 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:
 {{{
 ffmpeg -y -f lavfi -t 1 -i testsrc -pix_fmt yuv422p10le -codec:video ffv1
