Standard AVCHD m2ts files play with glitches

Hi,

Footage taken with my Panasonic SD900 plays with jerky and with glitches. The m2ts files however were created with Sony Vegas and are the product of encoding, so there is no relationship anymore with the raw footage. To be sure I muxed the files again using TSMuxer but the result is exactly the same.

The files play on any other compatibel device or software: VLS media player, Media Player Classic, Popcorn Hour, PS3 (if renamed mpg), ... I am on the last release of XBMC: Eden 11.0 beta 3. I think there is definitely a codec problem in XBMC here. I can upload a file if required. Who can help?

Regards

No-one has info?

No-one has this problem and no-one takes an interest? Is a media center not supposed to play home movies? Strange...

Well, I did another test, this time with Corel Video Studio X5. This program can both smart render and encode. The output of the smart render process cannot be played well either however the behaviour is different. The movies play well untill the first transition to the next clip (the place where the video was trimmed). From that point on the video hangs and starts jumping a frame forward and backward.

Again, the output plays well on VLC Media player etc. Not in XBMC.

Am I wasting my time here asking for help?

Not enough info for any of us to offer solution-

Hardware- cpu, gpu, etc
software- OS, driver, etc

Sounds like messed up video, but if VLC plays it (which is based on ffmpeg) then XBMC might do better at now that the latest ffmpeg version has been merged into master. However you'll need to build it yourself or wait for nightlies to resume as the merge was held off until after Eden, and has just happened.

Video is certainly not messed up, besides I can create 2 different kinds of problematic behaviour with the same footage depending on the way I edited and processed the video. I now found out that the raw footage straight from the camera plays fine.

Hardware:

CPU: Intel Core 2 Quad Q9450 @ 2.66Ghz
GPU: Nvidea Geforce 9600 GS

Software:

Windows Vista SP2 64 bit
GPU Driver: I tried the very latest GeForce 9600 GS Driver v.296.10 WHQL

I am in the process of testing before I migrate from my current Popcorn Hour solution to a PC based XBMC which is why I installed the latest drivers etc. It is here that I came across the seemingly problematic support of AVCHD files. I rolled back to the original version of the GPU driver just to make sure that the driver update was not causing this problem. The version of the GPU driver does not seem to affect the problem.

debug logs and sample files will help to understand the issue.

@streamerke-

You can try these simple configurations-

1. Set power option in W7 control panel to "high performance"- make a full use of your powerful Q9450
2. Enable DXVA2 using DXVA render method and disable everything else in XBMC settings/videos/playback

Hi,

I enabled DXVA2, in fact I did it earlier as a test showed that some high bitrate HD movies were played with some judder. After enabling DXVA2 everything is as smooth as can be. After all my testing is done I will reinstall my system to be used as media center. Then I need to install the latest Nvidea drivers. I already tested them. The problem reported here is a bit better but not much. I rolled back to the old version of the driver.

Anyway, I created a debug log and I uploaded test footage. The link is here for everyone to download: http://wtrns.fr/nJOJgAAg1PCddqZ


I hope this problem gets solved. This is the only showstopper left. I have experimented with Handbrake to convert the home movies that do not play well in XBMC but the result is not the same quality. I will continue testing in that area as well but I sure hope that one day I can just play my home movies in XBMC.

Have you select DXVA as Render Method instead of Auto? Have you set power option in W7 control panel to "high performance"?
