HTC S730 Video playback

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.

Choppy video playback on HTC 730

Any video clip I play in TCPMP and Coreplayer is choppy. The audio is fine, but the video is terrible, varying between about 4 and 0.4 fps.
Is this a known issue? Are there any settings I can tweak to get acceptable video playback quality on this device?

Wow thats bad, in TCPMP do you have the video quality set to high? Also you can increase your buffer size to help with playback. What programs are you running in the background also eating up memory? Are you storing the files on the phone or on the storage card?
TCMP wont play quarter mapped pixels so I have core player which "sort of" playes those files, I have not tweeked that one as much sicne TCPMP workes so well for most of my files but as is it will hang every few seconds for about a second.

I'm taking care to kill any programs in the background with task manager, the video files are stored on a microSD card. Video quality is set to normal. All TCPMP settings are left at their default values.

Here's the media info from TCPMP
Video: MPEG-4 Video
COodec: CoreASP
Video Size: 576x432
Frame Rate: 25.0
Audio: MP3
Codec: CoreMP3
Format 48000 hHz stereo
Data bit rate: 132 kbit/s
Played Frames: 225
Dropped: 199
Played FPS: 2.8

Okay, definately up your buffer size, mine is set to 4096 and audio preload at 512. I also uploaded the underrun buffer. When I get home I can type out all my settings, I can play resolutions around 352h x 640w and 704w x 400h(un changed files) at medium quality with only slight choppies in high speed scenes with lots going on.
You might also change the Video output mode to "Raw Frame Buffer"
It can handle really good video playback just gotta tweek it to fit your phone

I changed my settings to:
Buffer size: 4096
Audio preload: 512
underrun buffer: 85%
Video output: Raw Frame Buffer
And playback is now perfectly smooth, thanks! Are there any further tweaks I should apply?

Not many more for performance until HTC beef up the driver's. However you can go through the rest of the pages and tweek the audio, color's and such to improove how it looks.
Glad its working now though

How does this play on the TD2?

Hey, I'm not getting my TD2 before mid-June, but I'd like to encode some videos beforehand. Since I don't have a device to test them on I'd really appreciate if someone could download this clip and test it on your phone.
Video is h.264 and audio is AAC. I heard only WMP supports hardware acceleration, but if you have Coreplayer also I'd like to hear some results from there as well. Video bitrate is only 750 kbit/s, as I wasn't sure how high a bitrate the TD2 could handle. For some reason the motion isn't completely smooth the first 10 seconds or so, but never mind that.
The file:
http://rapidshare.com/files/238242088/750.zip.html
There is a 10 download limit on rapidshare, so I'd appreciate it if only people that intend to help me downloads it
edit: I know there is an "HTC Touch HD encoder"-program, but it produces absolutely horrible video quality at the same bitrates

I saw it on my D2, and I have to say it didn`t go so smooth as I expected.
When there is a lot of action on the screen the phone can`t keep up with the video. I presume the quality is to high for the phone.

Okay, thanks
Guess I'll have to wait until I get my phone then so I can tweak the encoding settings :/

hi i have the same question about video play
here is the same video from rapidshare for more than 10 times

I tried it and it just showed a solid green colour for the entire video. I guess I don't have the right codec or something. I don't have CorePlayer though.

I had the same green screen using the htc default .mp4 player on my TD2, but the file did play with The Core Player....the video stuttered quite badly in places and the audio went out of sync..I transcoded a movie using Touch HD Video converter see thread:

This movie runs very well on the default player with no stutter or sync problems.

Videos don't work on WMP

Guys help me ....
Everytime i want to play a Video with WMP it says "The source filter for the file could not be loaded.". I tried the blackstone encoder which has worked yesterday, when i converted 720p Avatar trailer. But i want to convert an other video, but WMP doesn't play them.
I tried several formats, codecs and bitrates. This damn thing won't work
CorePlayer plays most of the Videos, but lacks video acceleration.
ROM: Valkyrie Firestorm 5.4.23517

coreplayer dude, its the best video player around, with core player what acceleration do you need???
no need to convert avi at 720p with coreplayer, i use all of axxo movies with core player and they show with no video/audio lags, issues or interruptions, and they perform just as good as my dvd player
make sure all ur apps are closed before watching a video for best performance
IMO, windows media player on pocketpc is a joke and is the worst thing on a device, either M$ need to start incorporating codecs or start selling codecs to make it an ultimate media player, i dont even waste time trying to watch a video with WMP

Video specs
Length: 09:45 min.
Size: 62448 kb
Resolution: 800x480
Container: MP4
Video Codec: H.264/AVC
Audio Codec: AAC LC
Video Bitrate: 768 kbps
Audio Bitrate: 96 kbps
Framerate: 25 FPS
H.264 Profile: Baseline 1.3
This video doesn't work on WMP.
And its choppy on CorePlayer 1.3.6.
So what should i do?

try making it divX rather then H.264

It's better with divx but still a little choppy. Any special settings in coreplayer?

A couple of roms I've used had this problem, something with the codec being unavaliable. Just change the rom and you can watch the video on WMP

Just did a hardreset, now it's working.

[APP] DicePlayer 1.1.0

We update DicePlayer to 1.1.0
Dice Player is HW Accelerated Media player.
Desire HD/Nexus S/Galaxy S2/Galaxy S can play 720p MKV/AVI ( H.264 High Profile+AC3/DTS/FLAC Audio ) files.
Spec.
* Supported file format : AVI , MP4 , AVI
* Supported Video Codec : MPEG-4 ASP / H.264
* Supported Audio Codec : MP3/AAC/AC3/DTS/FLAC/VORBIS
* Supported Subtitle format : SMI / SRT
smoother playback for AVI(XVID+MP3) files
DesireHD can play 720p.(with 2.3 update)
Nexus S plays 720p clip well. ( flac / dts / ac3 codec )
i'll work for mkv embedded sutitles.(currently not supported)

My favorite app.
Thanks.

ok. we'll add font size option to next update.

I've got a concern, when playing a couple .avi files DICE player is stuttering, while moboplayer isn't, this is using software decoding in the latter, why is this? Shouldn't HW decoding be faster?

1.1.0 update solve that AVI Shutter problem.

Just installed and tried 1.1.0, still not as smooth as mobo, for example: when the camera is moved in any direction, there will be stutter.

could you give me information about that avi files?

I sure could:
1325 kbps
704x400
If you want any other information, just say so.

Hey, the player still can't handle the FLAC audio quite too well yet and one of my AAC audio files causes the player to crash. Here's some information:
-Video File 1-
Width: 1280
Height: 720
FPS: 23.97
Video Codec: h.264
Audio Codec: FLAC, 5.1 (L R C LFE Ls Rs)
Audio Bitrate: 48000
Audio Channel Count: 6
Data Size: 2.49 gb
-Video File 2-
Width: 1280
Height: 720
FPS: 23.98
Video Codec: h.264
Audio Codec: AAC, 5.1 (C L R Ls Rs LFE)
Audio Bitrate: 48000
Audio Channel Count: Not sure
Data Size: 2.16 gb
Also, when I tried playing a file with an AAC codec it caused an error stating "W/AACDecoder( 856): AAC decoder returned error 30, substituting silence". I attached a logcat if you want to look at it.

AAC codec is not our code. it is google's codec.
we can fix it to change system aac decoder to ffmpeg's aac decoder.

We finally fix avi XVID problem.
check update.

Doesn't work on the Nexus Sense ROM, may not be something big at the moments, but when all the quirks are figured out a lot more are going to use it.
Anyway, when you say you've fixed the problem do you imply you're going to update the player in the near future, or was that included in 1.1.0? If that's the case, it isn't fixed, since the presence of the stuttering became clear as soon as the camera was moved in any angle.

Some user use astro file manager + astro cifs plug-in + windows sharing ( in pc )
or
install apache or something in your pc
share your movie folder to web. you can play them through browser.
open internet browser -> go to your pc -> click the mkv/mp4 link.

the problem is mpeg-4 hw codec in nexus s don't support AVI sytle B-frame.
so some tricks are needed.
our 2.3.4 stock rom works well. (with DicePlayer 1.1.0 Version code 14 May 26 release )
if you use moded rom. tell me exact version of your rom.
