Hello
ffmpeg has a very good field detection algorythm:
ffmpeg -i <INPUT_FILE> -vf idet -f rawvideo -y NUL
Output:
[Parsed_idet_0 @ 003ea220] Single frame detection: TFF:0 BFF:153
Progressive:0 Undetermined:0
[Parsed_idet_0 @ 003ea220] Multi frame detection: TFF:0 BFF:153
Progressive:0 Undetermined:0
Is it possible to extract an timestamp list where you can see on which
timeposition in the file the field order is changing?
Like this:
00:00:00.000 - 00:00:23.040 TFF
00:00:23.080 - 00:01:00.000 BFF
00:01:00.040 - 00:02:00.000 Progressive
Sometimes material is made where field orders are switching, so it would
be very helpful to find the exact time position where the field order
changes.
