I am wondering how good the Nook's video capability. It seems there is no powerful display adaper driver for it?
How about 720p video support?
Thanks
720p is probably out of the nook's hardware capabilities.
Also I believe CM7 and HC are currently without hardware acceleration. Best bet is probably Froyo, but haven't tried it.
Moboplay works well for 720p rmvb. i just used real file tested
what rom you on?
i only attempted streaming with gmote from my desktop over wifi, and regular xvid avi's were pretty choppy. (running cm7)

Your NOOkcolor supports the following video file formats: 3gp, 3g2, mp4, m4v; MPEG-4 Simple Profile up to 854x480; H.263 up to 352x288; H.264 Baseline profile up to 854x480
Your NOOKcolor will not support the following video file formats: Flash (Flv/swf); Mov/qt; AVI; MKV; Xvid/divx; WMV / VC-1; H.264 Main and High profile; and videos with a resolution higher than 854x480
So far for me, 854x480 h.264 has provided the best results, mpeg4 has more compression artifacts. There's a profile posted on here somewhere for handbrake to convert to the proper format. VLC convert and stream also transcodes to h.264 if you want to stream from a media server or PC without having to convert the files.
For it to work properly with hardware acceleration, I think only android 2.1 (stock/rooted) and 2.2 have full support.

Uh if there's audio sync issues . . . how exactly is it playing videos "perfectly" ???
As has been described already, MP4 videos encoded using H.264 baseline at a resolution at or below 854x480 work well in the stock player. Beyond that, 3rd party video players aren't performing well enough for me to accept as "perfect".
I've tried Rockplayer, Vital Player and VPlayer and none of them play raw AVI files (xvid) that I watch from EZTV to my satisfaction. The only thing that works for me is to re-encode them using Handbrake and the Handbrake preset that's available in this forum with a constant quality setting of 22.

The video part of the video plays fine. The audio part of the video does not.

Don't misunderstand me, I've done my own testing. The point I'm making is if people read such statements and then try to watch videos they'll be disappointed in the fact that there are indeed sync issues.
I'd never describe the playback of a video file with audio sync issues as "perfect". IMO the only way playback would qualify as perfect is if there are no dropped frames and no audio sync issues. That's not the case in any of the solutions i've read on these forums when it comes to AVI or MKV playback.

Nook Color's video player performance is underwhelming at the moment in regards to 720p playback. I'm no sure how the Archos 70 could play it just fine.

Okay, just to clarify concerning 720p.
Nook Color has a single-core 800mhz processor.
I have found that a single-core 1.4ghz processor is very marginal for 720p - most don't work, even with the most CPU-efficient software decoding ("core").
Generally 1.6-1.8ghz is the minimum required.
So, the only remaining question is whether the graphics chipset will actually support 720p hardware acceleration through a change in the software:
PowerVR's SGX series features pixel, vertex, and geometry shader hardware, supporting OpenGL 2.0 and DirectX 10.1 Shader Model 4.1.
The SGX GPU core is included in several popular systems-on-chips (SoC) used in many portable devices. Apple uses the A4 (manufactured by Samsung) in their iPhone 4, iPad, iPod touch, and Apple TV. Texas Instruments' OMAP 3 and 4 series SoC's are used in the Nokia N900, Sony Ericsson Vivaz, Motorola Droid/Milestone, Archos 70, and others. Samsung produces the Hummingbird SoC and use it in their Galaxy S, Galaxy Tab, Samsung Wave S8500 and Samsung Wave II S8530 devices.
Intel uses the SGX 535 as its GMA 500 and GMA 600 integrated graphics for their Atom platform.

Are there manual settings that I can program into Baddaboom? I use that for video encoding as it supports CUDA on my graphics card reducing encode times up to 70% at times.
FWIW "Saving Private Ryan" as both an avi and mp4 have played just fine on my rooted NC (Rockplayer).

In handbrake, the iPod/iPhone profiles produce video files which work fine on the NC (up to 854x480). So if Baddaboom has profiles for those devices, give those a shot. If you want try to tweak the settings manually, the magic configuration in handbrake is:
Set max B-frames to zero
Turn off CABAC entropy coding
Turn off 8x8 transform
Turn off weighted P-frames
In my experience vitalplayer neon plays movies better that rock player.

THANK YOU for that! I've been using rockplayer and having a couple different problems which put me trying different encoding methods last night (different sizes/audio settings, etc, etc.)
Rockplayer is simply inferior to the V7 "Neon" version of MoboPlayer. Very excited about this software find! Thanks!
On the 720p resolution thing:
The Nook's display is 1024x600. 720p video is 1280x720. Playing 720p format videos is overkill. You can convert it down to a smaller size (working on the "best" settings right now in my "Things I Learned" thread.)
Apparently the hardware accelleration only works on up to 854X480 MAX. Anything less than this is scaled up/down to that before run through a hardware scaling up to fullscreen (1024x600).
I find for software playing (for now) 854 width is doable, but 720 width (480p) is nearly the same quality. I'm still playing with the settings, and with the discovery of MoboPlayer, I'm redoing research. I'll be updating my thread with the "best" settings the software player can handle (max 1ghz cpu overclock). Since I'm using a max of 858x480, it should play with hardware accel flawlessly once that is working on CM7 (already works on 2.1/2.2?).
Love this platform.
Hi there!
I have gotten to new Lg Optimus 2x now for about a week and I am getting a bit annoyed now. I bought it purely on Being able to play full HD Movies on my Tv. But with countless hours spent on forums and trying with different players, and also differnt types of formats.
What I have on the phone now is QQplayer and arcmedia and ofcourse Lg's player
Formats I have used and there display quality:
.AVI Works in QQ, Arc but not in LG's
.Xvid Works in all
.Mkv (480p) Works in QQ ,Arc but not LG's Also this is where the framerate goes down.... out of sync audio.
.Mkv (720p) Just awfull
I am now converting a 720p movie to mp4 format h.264 to try if that works but it takes ages and I can't be botherd to convert a movie for 4h when I want to watch it on my TV.
So what can be done.. why can it play back some lame teasers on full hd but not a bloody movie in decent quality on 480p...
What should I try to convert movies and episodes to?(prefix)
The phone is not Rooted and I have no experience in that matter
Kind regards!

Because a video is not just a video
Video consist of 3 parts
videopart encoded to some specific format (xvid, divx, mpeg-4, h264, mpeg-2) etc
audiopart encoded to some specific format (mp3, ac3, dts) etc.
a container (avi, mp4, mkv) etc. that encapsulates the video and audio part
furthermore the video and audio part are not just encoded in specific formats, but according to specific settings - often called profiles. These define things like bitrate, b-frames, ref.frames, and other technical stuff
The chipset only support hardware acceleration (which is needed to play video in high resolution) for certain types of formats, and only when encoded after certain specifications, and only when encapsulated in certain containers, and finally only when being played by the LG player.
Other players cannot utilize the hardware acceleration but rely on software filters like ffmpeg, these give you the possibility to play formats that are not supported by the chip itself or by LG's player by using these software filters. But this also means there are no hardware acceleration to help the playback and therefore you can only play these in standard resolution and/or you can get synch issues between video/audio.
the main format supported by the chip and the LG player is called mpeg-4/h264 - and its only supported inside an mp4 container - mkv are not supported.
The encoding of the video part mpeg-4/h264 are only supported up to a certain profile level - meaning it only support upto a certain bitrate, a certain number of ref.frames, of b-frames etc. It also only support certain audio formats, mainly aac. It wont play your downloaded 720p/1080p mkv with ac3 or dts audio, and a videotrack using h264 profile level H4.1 or more with lots of ref.frames
In short you cannot just throw any downloaded or home cooked video to the mobile and expect it play - it wont. Secondly if you bought it to be a generic HD mediaplayer for these types of videofiles, then you bought it for the wrong reasons. It is not a generic HD mediaplayer, its a mobile phone, with the ability to record and play up to fullHD video - if these comply to the specifications which are supported. This videoability are mainly targeted at recording video of reasonable quality (for a mobile phone) and playing web2 content like youtube HD video which complies to these standards.
Nothing more - it wasnt designed to be your HD mediaplayer replacement
So what to do ?
make sure youre videos are encoded as h264 using max profile level 3.1 and max 10mbps bitrate - using an AAC audiotrack and encapsulated in an .mp4 container. Then they will play in HD resolution.
Now all you need is reading a couple of hundreds websites and guides on how to check your files for these specifications (mediainfo), remux video from an mkv container to an mp4 container if the video and audio inside are allready compliant, or how to reencode to desired specifications if they are not compliant.
Very usefull mini guide into the jungle of video/audio, codec, splitters and containers.
Knowing this makes it easy to setup DVDFab and other rippers/converters (hopefully).
Thanks
I tested some h264 formats on the LG2x. Baseline profile works fine for 1080p video, I tried that up to 10mbit/s. Main profile works, but is too slow on 1080p and I think 720p also. It might work with SD resolutions, but I didn't test this. High profile simply isn't even recognized by the LG media player. I did try all profile levels, it ate all of them. Perhaps someone else can figure out the maximum bitrate the device will play smoothly, and what the "maximum" resolution for the main profile is (and at what bitrate).
So if you're putting h264 HD material on there, put it in an mp4 container with AAC audio, and use the baseline profile. 10mbit/s worked fine for the 1080p source I tested with (Looney Tunes Short Fur of Flying).

Hi all
Read this guide "How to make videos to Optimus 2x using Handbrake"

Hi.. THX that is great help.. Very interesting.... .
Do you think that we can expect some 3rd party video player using hardware acceleration of Tegra 2 in Market soon.? Playing .mkv and other HD formats.? Or it is not possible.?
I do not know, but if Tegra 2 will be used in other phones than Optimus 2x ... drivers might be upgraded to support more video types.

RAWrrrRRR!! WHY?? Okay, I kinda get it thanks...
Its a fact that HW acceleration can only be used when/if Nvidia Tegra 2 drivers supports it.
But any app can play any format if it have the right SW decoder (using CPU).
Optimus 2x should be fast enough to play quality video (DVD resolution 720×576) using sole SW decoders

As I said ... "Isn´t Full HD on a mobilephone a total overkill and kind of waste?"
FAT32 SD card can't handle files > 2GB
Maby you could split files and maby Android supports filessystems other than FAT16 and FAT32 ... I don't know
I think it is not a overkill. I don't have any way of getting HD content on my TV (BlueRay, Playstation, etc) so i can sure use this.
Or when I travel I can just plug my phone to the TV in the hotel room and watch the movie.

I agree. This phone has the specs to run it, & space is up to the owner to use. I remember a headline from Engadget stating that the "the 2X has a crazy amount of codecs for video media" when it's released in S. Korea. .mkv is probably the most popular container for HD videos- disappointing the 2X does not support this...

How is it possible to play 1080X1920 on a 480x800 screen?
It might be possible to use 1080X1920 when using HDMI mirror, but then how much space do you have on your phone? And do you want to split files > 2GB?
OK ... if you use hard compression file size drops ... but then quality also drops to something that you can compare with DVD resolution!
What I ment was that I personally prefare a lower resolution in a good quality
DVD resolution 720×576 ajusted to my phone (MPEG4) take up about 1-2GB and I use to have around 6-8 good movies on my 16GB SD card.
I too hope that more formats will be supported ... at the moment its just not good enough ...
optimus 2x supports baseline profile 4.1
basically it means that most of the 720p media files you'll find in the internet won't play smoothly because they are encoded according to high profile or even have been encoded after specifically more quality wise settings
if you need to encode for 2x you basically need software such as handbrake, set on the iphone and ipod touch profile on the right and change the resolution to your preference up to 1920 width and then set the bitrate so that the maximum won't go over 20Mbit
basically avg 15 would be fine though because of the fat32 limitations 4 gigabytes, it would be wise to calculate the bitrate according to the maximum file size
i do not know if Android supports ExtFat, which supports much higher filesizes, but because of the baseline profile limitations it doesn't really make any real difference between 1080p 15kbit/s or 5kbit/s video stream nor does those additional settings in Handbrake software
there is no "almost lossless" settings for optimus 2x, only thing matters is the speed for reencoding the bloody internet
can you guys tell me some good settings to work on the nook? and what do you guys use to convert videos?
P.S. I have already seen the "Nook Color preset for Handbrake" and it said it would take over 4 hours to convert it!

Depending on resolution.
For low def videos on my OC kernel at 1.1Ghz, I can use moboplayer with software decoding without any issues with my AVI files.
(no need for conversion).
Not with 720p videos... They will need to be converted and using handbrake, I can achieve around real time or about 1.5x real time. (2 hr video will encode in about 1 1/2 hours) Just que them up and go to sleep.

thanks for the info! so avi files dont need to be converted?
Encoding time depends on the source vs output somewhat, but normally it takes anywhere from 1/2 to 1:1 the time length of the video to encode, regardless of the encoding software (I've used Handbrake, DVD Catalyst 4, Videodub(mod), and a handful of others over the years).
My solution for this is just to batch queue a bunch of files to be re-encoded and do the encoding overnight when I'm sleeping
My settings (for any encoder, but I'll put them in order for Handbrake here):
Container: MP4 file, Ipod 5G support
Picture:
1. If source > 854x480 then set Width: 854, Anamorphic: Loose, Modulus: 16.
2. If source < 854x480 and the bitrate of the original file is high, can upvert to higher res, otherwise same settings.
3. If source< 854x480 and the bitrate of the original file is low, encode at the original resolution with the same settings as 1.
Video Filters: None
Video Codec: H.264
Framerate: Generally same as source, if you have issues force to 24 (or 23.976)
Regarding 1-pass vs 2-pass encoding, see below
Quality/Bitrates:
(Here's the tricky part for quality issues)
For high-action lots of changes animation / non-animated video I prefer:
1. - average bitrate of 1500 kbps
a) 2-pass encoding if I'm concerned about overall quality (I usually batch jobs overnight when I'm sleeping). *Caveat: This will increase encoding time to ~2x versus ~1:1*
b) 1-pass encoding if I'm in a hurry, it's good enough for many videos
For things that don't require a lot of movement and have large areas of flat color, like say, South Park*:
2. - (constant) RF:20 resulting in 1/2 the file size of the bitrate used in 1.
**** Out of all the parts of encoding a video, this is your most subjective part. If you want to find a sweet spot for yourself I would suggest setting the encoder to encode a small section of a sample video and play around with these settings to find what you like best. This is what works best for me ****
Caveat: RF:0 (lossless H.264) videos will not work on your Nook Color without resorting to software decoding, which currently does not work anywhere near as well or smoothly as hardware decoding. You will most likely get video stutter, audio desync, and other issues (plus the default movies android player won't play them at all.)
Audio:
- Source: Choose your desired (language) track.
- Audio codec: AAC encoding
- Mixdown: Stereo or your choice. Dolby Pro Logic II works fine on the Nook as well.
- Samplerate: Downsample the usual 48k to 44.1. 48k with high bitrates can cause issues on NC.
- Bitrate: 128 if you want to save space, 160 otherwise.
- DRC: 0
Subtitles:
- If you don't watch foreign language (that you don't speak) videos, you don't need to be concerned with this section.
In-depth explanation of subtitling in Handbrake: https://trac.handbrake.fr/wiki/Subtitles
1. Select the correct subtitle track, if it's included in the original file.
1a. If not, find and select the subtitle file (usually a .srt) to include as a track. Make sure this SRT is actually meant for the (original) video that you are encoding, or you will have desync issues with audio / video
2. The default video player in CM7 doesn't seem to support soft subs, and many players do not (Mobo is one that does but only for selective formats). If you find one that does and care about soft (can be turned on and off) subbing, then ignore 2a.
2a. Burned In is checked on. This hard-writes the subtitles track onto the actual images so they become part of the video. This means you cannot turn them off. This might be an issue if you decide to watch the video on a larger screen, e.g., 1080p tv (jagged edges from being upverted) , but why you would want to watch a low res non-HD video encoded for the Nook on there is beyond me
Forced Only and Default are not checked.
2b. If soft subbing, don't enable Burned In. Regarding Forced Only see the Handbrake guide linked above.
3. Handbrake specific: Click on Add to make sure it's actually added as a track to your encoding.
Chapters:
If you want to be able to move around your video the way you can on a regular DVD (divided into sections that you can >> to rather than manually dragging the bar), you can enable chapter markers. This may or may not be supported on your choice of video app for Android. What this also does is force the extension (.xyz) to change from .mp4 to m4v, which (in short) is the correct nomenclature anyway but we're used to the .mp4 extension thanks to Apple.
If your player is having issues with the m4v extension, keep Chapter Markers unchecked (also make sure that Handbrake is set to name the file as .mp4).
Advanced: (Handbrake) Leave as is.
Hope this helps. Let me know if you have any questions

It depends on the AVI file. If the bitrate is too high or the resolution is above the maximum that the Nook supports (854x480), or both, your video app may attempt to play it in software decoding mode, which at the moment isn't very good.

1a. If not, find and select the subtitle file (usually a .srt) to include as a track. Make sure this SRT is actually meant for the (original) video that you are encoding, or you will have desync issues with audio / video
2. The default video player in CM7 doesn't seem to support soft subs, neither does either of my preferred video player apps (mobo and vitalplayer neon). If you find one that does and care about soft (can be turned on and off) subbing, then ignore 2a.
2a. Burned In is checked on. This hard-writes the subtitles track onto the actual images so they become part of the video. This means you cannot turn them off. This might be an issue if you decide to watch the video on a larger screen, e.g., 1080p tv (jagged edges from being upverted) , but why you would want to watch a low res non-HD video encoded for the Nook on there is beyond me
Forced Only and Default are not checked.
2b. If soft subbing, don't enable Burned In. Regarding Forced Only see the Handbrake guide linked above.
3. Handbrake specific: Click on Add to make sure it's actually added as a track to your encoding.
Chapters:
If you want to be able to move around your video the way you can on a regular DVD (divided into sections that you can >> to rather than manually dragging the bar), you can enable chapter markers. This may or may not be supported on your choice of video app for Android. What this also does is force the extension (.xyz) to change from .mp4 to m4v, which (in short) is the correct nomenclature anyway but we're used to the .mp4 extension thanks to Apple.
If your player is having issues with the m4v extension, keep Chapter Markers unchecked (also make sure that Handbrake is set to name the file as .mp4).
Advanced: (Handbrake) Leave as is.
Hope this helps. Let me know if you have any questions

wow man thanks for the amazing info, i will try these out!
To add to this, I'm watching a 1-pass, 1500 kbps average bitrate (44.1/AAC/160kbps audio) hard subbed movie at the moment and tbqh I'm not sure if it's even worth it to 2-pass encode --- if you're really anal about any artifacting you may want to 2-pass, but for me it's not worth the extra time to encode unless I'm batching up for the night. To give you an idea of the size/time ratio, one minute of encoded video with these settings is ~12MB/min.
25 min episode: 300MB
2 hour movie: 1.44GB
If this is unacceptably large, I would suggest trying RF:20 fixed bitrate (which is roughly 1/2 the size) to see if you don't mind the occasionally visible artifacting.
Also, Mobo player doesn't seem to want to expand the videos edge-to-edge, but VitalPlayer and the default movie player both do. Unless I'm doing something wrong with Mobo, which is a possibility since I use VitalPlayer Neon the most. <-- never mind, I had clicked something in Mobo that prevented it from doing so initially, but they actually do display edge-to-edge by default.

It depends on the AVI file. If the bitrate is too high or the resolution is above the maximum that the Nook supports (854x480), or both, your video app may attempt to play it in software decoding mode, which at the moment isn't very good.

Using Moboplayer (free) software decoding, I have no issue watching 704x400 AVI(xvid with mp3 audio). No skipped frames. Total bitrate of 1.3mbits (including audio I believe).
Like I mentioned, I am using OC kernel at 1.1GHz though.
i used tool to converter my videos to mp4, h.264, 854*480 for playing on nook color, all are ok. i can play in full screen with high quality.
i also tried handbrake, and i think it is difficult to use, which takes me a lot of time to import my video.
Will we have tegra2 hdmi 1080p mkv h.264 bd-rip hardware decoding?
our o2x doesn't support NEON and therefore isn't great at decoding video. it is as important as MMX was in the Pentium 1 days, it seems!

I thought NEON abandoned coz nvidia states h.264 support in h/w, while neon instruction set helps to decode video in s/w. Gurus will correct me.

maybe. but so far nobody has been able to smootly play full 720p mkvs properly, which seems to work on the tablets with tegra2 that do support NEON. so why is that different?
flash 10.3 also uses neon since the last update. see changes for new version.

probably new Tegra (Kal-El) series with NEON instruction sets from ARM and 1080p H.264 High Profile video decode
but according to this link : http://en.wikipedia.org/wiki/Nvidia_Tegra
all current tablets uses the same chip without NEON... again correct me if I'm wrong.
You're correct, there is not one tegra 2 chip with NEON. But the tablet or whatnot that can play 720p mkv probably have a player that supports MKV decode on hardware (gpu). The O2X can't handle mkv with the in-built player, and thats the only one with HW-acceleration, as of yet. Hopefully there will soon be one, or if we can port from the SGS2 with tegra (i9103).
Mkv is just a container format. These days mkv videos usually contain h.264 avc video just as .mp4 videos do, and .mp4 videos can be played back smoothly up to 1080p resolution (however just with base profile).
NEON is indeed an expanded set of processor instructions, and Tegra2 does not support it.
However, NEON is only of use if you do the decoding on the CPU in software.
Since most video will be decoded in hardware on tegra2 devices, Nvidia chose to leave out the NEON instruction, since those need a lot of space on the chip.
However it is true that the next generation tegra 3 chip (which actually has a quad core cpu) should support the NEON instruction set, which helps speeding up handling some features in software.
However, since it is my understanding that Nvidia also plans to improve hardware video decoding on tegra 3 so it should support h.264 main or even high profile 1080p videos, it is not of the upmost importance.
Hardware decoding is more efficient (and thus will save battery life) than using NEON. So whenever having the choice, go for hardware decoding...
The reasony why high resolution .mkv files cannot be played fluently is just because the standard video player does not yet support the .mkv format, and only the standard video player supports using the hardware video decoding feature.
What actually happens when you play back a video file is that the software reads and understands the container format, which contains a raw video and audio stream. The player software then handse the video off to the hardware so it can do the decoding. The audio is also decoded - common formats possibly also in hardware.
The player controls the decoding and then feeds the decoded video to the screen and the audio to the speakers.
The standard player just does not understand the .mkv container format and thus cannot reach the embedded h.264 video.
So when you use another player that does suppot .mkv then it will usually do the decoding in software, which cannot do it fast enough for high resolution videos.
However, there is great news on this!
A new update is due to arrive soon, probably until the end of the month that will include support for mkv videos, and thus mkv can be played in hardware..
This update is already available in in korea for their version LG-SU660, and judging from this post from LG:
http://www.facebook.com/pages/LG-Optimus-Speed/192477164116791
those improvements will also come to the european P990 version.
See here a thread about the improvements of the korean version:
http://www.facebook.com/pages/LG-Optimus-Speed/192477164116791
Just to be sure, i'll provide them here again:
Faster internet browsing
Support .mkv
Hardware support for 720p h.264 4.1hp
60 frame xvid works
Little bit better LG home
Little bit faster for everything.
Apparently this also includes an improvement of the use of the tegra2 hardware to also allow high profile 720p video (before it just supported low profile). This 4.1hp video is for instance used on youtube, if my information is correct...
So to answer your original question:
You will be able to play back high resolution h.264 mkv files.
However, it will probably not be able to play all of them, because the tegra2 hardware only supports the base profile for 1080p.
So it actually depends on how the rip was made.
You can already make bd rips in 1080p that will play fine on a tegra 2 device.
For instance, if you use handbrake to encode videos, choose the MP4 container format and H.264 (x264) as video codec, and in the advanced tab in the text field, enter this line:
ref=2:bframes=0:subq=7:mixed-refs=0:weightb=0:8x8dct=0:cabac=0:weightp=0:me=umh:trellis=0:cqm=flat
This will create a video in base profile that should play fine on a tegra 2.
(Please note that some settings in that line are optimized for quality, not encoding speed. You can for instance alter the subq parameter to a lower value such as 6 and remove the me_umh option, which will result in faster encoding but worse quality).
This ofcourse requires you to have/own the bluray to create such a copy.
You are on your own for anything else...
Btw, i did not take part in the survey since the correct answer is more complex than just yes or no and ticking individual boxes.
I hope my O2X can play. T_T
So...does Tegra 2 now smoothly play 1080p h.264????
Man, what do you do for living? Tanks for all this clear technical exposé!

So which p990 Fimrware enables 4.1 Hi Profile H264?
Please point me to which firmware enables 720P Hi Profile 4.1 H264 for the P990 model.
I also wana know which firmware or APP can decode h.264 Hiprofile 1080p MTS videos smoothly.
I have tried mxplaer, diceplayer or p990 media player but none of them could decode it right. Is there any way to decode it?

just convert you movies like this also work with 1080p^
that's the problem I have to reconvert 720p files already with high profile but different encoding settings = fake hd decoding of this chip
My stock V10D plays 720/1080p h264 mkv just fine!
I do have to convert some video to a lower profile in order to play them but right now I can play
H.264 mkv in profile [email protected], 1920x1080 at 27fps fine no problem!
Average filesize for such a movie is 4-6 GB, 720p @30fps runs fine as well.
I mean they released this "amazing chipset with dual core capabilities bla bla" and they can't even handle common 720p files but the sgx540 released 1y earlier can

Hello everyone,
I'm new here, I don't know nothing about what you are all talking about here ^^ BUT a friend told me that the new update allow the O2X to play MKV files > Is that true ? He told me trough an email.
I happy with the version I have right now and if it supports mkv with the new update, I will definitely install it.
Thanks for reading me.
I think we could always do it with certain programmes because the mobile can process it. But according to wikipedia, 4.0 reproduces mkv natively so yes, it should.

Hi friend,
Yes the latest V30a ICS update allows MKV format to play on native video player app.Also flv video format is also supported by the native video player.Checked on my O2x.Just that 1080pi full HD videos are not supported yet.So have fun watching vids or movies without the inconvenience of converting

:good: for the flv, my friend didn't know that
The O2X has been able to play MKV's since Gingerbread...but only to a low profile level. MKV's downloaded (tv shows etc) are all 720p HIGH Profile and the phone could not support that as the Tegra chip couldnt handle the HIGH profile.
Are you saying that our phones can now play 720p HIGH profile MKV's...because, if it can, I may actually update!

i try using mxplayer, with 720p High profile @L4.1 still the video lags and not smooth using s/w decoder. i think with handheld, it can't play mkv with high profile. only use low profile and it's playback smoothly
Thanks to Ncyde47 on another thread here...a much better explanation....
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..

Friend,
As you said that O2x was able to play MKV video format since GB but in a low profile level.But after the O2x was updated to latest V30a ICS upgrade the native video player app is supporting more formats and can play 720p high profile MKV video formats.I tried to play 720p BRRIP x264 dual audio.mkv movie and it played smoothly, without any audio delay as experienced in GB.Only problem that i faced with native video player was that i was unable to select the preferred audio language in dual audio mkv file as there is no option to select audio language.Other wise native video player is superb:good:.
Thread moved. Please post all question threads here in Q&A in future where they belong.
Thanks
AvRS
that is great to know. love mkv.
L3.1 can be called High profile yet and O2x can handle it with 720p. sometimes i find some video that physicaly gets over phone posibilities. its played with HW decoder and its not very smooth.
if you want to made 1080p videos, use handbrake and set the settings with tegra decoding possibility manual. But i dont know if something changed with ICS, but i was not able mount SD card with other FS than fat32 and there is not posible to have file with more size than 4GB and its not enough for 1080p movie in low profile

You attached thumbnail indicates that what you were sucessfully watching was indeed an MKV file (a 720p rip) but it does not indicate the profile of the file.
Most downloaded high definition MKV video files, especially tv shows, are MKV files (at 720p) encoded to HIGH profile level 4.0 or above. In Gingerbread these files would not play unless they were converted to mp4 at a lower profile than HIGH (I used BASELINE). This is a limitation of the Tegra 2 chipset in the phone.
Your Cloverfield file is an MKV, but I strongly suspect that the profile of the file is lower than HIGH (the file size is too small for a high definition, HIGH profile encoded movie with that runtime)
Sadly, im still not convinced the phone will play an MKV high definition file encoded at HIGH Profile 4.0 or above. And I dont intend to risk upgrading to ICS (with all the problems that could bring) to find out.
However, I would love to be proved wrong....
