I can extract "video stream" frame information using ffprobe
{{{
% ffprobe -select_streams v -show_frames -print_format json
1280x720_Shinkarenko-Gonzalez.mp4 > allframe-info.txt
}}}
But if i further add "-skip_frame nokey" to above command
{{{
% ffprobe -skip_frame nokey -select_streams v -show_frames -print_format
json 1280x720_Shinkarenko-Gonzalez.mp4 > keyframe-info.txt
}}}
It doesn't make any difference to the output. What I am trying to is
extract keyframe info. I get this data from first command. But then the
output file contains detail of all frames and I have to filter out text
file. Moreover, I feel that using skip_frame will speed up the result I
need.
