Silence detection

[jac1d]

Hello all,

I'm curious whether there is any feature in vlc that would allow me to detect silence or very low audio levels on the input stream?

I have a watchdog process that is monitoring the stream and if there are X seconds of silence I want to raise an alarm, as the input source should not ever be silent.

This may not be a vlc function. I'm flexible and would welcome all linux command line options, vlc or otherwise. Ideally I'd like to do it in-line from a multicast stream, but I'm not picky, I could write it out to disk and compare files as well.

Any suggestions appreciated.

In principle, it could be done as an audio_filter, but this is not implemented to the best of my knowledge.
