ffmpeg options: Enable trailing ? for map_channel
The -map option allows for a trailing ? so that an error is not thrown if the input stream does not exist. This capability is extended to the map_channel option. This allows a ffmpeg command not to break if an input channel does not exist, which can be of use (for instance, scripts processing audio channels with sources having unset number of audio channels).
