Ok, I've noticed that on stock 1.5 my videos looked a little bit better for some reason. On all 2.1 roms I've tried, my videos get some pretty horrible banding issues around the dark colors. I've tried re-encoding them, I've tried different apps, I've even tried decoding again off the dvds at the highest settings I can find just to try to keep the quality at a somewhat decent level. I'm pretty sure that I'm not nuts that it was way better on 1.5.
Has anyone noticed this? If not, what programs and options are you using?
I'm not talking about small videos, these are full length movies.
Here's a small tutorial of how I encode for the Fresh ROM 2.1d. I capture from a Hauppauge HD-PVR 1212 to .TS, then recode with Handbrake to a bit limit of ~500kbps and play the videos using Meridian.

Despite the crappy video I posted on youtube at the bottom of the page, full length movies play great! Much better with the 2.1 ROM (verses the 1.5 ROM IMHO). This is usually my Ace in the hand when it comes to comparing phones. I have reviewed all of my movies (animations and live action) and I haven't witnessed any artifacts or banding. But, the overall image could be improved... My guess is it would take a nice OLED screen and then power to run it at 800X600.
I was able to play a 2gb+ 720p flawlessly from my 4gb Kingston thumb drive. AVI using Moboplayer.
The Good
Gotta love widgets
Love the USB port
I did a little side-by-side with the StevePad...
Small font in a web page is easier to read than on iPad2 (my girlfriend's)
The back camera takes better pictures than iPad
The Bad
Picture colours are a little washed next to iPad
The cross-hatch pixel pattern can be seen on white backgrounds, not so much on the iPad
GUI still not as smooth as iPad...but close
The Ugly
GPS takes forever to lock - some workarounds
No ad-hoc networks allowed - but there's a fix for that
Activesync not supported, or OWA via native browser (or Dolphin) but Firefox works
I love the Iconia but Honeycomb could be a little more polished. Can't wait for updates cuz I want to keep this tab.
Hope the great developers here stick with this model for a bit.
EDIT: I traded my A500 in for another and no more cross-hatch pixel pattern!!
i had a 4GB or so mkv that a played from USB via mobiplayer. It made me use software to decode hence very choppy. 720p. Just a silly test to see what would happen. Love the USB.
As far as video codecs, all Tegra 2 devices are cursed with poor codec support, thus poor hardware acceleration support. Nvidia talks a lot of media smack, but does not support the chipset to back it up.
as of the title showed, i've experienced poor performance in playing flash movie on website. this circumstances usually comes with some flv providers such as youtube, or youku.com.
it feels like the flv movies are very lag, some of which are barely noticeable but most of them are in this condition, which likes playing "powerpoint"(though, not that serious, but laggy).
and, some of which have a resolution below 480p are in very poor quality. it looks like the whole image was created by many tiny mosaic, not smooth at all. but movies above 480p are normal, but still can see some noticeable "dots matrix" or crossing line on the movie.
i've tried both flash 10.1 and 10.3, and 10.3 is slightly better. i've also tried official rom and custom roms like lite'ning and cognition, they are the same. and different browsers, such as dolphin(which even worse compare to google's).
has anyone in this forum got the same situation?
or any clues?
i heard that flash 10.3 has worse performance than 10.1 in some devices, but with dual-core 1.2g cpu, i don't think gs2 has no capable of handling the flash stuff.
ps:now im using cognition rom with tegrak build24 kernel, tried using setcpu to 120400 and profile of performance, same as before.
Ive searched for various recommended settings and tried the ones from this thread:
http://forum.xda-developers.com/showthread.php?t=1060825
And, for the most part, the videos are fine but what gets me is in situations where the camera is panning there is a noticeable jitter to the movement. Its consistent. Its only happening on the TF. I can play the encoded MP4s/M4Vs in VLC on the laptop and no jitter.
Id really love to get rid of this, it kind of kills the experience of watching videos because I like to watch shows like Top Gear on it and they pan a lot like that, although it does impact other shows. Its just more noticeable because it only happens when the entire camera is panning around subjects in way that most of the image on the screen is moving.
Im playing in the gallery BTW.
Hi,
this is a well known problem with the google libaries for hardware decoding. Until we get a update, there are only two solutions:
Use software decoding. Apps like Rockplayer, Moboplayer... have this option.
Use a Flash-Player. There is no stuttering with the flash libaries.
Does software decoding drain more battery?
And upcoming HB3.2 is supposed to improve hardware decoding of video files ...

I hope because I have not had good luck with rock/mobo and HD content. Right now playing with the stock gallery is the best option I have seen. I was just hoping maybe there is something I could do to drop the compression or quality (without sacrificing HD) to get rid of this odd jitter.
Its a shame too because its the only thing that lets down the media experience. I have had multiple people interrrupt me on the plane to ask about it the screen is that good (well, than and after seeing me snap my netbook in half and put it back together ). Heck, even ipad guys have complimented how things look on it (and their screen uses the same tech IIRC).
I builded a very simple html site in the last few days which has the jwplayer flash player. This is the best way to watch hd content with less than 29,xx fps without the stuttering. Maybe i will put it online later today.
If you want to hard telecine the material you can remove most of the judder.
It's an unfortunate side effect of the GPU decoding that we haven't yet pinned down.

Is there any way to load MKV files with JWPlayer without naming them and their location in HTML? I'd prefer a browse option myself. Otherwise it's pretty useless to me.
I tried using Handbrake to encode to "Apple TV 2" preset. which is basically 720p in mp4 file type. It plays back very smoothly with rockplayer lite, mVideoplayer or moboplayer.

That's actually a great preset for this device. It's mpeg4 AVC High profile at a reasonable quality.
Good choice if you don't know a lot about how Handbrake works.

actually its not smooth at all, there's still a minor lag which is obvious to my eyes..so far even with the very latest 3.1 update (the one with the new tegra bootup logo), the lag is still there..i am hoping 3.2 would address this...it sucks that you cant really play 1080p or even 720p smoothly

You're either doing it wrong (possible) or confusing judder for 'smoothness'. Files encoded at sane bitrates play back fine in 720p and are completely smooth. Unfortunately, as described by sontin earlier in this thread, there is some poor telecining going on in the hardware decoding and panning shots tend to create the effect of judder which can be somewhat distracting.
It's unfortunately probably a result of the lack of a NEON MPE core in the Tegra 2 chip that causes this.
But for the record, judder ≠ lack of smooth playback.

well i guess you're right, its a judder then, but if that's the case, is there any way to solve it? i want a perfect playback like what i get on a pc
I do feel though that playback has improved considerably with the last update. I have downloaded some files that were encoded specifically for the Apple TV and other such devices. Basically mp4 with [email protected] encoding with bitrates around 3000 kbps and stereo AAC sound. Before this update, every now and again they would freeze for five seconds or so, especially in high action scenes. Now they seem much smoother. Judder is still there, but it's definitely watchable.

Nothing to do with telecine. It only occurs when there is audio in the file. Mux a video with no soundfile embedded and it plays buttery smooth. Something occurs when sound is added which causes a weird juddering effect. It's been suggested it's hardware acceleration not being enabled causing it but I'm not so sure. Jitter can happen when the audio framerate does not match up with the video framerate to the refresh rate of the display or somesuch (Not sure on the technicalities). It's why tools like ReClock are used on PC's.
I can only repeat what i said a few times: The only way to get nearly smooth playback with hardware decoding is using a flash player. There is no other solution.
And there is a positive sideeffect: Using the browser filesystem (file:///) makes video streaming over the network more useable than using a file manager app. Even over HTTP (thx to drivedav and co) it's much better.

yes, you're right. with jwplayer it works perfectly, smooth and no judder!
Interesting
for those of you that are interest!
This is what i have decided to do and its quite amazing results for its purpose!
Previously i had ben encoding mp4's with x264, @ 1280x544 or 600 whatever the video wanted to strech too, i was finding amazing quality even at fullscreen! I was amazinly happy with respectable file sizes
The dark knight 2.3gb
Saving private ryan 3.5gb
Quantam of solice 2.6 CB
However, after my huge success! I wanted to accomplish more! I need more videos on my transformer! I felt ripped off, i could not put more videos then what i had becuasw of the file sizes!
After some trial and error i found an amazing discovery but it comes with some sacrifice,
Let me talk about the file sizes first!
The dark knight 1.1gb
Saving private ryan 1.6gb
Quantam of solice 1.2gb
The hangover 880mb
Some of my movies are under 1 gb wow
I have 27 movies on my sdcard alone! Which is great!
Ok so this is how i managed such small files with mp4,x264. First off i started my encodes by dropping the resoltion from 1280 to 800 and then letting handbreak decide how to strech it
800x544 is what it normally looks like, the quality is set to 21! This is an inferior resolution for filesize with mp4! In some cases 60% filesize drop!!
This comes with a small drawback! I run my videos in the stock player anyways, so they will not be fullscreen movies! Myself i dont mind the bars on top and bottom!
If this bothers you, then this discovery is not for you!!
MKV FANS!!
STOP!! , before you start to lecture me, about mkv ,doing higher res, with 500mb encode's ! just stop!
I undersand, and know how as well , but its not supported properly right now ,and thats not what im discussing
I hope someone finds this useful
Thanks
I don't want to reencode anything. I just want it to play my existing MKV's without juddering. How do I use file:///??? to play my existing MKV's with the Flash player?

Where can you get jwplayer - I looked in the market place and found what I am quite sure was not the tool that you meant...
As movies/films is one of the main tasks this device will have in my possession I want to make sure I will not run into disappointment owners of first Tegra 2 tablets run into.
So... Atom + this SGX... mkv 720p - OK?
How about BR rips in 1080p?
I got some clips (Full HD) from may handycam in m2ts format - will they work?
It's been a week or two since I tried. I remember being pretty disappointed with 1080p and some 720p videos. I'll load a few videos with VLC, Zoom, and KMPlayer and see how well it plays.
Off hand what I remember is mostly disappointment with 1080p videos, those that played, seemed to be dropping frames and have a slight jittery feel to them. Other higher bit rate videos would pixelate during some scenes.
I have some 720p MKV Anime subs and I think the mostly played okay, but might have had some minor frame dropping. I'll have to check them out again, my memory is a little faded now. I was disappointed, but it's not Tegra 2 bad, but not Tegra 3 good either.
I have a samsung ativ with atom.1080p mkv even at 40mps play very good. All you need is enabling dxva with mpc and haali media splitter or lava filters. Then the cpu will not go above 30-40%

Just saw new video and audio drivers today for the 500T. Just installed those, so really curious now if there is going to be some improvement when I test tonight.
Ugh, new video drivers didn't help. In fact it has gotten worse, not much. But in the high bit rate 1080p video I had tested before, I'm seeing it freeze up (it didn't do that before) and pixelate in more scenes. And the 720p MKV videos, the audio is slightly out of sync.
I think it's a mix between drivers and hardware. I dunno of the SGX545 is up to the task of doing 1080p or 720p MKVs smoothly.
If you guys remember video files used as test for Tegra 2 devices we were talking about I am just uploading them to my Dropbox.
Once they are that I will share the link so you can test your Atom W8 devices and report back.
OK?
Not to mention quite different opinion between you guys (gaetanolip & Ravynmagi)

Mine is not an opinion. In oorder to play 1080p level 4.1 at 40 mbs you have to enable hardware acceleration. I just did explain how , if you guys are not capable to do so please do not complain how new atom is not enough to play 1080p (h264)videos because new atom fully CAN.
This is the proof ( older atom but same gpu even at lower mhz than my ativ ). I followed the guide ( even if I used newer lav splitters instead of haali media splitters )

I can easily play birds 40 mbs , very high bitrate

And let us know how is it handling them...
mate, GPU hardware acceleration will play it, ive had some insanely high bit rate videos playing on much older hardware, but as has already been mentioned you need to have a player that supports DXVA 1/2. MPC-HC will do it just fine, personally I use shark007 codecs that gets WMP doing the same thing (I prefer that because it allows me to use WMC to play videos as well)
On my old PC with Windows 8 but higher power than Atom I got k-lite pack of codecs and I am using WMP.
Does it mean that for W8 I should be using different (better?) codec pack like those Shark007 you mentioned?
Perhaps I would put less strain on my current HW?
Did I get it right?
look at it this way, if you try play a high bit rate HD video and your CPU usage is a sustained 80-100% then your not using hardware acceleration. Its been a while since I used k-lite as from my experience in the past it was full of crap you simply didn't need, Shark007 is about as lean and efficient as you can get. if you use MPC-HC you should see DVXA at the bottom left corner of the screen when in window mode.
if you are using hardware acceleration then id expect CPU usage to be around 5-20%
back in the day a 3Ghz P4 wasn't able to play high bit rate HD content by its self without dropping frames, THAT is what GPU hardware acceleration can bring
if you are going to use Shark make sure you delete ALL codecs you've installed before attempting to install it, most codec issues are conflicts
