Is there a way to properly play this type of videos on Android, furthermore our Nexus 7? The video is 1.7GB heavy, when playing in MX Player, it lags, VPlayer crashes, VLC lags as well. I'm thinking it may be too heavy. Is there a player, kernel, kernel with OC which could help here?
Thank you!
Btw, to convert it is too much, just so happens my external HDD is full of videos encoded this way. Playing it directly from HDD (mounted with OTG and StickMount) and playing a copy on device's memory gives the same result.

Have you tried Diceplayer with the tegra 2 plugin?
Free from Google Play.
I have had it running a few decent sized mkv's and avi's with no problem, and at the end of the day its a free app so nowt lost in trying it.
I just download videos (multiple formats) 720p/1080p and play it via mxplayer over wifi or usb otg and have yet to find a clip that didnt work. I download movies from torrent so most of them are properly ripped with decent bitrates.
Please ignore my spelling mistakes. English is not my native language.
Did you activate hw +

Try Archos Video Player with all plugins installed.
if VLC doesn't do it then I'd try diceplayer with the proper plugins...
I seem to have forgotten turning HW+ on. It's working flawlessly! Thanks!

Just updated to the new MX Video player.
My MKV's plays without issue, smother than Diceplayer!
Yes works much batter then dice. Just tested 720P mkv, plays smooth in hw mode with subs.

no HW acceleration for me.
Me either.. Its abit choppy - SW decoder fast mode works best for me plays nice and smooth. Also if its been updated for ICS why do the buttons still remain on screen :|
same here HW doesn't work on 720p video
..couple of days I bought Diceplayer ,avi films works fine but after doesn't work anymore;-(I updated MX player and works amazing ;-)thx
Two things:
1. When I play 720p MKV file locally it plays nicely in HW. But when I play the same file from network share, only software decoder works and subtitle no longer loads.
2. TXT subtitle in the format beow does not display correctly:
1
00:00:00,200 --> 00:00:02,300
/Previously in "xxx"...
2
00:00:02,500 --> 00:00:06,800
Line 1,
Line 2.

send your avi files to diceplayer's dev ( [email protected] )
I'll fix it.
Will be interested to see how my batch of test videos goes on the Nexus with various players... will link to my findings here when I have them!
Yeah, diceplayer works fine with mkv files, but not so well with xvid avis. It is a bit choppy, and ac3 audio plays ahead of video. I bet there will be an update soon enough.

Probably depends on files, all AVIs I have tried played without any problems. But still, most of my files now comes in MKV format.
There is one MKV that no player can handle It's a free sample so it's ok to share: http://www.filesonic.com/file/4051381924/killa.sampla.x264.mkv
After last update, software buttons get hidden in full screen mode, nice.
Any chance for WMV HD hardware decoder support?
K wait so MX Video ... are they still inferior to DicePlayer because it isnt hardware driven? I have read the thread and saw Dice doesnt do well with some formats in some cases but.. I cant decide which to get.. MX Video looks a lot nicer but the DicePlayer market page says it drains less battery and it takes advantage of the Gnex's omap processor for video so.... ehhhh
any thoughts
If MX is said to do everything in software, than why does it show Software OR Hardware decoder option while playing files? Some files get played in Hardware, some in software, all depends on codec. Try both. In my case, subtitles support is important, so most of the time I use MX, but Diceplayer is nice too. Whenever file doesn't play in one, I try the other. Neither is perfect yet.

I have problems with some xvid avi files with MX Player. But even so the decision is easy at the moment because the developer of Dice Player has problems with his checkout account and you can't buy Dice Player at the moment.
Try the free version. AVI's lag for me

Try the free version of MX Player first and see how you like it. MX Player has lag for me in AVI's (standard def) with hardware decoding selected. I have to choose software decode (Fast) for it to play properly.

I have the same problems with xvid avi files, but i can't enable software decode. Regardless of what options i choose in decoder settings, the xvid avi file is always played in HW mode (amazingly an h.264 mkv file is always played on Fast SW mode with the same settings).

Try play this MKV file locally from the phone, not over the network, it should play in Hardware. If it does, then mount your network drives with CIFS Manager and they will play in Hardware too.
How do I access menu?
Hi guys,
Now that mx player hides the soft buttons, how do we access the menu to change the options? I can't seem to find the … button anywhere.

Played it locally, i don't use streaming... the mkv is played smootly in "SW fast" mode, but the xvid avi is not played smoothly in "HW" mode...
I've tried several apps to stream from my DLNA-compliant NAS (Netgear ReadyNAS) and just via network file access (SMB) and all of them seem to have the same issue with video files, it takes forever to begin playback.
The behaviour seems like it could be buffering the entire file prior to playback. eg: a 720p mkv of around 1GB can take about 10mins to begin playback.
Locally stored files have no such issue. I'd store them locally but well, 16GB isn't going to fit many
Thoughts and suggestions?
Have you tried iMediaShare? I'm using the Premium version and don't have any problems streaming from my network hdd.
Man I had a bunch of trouble with lag as well but I've found that mk player in sw mode has no lag for me. I'm using a synology disk station and 264s with great success. Vplayer rock and mobo all let me down with lag or choppy buffering and stuttering frame rates on the nexus with ics. On my thunderbolt vplayer was the winner.

Okay, that seemed to at least partly fix it. MX Player forcing software decode mode works but is a little choppy. I wonder why hardware decoding is causing this issue.
You'll probably have to seek out a player that works well with mkv files on the gnex or switch to something like h.264. I've had better luck using 264s because more of my wireless devices have dlna decoder support for mp4s. That's the one draw back to dlna IMO. Not enough standardization. My direct TV dvrs stream mp2... lol who still uses mp2? Good luck I feel your pain. If you find a good player let me know.

The MKV files I'm trying to play are x264. The MKV is just the container.
I've posted on the mx Player forums to see if they've got any ideas.
Yes, but its the splitters job to get it all out of the mkv and that's most likely the trouble. For kicks try a 264 mp4 and see if your lag vanishes.

Anybody know which the best HW supporting media player is for the One X?
I really like dice player but it won't let me fast forward M2TS files :/
try bs player (my player of choice for hd content) or mx player.
I think alla other players than DICE player makes the HOX get hot .
I watch videos all the time using bs player and it doesn't get hot for me. Long story short though try those apps see which is best for you.
Dice player for me is awful there's loads of my media it doesn't play well (it struggles with the audio tracks mostly).
I think BSplayer is the best one! It plays everything! It even plays in HW-mode through network, which most of the other have serious problems with. And directly from rars too.
However, the only player we know for sure that's using the companion core is the built in one, but maybe power-saving isn't any concern? But with HW-decode on the other players, one should think the load should be low enough for the companion core, but who knows?
yup thats what I found, if you want something that just works with your media bs player is the one. I tried every player going for some of my media and that was the only one that handled the audio tracks properly etc.
I dont think any 3rd party players yet will be optimized for tegra 3 to use the companion core, the stock player does it so thats good it shows it can be done but there are not many devices out there yet with tegra 3 so 3rd party apps havent caught up.
No luck either on all players i've tried with fast forwarding m2ts files
Bs player was one of the best ones I found
However I think i'll stick to Dice player for now, everything seems to play smoothly. Just a shame I can't fast forward/rewind m2ts files
Have you tried Mobo player? It's free and so far has managed everything I have thrown at it...
Sent from my HTC One X using xda premium
Yeah i've tried that as well sadly, it doesn't like my m2ts files either
I'll have to find some way of muxing them to mkv cheers anyway
you could try format factory http://www.formatoz.com/ and I hear good things about video spirt (get the light version for free) http://www.verytools.com/videospirit/index.html

It's bad-ass. I haven't found anything it won't play (oh.... hang on, flv's! - but I don't have any)
+1 for MXPlayer. This app is awesome. Great quality video and support subs.
But what I like the most is that it can play file streamed from PC with very little buffering (depend on video size though). I really enjoy watching without having to transfer tons of files to the phone
Also an MX player user. Would get the pro if it was on sale otherwise happy with the free version.

I used mxplayer for a while but it struggled with Mkv with ac3, and in s/w mode it got hot.
I switched to dice and it not only plays Mkv with ac3 flawlessly but stays cool.

thats basically exactly the issue I keep having with it, loads of my media is MKV and most of it has AC-3 audio which mx player fails at. Sure dice works well for it but so does BS player
Either way there are good options out there, its just a shame that I ended up paying for mx player and vplayer etc only to have to use a free app (bs player) because they dont do as good a job

Hi.. Sorry I may sound noob but I've never knew we can stream videos from pc to HTC one X. Can you please guide me how to do so? And yeah I have MX player, if that is what's required.
Just share your movies as you would share any other folder, open it with a file manager from your phone and play the files (this is technically "streaming" but still you watch your movies without having to transfer them). MX does nice job but some files need to be played in sw mode when played from a network location.

Hi everyone,
Well, i'm very happy of my surface RT, but i have one big problem : read my favourites series on my surface.
At the moment, i use "press play video" and my movies freeze all the time...
I tried to read the same movie from the sd card or from the internal storage, and the result is the same : freeze.
The result is the same with all my mkv.
does anyone have a solution?
thank's
I haven't heard of any MKV player that work with any reliability. VLC player is in the pipeline but looking like vaporware at the moment.
I would suggest conversion or streaming them via Plex or similar that can transcode.

Hmmm, no luck for me. I get the same audio/video sync problems.
What do you use to encode your videos? I use a slightly modified version of the High Profile preset in Handbrake. All the relevant video stuff is unchanged from the preset, which the exception being that I limit the resolution width to 1280. I'm going to try encoding something using the baseline profile just to see what happens.
Since there is still no VLC, i'm using power media player (power dvd).
Streaming 1080p from My NAS Works fine, besides some stuttering at the first few seconds .

The key seems to be the encoding settings. I tried re-encoding one movie using the H.264 baseline profile. The resulting file was about 50% bigger, but plays without any issue. I'd hate to have to use such non-optimized settings, though.
Are you playing back full blu-ray rips (e.g., rips using MakeMKV)? Or, if they're re-encoded, do you know what the encoding settings were? Otherwise I guess I'll just have to play around with some different encoding schemes, adding more H.264 high-profile features until the A/V sync breaks.
Update: Anything about baseline profile gives me audio/video sync problems. That's really disappointing, given that the Tegra3 should have no problem with high-profile content.
Hi all,
I have been trying to stream videos from my laptop to my Note, and I haven't been able to get it running smoothly. I have tried a number of different players, but the issue is that it will either stutter like crazy or play audio without video. I can be more specific about the types of files (mkv, h264, 720p, etc.) and players (VLC for Android beta, Archos Video, MX Player, etc.).
Has ANYONE managed to stream and watch videos from their PC/laptop to this tablet successfully or is this tablet just not capable?
Many thanks!
I am running a plex server on my desktop and stream to several devices, including my note.
Another vote for plex it's pretty amazing. You can get it for free after you get some free coins from the amazon app store.
Of course the tablet is capable of streaming video smoothly. I use MX Player to stream videos from a samba server (traditional Windows share, no special software required). The MX Player is configured to use the 'HW+' decoder. It plays Full HD mkvs no problem.

That's not a good idea as a software decoder will burn through your battery, especially with HD content.
@Junetastic Can you try playing the sample videos from this site http://www.auby.no/files/video_tests/ ?

Once copied to the tablet, it of course played without problems.)

I usually just have to use the software decoder for the Audio. Didn't really know it would take a hit on the battery. How much more will it really take? I have gone through many media players and found this to be the easiest solution.

Oh, I don't think you have to worry about battery life if you software decode just the audio. It's the video that takes a lot of work to decode. From what I seem to remember, software decoding of HD video can drain the battery up to several times faster (depending on brightness and other settings, which can change the relative energy consuption of the decoding process).

I have the P600. I downloaded all of the video clips to my desktop. When I stream them directly using MX player, I do get some lag and stutter. However, when I add them to my Plex library I can play all of them just fine. The Plex server handles all the transcode that is needed and I just have to click play. I don't need to worry about formats or bitrates (unless I want to). It is so simple my 5yo can use it to watch videos on her tablet. She can even sync videos for offline viewing on car trips.

Well, it seems that the hardware decoders are quite different on the Snapdragon vs. Exynos and since Samsung is very sparse with documentation, the MX Player developers didn't manage to optimize their software for the Exynos (this is just my guess). So you might try a different player, perhaps some will work fine. But then again, it might not. In which case you might have to abandon universal streaming and either transcode your videos or use an application that will do it for you on the fly (e.g. Plex as WJThomas proposed). The downside is you have to use a computer (and often a paid app as is the case with Plex) and can't stream your content from a NAS.

The upside is that you don't have to worry about which device supports which formats, and that you can stream content from some NAS's without a computer. If you subscribe to PlexPass the app is free, and you can use the app to sync media to your device (and then you can even stream from device to device)
Can someone please explain how they're playing .mkv files without playback stopping after a few seconds?
What I'm trying to do is play full bit-rate Blu-ray .mkv rips. I am using ES File Explorer to navigate to shared folders on my Windows PC, and what happens is that the video will eventually start playing but then stop after 5 or so seconds of playback and never continue again. I've tried accessing the files via DNLA software like Servio, but I get the exact same result each time.
And bandwidth is not the problem, as I was able to stream uncompressed content just fine when I had my Surface Pro 2.
