Hi everyone.
I know, bad video performance is a known issue (see http://www.htcclassaction.org/).
But on my device I'm not able to play any video file without bucking image. About every second, the image stops for a short instance (I get sick watching this for more than a minute )
I tried different video files with different formats:
- wmv8 with 300 kbp/s, 25 images/s, 320 x 240 with wma8 128 kbit/s stereo (converted using All-in-1 mobile video convert)
- mpeg-4 (H.264)/AVC, between 128 and 1248 kbp/s 25 images/s, 320 x 240 and 64 to 128 kbp/s for stereo audio (converted with SUPER)
- a couple other files found on the web
I tried to play them with the installed Microsoft Media Player. Normally sound is ok, video never is. For the video it seems to make almost no difference what settings I use. mpeg-4 is a bit better than wma8. But between the 1248 kbp/s and the 128 kbp/s video there is no difference (besides th artifacts), It's bucking the same.
Can anyone please tell me, what codec / settings are playable on the HTC S730? Or can someone post an example video file that plays well on his device?
Any help is appreciated!
Window's media player is your problem in this case.
I have Core player and that TCPMP one posted above. If I drop resolution on some of my files I can play them perfectly in core player, and with TCPMP set to low (medium) all videos play fine. High action scenes sometimes cause a little studder so I am going to lower the origional res down a little bit.
The only problem I have run into is on some higher quality ones the phone runs out of page file memory which I currently have set to 1024 within TCPMP. Make sure your phone's memory is clear when trying to watch stuff and you should be just fine. Especially if you are dropping the resolution down that low.
I will try to take a short video of a video playing
Works!
It works! The problem really was windows media player!
Thanks a lot for the hint - I think I'd never try to change the player...
Frame rate is not perfect yet. I still have to figure out what the best settings are, but it is already ways better than before.
Hehe, no problem. WMP is not a well optimized player. For my computer and HTPC I use zoom player, it can handle 720p on a processor that really shouldnt be able to.
Video settings
Hi all.
After spending a lot of my spare time I finally found the right settings for converting videos for the HTC S730.
First I tried to convert videos to H.264/AVC and WM8. This does not produce anything you'd like to look at. Even with very low video bandwidth (200 kbit/s for video) the best I got was below 10 frames/s. With TCPMP it's a bit better than with Windows Media Player but there is no big difference.
But if works fine with the following settings:
Container : AVI
Video Codec: MPEG-4 480 kbit/s
Audio Codec: mp3 44.1 kHz stereo 128 kbit/s
For converting I use the free SUPER (http://www.erightsoft.com/SUPER.html).
This way I get close to 25 frames/s (maybe 10% are dropped).
Please note that such a video cannot be played with the Windows Media Player. (AVI is a Microsoft format, but it looks as the player doesn't like the codec.) However it plays fine on TCPMP 0.71 (from here: http://picard.exceed.hu/tcpmp/)

With my S710 (has a 200MHz TI OMAP850) I'm streaming 25fps/200kbs of my VLC server (which transcodes digital sat streams in real time). I'm using .ts container, mpeg1 vid, mp2 audio and Coreplayer as client.
I have an episode of Top Gear that I can play in TCMP at mediuam quality, its video rate is 199 / 25 fps.
WMP will only play the non tweeked files, in other words if it was compressed into any codec (xvid, divx, ogg, mkv) and other of the others WMP will not play it unless it has the codec installed. The other players (core player / TCMP) come able to read these files upon install so they work better.
With TCMP most of my files do not even have to be changed, just dump them on the sd card and with the player set to medium quality it goes right through them. Now some high action / motion scenes will cause a little lag or slow down but not much and not for long.
This is soooo ridiculous! WMP worked just fine in the older 200mhz devices! Now we have to switch to TCMP and make sure that no programs reside in memory before playing ANY videos? Ridiculous! HTC is losing a lot of faithful customers with this.
It depends on the type of file's your trying to play.
Just like WMP on the PC, it wont play anything without the codecs for them.
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
smithgood9 said:
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.

I read entire thread but I really want to know why archos 70 or 101 (with same GPU!) manages to play 720p hardware accelerated.
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.

I'm a heavy video watcher, so I naturally loaded up my Captivate with tons of videos, thrilled at the idea that I didn't need to convert them first...or so I thought.
While playback performance is superb on even HD content with subtitles, it seems that hardware acceleration will only work with files encoded at 23.976fps Playing files encoded at other framerates (like 30fps, or a few variable-framerate files) results in completely out-of-sync video and audio.
Now, I can maybe excuse lack of VFR support, since timecode implementation might not be so simple (I wouldn't know), but why can't my Captivate play videos at their correct framerates? Videos are perfectly in sync when playing in software mode (using players like VPlayer and RockBox), but performance is poor in comparison. That leaves me to re-encode a good portion of my videos using AviSynth--hours and hours of setup and encoding time--just to end up with a workable framerate for my Captivate.
I just want to make sure this isn't just an isolated issue, as I've had this problem on both my original and my replacement Captivates. Anyone think this should be fixed by Samsung in their Froyo release?
I convert lots of videos (BD and standard DVD discs) for use on my Cappy. Some I leave at 23.97, others I switch to 30fps. All play fine in both mkv, divx, mp4 and h.264 formats. I use PavTube Ultimate Video Converter as it reads BD discs, even those with copy protection (The Dark Knight, for one, as well as rental discs). Works great and the vids look stunning on my Cappy.

Hmm, interesting. The files in question are all mkv's that have framerates of 29.97 (constant framerate) or 23.976 (variable framerate). They have various resolutions and audio encoding. Every single one of them is heavily out of sync on my Captivate, even after remuxing into an mp4 container, although they play fine on my laptop. Using AviSynth and FFDshow to convert the framerate to 23.976 (constant) allows the videos to play fine on the phone.
A small bump: Another major issue I have with H.264 content seems to be seeking. Although I can't figure out whether this is caused by the video itself or the phone (since the videos always play and seek fine in VLC), the issue only seems to occur with H.264 videos in MP4 containers (not with MKV's).
The first set of videos are all MP4's made by extracting the H.264 streams from MKV's (all 23.976fps), re-encoding them at 800x450 resolution (using AviSynth and FFDshow on my desktop), and putting them into MP4 containers. The reason I converted them was to embed .ass softsubs as styled hardsubs (since styled .ass support is lacking in Android video players). Every single one of these videos will not manually seek past around 14:06 on my phone (they seek and play fine on my computer). If I seek to around 14 minutes and let the video play (or just let it play from the beginning), it will play through just fine, but attempting to seek beyond that causes ANY video player on my phone that relies on hardware acceleration to freeze (software codec players like RockBox and VPlayer will seek fine).
The second set of videos are exactly the same, except they are 640x480 resolution and they were encoded on my laptop (still using AviSynth and FFDShow). These videos will not seek past 3:25 seconds on my phone without freezing the player (once again, they play and seek fine on any computer). On top of that, these videos will NOT play through on their own: at some random point in the video (different each time), I get an error message saying "Sorry, the video cannot be played" (in any player relying on hardware acceleration), and then the video frame will freeze while the sound continues to play in the background.
Note that this only happens with MP4's: the MKV's have no problem playing or seeking, but they are out of sync if they are not at 23.976fps (constant) and I want my styled subtitles. Can anyone else reproduce issues like this? This has happened so far on TWO Captivates, whether on stock or running custom ROM's (I've used Cognition, Cezar's and Darky's with various kernels). I'm very confused and running out of ideas, I've already been asking about this on video encoding forums and haven't found a solution.
Edit: Nevermind these additional issues. I solved them by using FFmpegSource instead of DirectShowSource, now all my videos play and seek fine. However, this doesn't solve my issue with different framerates being out of sync.
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

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!
