Guys,
Can someone enlighten me on whether playing HD 720p hi profile H.264 files are a h/w issue (Tegra 2 limitation) or a s/w issue (Honeycomb drivers/video player app limitation)?
I keep hearing it's honeycomb (and hence s/w issue which should be fixable by s/w udpate) and then I hear it's Tegra 2 issue (and hence h/w issue which can only be fixed with Tegra 3 device).
If it is Tegra 2 issue, I am leaning towards canceling my order and waiting for Tegra3. I have a lot of videos which are H264 720p Hi profile that I was hoping to watch on the TF.
I currently have a SGT which will tide me over....
What I would like is some confirmation that is indeed h/w issue....
Here is a response from another thread from a member that thinks it is a h/w issue:
<quote>
Its not a honeycomb issue. Its a tegra 2 issue and it is not a software issue its hardware. H.264 does not work good or at all. You have to use MPEG4. I used a 720p video that plays great on my ipad 2 and had to convert to mpeg4. I tried to get good quality from MPEG4 and it increased the file size from 5.6 to 9 gigs. I swore to never buy a tegra 2 device again after testing other tegra 2 tablet & phone but I keep getting sucked back in by the hype. I hate apple but I have nothing but good things to say about the ipad 2. Everything just works and its way way faster.

But this says it is supposed to support hi profile 720p and base profile 1080p:

As far as my understanding goes, there are 2 HD playback issues here.
1) Issue with choppy playback of HD video files 720p or 1080p, its a Tegra 2 hardware issue, not a Honeycomb issue.
2) Issue with choppy playback of Youtube HD 720p videos using Flash, its a Honeycomb issue, which is expected to be fixed soon via an update.

And how do you know this? nVidia itself has stated that Tegra 2 is able to play up to 1080p main profile, let alone 720p main. If it can't, then the most logical reason is software not taking advantage of this. I highly doubt nVidia is shipping the Tegra2 with chip features turned off.
Correct me if I'm wrong here but isn't it a codec issue? I know moboplayer has codecs for the T2 but I'm not sure which codec to use since they have a bunch.

Srikar,
I am only talking about 720p Hi profile movie files that I will want to copy to the transformer for playback while traveling etc.. I am NOT talking about playing youtube HD playback in browser or via youtube app.
I know this is HC issue and will be fixed with the new Adobe bundled into next version of HC.
So we are only talking about issue 1 here...
It reference to the Ipad, its easy for Apple to optimized the OS to be very efficient because they control the hardware, they dont need to make the OS compaitible with different hardware, they can tailor the OS specifically for a processor to get the best performance
While on the other hand their is android, and Honeycomb was also rushed out, it may not have the best optimization for Tegra
I'm just speculating,
I am going to see what is announced at google IO in the couple weeks
Nvidia said the first Tegra 3 tablet is going to be coming out this August, and i have not heard anything yet, so my guess is we might see a Tegra 3 device towards 2012
Also note that performance can vary depending on software
On the MoDaCo ROM you can get over 3000 in quadrant, while stock Transformer from Asus can get around 1900
http://android.modaco.com/content/a...-custom-rom-for-the-asus-eee-pad-transformer/
Overall, i think the Tegra 2 is capable of playing HD video quite well, it is just the lack of optimization in the OS

That is exactly what I have been thinking, according to the fudzilla article I linked earlier, it clearly is supposed to be able to play 720p Hi profile..
Nvidia's own specs page doesn't give details on profile:
http://www.nvidia.com/object/tegra-2.html
but the wiki says 1080p main is supported, which I take to mean anything UPTO 1080p Main. (which includes all 720p), maybe that's where I am wrong?:
http://en.wikipedia.org/wiki/Nvidia_Tegra
Tegra2 can't decode main profile 1080p. It can decode files encoded with SOME of the main profile options though. What that means? That you can encode a video using specific options from main profile that are compatible with Tegra2 and it will play. The problem is - most of the videos available are not even main profile - the are all high profile. And on high profile Tegra2 just chokes.
Motorola had a fine specification what Tegra2 allows and how to encode videos for it. It's probably it: https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/63258/kw/video/p/7901,7906

Magnesus, understood on 1080p, but I am mainly concerned with 720p hi profile. i can live without 1080p until Tegra3. As you said, most available videos are hi profile.....
I'd love to see what the CPU and GPU usage levels are when playing back 720p main/high profile. Is there a widget that shows this?
I will experiment with the existing Handbrake profile to get the best performance/quality/file-size tonight based on that Xoom article. 4GB for a 1.5 hour 720p baseline is horrible. I have many 720p high profile 2 hour movies under 1GB, MP4, H.264, 2chan AAC, subs.
I'm pretty sure it is a hardware related issue. It's has been how many months now that Tegra 2 devices have come out? Nvidia would have release an update by now if it was software related. Also, look at the tegra wiki page, isn't it pretty obvious the tegra 2 has no high profile and neon support. If it did it would have been listed like in the Tegra 3 section.
From what I gather around the net, the problem seems to point at the weak GPU found in Tegra 2.
Has there been any progress with the tegra2 limitations on high profile HD videos, especially with 3.2 or will this never be fixed?
there are way too many high profile hd videos out there for this to not work on any name brand tablets (except Archos ironically and jailbroken ipad1/2).
For 720p try diceplayer. Works for most MKVs and is the best we'll get probably...

Yes. It is. There's a thread in the app section somewhere where the dev is actively talking to people on xda. It's worth the $4. I play 720P high profile videos often, but it takes either a really good SDcard, or use the internal memory. A slow (aka <10 mbps I think...my 6mbps usd card doesn't play well) card will make it not work. For obvious bandwidth issues.

Hi I just installed it and it works!
My high profile 720p mkv files are playing very smooth.
But I cannot understand WHY this the DicePlayer is the only player
that can play such files smoothly. Maybe it uses hardware decoding for video and software decoding for audio?

class 10 is 10 megabytes per second... in order for video content to exceed that bandwidth, it'd be 600 megabytes per minute of video, or 36gb per hour of video. Bandwidth is not an issue.
also keep in mind classes are WRITE speeds, not read, read is almost always faster than write.
I can't get the demo to play without sticking after a few seconds. Tried various 720p MKV's. Running off a class 6 MicroSD.
I tried this and now about 1/2 to 3/4 of my 720p files can be played smoothly.
Wondering though, the ones that do play, have a slight pixelated appearance to them, I was dissapointed in its visual appearance. I don't think its related to this player but the Tf in general? Perhaps bitrate is not high enough and that's why it was able to play?
The thing is if I play this on my archos 70 or ipad1 with XBMC, the picture quality is perfect, HD looking.
Anyone noticing this?
I find that curious as well. Noticed the same thing which wonders me since 720p should be mapped 1:1 on the transformer screen. But you can really notice the difference to a (baseline) encoded 1080p Video!

I played Rango in a 720P DiVXHD the other day (in MoboPlayer I believe), and I was really impressed with the quality (playing over the network nonetheless)... I'l have to go back and try it again and really pay attention to the visual quality of it. Overall though, I thought it looked great, and noticeably better than any of the 480p videos I play on it.
When I was saying that video playback gets stuck I meant I was using the Diceplayer 3 day trial version. Everything I played that contained a AC3 or DTS track caused the video to freeze after a few seconds of playback. FF a bit and it plays then freezes again.

Because the player is only using the cpu to decode the ac3 audiostream. Combine this with the load from the video-decoding and there is not enough cpu power. Even at 1500Mhz i have not enough power for all my mkvs.
I tend to forget that when I ran a 2.4Ghz AMD CPU on my desktop the highest res I could play were 720p MKV's most of the time. I am guessing some sorta hardware acceleration needs to be achieved in the codecs for it to play them smoothly?
I recorded a Full HD MP4 video with my Samsung Galaxy S2, where I can play back it absolutely smoothly. Then I copied it to my TF's internal SD card and it stutters like hell with the same player.
I would never have expected this, because both devices should have pretty similar performance hardwarewise.

Full HD is not good.
Tegra 2 only supports Baseline for Full HD. You should check the video and which profile it has.

But it should be. If you search Google for "Tegra 2 Full HD Video" you'll find several hints, that it should work like a charm, like in THIS product presentation video. I wonder, which player they are using in this demo.

Tegra 2 is able to play Full HD but (and this is a big but) only Baseline Profile.
And that's the problem: Baseline is dying which makes Full HD on Tegra 2 a useless feature.
I think it's this device/Honeycomb. I had no issues playing main profile with B-frames (no CABAC/Weighted-P or B-frames) on my Elocity A7 (Froyo). Same files do not play on Transformer.
I could never get CABAC to work, but even 2.35 cropped 1080p files played.
I'm really impressed that Dice can do mkv. It's very computationally intensive as far as containers go. Might have to give it a try.
Something's jacked up and one day it will magicly fix itself.
The main info thread said that 3.2 was supposed to have better media support. What works better?
I'm looking to a upgrade from my current handset, an old school Nokia 6120c.
What is most important to me is that the new phone (HTC Desire S) be able to play videos encoded at a "High:L5.1" level within a mkv container, or at least High:L4.1 as most 720p tv shows i got downloaded are at that encoding level.
Thee videos will not be played from local storage (Phone/SD Card) rather they wil be streamed from my NAS which is running TwonkeyServer.
The toss up over what phone to get came down to which had the better chipset, more specifically the better gpu in terms of hardware acceleration to play these 720p videos without a single stutter.
Not wanting to blow too muh dosh, im keeping it to a simple single core cpu, so I found myself stuck in deciding between the "MSM8255 Snapdragon" and the "Humming Bird" chipset.
The 2nd generation snapdragon has a snappier cpu however the humming birds gpu seems much better still.
So, heres hoping some of you guys have already given this a thought.
1. At what most encoding level does the HTC Desire S play videos stutter free?
2. Does Diceplayer offer hardware virtuasisation for mkv files (xvid/x264) on the Desire S?
3. Since Videos are being streamed by TwonkeyServer from my NAS, is their "less effort" for the Desire S to play these videos? As apposed to playing them from local storage?
I don't have an answer for your question but I do have a question for you.
Why do you need to watch 720p video on a screen that is less than 4"?
I have never understood this need for devices with such small screens to playback such high rez video other than that which has been filmed on it.
Surely a standard xvid would look just as good on the small screen.
^ not to mention that both the Desire S nor the Galaxy S have a horizontal video resolution of 480, so watching a 720p video would be scaled down significantly anyway.

Yeh it sure would, however i dont have the time or effort to be re-encoding videos all the time. I have "Sickbeard" download all the TV shows i have subscribed to my NAS box daily, so i would just like to stream the videos directly to my phone without messing around all the time with encodes and re-sizing videos everyday..

If you want playing 720p H.264 [email protected],5.1 video, buy Smasung(Hummingbird,Exynos) , Dual core snapdragon.
QSD8255 is not good at playing 720p H.264 [email protected]/5.x video.
1. 3.1 is Shutter free level.
2. YES
3. Subs have some problems. UPNP(DLNA) is not good for subs.

2nd generation snapdragon "MSM8255" with Adreno 205 GPU as opposed to Adreno 200 should be ~4 times quicker. So in theory shouldn't it be able to play videos of higher level encoding?
EDIT: Oh my bad, seems you were right about High:L3.1 being the highest shutter free level
As i turns out The HTC Desire S has the same chipset as the HTC Desire HD, which is actually included in the above supported list of devices. Well im **** outta luck then
Still dont understand how even with the 205 Adreno GPU it failed to play anything higher :S
I really liked the look of the HTC Desire S, and its dimensions closely resembled the iphone4 which i believe is just the perfect size for a phone.
so i was hoping that ICS would fix all the mkv issues since on my galaxy nexus every mkv i have plays perfectly.
but sadly that is not the case. MX and BS players are the best and only lag when theres a lot of things going on, like the final battle in thor.
anyway, my mkvs are all that high baseband or whatever, and i haven't bothered redoing them, or trying to convert them because i was hoping that ICS would actually allow them to play.
now that it hasn't, i guess it's finally time to convert them all so i can play them.
so i'm asking for help for a program that will allow me to convert all of these so that they can actually play on the transformer, but without any loss of quality, or any increase in file size. currently they're all around 7GB.

quick smart arse answer- stop whining, recode your goddam videos and accept the fact that the Tegra 2 chip is and always will be underpowered to play mkv's.

if you bothered to even read my original post, i asked how to recode them.
And i want to play mkvs on a 10 inch tab because i can't carry around a tv to school or on an airplane, and my tab has an HDMI out that i can plug it into a TV to play said videos.
also make sure you have the tegra 2 plugin for dice player, works fine for avi and mkv on ICS.
I use xenonmkv to transcode. It leaves the video alone but repacks the video and audio in a mp4 format. More tegra2 friendly.
720p mkv should play natively on ics as of now.I got them playing though I encountered an issue with audio not working with the stock app.
@bob dylan: i have the tegra2 plugin installed. dice lags so bad everything is unwatchable.
@pongo: sounds like an idea. any changes in file size? my mkvs are around 7gb, i don't want them to get any bigger.
@DarkLG: not sure how your able to play them, myself and many others are unable to get them to work properly on any player.

that defeats the purpose of this thread.... even a Galaxy S1 can decode high profile 720p MKV with dice player and stock, there should absolutely be NO reason why a asus transformer on a duo-core can't process 720p mkvs when a single core can.
encoding a video takes too much time and it shouldn't be necessary.

Why the hell you keep comparing Tegra 2 with Nexus's TI OMAP cpu assisted with PowerVR GPU? Despite same Cortex-A9 "base" architecture those are totally different CPU/GPU systems. All you see is that marketing bull**** with "CORES! Ghz!"?!
Tegra 2 is missing SIMD-instructions block needed to succesfully decode high profile/high bitrate h264 video in hardware accelerated mode. And you have nothing to do with it. Point.
And talking about high bitrate - 7GB sized videos looks like 9-10Mbps video stream for regular 1h40m movies. Thats way too high for Tegra2. Its upper limit is somewhere near 5Mbps. And preferable Main Profile encoded.
But if you want - you can continue complaining and comparing your TF with nexus or whatever you want. Thats pointless.
So the bottom line is - reencode.
You can find Handbrake profile on this forum, for example. Or try to find best acceptable settings yourself.

i think the reason why people, myself included, assumed that is because the tegra2 was being shown off as being capable of playing HD video, which, it is, but just not all hd video, and not the most common form of it, in the high profile.
i do thank you for giving a technical reason though. i had always been under the impression that the tegra is simply the most powerful out there, when i got my Gnex, that was proven very wrong.
i've been looking into the reencoding, as well as reripping. and thanks to a few good posters i have some good setups. Now just to setup my laptop and hopefully that will be powerful enough so it doesn't take 20 hours to do one movie.
Hey guys, I've been enjoying using the Shield for both Android and PC games, but being a spoiled PC gamer has left me with a desire for 60fps when streaming PC games. With my Shield connected to my wireless N router over the 5GHz band at 300mbps and excellent signal strength, would that not be enough bandwidth to stream 720p 60fps video? Is there a way to increase the framerate manually?
According to a lot of reviews I've been reading, you aren't going to get 60 FPS. I've heard 30-45 range is what is expected, depending on your connection. Since you have a great connection don't expect anything higher than 45....

that sounds right. If you had 2 different framerates i imagine you would get flashing or stuttering,

But they are at 2 different framerates. If you've got a decent computer, start streaming a game at Shield while looking at the game running on your computer. They are both definitely not at the same framerate

I do have a decent computer
ASUS P9X79 LE
Intel i7-3820
64GB RAM
NVIDIA GeForce GTX 660 x2
Don't see the need to list more then that.
As far as streaming goes you can't use the same methods for framerate that you would use on your desktop. I tried setting the resolution to 1280x720 in the game setting, had it at 1920x1080 and I noticed the framerate on the shield go up at 1280x720.

Yes, for "NVIDIA Supported" games, the resolution change is automatic. But for other games, you'll get a lot better results if you change the resolution to 720p, since that's the native panel resolution (higher res means higher bandwidth)
I've said in another thread, thinking of an idea to get controller support to work better. Stay tuned.

I'm not quite sure what you mean by that. You measure framerate the same way on any LCD. I'm aware that it is best to stream games at 720p, but I was asking if the stream could be sent to the Shield at 60 frames per second, instead of the ~30 frames per second that it currently does.

Yes that true if the LCD is connected to the computer rendering the video you see.
You can improve FPS and streamed FPS by simply changing the game settings to display at 1280x720.
Here is a simple way to find out try it for your self.

I already know changing the resolution to 720p will increase the framerate, but it does not increase the framerate that Shield is streaming at above ~30fps. Every game, no matter what framerate I get on the computer that is actually playing the game (for example, Bioshock Infinite. My pc will play that game at over 120fps on medium settings at 720p resolution), the Shield is still streaming at 30fps. What I'm asking is not if I can get better performance from my PC, I'm asking if the streaming video from my pc to Shield can be increased from 30fps to 60fps.

How do you know what the shield is playing for fps? do you have some fps counter that runs on your shield?
maybe you should look up
Video Scaling
Bandwitdh for HD Streaming

I can tell that the Shield is at around 30fps just by looking at it, the same way I can tell the difference between 24fps for movies, and 30, 60, 120fps for video games.
Video scaling has nothing to do with this, since the source is in 720p in the first place, and I guarantee that 720p at 60fps does not use more than 50mb/s

Just to correct you... 1280 * 720 * 60 * 4 = 211MB/s (uncompressed) So the real question becomes what is the compression level.
(Add the breakdown 720p = 1280 x 720 resolution, 4 bytes per pixel (32-bit color), 60fps)

Consider me corrected. What are your thoughts on the framerate?

Honestly, got no idea. I don't know if they're throttled on the PC or not. I actually imagine they would be to reduce the traffic... I can't think of a way to detect that you're getting behind on packets until it's too late and you've got game lag. It's better to error on the side of low latency... But that's just my own thoughts on trying to implement a feature like this.
Streaming Dolphin emulator I noticed that i cant run at max resolution (2560x2112) it gets laggy.(too much to stream? or low bandwith router?) when i go to 1280x1056 it streams just fine.
Same with Borderlands 2. max everything is laggy. so it must be limited to how much data it has to convert to be able to stream 720
im using 2 660ti

Assuming only 30fps, a resolution of 2560x2112 would require 618MB/s of transfer rate. I believe the stream is actually done at "native" resolution, so if you're PC is playing at 2560x2112, the data stream is 2560x2112 too. You'd need a wired gigabit to even come *close* to maintaining that type of stream.
