Summary of the bug: Cuda/nvdec hwaccel outputs P016LE instead of P010LE on
10bit video.
How to reproduce:
{{{
ffmpeg -hwaccel cuda -hwaccel_output_format cuda \
-i /path/to/10bit-video -an -sn -dn -vf hwdownload,format=p010le -f null -
...
[hwdownload @ 0000020612888240] Invalid output format p010le for hwframe
download.
[Parsed_hwdownload_0 @ 00000206106e7140] Failed to configure output pad on

https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/30e6effff94c6f4310aa2db571917bb2952f4d9e
For correctness and consistency with the old behavior, a change like this
is required in the above commit:
{{{
+ } else {
+ frames_ctx->sw_format = sw_desc->comp[0].depth == 10 ?
AV_PIX_FMT_P010LE : AV_PIX_FMT_P016LE;
+ }
}}}
