How about doing quick diagnosis with ffprobe before you start,
something like:
ffprobe -v error \
-print_format default=noprint_wrappers=1:nokey=1 \
-select_streams V -show_entries stream=pix_fmt
and make the command depend on the result?
Thanks for the suggestion, but that actually is what I'm doing right now
- yet it means to treat parts of the batches with different
conditions/recipes.
Additionally, in that concrete situation, the source videos (several
thousand...) are stored on an S3-type object based storage (non-Amazon
dialect). So used Mediainfo to avoid having to pull several hundred
Terabyte of videos just to get their tech-MD.
And Mediainfo cannot tell me what FFmpeg considers yuvj420p, because...
Even if it wasn't for the "S3-extra-fun", I'm running into this issue
every now and then in different video collections - and every "if - then
- else" adds extra points of failure (and work).
You see my challenge? :)
Kind regards,
Peter
