Hello Timo,
I tested your patch. It increases UHD HEVC 10 bits Main10 encoding
performance a lot while doing YUV420P10LE to P010LE (same level to Oliver's
original 10 bits HEVC encoding patch).
Your patch together with current FFmpeg git source, encoding performance
increase from 40-42 fps to 69-72 fps.
Just one note; encoding from YUV420P to P010LE is still slow. It will be
nice a similar patch is done for YUV420P 8bits to P010LE 10 bits
convertion. (For reason:
