So, I've noticed that in Windows using just a CPU, Kodi seems to have no chance of decoding 4K HEVC at 60fps. 24fps is doable but 60fps just peaks out. Even using my overclocked six core 4930K I can't get close to 4K HEVC at 60fps to work. I hit maybe 40fps tops, often more like 30.
Meanwhile MPC-HC can manage this no problem. Maybe 40%-50% CPU load. It's totally doable. My GPU is a R9 390X, so there's zero hardware acceleration for HEVC available. As far as I understand, while they are certainly different programs, FFMPEG is what is being used at the core of both problems. I get that different software has different performance but this seems to be a MASSIVE disparity between two pieces of software using the same core decoding solution. I've achieved similar results on a 3770K and 4590, so I don't think that this is machine specific.
So I was wondering if someone could explain to me why Kodi seems to be so much less efficient at decoding HEVC using software decoding in FFMPEG?
