Request to add a function for converting audio from stereo to mono format.
Description: in the current version of the editor there is a "stereo to mono" effect, it works like this:
- there are always two channels at the output;
- if you select «from left to right», there will be two channels with the same content at the output (the content of the left channel);
- if you install it swap channels, the channels will simply swap places.
Thus, there is currently no function of forming a single channel (mono sound) from stereo sound. Considering that MLT, on which the editor is based, allows you to form a mono (one channel) by merging two channels, it is proposed to implement the merge in the same way as calling the command mlt-melt ./left-right-stereo.mkv -consumer avformat:test.mkv ac=1
