Carl,
Thank you for kindly responding.
Yes, that's correct, that's what I am referring to. I have output the
MPEG-7 video signatures for a list of videos (a video database).
I then calculate the MPEG-7 video signature for a new video that I am
considering adding to that database, so that I can com

Thank you Carl Eugen,
I tried adding large values with options "-analyzeduration" and "probesize" but
this does NOT work for Closed Captions even if it works properly for regular

Please explain what "signatures (xml)" are.

Hi All,
I don't understand why neither ffmpeg nor ffprobe detect presence of closed
captions within MP4/H.264 in some video streams when VLC does.
