            option which extracts direct links to the h264 encoded MP4 video files.
            These files can be loaded in a custom player to allow Vimeo playback without
            triggering their dumb API domain block.

            It's a little bit hacky, but my only other option is to keep buying new
            domains every time one gets blocked.  No thanks to Vimeo, who were of no help
