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.

Does nexus one can playback 720p High profile videos?

LG's Optimus Q(LU-2300, only for south korea) has same snapdragon 1st gen 1ghz cpu. But it can play h.264 high profile 4.1
Both devices are using snapdragon.
It is possible that play high 4.1 videos on nexus one?
Sent from my Nexus One CM7 using XDA App

LG probably has licensed codecs and a modified kernel to take advantage of said proprietary codecs. I did a quick check online and couldn't find any mention of h.264 playback. The only mention of 720p is for the camera.

Quote from Wikipedia:
"There is built in hardware decoding for H.263, H.264 and MPEG-4 video"
http://en.wikipedia.org/wiki/Nexus_One
It can also be seen in device specs.
So yes, most chances that the will be some video player that will play h.264.

hi,i used modaco's desire port for nexus one rom,and it surprised me with playing 720p in realtime,and also great camcroding on720p,i tried to play some youtube's 720p videos(downloaded FLV file from youtube)and it played it really really great,smooth,realtime!

[q] video laggy and stutters

Is this a common problem with all the Tab 8.9's or is it just me. I have a bone stock new Tab and when I try and play youtube or other videos, it stops every couple seconds and lags ... Wallpapers all look pixelated no matter what resolution I download ...I love the Tab so far, but things that should operate without too much tweaking or manipulation seem to require a lot of work to get working correctly. I hope I dont regret the decision of not getting an Ipad

Im sorry to tell you, but all Tegra 2 devices are unable to play 720p or 1080p videos without stutter. Even with an OCd Cpu it wont (some people say, but theyre desperate just like all of us..)
Other dual cores can because they have something integrated, that we call NEON. So its not about the cpu speed at all, its about a missing function, to decode HD material (overall video material, but the cpu can handle low resolution vids).
Some codecs on the market (for ex. BSplayer) can help but it'll still be a bit laggy.
EDIT: It is possible to play 720p or 1080p videos. You have to convert the video to H.264 Baseline profile. With that, it should work.

Try mxplayer. I found anything I recorded on my S2 would stutter like mad when played back on my tab but since mxplayer upgraded and added the hw+ decoder it plays perfect. As for youtube this problem has come up since the ICS update and not much you can do about it sorry

[Q] hd videos 1080p freeze

hi i recently purchased my lg optimus 2x in general i am very happy with my smartphone the only issue i have is when i try to play hd 1080p videos either with mx player or mobo the videos go very slow i tried the same thing on a samsung galaxy s2 and the videos worked flawlesly any recomendations how to fix that issue?

did you install mx player codecs for tegra 2? (you have them on play store as well)

yes i installed MX Player Codec (ARMv7) these are the ones anything else i can't believe that i am the only one who is experiencing this problem

Same problem... Codecs are installed for tegra 2 but video framerate is catastrophic.

Try to clear memory, hold home button then 'stop all'.

You made the mistake of buying this phone.
Anyway try Dice player, I find it superior to all other players

Did you try with standard LG Fotocamera? I never had fullhd problems with froyo/GB/CM7/ICS

Nvidia tegra 2 cannot decode x264 or h264 formats @ 1080P resolution. Try converting the videos to MPEG-4 @ 1080 Resolution.

No problems with fullhd videos, recorded on camera. We are talking about movies downloaded to phone i.e. mkv or mp4 fullhd movies.

Yes, i do encode and decode movies. SO AFAIK, tegra 2 cannot decode h264 codec.

Tegra 2 can decode 1080p coded in low profile. Medium and commonly used high profile are not supported. You can google what choices you can set up to have low profile video. Very good SW for recoding videos is handbrake. I wish you good luck with searching best encode configuration.

i downloaded the iron man 2 trailer 1080p hd video here's the LINK
i'm using mx player, temasek final build rom and stefan final symbiosis kernel
the video is sluggish to play and the sound is not matching when stark open his mouth for now i didn't using ICS rom or cm10
i also try to play the video in different decoder included on the mx player but it doesn't work

You can run 720p or 1080p fluid.. spawndk from the eepad transformer forum:
"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."
So basically, you have to reencode videos just like on ipad..

you should reencode to low profile, high profile is for blu-ray device or PC. don't know maybe exynos 5 can play high profile [email protected] with handheld.

Thread moved. Please post all question threads here in Q&A in future where they belong.

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
