I just installed XBMC 10, and I notice video stutter when I play H264/MKV movies.
The sound and audio sync is fine, the video just looks like it stutters.
If I play the same movies with MPC-HC, they play fine.
I used the default XBMC options, it defaulted to DXVA2 enabled.
OS is Win7 x64.
Machine is a DELL Latitude E6510 notebook, this is an Core i7 with 8GB RAM.
Monitor is 24" 1920x1200 NEC.
XBMC Dharma 10 release.
MPC-HC x64 1.4.2499.0.
Other than MPC-HC and XBMC, there are no additional codecs installed.
I used the killa.sampla.x264.mkv file to test the playback performance.
MPC-HC has no problems, defaults to DXVA enabled, video is smooth and good quality, fullscreen or windowed plays fine.
When I play the same file using XBMC, the first split second of the movie is green, then severe pixellation, then as the camera zooms out the birds start looking better, but much worse than MPC-HC.
If I disable DXVA2, the video quality is great, but lots of dropped frames.
Here are screen captures of the results:
XBMC
MPC-HC
Debug log:
XBMC
I know the pixellation problem is not the same as the stuttering problem, but I don't know how to visualize the stuttering.
Any ideas how to fix the stuttering and the pixellation?
