Hi,
We currently use ffmpeg to combine 2 streams (telephony codecs) into
mp3/wav/flac, etc.. This is no problem - we use:
ffmpeg -ar 8000 -y -f mulaw -i calls/example.g711a.ulaw -ar 8000 -f mulaw
-i calls/example.g711b.ulaw -filter_complex "[0:a][1:a]amerge[aout]" -map
"[aout]" output.wav
If
of
finding the appropriate curve for each video).
What we need is a solution that analyzes the video to detect when frames
are dark and then lightens only those frames. What I think we need is
something like the "pp=autolevels" filter but I haven't had much luck with
that.
Thanks,
Oliv

What is the right place to ask such a question?
I've contacted Fabrice Bellard who is listed as the copyright holder
on the licensing page, but he told me to reach out to the community as
he is no longer involved.
Best regards,

Hello,
i am experimenting with desktop video/audio capturing this is the
command i used:
ffmpeg -f alsa -ac 2 -i default -f x11grab -r 30 -s 1920x1200 -i
:0.0+1680,0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast -crf 0
-threads 0 testout.mkv
this kind of worked but the audio in the
32 matches
