Thanks for the hint. Will use that.

This really only makes sense when using force_original_asp
make sure that the calculated output resolution is
divisible by n so in can be encoded with certain encoders/options if
that is required.

Best regards,

you could use volumedetect for generating waveform images.

Hi,
I had a more detailed look at this and found a way to do exactly that,
thanks for the hint. It's kind of an obvious approach if you think about
it but sometimes one is just blind ;)
I guess that makes this code/patch irrelevant for now.
One question left is, if there is any interest in having
Hi Stefano,
my first idea was to have ffmpeg generate the image but you are right,
that the unknown length is a problem. The only solution I could come up
with was to have something like a two-pass encoding so that you know
how many samples you have to deal with and in the second run generate

Hi Clément,
this is the patch I was looking for... thanks!
I've applied the patch against the current master and had a first
glimps at it. It works well. I've tried it successfully on a two minute
