[Q] cant play some mkv's - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hey there,
I mainly use my tab for videos and ebooks, and i faced problems in running some mkv's.
basically i was trying to play an anime video by coal girls but the player did not play it.
These are 720p videos with flac audio.
Also happens with videos by re-packers like horrible subs and gotwoot...
I know that the tab can play 720p mkv's watched a lot of 720p movies on it flawlessly. But then why does it fail to run these.
P.S. : I also tried mxplayer but it plays the video on s/w decoder and that too very poorly even after enabling multi core decoding for s/w decoder.
Thanks in advance.

cant play 10 bit video's as well
well i tried playing some more videos, could'nt play 10 bit-720p-BD-AAC video's as well.. :crying:
Tried a lot of players, default samsung can't play it and players like mx and dice default to s/w which stutters so much that the video is unwatchable ...
I was hoping that someone had experienced it before and tried a custom ffmpeg i.e custom codecs to solve the problem.

Did you tried h/w+ mode in MX player?

Yup tried that, didn't work
yup i tried that even allowed the 10 bit video option, the video which i have uploaded just won't play on h/w or h/w+........
Can't see any other option now.Why don't you try to play the video i have uploaded...
If you want the details :

plays fine on nexus 7
I played the same video on friend's nexus 7 and s2 which plays it pretty well on s/w decoder, however the tab 2 lags like hell in s/w decoder.....
Don't know what to do now...
Can anyone try the video sample i uploaded in post 3 and post the results....

Or you can use splashtop 2 (free on market) to stream the video to the tab... Works perfectly for those who don't want to convert tons of videos...
Final conclusion : There seems to be a problem with the native h/w rendering capabilities...so no software can help it..
720p mkv + flac audio or 10 bit 720p videos are not playable natively mostly due to the poor gpu, and poor performance with s/w decoders.

I use BS player. It plays everything, using H/W decoder. Plays local, or off the network.
Use the ARMv7 version, and also download the BS hardware decoder, it is vastly improved over the stock or AOSP one.

Tried it but fails to work in h/w

Installed bs player free + arm v7 vfp cpu from market, but it still plays the video using s/w decoder with terrible frame rates. Frame dropping option also dosen't help. And when i choose h264 hi10 to be played on h/w decoder , there is black screen with only audio.
Try the sample which i have uploaded in post 3 and post the results. I'm on stock rom so maybe cm/aosp plays it better. If so i may install a custom rom..

not possible to play 10 bit videos at the moment
So i finally dug around the forums myself and realized that there is no android device that can play 10 bit encoded videos at the moment, not even tegra 3.......
source : http://forum.xda-developers.com/showthread.php?t=1425664
At the moment, 10 bit encoding i fairly new and requires much more power than ur 8 bit mkv's which were used to have earlier.
So basically our tab can play 8 bit 1080p videos flawlessly, but fails to do so for a 10 bit 720p video on h/w decoding i.e ur stock samsung player will refuse to play it and all the players that u will try will play it on s/w decoder no matter what u try and yet u'll get very bad frame rates.
SO the solution is to :
1) re encode the videos, which did'nt work for me cuz i lose the subtitles while converting(some error)
2) can stream using splashtop2 ( free in play store) which is okay but need to have very high net speeds..... :/
If u cant play ur vid's properly, first see the details if they are 10 bit or hi10p if yes try the above.
Cheers

From what I have tried dice player runs 1080p .mp4 files pretty fine.
But it seems you are trying to play very high bit rate 1080p .mkv/.mp4 files which I guess gets a bit too much for R / most other smart phones to play.
If the above is true then you'll have to convert those videos to a lower bit rate format.
Hope it helps.
But those videos were running on my friends sgs2 properly without Any third party apps
And I have read that sgr supports
Full he playback and now the native player is not able to do so.

becoz our tegra supports 1080 p video playing capabilities.... (as we can play in optimus 2x but only 24 fps)
butt somehow samsung has blocked some of the capabilities of sgr
1080p playback?
So in short we can't play 1080p videos on our SG-R?

We can play them buddy . . . !
I have played some good quality 1080p MP4 videos on my device. Its just that it shouldn't be a very high bitrate. I have yet to try any mkv files though, will try & update here.
Tegra 2 naively supports recording of 1080p videos which had been disabled by Samsung due to some reasons currently not clear.
But they can't block a device which naively supports recording 1080p videos from playing Full HD videos as it depends on which video player you use.
The generic Samsung player doesn't play 1080p videos but Dice player does and its currently free.
Hope this helped.

[Q] Can galaxy r play this video?

i think galaxy r has a weak DSP because it records 720p video and doesn't play 1080p videos and i think even 720p playback is limited to [email protected]/4 ref frames.
here is a 720p mp4 avc [email protected] sample for you to try and see if it works in stock player:
https://rapidshare.com/files/1822600111/720p_avc_high_l4_cabac_4_ref_frames.mp4

the samples are only 2 mb, so please try them out in stock player and tell me the result.
thanx in advance
1) Why do you have to use a stock player if you can choose full HW-accelerated: Dice or MX player?
2)I have S2 - I can't really see the difference between 720p and 1080p on such small screen (4'3") and I don't think any human eye would see it

stock player also does hw acceleration, and if a dual core phone doesnt play 1080p video, then at least it should have full 720p support
yes but stock player doesn't play all video formats the two players above do.
BTW. these samples are far away from HQ-quality, especially divine enrique is extremely pixelated I don't think it'll make any difficulty for SGR, but let's wait and see.

stock player doesnt play all formats because it does hw decoding only while mx and dice can do both hw and sw decoding which uses cpu and drains battery much faster than hw
and it is not about quality(bit rate), what matters is resolution(720p) and codec settings([email protected] frames)
I tried to play these 2 videos..
stock player was unable to play both the videos..
but. mx player with fast sw decoding played both clips very well...

Hey i tried using vplayer to play a video, its still lags.....
The video is a dvd rip movie and a mkx format (i guess, though not sure abt the format) and apprx 1.7GB. When i tried playing through stock app, it didnt played.
When i tried using mx and dice, they played but a bit laggy.
but when i used xplayer, its more laggy
and upon using hardware decoder in mx,dice its unable to play
is there any solution play such video without any lag on our R ??

this phone doesn't play anything in stock player(hardware decoding) above 720p [email protected]/3 ref frames, you can download media info to know the specs of the videos you want to play:
http://mediainfo.sourceforge.net/en/Download
i guess if you want play anything above that smoothly using CPU( software decoding), you should use NEON optimized codecs for the player you installed like mx neon codecs from here:
https://play.google.com/store/apps/details?id=com.mxtech.ffmpeg.v7_neon&feature=more_from_developer
but, you should install mx player first

[Q] .mp4 video playback problem

I watch alot movies on my phone and when a movie is .avi format no matter how big (1,2gb) is playing with no problem, BUT when its .mp4 on the stock and some other players says, sorry this video can not be played, and on some players like mobo or mx (the ones with codecs) plays but with lag (the picture is like a slow motion)?
Its funny cos the videos that are recorded with the phone are .mp4 and are played very well...

Most likely your mp4 file has H264 video with a profile above what this device supports in hardware... For that reason i would like a dump of the technical details of the file. On windows if you use MPC-HC there is a properties windows with a mediainfo tab.
AVI or MP4 are only the container format that encompasses varius audio, video, subtitles tracks. The video codec inside the track is what matters. Most AVI files contain one track of video and one track of audio, but the codecs usually are XVID and MP3. In the case of MP4 files the codecs are H264 and AAC. But H264 has a enormous range of profiles and levels that increase the CPU power needed for a given bitrate.
http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Profiles
IIRC, this device only supports H264 baseline profile in its hardware decoder, so if your file has a higher profile using MXplayer it will decode in software.

[Q] Soft-subbed mkv video playback problem

Hello fellow GNOTE 10.1 users,
Idk if anyone else tried it but when I try to play some soft subbed 720p videos (mostly anime videos with eng subtitles) the stock media player could only play audio and the best I can have some laggy playback using BsPlayer free. So, does anyone know a way to solve this problem? Is it a much broader problem in Android devices in general that has not been soIved yet or does some certain magical codec pack do the trick?

Try both hw/sw /hw + acceleration. If it doesn't work. Then the last chance is in dice player those are the best 3 players in market, but don't worry it is definitely not the device's problem it is software issue
Sent from my X10S using xda app-developers app
Tried both. in hw it does not even show the video and in sw the problems I've pointed out persists. I've tried many different players before -dice as well and it was BsPlayer which gave the best performance. Though as I said, it is also laggy.
Thanks for your time and suggestions.
Yeah, I have the same problem. Looks like I will have to extract all the subs....no other player worked....
Edit: I tried another animes from other sub groups and some of them are working, like from gg and gotspeed, no luck with coomie and utw though, I gotta look at it, maybe theres problem with the format of the subs.
Guys, after the long struggle, I found the remedy! Just install archos video player and its codec pack and that's it. 10-bit video playback problem is gone forever.

if you want you can root and use scripts like thunderbolt to boost your phone's performance.
h/w+ codec doesn't work for all videos. so its no use thinking about it.

In gallary of galaxy s duos it should run 720p video of avi and mp4 smootly but the other for the format we need to install player
But u have installed the mx player it should had detected video format to run smooth
Try different player like Bsplayer or go to setting of Mx player and switch to s/w decoder for all the video It should work

i have tried every thing but nothing is helping me out...
it works
changing the decoder from hardware to software in mx player did work! Really!
1080p runs like a charm, at naturally smooth frame rate.
answer is simple, graphics hardware in s dous is not capable of handling the video on its own and with full hardware acceleration. point of shame, though, ace 2 can even record camera at 1080p. on the other hand, processor is good enough.
my guess is, class of sd card also matters. there may be other apps using the card and for mx player, it only gives a fraction of the full read speed which makes the frame rate look bad.
I used class 10 scan disk, 16 gigs and s/w encoder in mx player, it runs as smooth as the screen can bear. not as robust as my galaxy s2 does. but it goes to the better screen quality, instead..
