Hi,
when I use
ffprobe -show_frames INPUT
I get all frames.
But I only want some frames e.g. the first 10 or frame 100 to 109.
ffprobe doesn't seem to provide anything like -ss -t or -frames. So I
assume it always probes the whole thing.
I would suggest you cut the desired frames you need for probing to a
temporary snippet.
In Korn this would look like this:
#EXAMPLE VALUES
SOURCE="Source.mp4"
START="10.00" #for 25fps frame-precise with a 0.01 seconds resolution
FRAMES="10" # for cutting ten frames beginning with the one at 10.00
seconds
PREVIEW="TEST.mp4"
# COMMANDS
ffmpeg -y -ss $START -i $SOURCE -frames $FRAMES $PREVIEW # generate
test clip
ffprobe -show_frames
$PREVIEW #probing the preview
rm $PREVIEW #to tidy up
in Korn I can catenate these lines with "&&" to a single line, so that
following commands only get executed if their predecessor(s) didn't fail.
Hope it's readable enough to translate it to your preferred coding
language.
