I've been trying 720p HEVC with Kodi Alpha 4 with my Intel NUC (Intel Celeron N2820) running Windows 8, and it performs okay 80 % of the time, except for the complicated scenes with lots of movement in the background. In those cases it starts lagging behind with the sound, until the scenes become less complicated again, and most of the times it catches up. I also tried VLC and Mediaportal, and those play the same files without any issues, except for some frame skips. But the video is never lagging with the sound. How come the performance differs so much? Do they use patched / different codecs, or simply a different configuration?
