Slow video playback

Is anyone having problems with video playback?
WMV files they are played very slow (loosing a lot of frames). With MP4 I got best results but not the best. Any suggestions??
Thanks

WMV
I can't even get the above files to play

are you using Media Player? as video playback has always been awful on Medial Player on every pocket pc or smartphone ive everhad.
install TCPMP and video playback will be perfect, and will play any file you throw at it

Thanks for the tip keyz86. I'll try it.

no problem, glad to help a fellow Dimondarian

won't play
loaded the TCPMP but everytime I try and start it i get the attached error, using diamond help

Dimondarian Cool hehehe

Has anyone been able to play a full resolution file without skipping?
I am using CorePlayer now but if another player works better, please say so.
With Coreplayer I benchmark about 85%, which is not good enough.
I believe the Diamond should be able to get 100%.
I found that an encoded mp4 file would play about the same as the original avi xvid file...
What do you use to encode videos specifically for the Diamond?
Come on!! Post your results!

What video settings do you use with coreplayer ?
DirectDraw, GDI or what ?
This is what i get:
With these configs.:
But with some other videos i have i get only 88% speed and some frame drops and tearing.
Doesnt the Diamond has a good video hardware.
Imo, it shouldnt lag at all.
Ive read somewhere that it doesnt use the hardware correctly since the drivers were not fully implemented. Not sure if its true.

Still looking for a good solution... any more help?
Coreplayer is still choppy ...

Yeah, I wasn't able to get WMVs to play using this, either.

I think what we need to have a look at is which encoding, resolution, bitrate, fps, etc are optimal for the diamond using core player.
I'm experimenting a bit. Will report back in a bit...

I've just got my Ignito (diamond) a couple of days ago, but I've got a long history of video playback on hand helds. Since this is my first time post, and I happen to have a bit of time on my hands.... I'm going to convert a file into a series of different resolutions and settings to see which one will perform the best. I know the objective is to get a full res one to play, but I'll see what I can come up with.
Also, I'm using the default ROM at this time.

With Coreplayer you should use the 'QTv' display option - this is hardware accelerated and beats 100% benchmark on every AVI I have tried. If you get a blank display using this mode, you are using an old version and need to update.

Alright. After trying a bunch of different codecs, encoders, video and audio formats at various resolutions I came the conclusion that for now, full resolution video is just not possible without jerky movements during continuous motion or fast action scenes.
My eyes are very sensitive and I get really irritated if playback is not perfectly smooth.
So far what works the best in achieving this kind of natural playback is AVI as the output container with XviD video codec at 480 x 360 resolution, and mp3 audio. I set the video and audio bitrates to match whatever the source video was (min 864 kbps and max 1008 kbps for video and 192 kbps for audio).
Even then, CorePlayer is a must with the following settigns: QTv On, TytnII driver mode On and Smooth Zoom On.
Every now and again CorePlayer will show only a purple screen during playback when QTv mode on. At that point I usually do a soft reset and it starts working again.
This issue may be resolved with an upcoming release of CorePlayer (1.3) but until then, the solution above works exceptionally well.
I'd be very interested in anyone else is having success in other ways...

320 by 240 versus 640 by 480
I have done some playing with conversion and have found that the Diamond (currently) does not support the 640 by 480 settings with a good bitrate. The BEST conversion I have found (using Coreplayer to play back the files) is using the BETA Version of the Pocket Divx Encoder (http://www.pocketdivxencoder.net/EN_index.htm) and using the HTC Diamond Template (NON VGA!!!!, there is a VGA and non VGA) that team has developed. They have done an excellent job!
The output settings -
Dimensions 320 by 240
Video Quaility - "36" ... 584 kb bitrate
Hopefully an update by HTC or coreplayer will be released to fully utilize the resolution that the Diamond SHOULD be able to support, but for a clear, non jerky playback, this is my 2 cents

im able to play those axxo dvdripson using coreplayer without any sort of convertion....

I want to share my experience. I am using core player and trying to recode unprotected high-definition TV shows (original resolution of 1920x1080) that I've recorded on Windows Media Center (.dvr-ms files) to watch on my Sprint Diamond. Unfortunately .dvr-ms are poorly supported, and the only program I've found to recode is TMPGEnc 4.0 Xpress.
I am using Core Player version 1.2.5 build 4506, and my video output is QTv Display with the Tytn II driver mode enabled.
Like everyone else here, I have had horrible results when converting the shows to DivX at 640x360 at any usuable bitrate (above 500 kbps). Benchmarking in Core Player yielded a playback speed of 66% or so (completely unacceptable, obviously). So I played around with the resolution and bitrate, and finally settled on the following:
Format: DivX
resolution: 512x288 (maintains the 16:9 aspect ratio of the original)
Video bitrate: 850 kbps
Frame rate: 29.97 fps (progressive)
Audio: MP3
Audio bitrate: 80 kbps, 48kHz sample rate
With those settings, I have a 104% playback benchmark with around 25 dropped frames compared to several thousand played, and about 29.5 fps. Basically, it is completely smooth audio and video.
I was still PO'd that I had to sacrifice so much resolution and bitrate on a supposed media device, so I played around with other formats. WMV was awful. MPEG-2 was awful, and avi was passable, but no better than DivX. I also decided to try h.264 (MPEG-4 AVC). Here are the settings I used:
Video Format: MPEG-4 AVC (saves as .mp4)
Resolution: 640x360 (still maintaining the original 16:9 AR)
Video bitrate: 1000 kbps
frame rate: 29.97 fps (progressive)
Audio format: AAC
Audio bitrate: 96 kbps, 48kHz sample rate
Core Player absolutely choked on this. It was unwatchable, and the benchmark revealed a playback speed of 50%. Dropped frames were higher than played frames (!) and framerate was 13 fps. Obviously not successful.
But, before I deleted the file, on a whim I decided to try Windows Media Player and...it was completely FLAWLESS playback. Absolutely beautiful, smooth motion, no audio stuttering, slow and fast pans were the best I've ever seen on a WM device.
Why??? Is there something I'm missing about this that someone can elaborate on? Is this the fabled "hardware acceleration" that I've read so much about? I should note that WMP had a hard time on a 320x240 .wmv file, so I can't really understand how it is able to play a 640x360 .mp4 file so smoothly. In any event, I have found my perfect file format, and, surprisingly, it doesn't involve Core Player in any way.
-R

The thing is that HTC didn't release any kind of SDK for Diamond or Touch Pro and companies like CoreCodec have hard time trying to figure out how to use the HW acceleration but they are trying very hard to improve the situation so maybe with time they will be able to use the HW for now the only way we wan't to watch videos with HW acceleration is only WMP which means recoding or atleast remuxing files.
Cheers
P.S. Could you post exact specs of the .mp4 file? What kind of AVC it was and things like that.

in regards to the WMP hardware acceleration.
is it better on battery life than having coreplayer trying its hard out to render a video. even if its a small 320x vid that plays at 120%. Does that mean that the cpu is running near max?

Play 720p mkv?

Hey guys,
I was thinking about buying a Nook color but I had one question.
Will the Nook Color be able to play 720p mkv files? With subtitles? I noticed that the archos 70 can play 720p mkv files and It seems to me the cpu is similar in both units.
I am pretty uninformed about this topic so I was hoping if anyone could enlighten me? I did not want false expectations that one day someone will be able to get it to work on the Nook Color.
Btw I know that Nook Color can not play it natively, but since the archos 70 I was wondering if the Nook Color could 2 in the future?
Thanks for your help!

is there an app?
At the moment, I don't believe the nook will play .mkv files without rooting it. I haven't rooted mine yet (waiting to see if 2.2 really does come out next month and what changes it brings, first) so can't say if there is an app that will play them.
I would think that it could, as long as the necessary app is installed and the codecs are available. The hardware seems like it would be perfectly capable of playing a 720p file, no matter the format, it would just be squished down to the correct resolution of 600 (or smaller depending on ratio).

Don't know about 720p, but as long as the video and audio streams are something the NC recognizes it should play an MKV (h.264, mp4 for video, aac or mp3 for audio). Although I had much better luck with just straight up mp4 files.
The built in player only even showed subtitles if they were hardcoded to the video.

i can play 720p mp4 files just fine with no lag what so ever.. Quality is awesome.. Rock Player doesn't like MKVs or AVIs, it will play them just really really slow..

Are you using the stock player or Rock Player?

rock player plays mkv's fine on my evo but i cant get it to activate on my nook

mvideo player plays mkv 720p anime with subtitles that i have on my samsung captivate. (although it seems you have to start the video from beginning to end (ie: can't skip around) or the audio will get out of sync)
wondering if you download android market and get mvideo player if mkv 720p subtitles will work on nook color as well.
if so i would be interested in the ereader/tablet

Why? The root takes approximitly 15 to 20 minutes. Is practically completly automated, and improves the device 500%.

I loaded up a 800mb standard def AVI and it played fine in rockplayer. Bit of stutter at the start but it smooths right out after about 10 seconds. Just FYI

Nook Color can only play these video formats: 3GP, 3G2, MP4, M4V, and OGG. And supports MPEG-4 Simple Profile up to 854×480, H.263 up to 352×288, and H.264 Baseline profile up to 854×480. So if u want to enjoy video on Nook Color, u should convert video to Nook Color compatible formats. I suggest u a powerful video converter called Foxreal Video Converter, which enables convert all video formats to Nook Color with the optimized video format (MP4, 854×480, H.264 codec, 1500kbps avg bitrate, AAC 48KHz 160Kbps) to give user the best visual enjoyment.
U can try it, hopefully it can help u.

You can download an app from market and then you can watch rmvb on Nook Color. So, your post is not 100% accurate.

There are a couple apps vplayer and rockplayer that can play just about every format on armv7l (our cpu)
More importantly I heard the ffree and awesome VLC player is coming to android VERY soon, that will be the best for the NC for sure

I have tried half a dozen video apps and have been unable to play 720p mkv.

720p youtube vids don't work
I tried downloading 720p and 1080p videos from youtube with tubemate and they wouldn't play. They'd skip and stutter - totally unwatchable.
Also just tried playing a 180meg 720p AVI of the office in VPlayer. The video plays fluidly but the audio is completely out of sync.

I'm afraid 720p and 1080p are out of the question.

What's the point of 720p on a 480p device? Do you just not want to convert your video files?

Vplayer works better than rockplayer. Plays mkv. Ratings are bad because developer said application would always be free than started to charge for it. Paid version is highly rated

Because the nook's screen is 600 pixels so 720 would be the smallest "standard" size that doesn't have to be up-converted.

I play mkv files on my HTC Desire - Rockplayer and others all stuttered and displayed a blocky effect.
Then I installed Vital Player (neon) and they all player wonderfully - even 70p ones! For some reason it struggles with 720p mp4 files but who uses those?

The chip that handles video on the NC wants to play video smaller than 854x480.
Any video larger than that will not go through the hardware accelerator.
I have a thread where I attached a handbrake preset for the NC.
http://forum.xda-developers.com/showthread.php?t=992214
If you use that preset, you have to set the video size yourself (defaults to original size)
Use the original size if it is smaller than 854x480. If it is larger (like 720p would be) then set it to 854 width with "Keep Aspect Ratio" and the video file that handbrake puts out will be nook hardware accelerated.
Also, MoboPlayer is much better than the alternatives as far as the player itself goes.

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.

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!

How Nook's video capability? 720 RMVB? MP4?

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.

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.

by the way, the audio chip is awesome:
Description
The TLV320DAC3100 is a low-power, highly integrated, high-performance stereo audio DAC with 24-bit stereo playback and digital audio processing blocks.
The device integrates headphone drivers and speaker drivers. The mono speaker driver can drive loads down to 4 . The TLV320DAC3100 has a suite of built-in processing blocks for digital audio processing. The digital audio data format is programmable to work with popular audio standard protocols (I2S, left/right-justified) in master, slave, DSP, and TDM modes. Bass boost, treble, or EQ can be supported by the programmable digital signal-processing block. An on-chip PLL provides the high-speed clock needed by the digital signal-processing block.

Would someone please post the link to setting up handbrake for the best results? Would be very much appreciated!

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.
