====== Transcode support ======

Prompted by the suggestion of //Phil Grundig// I might be adding ''transcode'' as a capturer in the future.

He also provided examples:

Frame extraction:
    $ transcode -o thumb  -y jpg,null -i somevideo.mpg -c 0-1,299-300
Will take frames 1 and 300 as jpegs



Frame extraction with size reduction:
    $ transcode -r 5 -o thumb  -y jpg,null -i somevideo.mpg -c 0-1,299-300
''-r'' reduces size, e.g. ''-r 5'' reduces size one-fifth.
