[FFmpeg-user] continues/periodic volume detection

[Albert Scholtalbers]

Hi there,

I found an excellent filter named: volumedetect to check the audio levels
of a file.
Is it possible with this filter to create something like a periodic
snapshot option to write the values for audio level to a file so on a
periodic basis.
If you would take an stream as input you could check if audio is still
available/or create a kind of VU meter. Very handy if you have to detect
audio levels on several recording systems.

Yours sincerely,

Albert
