I will see what happens if I disable madvr and use EVR in mpc-hc, as was suggested before.
What I don't understand is how every other app, including vlc, chokes on the 4K content, except wmp. It makes me think that some sort of hardware decoding is being done in wmp, but I have no evidence of this. The least I can do is check if the LAV video decoder is being used. Some clips are so demanding, even the TV can't play them via USB without dropping frames, and it also has built-in HEVC decoding.
I tested a couple HEVC clips in a pristine Win 8.1 system with WMC pack activated. No, WMPlay can't play video, only audio works, without adding a third-party video decoder such as LAV Video Decoder. AFAIK
, there is no video decoder that can decode HEVC (in particular 50fps clips) with a dual core processor + GTX 750 Ti without dropped frames. I tried:
- LAV Video Decoder
: Only avcodec (ffmpeg-based) supports HEVC and it requires Haswell Core i7 desktop processor for smooth playback.
- Lentoid HEVC OpenCL decoder
: Much better than avcodec, but still very CPU hungry. At least Core i5 is necessary.
- CyberLink Video Decoder (HAM)
: Similar to Lentoid.
- Microsoft DVD-DTV Video Decoder
: Does not support HEVC at all.
It is mysterious how your system with Pentium + GTX 750 Ti + WMPlayer can play Samsung_UHD_Soccer_Real_Madrid_Celta_Vigo.ts (HEVC 50fps) smoothly without dropped frames.
