# Lists recently popular youtube videos by category or channels.
#
# Introduces the faux MIME type "video/youtube" for player and recording
# configuration; both utilizing `youtube-dl`. But VLC can consume Youtube
# URLs directly anyhow.
#
# For now custom channel names must be configured in the settings dialog
# text entry, and applied using Channel > Update categories..

# INTERNA
#
# The Youtube v3.0 API is quite longwinded. Here the .api() call shadows
# a few of the details.
# While .wrap3() unpacks the various variations of where the video IDs
# get hidden in the result sets.
# Google uses some quote/billing algorithm for all queries. It seems
# sufficient for Streamtuner2 for now, as the fields= JSON filter strips
# a lot of uneeded data. (Clever idea, but probably incurs more processing
# effort on Googles servers than it actually saves bandwidth, but hey..)
