document current most important todo for jellyfin streaming

HLS + jellyfin still transcode when the container is piped via ssh like
this. I attempted to use mkclean(8) and mkvalidator(8) from Matroska
streaming project but they did not fix anything. Using ffmpeg and
skipping any additional muxing allows for the hard work to be done on a
beefier machine, and a quick 150-200x repacking to be done on the
weaker headless box.
