[Q] Video format support status?

What is the status of the Tegra 2 video decoding abilities right now?
I have been hearing about issues with high profile H264 video decode in 1080p. Does 720p H264 HP work?
Can someone test with the test cases and report back: http://imouto.my/watching-h264-videos-using-dxva/
Under TEST VIDEO FILES
I read somewhere that it was ROM dependent as well?

I haven't gotten anything to work, video playback was a big reason for me buying this thing (I've since found other great uses for it though). I'd like to figure this out, I have a ton of 1080p h246 videos in mkv I'd convert if I just knew what to convert them to. I'd also run those test files for you but I can't download it b/c I'm not paying for a membership to some download site to get the files.

h264 high profile does not work on the Tegra 2, but h264 main profile works. The high profile issue is a hardware limitation in the Tegra 2.
You can check your mkv's with a tool like "mediainfo" (http://mediainfo.sourceforge.net/en). It will show you your video details.
As for mkv's themselves, I believe that the device has issues with that container, as opposed to MP4. I can get standard def MKV's to run fairly well in Rockplayer, but haven't delved too far with high def. If you are going to transcode, you're probably better off with an MP4 container.
I'd also suggest that, if you are going to transcode anyway, probably stick with h263 as that will give you the least amount of headaches. I don't know how easy it is to pick the profile in h264 - every app I've tried (so far) encodes in high profile. You might have some luck with something like ffmpeg.

Really? My ZT-180 can play Blu-ray rips to 720p, but not the 1080p rips. It is a lot less powerful than a tegra2.
As for the the quality of my rips, I used ffmpeg, and don't recall using any "high profile" setting. The 720p rips were around 1.8GB in size. Since I found very little info on how to use ffmpeg, I chronicled my experiences in this thread, so others have something to follow.:
http://www.avsforum.com/avs-vb/showthread.php?t=1219959
The last post contains info on how to re-map the audio tracks. The ZT-180 had trouble with the 6-channel sound tracks I encoded into my rips. I don't know what audio the tegra2 can play.

With regards to the ZT180 (Infotmic X210), the DSP offloading methods are adopted from mass produced MP4 products, so I am not surprised if they play well on that device.
So basically the Tegra 2 doesn't even do 720p high profile confirmed?
Is the MKV container issue a software or hardware issue? The Tegra 2 SDK is getting updated continually. Or should I ask this question over at Nvidia's forums

right now viewsonic tablet has problem playing high profile video. i guess rockplayer or vplayer are not yet optimized for tegra2.

vplayer doesn't even work for me. everytime i browse to a file and try to play something, it just throws me right back out to the app.

The high profile issue is why Boxee dropped the Tegra 2.

I saw that before, but that only pertained to 1080p and not 720p

I'm thinking that it's a driver problem as nVidia's still claiming 1080p as are all the other Tegra 2 based devices... e.g. LG phone, various tablets, etc.
I did turn up a reference to laggy 1080p video in the nVidia forums, but they seemed to think it was a poorly encoded video as they had one that played fine while a second was laggy. Noone from nVidia commented in that particular thread though...

[Q] Can the Thunderbolt handle 720p HD video smoothly?

Howdy folks, hope some of you might have a few suggestions for a new Android guy.
After much love and consideration for the Android platform, I decided to come over to the Android world. Sold my iPhone 4 and picked myself up a Thunderbolt at the neighborhood Verizon store. So far, I love it. Great device, screen, customization and service. A world of difference from AT&T. However there is one lingering issue.
On my iPhone, I could send 720p direct from iTunes to the phone. It played smooth as silk, nary an issue, perfect.
With the Tbolt's fantastic size of screen, I would think it would be the perfect place for mobile HD video. However, when I take an mp4 onto the Tbolt, it chokes. The playback is varying levels of choppy, and audio often loses sync.
Am I doing something wrong? Is the Tbolt not capable of playing this type of file? I see a lot of talk on the forums about Froyo messing with 720 playback. I'm not sure what to do because aside from that one issue, I love the phone.
Any feedback/advice/info is appreciated. I love Android and so far the community rocks.
Signed,
Former iPhone User

i had the same problem. installed "vplayer advanced" and it was much better - no skipping, no sync issues. i think you just need to find a different player. the hardware should play them fine, but i havent tried a 5 gig 720p HD movie yet. and the default player wont play mkv files, but vplayer did.

You guys do realize the thunderbolt's screen is 800x480, which is a lower resolution than 720 (which you normally think of in terms of 1280x720 resolution). The horizontal scan lines on the thunderbolt (480) is the same as a standard definition television (640x480), so all you're getting is a placebo effect and a huge drain on your phone battery/resources.

Totally understand this. However, for me its more an issue of ease of use. I don't want to convert videos 3 times because I have 3 devices, which was the nice thing about the iPhone/iTunes. One file, done.
Plus, I've downconverted the videos to test, sometimes they skip too, and they never look as good to me. Placebo effect maybe, but again the ease of use thing is the biggest importance to me. If the iPhone 4 can handle this kind of file, why shouldn't my Tbolt?

Problem is probably not the hardware (since the thunderbolt outdoes the iphone in this), it's probably the codecs on the phone not being adept enough to handle them or the developer of your media player not keeping up with certain advancements in android hardware.
Just for instance on a pc, coreAVC will work on really old computers for x264 hd movies (ive gotten it to run smooth on pentium centrinos), however, the built in codecs for something like VLC player (last I checked), couldnt handle a computer that old for rendering HD.
The other issue could be how well they (both the android os developers and the media player developers) take advantage of using the hardware to do all the heavy lifting in the decoding. If it's all being done with software (like VLC does by default on a pc), then that is going to kill the cpu. If it's leveraging the gpu in the phone to take some of the burden off the cpu (similar to what something like coreAVC does now on a pc with nvidia's cuda), then that would help immensely. If in fact android can leverage the gpu to handle things like video decoding, then the final issue is whether or not the developer of your chosen media player is taking advantage of that.
However, if it was some sort of hardware issue, it could be the read speed of the included sd cards http://en.wikipedia.org/wiki/Secure_Digital#Speeds. Try sticking a smaller video file directly in the internal storage of the phone and see if that makes a difference.
I haven't looked too far into the internals of the typical android phone and os yet, but coming from many years of linux and windows development for the web and desktop, those are just my thoughts on the issue.
Android OS 3.0 has an encoder built into it already for h264 avc, so that should take care of issues in the near future for converting your video. Whenever we get gingerbread finally (well 2.3.3 that is), we'll have vp8 decoder as well and that should run things much smoother as google built it themselves for html5 video streaming, so I'd hope it would run efficiently on android. I've read issues with people not being able to handle high res MP4 files on the inspire (the att's thunderbolt) so it doesnt overly surprise me you are as well. I assume they are h264/mp4 files, right? Perhaps try encoding to h263 if so or wmv
http://developer.android.com/guide/appendix/media-formats.html#core

Yeah your gonna have to Download a Video Player app that is Hardware accelerated and plays those kinds of Video Formats. Rockplayer should work too i think.

Been up all night loading my anime + tv shows on the bolt. I agree, i really don't want to be bothered with trans-coding everything i have, plus the bolt does has DLNA capabilities which is another plus if you have a server loaded with the proper media but chances are, those are 720p or better as well.
The best player i used so far is rock player, it beats out meridian, qq player, and vplayer advanced as is the only player that played back everything i threw at it. that said is not pefect, it drops frames when you try to playback 720p mp4 but still smooth for the most part. It lags a bit more with 720p mkv, and lags really bad with 720p avi files. Anything not using the native hardware decoder however, sucks a ton of battery life out the Bolt.
it will playback almost anything at 480p, which is about what the screen native resolution is at. The Bolt does come with a Adreno 205 gpu but i don't think that does anything for video acceleration, maybe is missing the proper hardware decoding chipset which is why is not armed with a HDMI port.
It should only get better with improvement in software/codec but for now, is a let down in terms of video playback.

Try Diceplayer 1.3.0
Thunderbolt's QSD8655 can play H.264 720p.
but HTC's stock media player can't handle MKV, DTS , Flac.
Diceplayer take advantage of hw decoder.
it can play MKV(+DTS+720p).
Don't worry about battery life. diceplayer use almost same power as stock player.

MoboPlayer with ARM V7_NEON coded plays everything fine.
http://www.moboplayer.com/moboplayer_en.html

For reasons stated earlier there does not seem to be any good solution that will handle all common formats used in a PC/Mac/Home theater system on a Tbolt without re-encoding. I posted a video player "shoot out" of sorts over on the "other" forum. In short I was completely let down by all the players I tested. There are a couple here I did not include at that time.
http://forum.androidcentral.com/ver...layers-review-test-comparison-included-3.html
The only one I left on my device was MoboPlayer.
Don't bother with files larger then 4GB either, our SD cards do not support them (or was it the OS...). That being said a good 720p rip with 5 or 6 channels of audio (yes I know there are not enough speakers to hear them all - just so no re-encode required) should generally be smaller than 4 GB.
I am quite keen to hear about any diceplayer vs. MoboPlayer as I did not test diceplayer.

I did some quick testing of diceplayer. It is no good. I used the same blend of file types, video formats, audio formats, files sizes and audio and video quality as my tests I posted about with the link to the other forum (prior post in this thread). Diceplayer was very bad. It played 1 out of 4 of the files I tested. Some played but had garbled audio or a very slow frame rate meaning effectively no successful play. I found Moboplayer to be slightly better than Diceplayer.
We really need an equivalent to VLC for Android. VLC as anyone can testify is the "swiss army knife" of players. Plex is the only app better than VLC in that it can output DTS and Dolby via optical (not concerns for a mobile device obviosuly). Who can or wants to re-encode a multi terabyte movie library?

[Q] HD Movie playback is jumpy

We just got a Asus Transformer, and it's pretty cool ... mostly.
One problem I've seen is that the HD Movie playback is really choppy. I ripped my copy of Planet Earth, and ran one of the M2TS files through FreeMake to create an Apple TV H.264 / AAC MP4 video file.
When playing back on the Transformer Media player, the playback is really poor (unusable, actually). Is the Tegra2 embedded GPU enabled in the player? If "yes", I'm pretty disappointed. (Who makes the Asus player?)
If "no", is there a free player / update that enables the hardware decoding?
Thanks,
¿GotJazz?

Pretty much the video playing is limited to low profile for now.
We're all hoping that Honeycomb 3.1 fixes it, although some people are convinced it's the Tegra 2 processor and cannot be fixed by software.
(Hope they're wrong! )

Thanks! Good reading there.
While searching XDA before I saw your response, I found that some folks were using RockPlayer. However, now it looks like I may want to check out MoboPlayer, too.
Cheers,
¿GotJazz?

I just tried Moboplayer and Rock Player, both with Tegra2 hardware acceleration enabled.
From what I saw, Rock Player handled my HD content better. There were audio drop-outs in Moboplayer, and the playback was a little jerkier.
Rock Player wasn't ideal, though: While it played the content better without the audio dropping, the FPS display was averaging 10->11 FPS, though it was significantly smoother than Moboplayer.
¿GotJazz?

Tegra 2 CAN handle high profile 720p, it CANNOT handle high profile 1080p. However as stated honeycomb or tegra 2 drivers need an update.

There is no hardware acceleration in either of these apps. There is only software rendering (with the code optimised for the Tegra2 Arm core) or a thin layer over the default movie player. One or the other.
And the official specs for the Tegra2 SOC stated no ability to play HD h.264 high profile. We are currently prevented from playing Main profile as well and that _may_ be fixed but it's very unlikely that it will ever do High profile.
And no app will ever solve that, they just don't have enough access to the hardware.

I was talking about High profile, I stand by my previous statement that the SOC can handle 720p Main (and 1080p Main using CAVLC rather than CABAC) even if the current honeycomb binaries don't let us.
What is interesting is that you should be able to switch between CAVLC and CABAC losslessly without re-encoding (Something akin to re-muxing) but there are currently no tools to do this.

Silent Mobius: I'm not disagreeing with you (since I don't have the detailed experience), but before playing the movie, RockPlayer v1.7.2 had a pop-up that asked whether I wanted to use "Hardware Decoding" or "Software Decoding". I saw a big difference in playback between the two options.
Is RockPlayer mis-representing their functionality?
Also, is there any way for me to know if I am using "High Profile" encoding in my MP4 encoded file?
I basically used the default settings in FreeMake for AppleTV format.

I use handbrake to re-encode all my HD movies. I followed the thread below and everything plays perfectly. Yea, it kind of sucks to have to do this but it beats the alternative.

The default Movie player simply wraps the "MediaPlayer" object any time rockplayer/moboplayer mentions "Hardware acceleration" they are talking about use of this object.
Now it is possible that the default media player does a little extra filtering (for example just flatly refusing to play any main profile video) rather than letting the MediaPlayer object decide, its also possible that overlays and cruft could make one of the two (mainly fortware) players play with varying frame rates when just reusing the MediaPlayer object. I'll knock up a _very_ bare bones media player app tonight to see if will play main profile.
To see what your encoding is coming out of I recommend getting a copy of MP4Box it provides the most useful information

[Q] How can I Speed up S/W decoding on LOW-END Device

I want play some 720p video on my phone, tried with few TWEAKS(V6 SuperCharger, Modified Build.prop)

Please Help... and sorry for my bad English

This is a hardware issue, your phone doesnt have enough power to play these kind of videos.
Maybe if you reduce video bitrate, it will be playable.

Your only real option, is to reencode the video to a lower bitrate, and/or to a format that's hardware supported by your device. Handbrake is an easy to use reencoder.
Looking at GSMarena http://www.gsmarena.com/htc_desire_200-5536.php it seems your phone should be able to play H.264/AVC format.

First look how much cpu and RAM is consumed. You can use apps like lucky patcher or disable service to dissable unwanted running service, do not move mx player in sdcard, always keep some free space in internal memory, exit apps like viber.... while playing 720p videos in sw mode, do not create lot of widgets. I have same amount of hw in my ray and I can play any types of 720p videos smoothly with sw decoder. MX player uses internal modules so if mx can't play means other apps too cant

It's because your cpu can't handle the load.
S/W mode will ffmpeg library & entire decoding will be done on CPU. So, there is no way to fix.
Goto Settings 》 Decoder & enable speed up tricks. It may affect video quality. But, may reduce the lagging.

Using SW, even with speedup tricks, will still drain your battery as your CPU's running at 100%. Reencoding to a HW supported format as I previously suggested, will increase performance and reduce battery drain.

I have a motorola bravo that I bought in 2011 which is almost the same (1ghz TI OMAP, 512mb ram) and when I try playing 720p videos, it is really slow sometimes.
The only way I can play 720p videos, it is reducing bitrate else convert resolution to 480p or lower.
Else change your phone!

[Q] Laggy when playing video 1080p with VP9 video format

Hi, Recently I've downloaded video 1080p from youtube but when playing it, the video laggy but the audio just playing properly fine...
I thought it because the decoder set to H/W, but when switched to S/W both video & audio become laggy, then try switched to H/W+ it become worse (doesn't support this kind video it says...).
When I see media info of video, it use VP9 format video.
Here is the video: www[dot]youtube[dot]com/watch?v=aE2GCa-_nyU
I've tried on 3 devices; Asus Zenfone 6, Samsung Galaxy Note 10.1, and LG G2, all of it have the same issues...
And tried on PC to check if the video has errors or something, but the video is playing perfectly fine.
Is it something like bugs so the video didn't play properly? Or android can't play video with format VP9 properly?
Because I've tried other video 1080p, it can be played properly.
Oh FYI, I've tried using few other video player, and none of its can play the video as good as MX Player. That's why I've been using MX Player as default video player.
Hope there will be improvement on the next update so the video VP9 1080p can be played properly
MX Player is the best

All 1080p videos are not same.
It may lag at various parameters like higher frame rate, bitrate, color depth,....etc.
For example if you consider a video 1080p @ 30fps inorder to display 1 sec of videos it needs to decode 30 frames. Where as in 1080p @ 60 fps it requires 60 frames to be decoded. So, It will require the double power. Like wise various encoding parameters matters in video playback.
Second, H/W uses your hardware's native decoder . If the codec is natively supported by your device, H/W decoder will be the best option.
In case of S/W decoder, it supports more video formats since it depends on the ffmpeg. But, decoding will be completely done one CPU. So, it needs very high cpu power. That's why it's more laggy.

Hi, Recently I've downloaded video 1080p from youtube but when playing it, the video laggy but the audio just playing properly fine...
I thought it because the decoder set to H/W, but when switched to S/W both video & audio become laggy, then try switched to H/W+ it become worse (doesn't support this kind video it says...).
When I see media info of video, it use VP9 format video.

VP9 isn't a widely supported format. That's likely why HW and HW+ don't work well with it; most devices don't have VP9 hardware acceleration.
SW rendering of a 1080p video is very demanding. Even on the most powerful devices, since there's no hardware acceleration, expect performance to be sub-par. Currently, devices on the market can only SW render 720p smoothly.
This being said, for SW mode, try Settings > Decoder > use speedup tricks. See if that helps a little bit on SW.
Ultimately, the best option is to reencode the video to something like H264/AVC mp4.

VP9 on KitKat+

Can you explain more where you're trying to playback the video? VP9 support is built in to Android from KitKat+ and should not have an issue playing back. Additionally, can you try playing back the video on Chrome on Android and see if there are still decode issues?
Thanks.

I see... So the point is the problem because most devices don't have VP9 hardware accelaration yet, especially for 1080p VP9...
Well... I've tried using SW speed up trick, it didn't much help...
Yeah...maybe the best option is to reencode the video to H264...or download 720p version..., cause the 720p VP9 can be played perfectly fine.
Still... I hope the MX Player developer team has plan to improve playback for 1080p VP9 video
Btw thanks for your answer bro

As I said before, I'm trying to play 1080p VP9 video (that I've downloaded from youtube using IDM on computer) on my Asus Zenfone 6, Samsung Galaxy Note 10.1, & LG G2 using MX Player.
But when I playing it, the video is laggy on all devices...
Surely you can streaming it using youtube app & chrome android and it plays well till the end cause the available quality option in those apps is up to 720p (the 1080p quality option is hidden on those apps so I can't select it to test if it plays well or not).

That would be something you would have to ask the ffmpeg team to do, since MX uses their codecs. Unless the MX dev has a magic trick up his sleeve, I don't think there's much else MX can do to further improve SW playback performance for a video that exceeds the CPU's capabilities...
Likewise, on a hardware acceleration, it's limited by the hardwaree put in place by the manufacturer... so this aspect would need a new device.

Hi, i bumping this thread because i encountered the issue on some youtube vids too, but it's mostly playing fine, i think that with a few updates it will be good my phone is getting hot fast though.. (oneplus one)
VP9 1440p https://www.youtube.com/watch?v=mNNfZuIA1GQ : fine
VP9 1080p with a lot of "motion" https://www.youtube.com/watch?v=KGyZY4HNumw a bit laggy

I think I have already answered.
Read the second post. Video encoding parameters matters.
If you can't play in H/W or H/W+ decoder, Don't expect the smooth playback on S/W. It fully depends on CPU. If is laggy then your processor is not powerful enough. Sometime enabling the speed up tricks may reduce the lagging.
One more thing, using CPU will drain your battery faster than H/W. When CPU runs it's maximum speed for long time it will emit more heat which may lead to issues.

Okay thank you. Then i hope new processors will have vp9 decoding h/w

The chance of that happening, I can't see to be high. The MPEG consortium probably pays a lot to lobby chipset makers to only support MPEG formats, such as H.264 and H.265.

Lolno, it's just that industry is not interested in VP9. Even if they don't have to pay royalties they still have to develop asics (and h/w engineers are saying that it's not h/w friendly) and include them into the chip. It still costs a lot.
And what is the point of supporting vp9? It's an ugly google toy that they're ready to abandon (say hello to vp10 in 2015).

Ah yes, ASICs. I don't think manufacturers would be very happy at making more dies for new ICs. They already aren't happy with being forced to support Hi10p in H.265.

Forced? I would be happy if they were forced, but, at least Qualcomm, have no plans whatsoever

Well, this sucks. Looks like we'll be waiting another generation... Where did you find that support chart?
Edit: We should move this discussion to the 10-bit thread. I'm going to quote you over there. http://forum.xda-developers.com/app...layer-10-bit-video-discussion-t2725241/page12

abput supporting vp9 1080p and undeleting files in mx player p higher andrpid version
first of all:
"Most probably you’re on Android marshmallow 6.0 API. If you’re trying to delete a video that is located on the external storage then its not possible due to some bug in the file system and mx player.
If you’re on the internal storage then MX player has only read only rights on the directory on which you’re currently on."
or just delete on your internal system file manager application.
Second answer about playng videos vp9
becayse you can't play vp9 if you download youtube videos with IDM (internet download manager)
because it is bull**** and its newer versions used idmmkvlib.01 codec.so when downloadimg it not only download andit convert into ist bull**** special format.so won't play withx pr others.try another downloader or manual download yt videos i recomend.
