#A script that checks multiple youtube and bitchute channels for new videos to download via youtube-dl
#This script works considerably faster than just giving youtube-dl a channel URI.
#The YouTube implementation now uses a YoutubeData API v3 key to work more reliably.
#This can be quite quota taxing, as each channel search is 1% of the allotted qutoa for the day.
#-> checking n YT channels => n% of daily quota required to run this script
#Keep this in mind when running it as a cronjob
#Either insert this key in plain text below at the variable "APIKEY" or do it via ENV vars or a password manager
#Since bitchute still doesn't have an API I'm using lynx to emulate a user.
#This can limit the number of recent videos available. For a whole download of bitchute channels consider other methods first.
#For youtube the videos per channel are limited to the last 500 uploaded videos. For the rest you can just use youtube-dl itself
#needed if run as cronjob
