[FFmpeg-user] signalstats

[Chris Davis]

In order to show specific entries with signal stats, I have used the
following.

input=[file to process]

ffprobe -f lavfi movie=$input,signalstats -show_entries
frame=pkt_pts_time:frame_tags=lavfi.signalstats.YDIF:frame_tags=lavfi.signalstats.VDIF:frame_tags=lavfi.signalstats.UDIF
-of compact=p=0:nk=1:s=',' | awk -F, '$2||$3||$4'

produces this output. pts_time, YDIF, UDIF, VDIF
