Dennis Mungai (12023-04-05):
> When encoding an input stream with multiple dvbsub subtitles where all
> substreams are mapped (-via map 0 or -map 0:s), can the option -canvas_size
> be applied to individual dvbsub subtitles in the output, or is the option
> global?
> Case in point: In a 1:N transcode scenario, where a given number of
> outputs/renditions are made from a single input, and the same is applied to
> the dvbsubs, can the -canvas_size be set per dvbsub output via
> -canvas_size:s:0 1920x1080 -canvas_size:s:1 1280x720, and so on?
