Description
Summary of the bug:
When I encode yuv422p10le video (or any >8 bit video) to ffv1 I get the warning:
[ffv1 @ 0x7fb29b050a00] bits_per_raw_sample of more than 8 needs -coder 1 currently
I can then add '-coder 1' and it will work but this performance seems inconsistent with ffmpeg. Can't '-coder 1' be the default with >8 bit video rather than requiring that it be explicitly stated.
How to reproduce:
