video black detect
Takes a video of up to 30 minutes and finds, in one pass, segments where the picture is black (blackdetect), where it freezes (freezedetect) and where the sound drops out (silencedetect), each with start, end and duration, using minimum lengths and thresholds you can set. A summary says whether the file passes with no finding longer than the limits. Leading and trailing black is reported separately because it is often intended. Runs locally with ffmpeg; nothing leaves this machine. Billing.
