Using "-show_entries packet=flags" may be faster than "-show_packets".

Hi,
Thanks for the feedback. After having another look, this can actually
already be done with ffprobe. I was incorrectly using -show_frames
instead of -show_packets, causing a big performance hit.
This works well, with the same performance:
ffprobe -show_packets -print_format compact input.mkv
