find rock player also to be boo boo at hi def playback. i can use headphones and get 5.1 audio, but not through the device speakers. any help?
"5.1" is simulated using a filter, but that method requires headphones to work, so that it can control exactly what each ear hears.

Hey..if you guys haven't noticed mvideoplayer added MKV internal subtitle support for SGS phones..and from what I hear it uses the default hardware acceleration rather then software like rockplayer
austin thats another video player for you to try lol..if not I suggest taking it to the i9000 forum as for now all the development has been there and they had the phones longer.

Oh thank you for pointing this out! I just tested a few 720p MKV files and they played great! Not only that, but it was made by the same person who crated act1 video player. It remembers the position of every video you start and stop. I love it
I was hardcoding subs until I foudn mvideoplayer a couple of days ago. works fine on 80% of external subtitle formats, even allows positioning and font control. it is great.
no more hardcoding subs or worrying about demuxing and increasing audio gain for me!
Cool, thanks for the recommendation. RockPlayer couldn't do HD, so I was looking for another player that was actually hardware accelerated.
And it's free to boot!
I love you guys. This is exactly what I needed.
works perfect with my 720p anime videos with subtitles. had been looking forever and finally this program did the trick. thanks guys
I loaded up an MKV TV show with 720p h.264 and 6 channel AC-3 and it worked flawlessly. I tried playing a 1080p mp4 file with 6 channel AC-3 and couldn't open it. I'm going to try a 1080p mp4 with 6 channel AAC.
If that doesn't work then I'll be pretty disappointed but not by much. I know the S5PC110 supports 1080p recording and playback. It's likely Samsung lowered the DSP clock to save power.

The only point in trying to put on a 1080p movie is if that is the format you already have. If you're ripping your own movies, you should probably rip them to the resolution of the phone. Anything higher than 480p is overkill. 1080p is double the resolution of the phone. Have you tried a 1080p MKV?
For some reason when i try to copy over a 1080p movie that is 6GB, it says the file is too large for the destination device's file system... even though I have about 11GB free.

Thats normal..you have to break it up into either 2gb pieces or 4gb pieces (don't remember off the top of my head)...and it will work...this is actually where Kies I hear is good for..it automatically breaks up the video file for you if you use it. (unfortunately due to TW3 being missing we can't use Kies)
The limit is 4GB and this is due to the FAT32 file system. If android could read exFAT or NTFS there wouldn't be that limitation.

The only 1080p MKVs I have are over 4GB. Even if the phone could play 1080p MKVs, it can't play the DTS audio in the movies I have.
I usually get m2ts contained movies with AC-3 audio that stream perfectly to my Xbox 360 and also work locally on PS3s.
Hi
any news about mkv (h.264) videos whith this tablet?
Hardware is the problem? or android is the problem?
regards
AFAIK, the Vega can't play MKV as this is a limitation of Android (as opposed to the tablet). perhaps in 2.3 / 3.0 we'll see MKV support introduced.
thanks
I can to play mkv with h.264 files, but it's too slow, 4-6 fps only with any players (vital player, meridian, etc)...
saludos
Did you try rockplayer? Have good experiences with it, but haven't tried mkv yet...
You can always use a program like Handbrake to convert it to mp4/h264, which works fine for me.
Remember that MKV is just a container if the base AOSP build of Android suddenly gained the ability to parse Matroska containers it would not magically give you the ability to play High-profile 1080p H.264 video streams, or DTS/AC3 audio that may be contained in the MKV.
Rockplayer and all the ffmpeg-alikes are able to parse the containers but _none_ of them will be able to use the native hardware acceleration and as such will be useless for HD content.

This is the problem
I use vital player, the best for mobii/vega, because I can view all videos with AC3 without problem (divx or wmv with AC3). MKV with vital player are slow too...
The best codec for mobii/vega 720p? mp4/h264? wmvhd? I have a lot of mkv/h.264/mkv...
regards
Funny thing is my first tablet the ZT-180 was able to play mkv 720p high profile with DTS beautifully! It stuttered a bit on 1080p, watchable though. This is on a low budget machine, on the vega it should fly! This was in real player for android by the way. Explain that

I second this. MKV was perfect on the ZT-180's 2.1 rom. Proof that this is not a limitation of android.
hi,
i have installed rockplayer and mVideoPlayer. it seems that they install some codecs because now i can play 720p and partly 1080p MKV videos on my mobii tegra (vega rom + modaco) via the video player that comes with the rom.

Because that tablet its _so_ dodgy that the OEM built in MKV/DTV/AC3 decoding into android (like Samsung/etc) and released it without paying for the licences (for DTS and AC3).
If dolby et al notices then the retailers will get a lawsuit.
Though it does mean that there is Android source floating around China that includes MKV parsing. Latest Gingerbread update add WebM so lest see if that comes with a full matroska parser.

Advent Vega 1.09 ROM + MoDaCo r8
when i play the movies with rockplayer or mVideoPlayer it's slow, too. But with the original player it works fine. Don't know why
Hi all
Apologies for the thread revival. There's no need to use any third party apps to play MKV files, you can play MKVs using the built in media player. I use Astro file manager and do the following: navigate to file, long-press on the file itself, select "Open As", select "Video", then choose the default media player. It might be easier to have the app recognise it as standard, but this method works. I've tried quite a few 1080p x264 vids and the only thing the Vega struggles with is the audio codecs - it supports AAC, but AFAIK it doesn't support AC3.
EDIT: I should probably mention that I use the default 1.09 ROM, modded with MCR R8.
The reason that third party apps probably get a low FPS is that they do not use the Tegra2 hardware accelerated decoding - the built in player does however.
The core Android system actually supports the MKV container format - it's listed on the spec page; I guess implementation is obviously different for each device. As someone pointed out though, the important thing is the codec in use for each video/audio stream; MKV is just a container format.
Is there a program which can link file extensions with app s?
I believe that mVideoPlayer literally just makes the mkv format available/viewable/whateverable in the stock player, so if you install it, you should just be able to play mkvs in the stock player (mVideoPlayer does not have any codecs, so it will only be able to play the codecs that your device can already play)
most devices can play H264 mkv, hell my phone can even play them with one player or another, the issue here is decoding, the vega simply cannot decode h264 high profile video hence the slow framerates as the player has to switch to software.
Suggesting this is possible by switching to the stock player is just nonesense, those that claim to have good frame rates are NOT playing h264 high profile, the hardware cant do it, period, end of thread.
Note: most "ripped" MKV films / tv files (1 gig usually for TV rips 6 gig + for films) that can be downloaded in 720p and 1080p will be encoded in high profile, you simply wont ever be able to play these with decent frame rates without re-ecoding into a codec tegra can handle like H264 main profile - unless the open source VLC team manage to create their own CPU optimisations when VLC finally come out, even then it wont be buttery smooth.
give it up people, you are going to have to re-encode or not bother using it as media tablet.
Anyone struck this hurdle yet ?
Got my tab all set up yesterday... charged it over night, played with it today... thought, right... about to go to bed, might load up a few videos to watch...
Well... I think i was expecting to much for it to play anything out of the box when i went looking for the video player app and there isnt one. You can open files in Gallery... but there is another issue... divx/xvid files with avi extensions do not even show up as being on the device. MKV files do. And they play... all be it with no sound. This started me on a quest... over to the Xoom forums to have a look at those guys... download all of their suggestions... Ok, got the divx sorted. every video player i downloaded would play divx/xvid files with ease. no surprise there... still no files showing up in gallery...
The closest i got to playing a 720p mkv file was with rockplayer... but i ran into the similar issues with rockplayer. when i used it to play the mkv files, if i used hardware decoding, crystal clear picture... no sound. If i used software decoding, sound works... but now the picture it all chopped up and way out of sync...
For the moment it looks like it's back to encoding the mkv files back to xvid... As for this device being able to play 1080p video... i wont hold my breath. From what i have seen of how it plays 720p, it may come in the next update, but for now it even appears to be struggling to play 720p let alone 1080p...
Any ideas, tips or trick you have found that works for playing different video types???
I'm using MoboPlayer which downloads the needed codecs from the Android Market. Tried both divx and xvid, works great.
Also using rockplayer. Will try mobo.

MoboPlayer is supposed to support the mkv container format (haven't tried myself).
Quote from MoboPlayer official site:
"The current Mobo version will not support mkv, mov container format which have built-in subtitle streams, but we will complete this feature as soon as possible."
So, it supports MKV as long as it doesn't contain built-in subtitles. I will try it later tonight and report the results.
mVideoPlayer: mkv + subtitle
Mobo player plays .mkv incl. streams. That is ofc on a Galaxy S phone. On a tegra 2, device as far as I have read, there isn't much luck plying .mkv files as the soc doesn't support them. Go figure.
hi, just wanted to share my experience on finding a worjing solution for my movie playing needs:
- my phone is a galaxy S and i expected tegra2 to outperform it in every way, movie-wise, that's not the case.
- normally i use mvideoplayer but since it relies 100% on native decoding, it wont open most of my files, avi, mkv, etc
- i installed vplayer, rockplayer (normal and optimized), qqplayer, moboplayer, besides the bundled nemoplayer and none was able to correctly decode a 720p mkv (1.5gb game of thrones episode). a couple were able to play it with sound, but they all lagged too much.
- for SD XviD rockplayer worked fine but it doesnt support subtitles, qqplayer displayed subtitles but it dropped frames. moboplayer + armv7vfp3 codec decoded the avi correctly and with subtitles.
- 720p youtube "rips" from tubemate worked fine on mvideoplayer, they use mp4 container and most likely base or main profile.
so... for tv shows from torrent, use avi and moboplayer. for hd content, hopefully they'll be 720p and main profile.
anyone knows what kind of file are the "BRRip" flying around on the net?
cheers.

I had an identical problem: I was also dismayed at not being able to watch a Game of Thrones MKV file!
I gave up on MKV and tried watching a 720p AVI (BRrip in Xvid/AC3) on moboplayer, and it worked flawlessly--even got the subtitles file to work. It's a huge pain in the ass, but converting to xvid/AVI might be the best bet. I'm going to do it remotely on my home PC while I'm at work
yeah, MKV files not working properly or at all is a bit of a bugger, but now i've been converting them into high def (720p) mp4's using some custom settings for Handbrake that i found either here or another forum (can't remember which, lol), works a treat and looks great on the A500!
i looked around for 720p avi files, i didnt think they would look so good.
i still saw some dropped frames but that could have been because i was using CIFS to acces the 2tb hdd on my htpc.
but i still wonder the mp4 BRRips, there's something weird with those filesm even the galaxy S refused to play some of them...
anyway, in short, if available prefer 720p avi...

How did you get the subtitles to work? Did you use .sub or .srt subtitles? And witch program to convert?
I have found that if you use rockplayer in hardware mode and your videos are x/h264 video and AAC audio the results are very acceptable playback
@Ramius71: no conversion, just an SD .avi file with .srt subtitles
the .avi was a 174mb tv episode and the .srt downloaded from opensubtitles
@Yatyas: could you give an example please? .mkv or .mp4? i have several .mp4 that play well but most are ripped from youtube or things like that...

I have found that as long as it is encoded with x.264 or h.264 on the video and AAC on the audio regardless of the wrapper .mkv or .mp4 I get very good performance from the hardware decoding when using Rockplayer.
I have found many .mp4 and x264 files that have AC3 for the audio and I re-encode using handbrake changing just the audio to AAC and everything seems to work well
Hi, I just got my galaxy tab 10.1 and all 720p video files (trailers, music videos, movies) I put on it lagg really bad. I tried moboplayer, rockplayer and MX player. Has anyone been able to play a 720p file on it without lagg, and how do you do it? Thanks.
I'd do a search if I was you. there is either bsplayer lite or diceplayer on the market. those play them OK. that's your only choices.
Agreed, Diceplayer works without any lag at all. All my 720p mkv episodes run buttery-smooth.
If you only buy *one* app from the market, make sure it's this one (you also have to install the Diceplayer Tegra 2 plug-in).
yeah diceplayer is good. just that there is only the trial version on market with 3 day trial. waiting for the paid one
Diceplayer is still a little bit laggy. Tegra2 suckz big time btw. My singlecore galaxy s handles all kinds of hd-videos without problems.
Bsplayer works best. Almost no lag.

I use VLC Direct Pro, works really great!
and you can stream from your pc, so you don't have to put your movies, series of music on your tablet, just stream it from your pc
I use mxplayer and I haven't got problem, although my tab is far from stock rom

Thank you! Bsplayer was the only player I found that handled 720p with only a little lag. When I overclocked to 1,4ghz with the task 650 rom the lag was like 99% gone on bsplayer. Tegra 2 did not run 720p videos as good as I thought it would, and I guess battery life while watching hd movies must be pretty bad if it needs 1,4ghz OC to run it smoothly.
Edit: It was only able to play trailers smoothly. When I tried a 720p movie it was really choppy. I think I have dowloaded every video player there is and none actually play 720p mkv movies smoothly at all, even with 1.4ghz OC it doeson't work. If I can't get 720p to work, I think I will return this and get the transformer prime instead.
Threads like this come up every couple of weeks. Yes, hardware accelerated codec support on tegra 2 is limited. Those looking to decode just any old file they get elsewhere should look elsewhere for a device that supports the random codec settings that are found on video and movie "distribution sites". Those who do their own encoding can find encoding settings that provide great playback quality on these devices at 720p resolution.

If you copy files on without file extension (this also allows files greater than 2GB to be transferred) and then use androzip or similar to add .mkv to the files Default video player picks up the files and plays them fine

With "pick up," do you mean adding to the library? Because the files actually are in the library in my case, the player just says the files can't be played.

Sorry, yeah they get added to the library. Must just be the encoding used within the mkv frame in your case. Either audio or Video codec not compatible within the mkv for the Tab. In the case of the 2GB file I was using it's AVC and AAC audio.

Remove the file extension on your computer. This can be achieved by opting to show file extensions, in Windows' folder options. Then, when the files are on your tablet, use a file manager like ASTRO, IO or AndroZip to re-add the extension. That's it. Depending on the video files, this may or may not work.
Here's the answer to you question

The best solution I've found to play 720P locally or stream via SMB is using diceplayer or BSplayer. I use both. Dice Player kinda sucks at skipping timeframe, only great playing 720P video from beginning to end. BSplayer is awesome because I can skip to any and plus it has its own SMB file browser. That alone is not enough though when playing 720P smoothly, you have to overclock it to 1.4Ghz. I'm using Galaxy Task 8.0 ROM and it plays buttery smooth. Use tasker and setcpu to create some custom condition when to overclock. I set condition in tasker to overclock to 1.4Ghz when BSplayer is active and in SetCPU, I set 800mhz when screen is off and set another for 1Ghz when screen is on. Hope that helps. ^^
Don't use Galaxy Task v9 or v10 because I was having WiFi issue, i dont know if its just my tab or not...
1. In Handbrake load your video.
2. Choose the profile for iPad.
3. On the Advanced settings tab unclick "8x8 Transform".
4. This step is optional if you don't really need a 720p video. iPad resolution videos looks exquisite on the Tab anyway.
Resize your video to 1280x720 by clicking on the Picture tab on a Windows machine. Mac users can click the Picture button to change the resolution. Leave all other options intact!
5. Hit convert and wait.
The resulting file will be less than 1GB for a 1h40min video! You can push it with ADB or copy it through MTP without reconversion!
On stock ROM and with Galaxy Task, I've been able to play 720p with no lag using diceplayer with the Tegra2 add-on. No overclocking. I think it's going to depend a lot on how the file was encoded, though. It just happens that I have no problem with the videos I play.
yeah i've been playin with .mkv files on my day old stock rom (but rooted) tab...
my experiences...
transferring 720p mkv via std mtp mount on win7 pc = file copies fine,
1080p mkv wont transfer (it copies for an 1hr, gets to 5 secs to go & fails lol)
stock player can't play mkv for shjt
mx is laggy as hell & hw decoder doesnt work
vplayer does a good enough job with 720p, when using a buffer & hw decoding
i realise there's a lot more to a movie file than its extension... but that's all i realise ;-)
did kinda expect better from the tab tbh... my old cheapa$$ arnova a9 g2 (that i took back to the store & put money too, to get the tab) could play 720p on the stock player.... (exact same files i'm testing on the tab)
i might check out diceplayer that y'all raving about or even BSplayer, my preferred mkv player on my laptop
