Greetings,
This is my first post to this forum. Sorry for my bad english...
I am running XBMC VDPAU 18735 revision in Ubuntu 8.10 2.6.27-14-generic and the problem is that 24p (23.976 fps MKV's) movies aren't smooth. I am using XBMC's auto refresh property and I have a Full HD projector, whitch supports 24Hz, 50Hz and 60Hz refresh rates at 1920x1080 resolution. I am using Nvidia 185.13 beta drivers.
When I am watching 24p movies, CPU usage is only 2-4% per core, but the movement is not smooth. My 1080p MKV's occasionally judder and it is very annoying. The movement can be smooth for minute (or two), but sometimes playback slows down for short time. It looks like that movie jumps suddenly forward one or two frames. XBMC's info shows that frames aren't dropping.
When playback judders, XBMC info shows that frame rate varies between 23-25 fps. 25 fps and 29.997 fps movies playback is fine and XBMC's info shows that frame rate is stable.
I checked from projectors menu that resolution is 1920x1080@24Hz with 24p movies. I got an Intel E6600 C2D dual core prosessor and PALIT GF 8400 GS PCIE 512M DDR2 DVI HDMI VGA-card.
Without VDPAU support my processor has not enough power to play smoothly 1080p h.264 29.997 fps content.
