My XBMC setup is at about 90% satisfaction for me, there is only ONE issue I have not been able to eliminate: an occasional frame skip with vdpau activated. If I can correct this issue I can seriously consider selling my blu-ray player!
Hardware: Athlon X2 5000+
Geforce 240 GT
Software: Ubuntu 10.04 LTS
Nvidia Drivers 260.19.29
XBMC 10.0 (not live)
So, when watching any source with vdpau enabled, 480p/720p/1080p, every so often, there will be a slight frame skip, it is hardly noticeably, but I do notice it, and it is really distracting. It is non-repeatable, that is to say, random. It does not matter if the bit-rate is really high or low. When it happens, if I jump back, it will not repeat.
I have tried enable/disable sync. It seems slightly better with sync disabled, but the problem persists. It is not a dropped frame, as when it happens, the dropped frame counter remains the same. I tend to drop no more than 10-25 frames per movie. Playback is extremely solid except for this issue.
Now, here is the odd part, if I disable vdpau, the issue goes away. All play back is flawless. The downside, my system is not powerful enough to play hi motion 1080p material without a shutter. Dropped frames rise into the 100s.
I did run a log, the only thing of note is there are some consume packet errors in the log. Other than that is looks fine. I have not check to see if this is in the log without vdpau.
I have seen other threads that speak of vdpau judder, but the posted issues seem much worse then what I am experiencing. This is like one frame, every 1-3 mins.
Any ideas?
