Hello Moritz,
I dont want to extract the Metadata from each frame.
I want to analyse the video itself, not its metadata.
In some cases the metadata will not fit to the essence picture.
And for these cases I want to analyse the essence, and print out a
"report" on which timeposition a frame has different field order to the
wanted one.
Best Regards
Christoph

Is it possible to MARK the framenumbers to its detected field orders?
Via framenumber or timestamp?
Or to search a "known" TFF content for BFF frames? To force the output
to lines like:
Found BFF frames at position X
I don't think ffmpeg provides the desired statistics, but you could
extract them yourself.
The idet filter inserts metadata into each frame as documented here:
https://ffmpeg.org/ffmpeg-filters.html#idet
You can use ffprobe to show and analyze the metadata and parse your own
conclusions:
$ ffprobe -f lavfi -i "movie=infile.avi,idet" -show_frames
and use ffprobe arguments to show only the interesting fields (frame
number, tff/bff, statistics) for the desired streams.
Thinking about it, those "cumulative" values may even be the indicators
you are looking for. (Not sure.)
Cheers,
Moritz
