[FFmpeg-user] abitscope won't run

[Mark Filipak]

Howdy,

Maybe I don't need 'abitscope'. It's just an experiment when I found that 'oscilloscope' didn't 
display audio levels.

I have a 5.1 channel DTS soundtrack. It's the only soundtrack. I want to mux in a new, 2 channel AC3 
soundtrack with soft dialog emphasized. I'm using 'loudnorm' & 'pan'.

Here's the problem: I need to measure the sound level at a particular half-second moment in order to 
set 'loudnorm's threshold. I need to do that because I can't get a linear gain that doesn't 
emphasize background sounds. Those background sounds are fainter, but they are annoying.

How would you do it?

Any advice is greatly appreciated.
