are there any Video Playback Fix for Kitkat based roms ? - Samsung Galaxy Nexus

already tried several different kitkat roms for gnex maguro ( even tried those based on CM11 )
all of them had problem playing mp4/mkv files smoothly when hardware acceleration is enabled
software acceleration works ok.... but my units easily runs hot and runs of out battery
already tried MXplay , Dice at Bsplayer

[MOD] [720p HW PLAYBACK] libOmxVdec.so (removal of h/w restrictions in playback)

best 720p solution yet.
Just want to inform all desire owners of Diceplayer.
It dosent support our phone (they say).
But it works flawless if you patch
libOmxVdec.so
wich is meant for the nexus-1.
Since N1 and desire share alot hardware i figured it might also work for our desire.
IT DID!!
This is my first thread or even post on xda.

What Rom Does it Work on?
GB/FROYO - Sense/Non-sense?
Apparently what it does is, it removes restrictions in the h/w decoding. I think the devs of cyanogenmod should look into this and integrate it into their libs.

I use it with cyanogenmod. So yes. Not sure with other roms but i suspect the libs are the same with sense roms.
The modified lib brings h/w hd functionality to other players aswell. Free alternatives like qqplayer. Probably other players also.
Someone should hint the devs of cyanogen to integrate the functionality into their roms. Devices that are capable. The Nexus-1 and desire.
Just tested it on Rcmix 2.0 sense rom still lags
So basically it will work on GingerVillain 2.7, too? Well, I'll try and see.
Playback yes iirc, but isn't 720p recording Sense only feature?

You must use a player that uses hardware rendering. Default setting in many players are software rendering. Change to hardware rendering (in player).
it worked, but messed up the weather vids on cool sensation though.
hi to all,
just tried the patch and i would dare to correct the OP, well at least in my situation, 720p video playback didnt become without lag, however, now its less laggy. im using GB rom, Rcmix 2.0 with CM7r2 partition table, and class 10 16GB micro sd card (reading writing 11mb/s, reading 22 mb/s). so it has nothing to do with the card, however, as i said there much less lag now but videos are still not as smooth as i used to have on 2.2 based ROMS. but if htc release proper GB rom then maybe developers will be able to do something about it

You should write, which rom/kernel you are using. Otherwise your information is very senseless.

Well. I am using cyanogen kernel and nightly rom. I have a class 10 sd card (sd-booster 2048).
I am having good results with 720 mkv video (diceplayer and qqplayer).
it works..!
took quite awhile for me to get SDK adb working.. but now it works so smooth!!
either on dice player or native player!
kudos for TS
PS: im also on CM7 rom and kernel, S2E a2sd, and stock 2GB SD card
work on leedroidhd?!
Would it work on Insertcoin stock GB rom?
Sent from my HTC Desire using XDA App
no idea of other roms aside from CM7, but i suggest to do nandroid backup, and then follow instruction inside the link from 1st post..
@OP - Are you part of dev team for this? I ask because you seem very keen to get this integrated into CM and you seem to have a lot of technical info.
BTW, I tried it on CM7.1RC1 and find lag. The "News & Tips" page you linked to does actually state though that 720p does lag at present until possibly the next update.

If you manage to load the lib correctly (works in cm7, thats all i know) you should feel big difference from regular software encoding players like rockplayer etc.
Shure. there are some lags. But as i stated before. noting in comparison to software enc. based players. Very large 720 mkv may lag. But a typical 4gig 720p mkv plays well.
No. Im not in the dev team. I just been searching for a solution to play hi def mkv video. And this is by far the best solution.
What i do is every time i reflash my rom (cm nightly) i replaces the lib from first post with the one included in cm7 .zip file. /system/lib/libomxvdec.so
For testing this you must make sure diceplayer or any other player, is set to hardware encoding. Otherwise no improvement in playback.

[Q] Hardware video acceleration in 4.3

I want someone that had purity rom(4.3) or a CM10.2(the newest nightly) to confirm that the hardware acceleration is fixed and back to track,
same as it was with 4.2.2 because i had cm10.2 a long time ago probably the 3rd nightly when it just came out and i noticed videos lag
like hell(bsplayer/mx/dice) so please someone confirm that it was fixed on purity or newest cm10.2 nightly because i don't wanna waste my
time installing them and finding out that its not fixed again then roll back to cm10.1.... its annoying as hell.
//P.S Don't confirm for videos under 4 gb, i need a 4gb+ mkv file 720/1080p because that's when you really need the acceleration.
Vanir is doing it as well (4.3).

Well, i just installed the latest Vanir nightly, then installed MX Player and the v7 NEON coded, did a h/w+ test, and it lagged
I tried the same .mkv file with the same player/settings on 4.2.2 cm10.1 and it played smoothly, I tried purity rom, same thing
Tried even cm10.2 nightlies, same thing. I guess we're doomed.
Loaded stock 4.2.1 as of right now and working flawless.
sent from my GNex
So still no ideas why HW video decoding is F*%$ed up in 4.3?
Anyone running 4.3 stock, factory image from Google, do you experience any issues with HW video decoding? I'm wondering if the issue is specific to AOSP compiled ROMs.
What is the best way to get Google's attention and help with this?
I think you can post a bug, but I can't remember where it is.

1080p Playback on Beanstalk 4.4.278

My Acro S is running Beanstalk 4.4.278. Great rom so far but 1080p playback (specifically on MX Player) does not work. Freezes and reboots my phone when I try. 1080p recording with latest Google Camera works like a charm but its frustrating I can't view any of them. I haven't tried playback on any other video players though. I removed the video player that came with KitKat or the rom btw so I can't try that too.
Any help or advice?

Just tried it (since I had never tried it before you mentioned it) and it works fine. The video is a little juttery, but I can live with that.
Running BeanStalk v4.4.285, on the same phone.. Kernel is 3.4.0-Evovle-v1.11+ [email protected]
I think you might want to upgrade to the latest version - that might fix it.

Thanks for answering
Any notable bugs on 4.4.285? I might upgrade if that will fix the playback problem and if there aren't any annoying bugs..

There are two that are a bit annoying (again, not everyone has these though, so you might get lucky).
1. Sometimes when a call comes in, the screen will either stay blank and take a while to light up (by which time the caller has hang up)
2. Sometimes streaming a video online (with any player, not just MX) will crash and force the device to reboot when you try to exit watching the video.
These are the two major issues that I find on my phone. Never the less, I still prefer this version to stock, so I have been using it for more than a month now and I am very happy.

[Solved] h.265 decoding with hardware

Hi all,
I seems to have a little problem when it comes to reading h.265 encoded files. I'm on MX Player and while the software decoder works (but with stutters on the image, except for very low size files) the hardware decoding option gives me a black image at all times. I don't understand why i can't seem to decode h.265 since qualcomm affirms that snapdragon is able to decode it.
Any idea where this is coming from ?
I'm on stock LP rom with the last update.
Thank you
djona12
Try a different player - BS Player for example (or VLC Player).
Tried a whole bunch of player but none is working unfortunatly
All failed too decode smoothly with software (either video lagging and getting out of sync with audio or partialy grey image). Our 801 isn't powerful enough to decode h.265 with some software...
What i don't get is why no player seems to be able to use hardware support to decode the video since qualcomm said that we got h.265 support Could it be rom related ?

Well, I'm on OmniROM and have the exact same behaviour...

That doesn't sound good
I also tried to change the screen resolution (to FHD and HD) while playing a video but same issue, i get the sound but no image in hardware mode...
I'm starting to think that h.265 support from the snapdragon 801 isn't real :/
Update!
I'm actually running a test drive on the SlimSaber LP ROM, and I'm totally able to smoothly play HEVC /h265 files using MX Player and the HW decoder.... :victory:
However, it complains that the HW+ decoder isn't supported.
That's some good news
Gonna give it a try, thanks for the update
About, HW+ decoder, i can't get it to work on any of my devices... Doesn't really matter when we already have HW i guess^^
EDIT : Little update here ! Tried SlimSaber to see about the hw decoding support (thax to AngryHapposai), worked fine, then went back to Color OS and hw decodinf was still supported ! Problem was the kernel on stock wasn't able to give us hw but the kernel from slimsaber (Linux 3.4.x) was... Restore with TWRP didn't reset kernel and after 3 days of use everything seems to work like a charm, hardware decoding included !
