actually i don't think it is really possible. (even libvlc has removed
direct support for playlist-files; the application has to parse the
playlist and then create a "media_list_t" structure according to it,
which can be played; Gem does nothing of that kind)

otoh, m3u is a rather simple file-format; you could even try to parse
it from within Pd.

that's a tricky question: how do you loop a live-video stream?
after all [pix_video] is really an interface to infinite pix streams,
not to fixed-length media; hence you don't get information about film
length and EOS, which you need if you want to loop.
the object to play fixed-length media is [pix_film].
unfortunately, there is no VLC backend for [pix_film] so far.
luckily there is a GMERLIN-backend for pix_film, which can play a lot
of files as well.
