Is there anything in ffmpeg or ffprobe that will, for every frame in a
single VOB (or preferably, all VOBs in an entire TS:
'VTS_xx_1.VOB'+'VTS_xx_2.VOB'+'VTS_xx_3.VOB'+...), list the following?
Assuming you have already found a filter which creates these metadata
values (like idet in your previous thread), add the metadata filter to
your filter chain:
$ ffmpeg -i input -vf filter1,metadata=mode=print -f null -
The metadata filter also has options to filter the output by key name,
and to dump its output to file (or pipe:1, for that matter).
I assume that the words in your suggested command line are all
replaceable tokens because in the filters documentation
(https://ffmpeg.org/ffmpeg-bitstream-filters.html)...
"filter1" not found.
".metadata" not found.
"mode" not found.
"print" not found.
The closest I can find is "2.20 mpeg2_metadata" and that appears to be a
metadata writer. Am I simply looking in the wrong place?
It sure would be nice if ffmpeg documentation had a search function.
I'd tried google advanced search of 'https://ffmpeg.org' for a variety
of metadata parameter names and got links to source code
(ffmpeg.org/doxygen) but not links to documentation.
Could you give me a push?
UPDATE
Based on this:
'https://ffmpeg.org/ffmpeg-filters.html', section 16.11 metadata, ametadata
I tried this:
ffmpeg G:\VIDEO_TS\VTS_02_2.VOB metadata=mode=print
and failed.
UPDATE
I've tried about 20 forms of command. The latest was this:
ffmpeg -i G:\VIDEO_TS\VTS_02_2.VOB -vf
mpeg2,metadata=mode=print:file=foo.txt -f NUL
Nothing but failures.
