Boost centre channel when downmixing

Hi,

When playing a 5.1 file on 2.0 audio setup conversations are sometimes a bit hard to follow. OSMC had a great feature to deal with this; it had a feature that allowed the center audio channel to be amplified when playing a 5.1 file on a 2.0 audio setup. A nice trick to do hear conversions perfectly.

It would be great to have such feature… for ffmpeg-based solutions the required code appears to be quite simple… see https://github.com/osmc/osmc/blob/c6ce614d03a7b9c7f1519ff1be46d3de097ba3c7/package/mediacenter-osmc/patches/atv-002-boost-centre-channel.patch for some code snippets :wink:

Cheers,

Eric
