Using kmp 1435 and 1436 and EVR, system in sig below, video will often freeze while audio continues to play. This can happen with ALL video types but more common with high bitrate HD video, such as decrypted bluray mt2s files.
Using same config but with VMR9 renderless instead of EVR, no freezing.
Using version 1434, no freezing with EVR. However, no subtitle or pixel shader either. Using EVR CA with 1434 also results in freezing, but pixel shaders and subtitle work.
NO video freezing: EVR in 1434, VMR9 in any tested version (1434 and later)
Video freezing problem: EVR in 1435 and later, EVR CA in 1434 and later.
subtitle and pixel shaders work with EVR in 1435 and later. work with EVR CA in 1434 and later. Coincidence?
I hope this helps the devs track down this problem.
PS: since the video freezing seems more likely to happen when CPU usage is high, I tested it by running prime95 along side kmp. Sure enough, this soon causes the video to freeze with EVR. With VMR9, I may get dropped frames, and the sound may break up, but the video and sound keep playing (no freezing). When I stop prime95, with EVR, the video stays stuck; with VMR9, kmp recovers nicely and resumes playing normally, which is the way it should be.
