Hi10P is s/w decoded, so asking the CPU to that as well as lanczos3 upscaling is simply too much. Either using bilinear scaling or re-encode to 8-bit so hw/GPU decoding can be used

Upscaling is done by GPU, not CPU. In theory lanczos3 (fast) should work with sw decoding too but there are issue with mesa and EGL I haven't tracked down yet. The timing is strange and OpenGL calls block where they are not supposed to block.

My other 10-bit encodes work just fine (ranging from 1280x720 to full HD @ 23.976 or 25 fps) so it seems that the high framerate is what causes the "issue" in the end. So is bilinear the only one that doesn't have any timing problems? It's the first one that works, all the higher ones shows the same amount of dropped frames.
