Database Develop

Horrible H.264 decoding

I'm not sure that how many people at here know this fact.
Tegra 2's H.264 decoding is waaaay worse than Hummingbird(Galaxy S)
It cannot run any HD H.264 video HP.

Source?
Tegra2 can decode 720p at AVC HP and 1080p at AVC MP with reasonable/usually bitrates at 30p.
€dit: Just seen that u have the korean model, right? AFAIK the LG-Player isn't supporting the mkv-container,
allthough Tegra 2 would be up for the task (at 720p30 HP) as mentioned earlyer.

I think with VLC or RockPlayer you can probably see a difference

How does x264 perform?

I think its the same issue as Adam had with the video/audio desync. Its not a hardware limitation.

I don't get it. I've tried various videos and none of them work properly. However, the demo video files that were on the device (1080p) run perfectly. No frame-skipping at all.
Is there something I'm missing?

I was kind of baffled by this too.
Brilliant playback on the included 1080p files.
So i thought yay lets grab some 1080p trailers from youtube with tubemate.
But alass. not very smooth! Think its indeed the profile that does the trick. or in this case, doesnt.
Next thought. Ok rockplayer will help me out here!.
But i wasnt too impressed with rock on my galaxy s either!.
Loaded rock. but also very crappy. Which is when u think of it, pretty logical.
Why? No hardware support! Rock doesnt even remotely know what a tegra2 soc is. and in fact, NONE of all the video apps do.
So in stead of funky tegra2 hardware decoding, you get software playback.
Ive heard some rumors about nvidia developing an android video player for tegra but i dont know if this is true or not at all.
so unless someone makes a proper video playback app (which in my opinion is way over due already! no offence but theyre all crap if u ask me!) which supports hardware playback AND tegra2 soc, it wont improve very much.
My 2 cents
Ok some more info, apperently Tegra2 isnt very great with high profile encoded. baseline and main profiles should work. more testing to do. Also everything below 1080p high profile should kind of play properly. My eyes are on VLC for android and fingers crossed for them to bring tegra2 suppot and their own great codec sets

Check the Motorola Atrix forum, on XDA (sorry cant link from mobile app), they have basically given up on playing hd h264 files on tegra 2. Such a shame.

Yes indeed. It sucks ass. I have the same unit but then from T-Mobile Netherlands. Video included works like a charm (ofcourse) but own added videos look like they are in slowmotion. 720p, 1080p doesn't mattter same issue.
Extra added flaw? When your record video in Full HD it does not play back on Full HD TV's or BD players. I checked why and found that it actually records in 1920x1088p!!!! Yes 1088P people.
FOTA updates are also not working for the T-Mobile branded unit. Comes back with validation error.

Tegra 2 limitation
Some search on the internet revealed that Tegra 2 supports fully h.264 main profile, but for high profile, it is only 720p 6MB/s, which is then not suitable for a BD. Anyway, I don't have the intention to fill in my 32 GB of storage with just one movie...
Recording in 1088p instead of 1080p is a bit more annoying, you think there could be a solution for that?

Yeah MVK-files can be played with other videoplayers on Market but I've read in reviews that it's awfully "laggy". Saw a video where they tried to play mvk in RockPlayer, i think it was, and damn... looked like 1fps!

I tried to play a mkv file yesterday with the build-in player which crashed my phone.
I installed qqplayer and am pretty satisfied with the result.

What kind of mkv did you try? 1080p?

I keep saying its a software issue causing all these troubles, i have a Adam and since the latest update i saw a improvement on the video playback.
Once we get proper support for mkv it will be awsome

Do you have a video of the adam playing back mkv?

You can search in the thread @ my sig for " Notion Ink Adam Qi Vs Motorola Xoom by Inspiron41 "
I can add that any file that i have MKV to be played has to have the extension changed to AVI and only QQPlayer can run them, if the sound quality is high more than 2 channels the fps rate will be low this happens with either 720p or 1080p. But if i try to run a MP4 file with 1080p it runs very smooth with audio and video sync, so for me its a issue with decoding of MKV.
Oh and the Adam is running froyo no multiprocessor support neither the video apps do.

[Q] [9003]Playing HD videos in mp4 format

Hi
Sorry if I posted in wrong place.
I just bought Samsung galaxy sl with super clear lcd. I am facing some major issues with playback of high definition videos in mp4 format. The default video player in my phone is not supporting the playback of high definition mp4 videos. I tried downloading at least 6-7 different video players from the android market but again facing problems. Some of the players like rockplayer and V player are able to play the same video but at a very very slow frame rate. The sound is alright but video playback is very poor with extremely slow frame rate. Its as if the video is being played in slow motion. The sound comes earlier whereas the video playback falls behind with slow framerate.
So any idea how I could play hi-definition videos is my galaxy s 4gb lcd version ?
Thanx

Stock player plays 720p easily
Ders also a Summer Player wic i like
Rock Player hs sound issues in mine...

Yes this sucks really. I have both galaxy s and sl
And s play unconverted mkv flawlessly where my sl have lag on it and also I need market play. I hope any developer modified sl player codec with original S model.
I know our sl have good gpu n cpu to run hd unconverted movie.
I hope some one will modify default play and ported S player to our phone. Like touchwiz 4.

The stock player is able to play 720p if I convert it to .avi
But mp4 is not running. I tried a lot of players from Market but to no avail.
Was not expecting this..

same problem here.. most of the videos i downloaded were 720p.. but most of the time when I try to watch the videos, frame rates were to slow... but the audio was fine,.. hmmmm?!?!

Have you tried moboplayer ?

Download Handbrake and use it to convert your videos. Since it hasn't played on 6-7 players it's likely there is something wrong with the file format. Try converting to .mkv again with one of the presets.

720P or 1080P? please try to use 手机QQ影音(Android)1.0 Beta3(168) it will be OK!

I recorded a video at highest quality and 720 using SGSL but when played they play like scatched cd or dvd, video and sound doesnt match and sometimes the video skips.
Can someone suggest. The videos are recorded on external sd card.

Its due to you ext sd quality.most probably its class 2.you need at least class 6 sd for optimum result.

where can i find this?

I've researched a lot on this topic and found that its due to our omap 3630 chip set. Its not powerful as galaxy s hummingbird. It can play 720p mp4 but not handle 1280*720 mkv no matter what you do.
I have both galaxy s and sl.
And I recently flash both with best roms available with lagfix.
What I wonder to see that smartcine n quadrant score of both.
I. Cpu part they have little difference.
2. But in graphics u have seen nearly 60% more score of galaxy s over sl.
That is the reason sl sucks in this section means hd playback but.
But after flash xxdb3 n lagfix on my sl. I am able to score mkre than 1900 on quadrant where my galaxy s score 2700.
I dont think any player from market can play mkv in hd smoothly.

i9003 can't play mkv because it don't have drivers to understand this format in stock player. If you are using other player in not system mode this means that it don't use video aceleration at all.
IE we just need native drivers for mkv and other formats

1080p video playback

is it possible to play 1080p video? i tried on mx video player but no luck. 720p plays fine.
Im asking this because, a couple of days ago, I got to play with a tablet. pretty low end with 1ghz and same resolution as OB but it plays 1080 video.

Due to the OB screen size, I think it is useless to play 1080p (and 720p).
But anyway, I don't know how to play it. Tried with Mobo Player?
Envoyé depuis mon LG-P970 avec Tapatalk

The single core can not run the 1080p, it's slow.
For 1080p request minimum dual core!

mobo wasnt able play them
yh i kno tht 720p will b enough for this screen. but converting a big hassle for me.

I'm sorry xD!! Buy a dual core

but it's also useless
i found no difference in gs2 between 480p, 720p and 1080p
(a little between 480p and 720p) not in 1080

hehe yh like i said, not much difference when it exceeds 720p...but the hassles of converting....
the reason i was asking this was that tablet was able to play 1080p on single core at 1Ghz. it was on ICS.
but well, guess i just hv to convert...

can't play 720p h264, sucks big time

No its able. Custom patch the 1080p recorder app to make it compatible with single core. But of course the performance of the video record is quite of a disappoint.

YouTube problems

Hi all,
I started out with the stock 3.2 ROM, I quickly switched to Overcom ROM 3.2. I was happy with it for about 8 months.
Then I decided to go to ICS and later JB.
Every ROM I've used so far has the problem that HD movies on YouTube don't play very well. Every few second it will stop for a fraction of a second, it's really annoying. The audio is never affected though. It happends when the video is small and when it's full-screen. The moment I switch from HD to HQ the problem is gone.
I tried about anything, even overclocking up to 1.5 GHz. doesn't change a thing. I'm pretty sure it's not the capabilities of the tablet, if I play 720p trailers on the IMDb app it plays all video's perfectly. Also, when I use the 3.2 Overcome ROM backup the problem is gone as well! I can't go back to 3.2! I love ICS and JB too much!
Are other people having this problem? Or does anyone knows the solution?
I was wondering if this has something to do with the kernel, so far I used the A1 kernel and currently I'm on 3.1.10 Cyanogenmod+ kernel and CyanogenMod 10, with Android 4.1.2

Again, from the Asus Transformer Forum about the Tegra 2 and HD content -.- :
"The Tegra2 chipset are designed as a mobile sollution chipset - to support web 2 standards. The highest encoding profile used here (Youtube 1080p) are 1080p baseline and this the Tegra2 chipset will both record and play with no troubles. As well as 720p baseline and main profile - but only upto L3.1 with some limitations. It doesnt matter which container is used (mkv, mp4, m4v, avi etc) and it doesnt matter if resolution are 1080p - its only a matter of the encoding profile used to encode the supported video format H264
Tegra2 will NEVER be able to decode High profile L4.1 encodes - it's not a software issue, neither in terms of Honeycomb or Nvidia libs, its simply a limitation of the abilities of the hardwaredecoder in the Tegra2 chipset and this will never change. It is also not a limitation in the Transformer specifically, but a limitation in ALL Tegra2 based tablets and mobilephones.
This is the same reason why some mediaplayers like the Boxee Box that was originally intended to use the Tegra2 moved on to an Intel chipset before launch.
In short the Tegra2 chipset will support playback of videos encoded in 1080p or 720p resolution, using the H264 video codec and AAC audio codec - as long as the video are encoded after the baseline profile standard
It will not now or ever - play 1080p/720p encodes encoded after the high profile standard."
Youtube HD is not encoded as it has to be for Tegra2 chipsets to play without stutters..
Next time, please serach the forum, there has been several threads about hd content.

While I agree the issue was mentioned before (it's even on my faq ICS), none of your reply addresses the observation, made by several folks on this board, that certain (youtube) HD videos played fine in HD, but stutter in ICS. Or did I miss something?
I read a suggestion somewhere, that video would stutter less in ICS (correction: jelly bean) if developer USB debugging mode is off, but I didn't see a difference...

Well, i have to admit that youtube hd videos did not play fluently on HC for me. Therefore I think that the android version or kernel doesnt matter for decoding. I might be wrong though..
With that being said, i think that there is no solution to get it fixed.
Btw that USB debugging thing does not work for me as well

Which rom best for watching videos?

I like to watch movies on my tab, then and often stream them from my pc. I'm just wondering which rom you guys would choose as the best for this? I'm thinking of going back to the cm9, currently on 10.1.
I seem to remember having less issues when using cm9 to do this, though in general I didn't find the rom ass smooth. But many of them are 1080p and I'm not interested in reincoding anything.
And is mx player still one of the best options for this?

Honestly, I have no problems streaming and watching my 720p collection from my HTPC on my stock ROM (4.1.1). I am using MX, and even though it didn't request a codec, I still installed the ARM7-NEON codec. I have abosolutely no problems whatsoever. However, all my 720's are very efficiently compressed using my own settings with max bitrates not usually exceeding any more than 4,500kbps.
Sungsonic is supposed to be optimized for video and audio. But not sure if it is available / works on the P1000. I'm currently on a P3113.

I also had the same issue, I also love watching movies on my Tab, especially HD. I was on cm9 then shifted to cm10 parandroid. All of these custom ROMs have same issue with playing 720p and 1080p. The solution I still use is this:
1) delete all codecs and players, including MX player.
2) install bsplayer
3) then install mob player
4) then install MX player (don't install its codecs or the other players codecs)
5) go to MX player >>> settings>>> decoder>>> tick the hw+ decoder and at the bottom tick the deinterlace option
6) now try playing 720p or 1080p, in hw+ mode using MX player. If the player still lags you can use BS player, it handles HD quite well and slightly much better than MX player.
Hope this works for you. Please reply ASAP of the results...

Thanks for the suggestion. I ended up doing a full restock last night, and gave it all a go in the gb again, and am now back on the cm9, and it's working much better. One movie I stream as my test was always a bit juttery on cm10 variants, and also on gb is very good on cm9. And of course mx player will select hw in cm9 where it won't in the others.
Sometimes you just have to trial and error. Actually, everything is running a bit smoother than any cm10 I've used.

It's a fact that 1080p is VERY BAD on JB aosp based roms even with hw support, when they are played absolutly nice on GB rom !
About JB 4.1.2 not able to play fluently 1080p as stock GB samy does, one of our rom daddy explained somewhere that Samsung have some kind of proprietary codecs bought somewhere that aosp cannot have. So...
But I just tried ICS AOKP SGT7 milestone 6 (19/9/2012) and it decode 1080p flawlessly ! no difference with stock GB !
So what happen to JB 4.1 or 4.2 ? :cyclops:
edit : got a look at the 1080p' movies link used to Test videos for HW codec with MX, for example at the [ROM][CM10][JB][4.1.2][SGT7][P1000/N/L][PDroid][20121127] thread when guys complained about bad performance, and I discover that theses "reference' movies" were in fact both 800 or 816p ! along with a fanny readme that states "Original Video properties: Resolution: 1080p (1920x816) FPS: 23.976 (NTSC)"
So I think that many dev' validation test could have been badly abused that way with something near 720p !
It could be nice that our "old" 1080p mkv could stay running and streaming over our tab ... in JellyBean kernels & roms ad hoc !
Please ...
Thx
