#
# Browser for PeerTube instances (configurable in settings) and
# video categories. Even loads video snapshots as favicons, hencewhy
# the display is slightly stretched in comparison to radio channels.
#
# The chosen main server has some influence over sorting, but usually
# includes entries from peered instances.
#
# Currently there's no player for PeerTube /embed/ links, so the
# video/youtube MIME should be combined with `youtuble-dl` even
# for VLC. Else just use the [Station] homepage for the web view.
#
# Per default fetches 200 entries (not conf.max_streams), because
# it's a little slower on some servers. And the standard sorting
# is publication time (newest videos atop).

# The /embed/ section of the url can sometimes be substituted with:

#  · /static/streaming-playlists/hls/UUID/master.m3u8
#  · /static/webseed/UUID.mp4
# Though that's sometimes blocked / or not consistently supported on all instances.
