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.

Various Video Format Playback (i.e. AVI)

Hey everyone,
I thought this was an appropriate place to discuss the viability of multiple video format playback on the legend. I've been trying out all the different apps that claim to be able to play an impressive array of video formats, but none of them can play a simple avi video file (even though it says avi support/playback in the app descriptions). Most just crash, or the video just doesn't play.
So, my question for you is, have any of you discovered a way to watch avi files, or any other video formats on the legend without flat out converting it to a playable format? (ex wmv, 3gp, mpeg are the ones supported i believe). Post your comments/thoughts/experiences! Not so much a question as it is me creating a thread for the discussion of app development for this problem (not technically a problem), or even integration of this added functionality to our fantastic bunch of ROMs cooked up by our friendly neighborhood devs.
Thanks,
Michael

I think there is nothing we can do about the inferior hardware on Legend. Compared to the N8 and C7 that Nokia gave me, the same ARM11 cpu but the Nokia came with Broadcom GPU that does include hardware video acceleration. It plays 720P with ease.

With rock player I did watch avi files.. (the normal 700mb files)

no its doesn't.
It will play .avi files but not 100% smoothly like on pc... but it is playable.
and note: yxplayer is not working for well on android 2.2 and it doesnt work at all on higher > 2.2

yxplayer sucks. Rock player is really the only decent multi format player. Unfortunately doesn't work very well in CM7

I have been using summer player on cm7 and it plays avi files.

Screen Mirroring... Do we have ANY options?

I know there is no MHL - even tested to be positive and it doesn't work - however, wondering what other options potentially exist for screen mirroring to a TV?
Not interested in DLNA (I've used Skifka/similar and it's good) but I want to mirror so I can stream anything from the N7 (games, Hulu, etc.) to my TV.
Thanks!

"Android transporter" with a raspberry pi may be an option in the near future. I already have a RPi, so this would be awesome for me.

Does it support Hulu or other streaming services, or just media that's on your local device? If the latter then it's the same as DLNA/Skifka.

if you have a Roku hooked up to your TV already, there are separate channels for things like Hulu and Netflix. You would stream to Roku direct over wifi from internet, not through the android device. The Roku juice channel and application just enables you to stream media from the android to the TV through Roku. I have only tried it for pictures, and not with Jellybean yet at all. I doubt it works unless the media is located on your android. I can test tonight when I get home, I'm at work now.

I am not sure if it will even support WiFI Direct Display mirroring as has been demoed on the OMAP 4 series chipset. As, that was one of the advantages the OMAP4 had over the Tegra 3. In either case we haven't seen a lot happen with that either.

Just an update to my post, I tested the Roku juice demo on the nexus 7, it seems to work for local media and had a podcast option I didn't know what to do with. But no streaming of games.

If i get install the Nexus & with the plex app and use it to stream the content to the roku box ( $50) version would that work always for audio video and images? And when I have the roku and the tablet set u on the same wifi network...would streaming from my nexus to the roku use my data or bandwidth?

You would install Plex server on a PC, and the Plex media channel on the Roku, and/or Plex media app on the android device. With this setup, you could stream videos from your PC, or from the Internet (if using Internet channels like Hulu) to either the Roku, or to your Android device. The Roku uses your wifi network, android devices can use wifi or cellphone data.
If you are trying to stream a video saved on your android device to your TV, then you don't use Plex. You would need Roku juice installed on the android and on the Roku box too. Note, I only tried this with their demo app, which is limited to the first video and I did not see the Transformers video in the list. I don't know if that is a demo limitation, or if the Roku juice app can only stream videos you record on your android device.

[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.

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
