Database Develop

HD Video for G Tablet

I wanted to see how an HD movie plays on the G. I tired to play an Apple Quicktime HD Movie trailer and no go. I also tried to play an HD Trailer from Yahoo movies and no go, it said "download failed".
Can the rooted G with TNT 2.4 play HD Quicktime movies? What's the best way for me to test this out?

From what I have read, the g-tablet has some very specific requirements for viewing 1080p files. I know for a fact that it will play MP4 H.264 so I just encode everything to that with Total Video Converter.
I haven't tried to play a .mov yet on it. I have a couple that I downloaded from the web that I should try.
Edit:
Just tried a 1080p .mov that I downloaded from youtube. It plays in Rock Player with software decoding, but really bad.
I suggest downloading hd content to a computer and converting to mp4 h.264 because we know that is supported by the tegra hardware.

I am really disappointed with the quality of video playback on the G Tab. With everyone jiving about the great hardware specs, I don't see great video playback. Unless I don't have it maximized right.
I downloaded a couple of converters and converted movies from mov to mp4, avi, and wmv. I also used Roxio Creator 2009. Nothin greally plays all that great.
What am I missing?

The best converter for the g-tab, in my experience, is Handbrake. I use the built-in Regular-Normal profile and change h.264 to mpeg4 (because tegra 2 has issues with h.264) and it plays completely smoothly at 720p and 1080p.

It plays .mov containers - the Tron Legacy trailers come to mind.
It has some trouble with mkv's and mulitple audio tracks, and HiDef h264 videos that are encoded in "high profile". That's been my experience.

There's no video player (that I know of anyway) at the moment that is designed to take advantage of the tegra2 hardware. Once there is it will fly. The G Tab doesn't seem to support a lot of codecs as well.
I've had success playing 720p x264 MKV's up to 4GB with Rockplayer and ES Video Player.

Excellent. Thanks everyone for the input. I'll check some of these tonight.

Well that didn't take long: http://forum.xda-developers.com/showthread.php?t=881835 - Rockplayer 1.5.x (Tegra 2 optimisations)

Has anyone sucessfully played a 1080p video?
I have tried mpeg4, mkv and h.264 and they play but the sync is off and they are very choppy.
According to Nvidia's website the Tegra 2 is supposed to have an on-chip h.264 decoder and encoder on it. But nothing seem to take advantage of it. Even the new Rockplayer with the Tegra 2 Optimization.
If anyone can let me know how you encoded 1080p to play on your tab I would be greatful.
EDIT:
For anyone else looking, I got 1080p to work on mine with Rockplayer 1.51 and hardware decoding. I donwloaded a youtube/vevo 1080p video and ran it through Handbrake. Normal profile, MP4 container and MPEG encoding. It plays FULL 1080p very smooth that way.

[Q] Best Video Player is?

Been trying to find a good video player...all seem to lag quite a bit or are quite choppy...anyone have any luck with any working really good? If so, please share!

I like rockplayer. Used it for a bit on the plane yesterday.

Is there a certain resolution you encoding videos too or will rock player handle anything?

i have an android phone and I use both rockplayer and mvideoplayer. rockplayer handles avi files well but not mkv files. mvideoplayer handles both.
i don't have a nook color but I would assume if you have a rooted nook(and have access to market) you could get these players and they should work since the processing seems the same.
i'm interested in a rooted nook color but can't seem to find if anyone has actually tried these apps.

rockplayer on the nook can handle 480p non hd videos fine in the mkv or avi containers. anything higher than that and you start to get audio and video seperation because the proc cant keep the video going at the propper pace

im using mplayer on mine right now and watching some mp4 videos, not an hd file ... but the proper ratio and it looks killer ... totally worth 250 bucks

vplayer
I use Vplayer beta and i strongly recomend it. it plays most videos well and only lags a bit when you get to real high quality videos

i bought a nook color and tried it out...so far video playback is not that great.
mvideo player seems to have a very slight audio lag when i played a standard avi file(not converted or optimized for nook color) and no mkv files work on any of the players.
i think this has something to do with the internal videoplayer itself and not really the actually processing power of the nookcolor.
looks like i will have to just convert files to mp4...an extra step but I read more than watch videos.

If you are using anything other than an mp4 file extension then you're using software decoding. Software decoding will only go as smoothly as the CPU allows. I've found when using software decoding I can handle AVIs up to standard def in Rockplayer. (480) I get a tiny bit of stutter at the start, but it smooths out within 60 seconds.
However, if you use hardware decoding, (only works with mp4 files) you can probably push the resolution up a bit. I have a 720x400 file at a video bitrate of 800 that plays instantly and smoothly in the native player and in Rockplayer. I plan to go home and push the resolution a bit further and see where it starts to desync, so once I do I'll report back.
tl;dr: Anything other than mp4 has to be standard def or lower and played in a 3rd party player that can do software decoding, like Rockplayer. Anything in mp4 can be played in anything that does hardware decoding, and can probably go quite a bit higher than SD.

Playing MP4 videos on rooted NC?

I transferred several MP4 videos I shot with my G2 onto the rooted NC but they can't be played.
I'm guessing that because the NC doesn't have a camera, it's GPU may not have the hardware codec necessary to play the MP4 files.
Has anyone else had any success playing various video formats?

I had some success using rock player. I was able to load a 1024x576 mp4 video on the nc and play it in rock player. It wasn't silky smooth, but perfectly acceptable for watching. I used handbrake to rip it. I can post more details and maybe upload a sample if you'd like.

Yes, please.
Looking at bn.com it looks as though playing mp4 videos should be working out of the box...
I would appreciate a sample video and your HB settings so I can transcode some content of my own to carry around.
Thanks!

I wans't able to get the video to play with the B&N player as advertised, but that may have been because of my handbrake settings, which as promised are as follows:
Container: MP4 File
Picture: Anamorphic Loose, Width 1024 (to fit the nook)
Video Filters: All Off (shouldn't matter for playback, only for how good of quality the transfer is)
Video Codec: MPEG-4 (FFMpeg)
Framerate: 29.97
Average Bitrate: 997kbps
Audio: AAC (faac), Bitrate: 160
I have a 3MB sample here.

NC default player doesn't support video width above I think 854. You can find the exact specs in the FAQ on BN support.
Audio needs to be aac rather than mp3. To make a long story short, mp4 and m4v aren't video formats. They're containers for a video stream plus an audio stream, and there are a wide variety of video and audio stream types that can go in this container. NC default player doesn't support all of them, but the ones it does handle I've found it handles better than RockPlayer.

[Howto] Video watching on Nook Color

As you may know, the Nook color has PowerVR SGX530 Graphics chip, which is also available on Droid 2 and Droid X.
This chip is pretty good when it comes to medium 3D performance and video playback. It can play videos quite nicely, but only the formats that it knows. Other formats will need to be played using software, which will give you medicore level playback.
If you have an MP4 files (which are encoded with H.264 Base level encoding), those files will play with hardware decoding great. However, if you have other video content (episodes, both in AVI/XVid or MKV/H.264 format), Nook will play them badly with 3rd party software (rock player, vplayer, etc).
Thats where FFMPEG could help a lot, if you're using Linux, all you need to do is install ffmpeg and run the following command:
Code:
ffmpeg -y -threads 8 -i myvideo.avi -b 800k -bt 1000k -vcodec libx264 -vpre default -vpre baseline -acodec libfaac -ac 2 -ar 44100 -ab 128k mynewvideo.mp4
the "myvideo.avi" is your original AVI file, and "mynewvideo.mp4" is the new MP4 file which could be played nicely on the Nook Color. Please note: if your video is bigger then 854x480, then you need to add the -s XxY where XxY is the width:height of the video (example: 640x352). If your video needs a new aspect ratio, you can use the -aspect parameter (example: -aspect 16:9)
If you're using a mac, then handbrake is your friend, as other tools which are based on ffmpeg.
On Windows you can either install FFMPEG for Windows, or you can use An application called "Any Video converter", and simply select your original file name, Select X264 as video codec, and convert. The output file should be played well.
No matter what conversion software you use, make sure that the H.264 profile that you use is set to base-level (or "base"). Anything higher cannot be played by the nook without frame skipping.
If you want to test if your video can be played with hardware acceleration, upload your video to your Nook (or to the Micro SD card), open any file manager and click on the mp4 file. Try to play the video with the "Movies" built in app. If the app will recognize your video, it will play it without any issues or frame skipping.
Good luck
Hetz

HandBrake can be used on Windows also

I read there are aspect ratio issues with the built in player. But I also read that even in mp4 base other video players can't take advantage of the hardware playback accel (proprietary drivers). Is that correct?

Handbrake doesn't work for windows?

Handbrake works great on Windows. Encoded a few this week for the Nook and ran like buttah.

Out of curiosity, why not just use RockPlayer. I'm yet to get an NC so I may be missing something.

It runs kind of choppy on video files encoded with anything other H.264/MPEG4 and the audio seems to get out of sync quickly

It really depends how the official Froyo update (coming in January) will improve performance.

rock player works fine... the problem is that you cant have above a 480p video. the reason is its not the audio thats lagging its the video studdering and thats whats causing the lagg

The topic title should read "how to watch videos on your nook if you run Linux"
You added all the settings you need for it, but not for the other operating systems lol You can run the file through any of these programs, (speaking Mac/Win) but just because you encode it with H.264 doesn't mean its going to play smoothly. If your source file is 1080p, this obviously isn't going to work.
My source file is:
H.264
Deinterlaced
720p
30fps
VBR 1 pass
AAC. 192kbps 48kHz, Stereo
So far Im at a video file @ 1024x576 at 15fps (tried to pull the Consistent Quality slider to 100%, but didn't see much differance) thats had the smoothest playback.
Now Im pretty much brand new to video editing and making, are there any settings I could be useing to make this file more smooth using Handbreak....or even more so In Adobe Premiere?
Im basically trying to see what the highest quality the Nook can take. Not to mention a continuous video of my coral reef while Im at work sitting next to me on my NC would b kinda epic

I use DropFolders. It uses HandBrake & you set it up with a watch folder & a destination folder. All you do is drop a video in the watch folder & it converts the file & puts it in your destination folder. You set up the HandBrake arguements in Drop Folders. Works like a charm.

According to the published specs for the NC, the default app will not play video above 854x480. If you want to use hardware decoding through the default app, you'll need to scale that down from 1024.
I have several videos encoded using one of the latest nightly builds of handbrake for NC, and with the constant quality set at 20, playback is flawless. You can use the "Apple Universal" setting to get the required baseline profile for MP4 and then adjust the video size as you like.
You can also use the "High Profile" and change some settings and per HERE. I was, however, able to set the max width above 720, unlike the third poster.

Innnnnnteresting! Thank you! I will give this a shot and see what I come up with

I posted a handbrake preset here. It works well for me.

Don't worry, I found an easy way to convert videos for nook color, read the article "Nook Color Video Converter Review – easy play any video on Nook Color"
from
Code:
icamcorder.net

Got a Nook Color over the weekend, and video looks great using the Handbrake preset posted here... I'm using Autonooter, and the built in Gallery app to play it. However, I'm curious, if I decided to try out Honeycomb, will other video player apps use hardware decoding with files encoded with the Handbrake preset, or is it limited to the stock Nook app? Thanks!

[Q] Divx playback (neverending story...)

Hi!
I have been struggling with this topic for a few days now. Read most of the threads written here on this too. I know about the limitation of hardware accelleration, and understand it. I have created presets for Mediacoder (+CUDA) perfectly working so that I can quickly convert what I want to a video format being very well played by on nook with hw accelleration.
I am aware of the fact that videos encoded with xvid/divx can only be played with software decoders. It's been reported here such videos are pretty well handled by players like Rock-,Mobo-,YXplayer and so on; I assume nook's CPU has enough power not to have issues with ~620x350 XVid encoded video. Well, mine seems to have one.
I tried out a couple of different .avi's I have. Just one specific example:
an episode of some TV show:
Video: 310 MB, 1037 Kbps, 25.0 fps, 624*352 (16:9), XVID = XVID Mpeg-4
Audio: 38 MB, 130 Kbps, 48000 Hz, 2 channels, 0x55 = MPEG Layer-3
This one is being played fine even on my old PPC Axim 30 (Intel XScale PXA270 at 624MHzwith TCPMP), but with no means on the nook. Test results:
- RockPlayer -> slide show
- YXPlayer -> slide show
- YXPlayer Neon -> slide show
- MoboPlayer - almost the one. The only one which plays completely flawless video, but the sound is out of sync, about 1 sec behind the video
What am I missing/doing wrong? Such a file should be a walk in the park for a Cortex A8 at 800MHz, shoudlnt' it? Is it about me using a rooted stock nook? Would froyo did the trick?
Regards,
Maciej

So you're on stock? Have you overclocked your setup? If so do you have governor set to Interactive and the Min. Cpu set to atleast 800mhz?

Found your problem. I find that the nook can only do 24fps or 29.999999fps. You must be trying to play a European program. Re-encode in Handbrake and change the "Framerate" drop down box to the NTSC Video setting.
While you are at it, in Handbrake and all, you might as well re-encode using x264 to take advantage of the Nook's hardware decoding...

Generally? Or in terms of software divx/xvid playback? I re-encoded the file to H.264 WITHOUT changing the framerate and it works smoothly. For the hardware accel the framerate is not an issue.
I wonder what the problem could be: the sound isn't stuttering, the video is smooth, they are simply not synchronized. It cant be due to lack of power,can it?
Regards,
Maciej

The NC supports hardware decoding of MPEG4 (i.e. Divx/Xvid) Simple Profile but it has to be in a MP4 rather than AVI container. Unfortunately MP3 audio is incompatible with MP4 containers so the typical AVI needs to have at least the audio re-encoded for hardware playback on the NC.
It's not unusual to have poorly muxed AVI files where the audio and video end up out of sync when re-encoded. I'm not sure about Mediacoder but Handbrake does not easily allow adjusting the audio offset to compensate for that. You might try aviDemux (open source) as it does allow adjustment of audio offset. Unfortunately, it's trial and error to figure out the proper offset. If your Divx file is MPEG4 SP then you could just set up aviDemux to copy the video, re-encode the audio to AAC and mux in an MP4 container with the appropriate audio offset.

For me just software divx playback. My 25 fps files just never play well.
For x264 you can do any framerate up to 39 fps I think, as long as the bitrate is low enough. For me in Handbrake the magic number is a Constant quality of 22

@razmajazz
Sorry for the confusion. I have no issues with any x264 re-encoded file, as mentioned in my first post - my Mediacoder preset does its job perfectly.
I mean MoboPlayer plays the original Xvid video and audio very smoothly, they are simply out of sync, which doesn't look like a CPU power issue to me. As poofyhairguy said, it must be about the framerate and some incompability.
Re-encoding doesn't bother me, I only wanted to avoid it if possible for lower quality divx/xvid films. And the MoboPlayer seemed to be only an inch far away from the right solution.
I will do some testing in the afternoon.
Thanks,
Maciej

DSP drivers/Hardware video decoding is critical for smooth playback.
I dont know why the CPU cannot do it fast enough. (software decoding)
Thats why I'm on nookie froyo
No sync issues or anything with normal res videos from the interweb, no recoding needed, any decent MPEG4 player plays smooth.

Indeed I was confused. I thought both the original and re-encoded files had audio sync issues. As long as the video stream is MPEG4 SP, you may still just want to copy the video, re-encode the audio to AAC and mux in a MP4 container. It's pretty fast since you only have to convert the audio, you don't lose quality from re-encoding video and it plays back with hardware decoding on the NC.

Success!
Yesterday I ran nookie froyo from SD. MoboPlayer plays all files perfectly, no out of sync! It was that simple...
Thank you all for your suggestions!

Maciej
