Silence channel detection

Postby schnorginator » 30 Mar 2009 01:21

Hi,

Is there any way to detect silent audio channels with the use of libVLC?

I have some bogus video/audio files (avi, mkv, ogm, etc) which have mostly AC3 audio streams with 6 channels.
The problem ist they only have 2 channels which contain actual audio data,
the other channels are just silent.

I need a way to detect that.
