Ok, I've been able to reproduce two important issues with my Windows 10 HTPC. One of these is the slide show after ~ 1 hour of playback. I was able to create a log for that myself, and it appears to be my fault, and I hope to have it fixed in the next build. However, the other issue is unlikely to be my fault:
I've played two full 3D movies now with the new glitch handling and I've found that in both movies while they start playing fine, at some point suddenly there appears to be a 1 frame (or more) delay between left and right eyes, which looks rather weird. Due to the way madVR handles stereo frames this is very unlikely to be my fault. I could imagine this to be a bug in either the NVidia GPU drivers, the Intel Media SDK, the LAV Video Decoder or the LAV Splitter.
@Hendrik, what are you thoughts on the matter? Do you see a chance there could be a bug in LAV Splitter or Decoder which could cause a 1 frame desync between left and right eye? FWIW, it occurred 3 times for me, and a seek reliably fixed the issue all 3 times for me. Due to a seek fixing the issue I'm doubtful that this would be NVidia's fault, but I can't be sure, it's still possible. Do you have any ideas how to track down which component (NVidia, Intel, LAV Splitter, LAV Decoder, madVR) might be responsible for this problem?
