Hi *,
ffprobe can nowadays produce JSON output, which is quite convenient
sometimes. I am trying to use that feature in order to get the output
of volumedetect as JSON. I tried the following:
ffprobe -loglevel error -of json=c=1 -show_entries root -f lavfi
-i 'movie=filename=clip.mkv:streams=a,volumedetect'
The "-show_entries root" means that all information should be included
in the JSON output, but still I cannot find anything from volumedetect
there. On the other hand, the above trick works just fine with other
filters, e.g. for cropdetect you can do
ffprobe -loglevel error -of json=c=1 -show_entries frame_tags -f
lavfi -i 'movie=filename=clip.mkv:streams=v,cropdetect'
Is there a way to make this work? Or is this a shortcoming of volumedetect?
Thanks
