Custom postprocessor arguments

[ghost]

Im working on a project that relies heavily on youtube dl to download videos from various sites and pipe the output to the user, to the browser that is, and im really missing some custom postprocessing options.

For instance, i download a youtube video and i cant pipe it to ffmpeg, because mp4 cant be piped, and the only thing that i need in this particular case is to raise/lower volume, which is a single argument for ffmpeg.

Anyway, is there a way we can pass a custom postprocessing command line, that would be an awesome feature.

Right, the reason im using stdout, and avoiding using physical files, is because the site has like 30k hits a day, which means the hdds were getting filled up pretty damn quick with physical files.

You should be able to do this with the --exec option.
