Diceplayer supports Galaxy nexus - plays MKV/AVI with Full HW acceleration

Diceplayer v 1.7.4 supports Galaxy Nexus.
It take advantage of OMAP4's video decoder.
720p H.264 High profile + DTS/AC3/Flac audio MKV with embedded subtitles works perfectly.
I'll post some test video on next Monday.

YES. YES. YES. That is awesome. My only reservation about the phone was codec support. Thanks for sharing Juami!

Awesome try some 1080p stuff. Also try mxplayer if you have the time

I think devs could not get Galaxy Nexus yet.
I got unreleased Galaxy Nexus for testing. so I could release diceplayer update for Galaxy Nexus.

Thanks for the update, been using Diceplayer on my tab 10.1 for a while now and it's been awesome. On the nexus however it seems it's missing some frame rates. Will try it with a few more vids and see how it goes.
Edit: Tried a 720p mkv and it was flawless. Avi's of TV shows are playing back at a low frame rate, and are noticeably choppy.

I can play 10gb 1080p rips without problem, Can't try anything larger as Diceplayer crashes when I try to play over my network so have only been able to play local files.

Plays local files fine but doesn't go fullscreen - leaves the onscreen buttons.

VPlayer seems to work nicely

The UI for Vplayer is defo not perfect.. the folders glitch, and the soft buttons stay lit, however the playback is smooth and in sync, so very usable for now.

vPlayer have a good sw video decoder(ffmpeg) but
vPlayer can't use HW video decoder except native supported format(mp4).
SW video decoder use higher CPU power than HW decoder and drains battery too fast. and loose a color detail.

Great news. Loved the Dice player on my Asus Transformer. Sold my tablet though so I'm looking forward to using it on the GN

Has anyone tried playing MKV's on the native ICS media player? I can play aac-audio h.264-video MKVs without installing any additional player

after Honeycomb, Android supports MKV format ( not perfectly) but audio codec limited to AAC/MP3.
if you want to play AC3/DTS/Flac audio and embedded subtitles, you should install 3rd party player.

Just though id add my findings.
Ive tried dice player but as with Vplayer i have had mixed results.
Some of my Mp4 files play just fine whilst others fail to open. The player just goes back to the andriod home screen. The ones that fail have ac3 audio.
Im guessing its down to the audio codecs required to play the files.
I do like the look and feel of the app though.
Its a shame im having these issues as the galaxy s2 played them all natively.

Haven't bought Dice Player but I can confirm the trial will playback high profile MKVs in 1080p:

I tried Diceplayer on few local 720p MKV and these play nice.
But two things:
1. My TXT subtitles did not load.
2. When I tried to play the same file from network share, Diceplayer crashes.

I was just able to mount my network share drive via CIFS, so that it appears under /mnt/cifs/share
Then I tried Diceplayer and it did play my 720p MKV in HW with no delay on start.
If it only supported TXT subtitles... (it would probably need to handle different formats, as I have noticed sometimes different formats used in TXT file)

Will run my usual batch of test video files through the Nexus and Dice Player in next couple of days as I just got my Nexus. Expect it won't measure up to the Note/SGSII that I'm accustomed to, but if it can handle 720p I'll be happy enough...

Not sure If I posted this already, but Dice player was able to play 1080p mov trailer in hardware other players either could not play at all or used software and were skipping.

FullHD videos and custom ROMs

Hi,
I was just curious as to why the Full HD 1080p videos (for e.g. H.264 trailers from Apple) refuse to play smoothly on any CM9 and CM10 custom ROMs (with Moboplayer, Acer Media), while the same videos play buttery smooth with the same players on the official stock ROM? Do I need to tweak any settings or install any add ons in the custom ROMs to enable such playback. I am assuming that it is a hardware-acceleration issue because the setting for software decoding in Moboplayer has been turned off. However, 720p videos play fine.
Thanks.

Never had this issue, 1080 plays fine for me. Is this over HDMI or doesn't matter, just always? I use dice player and occasionally mx player, both play OK for me.
Some are encoded differently then others so some may need a bump up in CPU frequency but most generally play fine at 1ghz with deadline. Of course this is my device with my movies on my build, any number of things vary between the files and roms and players used.

OMG Thanks.. DicePlayer works like a charm. :good: :good: :laugh: The files I use for standard video play testing are Apple Movie Trailers 1080p H.264 / AAC 6 channel MOV files.
Now I am observing a very interesting development in the latest CM10 preview. Acer Media and Acer Video Player won't even detect the MOV video files. MoboPlayer and MxPlayer detects the videos but shows laggy playback on the device screen as well as over HDMI.
Only DicePlayer plays them like a charm, without hiccups or lags and going to be the only player I will ever use from now on. I think the issue is probably some proprietary codec related because when I am on the official ICS ROM, all these players detect and play those same MOV files smoothly both on-screen as well as over HDMI ..

Glad it works for you, it seems to "force" hw decode more reliably then other players so far and seems almost infinite in what it will play. MX in fast software fills in where dice fails for me, which is rare. MX seems to handle web streams better though.

Best videoplayer app?

I used to use diceplayer, it was my favorite and it played almost everything with HW support, but since I installed CM10 Jelly Bean on my glide, it just cannot play some of my videos (especially 60fps or HD videos). (Yea, I downloaded the tegra 2 plugin, too).
I also tried mx player with its arm v7 plugin, and so far it is the best for jellybean, however, HW accelleration doesnt always work with it either, but SW decoding seems fine.. Why does video playing suck on jellybean? on ICS it was perfect :\
is it the players (they simply dont support HW that much, they're not updated well?), or is it jellybean itself?
What videoplayer have you found as "best working" on JB?

MX player. I am on android 4.2
Simply the best player.

i use VPlayer. seems to have all the proper codecs i need to play any and all video format i throw at it, including mkv files.
however, there is some fine tuning you must do to correct the video/audio sync issues when it plays mkv files.
i have the unlocked version which i bought when it was on sale via the google play store.

No problem on hardware acceleration in CyanogenMod 10 Beta 2. I have some HD video in the phone and it plays them fine, whilst Android 4.0 refuses to do very much in frame sync. Jelly Beans is much better, IMHO. I have no trouble with MX player on this firmware.

Mx player codec?

Hi guys, in play store I found 2 or more codec packs written for arm v 7, arm v 6 like that.. which one should we install for one x?
Cool....)

MX Player didn't ask me and I didn't installed any codec. It works fine. On MX Player's Google Play page, says:
MX Player will test your device and show you the best matching codec automatically if it is necessary. You do not need to install codecs unless MX Player asks.

MX Player comes with the ARMv7 NEON codec built in which is the one our phone needs. The rest are for other phones.

Have u tried playing vob mkv files? N I had slow playing of videos with h/w decoder n with high resolution videos, thought tht codec was the problem...

Stream HD TV from FreeBox
Hello All!
Mx Player is a good product, thx.
But i can't get any sound when streaming a HD TV from my FreeBox (Internet and TV supplier).
I did install ARMv7 NEON codec but nothing better. tried too to use S/W decoder for audio, but no.
video is good but no audio.
how could i solve this?
Google video reader has not the audio too, VLC has the sound (but video has lags)
do i have to install other codecs or is my tablet CPU power too low?
Android 4.1.1 JellyBean ARMv7 Processor rev 0 (v7l) JRO03C.v003 -> 1512.0MHz double core
Stream format : video MPEG-4 / audio AAC.
thx,
Alain (from FRANCE)

Hello. H/w does not play every video, cos h/w is the same with stock player. When I turn on program decoder I can watch every video I want; actually in any format. I haven't downloaded any codecs, I just installed the app. Notice that I use old version of MX player, I don't update it cos I have heard that there're issues in new versions.

HW video acceleration problem with 4.3

Hi,
I've noticed that since android 4.3 something changed in terms of hardware video acceleration.
I used to watch movies on my Galaxy Nexus and the same movies that played nicely with 4.2.2, now stutter or lag with 4.3
I've tried with the latest MX Player and BS Player and even the internal stock video player. All do the same.
I used to play HD 720p videos and some 1080p videos without a single glitch, as long as HW or HW+ (MX Player) were enabled.
Now, after a few reencodes and tests I've come to the conclusion that the reference frames can't be higher than 5. An AVC video with ref frames of 6 and higher play with stuttering, but when in SW mode, they play OK.
You may download the samples to test:
H.264 HD 720p [email protected] ref frames 5
H.264 HD 720p [email protected] ref frames 6
Ref frames= 5 plays like it should, no problems with HW acceleration
Ref frames= 6 stutters, lags. Only plays nice with SW mode.
I've tried with a Galaxy Nexus of a friend, also with 4.3 and it happens as described.
Anyone would know why would Google break the acceleration, or how can I report this?
Thanks
Nuno

Hi, I just registered because I have the same problem. I even searched and tried a lot of apps and it doesn't matter, the result is always the same. My GNex plays some files very choppy.
I downloaded both videos you linked and tested with MX Player (with custom codec ARMv7 NEON)
Ref. frames 5 = Plays fine with HW+ and SW.
Ref. frames 6 = Plays choppy with HW+ and plays fine with SW.
I have a lot of playback problems with most video files, specially TV series rip from the scene (for example HDTV 720p rips from DIMENSION and other scenes group) and some other 720p BluRay releases and it stutters like hell in HW+. Some times HW it doesn't even work and with SW plays fine 10 or 20 seconds and then starts to stutter a lot to the point it is unwatchable.
Then if I test some 1080p movies (even 15gb files and over LAN) they play excellent. Some don't.
I tried everything, even forcing min. CPU freq. for MX Player with Franco Kernel and it's always the same.
I have Android 4.3 (clean install) and I tried with and without Franco Kernel and it doesn't matter.

You have to understand 4.3 API is not easy. It's been almost a month since the release of 4.3 and there hasn't been a stable ROM, kernel yet. If that doesn't drop some enlightenment then you have to realize 4.2.2 took 8 months to perfect and reach where it is. Rather than blaming 4.3 how about you understand the coding that goes on behind it. The app developers never meant to focus solely on 4.3 they need to make sure that it doesn't cause instability for 4.2 and below, as there are tons of devices from different oem that react differently to small changes. Just be patient and the dev will sort it out. Quit making like little girls 'daddy I want it NOW NOW'. Be patient and eventually it will be fixed.

Misledz, nobody's whining.
Both me and AgusL just pointed something that I haven't found discussed anywhere else.
The purpose of this thread is just to share one's experiences with this subject. I perfectly understand this is either a bug or a intended feature of 4.3. I just hope it's a bug because I'm used to watch a lot of movies on my GN and now they are unwatchable (battery-wise)
Would you be so kind to share your experience with your Nexus 4? Does it affect it also? I am just trying to figure out if this is PowerVR SGX540 related or if the Adreno 320 is also affected.
Thanks
Nuno

Using the Android Video Player and MX Player, I have no stuttering or lag on either of these 2 videos.
I have used MX Player and switched between HW and SW decoding and cannot see any issues.

on CM10.2 (unofficial) playing HQ/HD videos though MX by using HW or HW+ decoder.. makes videos laggy..
SW works perfectly..

I wish that people who discuss possible bugs and problems would firstly install Google stock Nexus image and test there, before flashing incomplete nightly ROM's and judge how the new system is.
FFS.

No problem playing videos with latest MX player pro on stock 4.3 here, I think the problem is probably rom related if using a custom 4.3 rom.

Factory resetted Galaxy Nexus with OTA updated 4.3 firmware, and then reflashed to stock 4.3 firmware, and another GN OTA updated to stock 4.3, both displays severe glitches in hardware video decoding mode. Tested in the Dice Player and VLC Player with HW decoding enabled.
Video track info from the problem files:
Format/Info : Advanced Video Codec
Format profile : [email protected]
Format settings, CABAC : Yes
Format settings, ReFrames : 8 frames
Format/Info : Advanced Video Codec
Format profile : [email protected]
Format settings, CABAC : Yes
Format settings, ReFrames : 6 frames
On the Nexus 10 and the Nexus 7 (1st gen) both with stock OTA updated 4.3 firmware exactly the same files played well in HW decoding mode.
Only Galaxy Nexus seems to be affected.
On the stock 4.2.2 firmware and CM 10.1.2 problem does not exist.

My apologies I didn't mean to make it sound like it's whining. I just see so many posts saying 4.3 is bad in the general section that they just get shut down. Perhaps we got off on the wrong foot, what I meant from experience was the 4.3 API just has a few restrictions unlike the open breeze the previous builds had. People and paranoia just request so many things that what's not broken ends up being broken due to changes. I felt it was unfair if I had not shared the experience.
On the GNexus and N4 I don't have that issue. I assume this was supposed to be kernel related since we are playing with builds that weren't supposed to be released for us. I've tried downloading a 1080p MKV file (I am Legend) and streamed it off an SMB server, and it played flawlessly on DicePlayer (GNexus) I had no stutter, subtitles loaded perfectly and I still got to see Will Smith fire some rounds in the air.
Have you given DicePlayer a go? I promise it's something not to look back upon

You see, not all files have this glitches. There is a problem only with specific video coding, I.e. ref.frames=6 or 8.
Do you tried examples from Nuno_PT post?
Just tried examples from top post and "ref frames 6" definitely have problems with Dice Player v.2.0.35, but "ref frames 5" playing well.
Latest MX Player Free not playing "ref frames 6" in HW mode, but does fall-back to software decoding (and displays HW mode icon simultaneously - that is bug, obviously) and playng in software, with corresponding CPU load and battery drain.
Galaxy Nexus with stock 4.3 firmware.
Youtube videos playing perfectly.
Video files with ref frames = 1, or 2, or 3 - all playing well.
Trailer "Prince of Persia - Sands of Time" in 1080p for example, have video track:
Format : AVC
Format/Info : Advanced Video Codec
Format profile : [email protected]
Format settings, CABAC : No
Format settings, ReFrames : 2 frames
Codec ID : avc1
And, of course, playing well.
But video files with ReFrames = 6 or 8 definitely not playing well in HW mode on stock GN 4.3.
SW playback does too much battery drain, so it is a problem.

First I would like to say that I am glad this is not a problem with only my phone. It pleases me to know that affects all Galaxy Nexus with stock 4.3, and it looks like CM 10.2 is also affected.
I came to the conclusion, along with Vinni Sanders, that this only affects HD encodes with ref frames higher than 6.
Most scene movies you find over the internet where encoded with 12 ref frames, or at least higher than 6.
The thing is that with stock 4.2.2 this didn't happen and I could play videos with 12 ref frames with HW acceleration, as far as I can remember.
At first I didn't know what was the trigger, but after messing around with re-encodings of movies I came to the conclusion that it were the ref frames.
I haven't made tests with 1080p, so I can't state how many ref. frames would trigger the stuttering with HW acceleration. But I do remember watching high bit rate 1080p movies with HW acceleration when I had stock 4.2.2
My question is, what's the next step? It surely looks like a regression. How can we correctly report this to Google?

Nexus 7 -> MX Player on H/W+ plays perfect, no frame drops at all.
Galaxy Nexus -> MX Player on H/W+ very laggy. H/W is the same. S/W plays perfect.
Also, some 1080p movies play fine on my Nexus 7, but on my Galaxy Nexus will only play (laggy) on S/W mode only. H/W and H/W+ gives me an decoding error.
So, the problem is Android on this particular device, and not an Android global bug across all devices.
Is there a way to test at what percent the GPU is used when playing a file on Android? I tried through Developer options, but some of you can do more serious tests.
Please forgive about my english writing

Got the exact same issue with my Galaxy Nexus stock 4.3. Alle players have major stutter when using differnt mkv files. Same codes as described below. Alle scene stuff from the interwebs.
There is the official issue tracker for Android: code.google.com/p/android/issues/list

Same issue for me with cm-10.2-20130815-NIGHTLY-maguro.
Technical Support from MX Player says:
You are all right. Hardware video playback is broken on Galaxy Nexus 4.3.
Unfortunately it cannot be fixed with HW+ decoder because it is a kernel side issue.
I'm not sure who made this issue but may be one of these: Google, Samsung or TI.

Hi guys,
I am having the same problem with my Galaxy Nexus and 4.3. Videos with HW Accelaration stutter like hell, unfortunately the Software Decoder is not completely smooth, so that is not an option for me. In addition to the video issue, my phone felt much slower than before.
I downgraded to 4.2.2 yesterday and I am very happy with the fact, that the phone runs so much smoother now and I can watch videos again. I don't see any reason right now why I should upgrade to 4.3 soon. Maybe to 4.3.1 when Google fixed these problems.
I can recommend anyone to go back to 4.2.2 again. The phone is wiped, that is true. But it also runs much better than before. It will cost you some hours fixing everything back up, but I don't regret it.
Cheers,
DS

I was able to reproduce OP's issue on stock 4.3 with MX Player.
Very odd. Fortunately I use my Nexus 7 to watch tv/dvd/br rips so I hopefully won't really run in to this issue during my regular use, but it is definitely there.
