I'm very new to transcode, but need something that will detect whether
or not a video I have has a silent audio track or not. I'm having
trouble making heads or tails of transcode and there isn't much for
detectsilence on google.
Here is the command I'm using:
[EMAIL PROTECTED] transcode-1.0.3]# transcode -i
/home/cyrus/Desktop/test.avi -J detectsilence
the output is mostly gibberish to me (below). Any ideas about how to
interpret this? Is it possible to get just a "true" or "false" value
about whether the audio track is silent?
