Hi all,
as a follow-up to this discussion:
https://ffmpeg.org/pipermail/ffmpeg-user/2021-March/052358.html
I would like to ask, if frame counting with ffprobe can be made faster.
The way it done now is obviously by decoding every single frame and
afterwards incrementing the counter. See how slow this example runs:
time ffprobe -count_frames -select_streams v:0 -show_entries
stream=nb_read_frames -of default=nokey=1:noprint_wrappers=1 input.mkv
I additionally like to suggest to add a short cut option for this operations (count
frames + count packets). This would also "automatically" entail a item in the
documentation, where people can find it without the need to repeat this question in the
mailing list again and again.
