I tried the VLC nightly build for 12/01/2014 .
There is one now from 12/3/2014 but I doubt the 2 days newer will make the difference.
I also tried the one from Here
Neither will play a h.265 MKV’s if the resolution is higher than 1536x864 .
I only tested 16:9 resolutions .
The next one up 1664x936 has some frames that “gray” out & some that are fine.
Of course I started my tests with 1920x1080 1080pHD .
MPC-HC version 1.7.6Â (a6fdacc)Â (blitzkrieg)Â (master@ebc29cf) has no problem playing the h.265 MKV’s . I do have it set to use the LAV filters.
Most of the ones I tested were done with ffmpeg :
FFmpeg version: 2014-12-01 git-928322c
This build was compiled on: Dec 1 2014, at: 02:24:45
I did one with VidCoder . I couldn’t get it to use 1920x1080 for the resolution to convert to. (I later figured out how to do that but I haven’t converted one that way yet) . The resolution of the VidCoder conversion is 1920x818 . It has the same “grayed” out problem .
I suspect a 1920x1080 form VidCoder will do the same.
I like VLC & it is usually my main player .
I hope they get this fixed .
My conclusion is there is a problem with VLC with higher resolutions done with h.265.
I would think it could be my video card or Vista OS if MPC-HC also did this .
This is what the problem frames look like in VLC:
This is approxamately the same frame in MPC-HC :
