So far it seems like 10-bit color depth yuv422p10le is only
available for AV1 via FFmpeg encoders libaom-av1 and librav1e.<br>
That is not yet with the from experience faster libsvtav1, which
currently support pixel formats yuv420p and yuv420p10le.<br>
<br>
My AV1 (video only) test run procedure using CinGG loading a 10-bit
input file, resulted in 12% smaller file size than with h265.
Visually the AV1 output file seemingly is ok, but there are some
CinGG output "FFStream::seek I/O errors, seek fails" I don't know
what are !?<br>
