Yet the same input file with the hevc_vaapi encoder works, at least with

[hevc_vaapi @ 0x55c9421756c0] No usable encoding profile found.
Error initializing output stream 0:0 -- Error while opening encoder for
output stream #0:0 - maybe incorrect parameters such as bit_rate, rate,
width or height
Conversion failed!
I 'll retest with this patch applied and see if it solves the issue.
But as things stand without the patch, hardware-based decode+encode
pipelines with specific encoders (QSV & VAAPI), as demonstrated, can be
very failure prone depending on the input file attributes.
The input file used, as reference, is encoded in the yuv444p colorspace, as
shown in the ffprobe output.
