# Extract material from recordings made inside BigBlueButton
# BigBlueButton records multiple videos :
# - speaker speech & webcam
# - screesharing
# for slides, annotations, etc. the playback app typically renders them on the fly upon playback
# so it may not be easy to capture that with youtube-dl
# - webcams feed : sound & webcam views : useful for extracting sound
# - deskshare captures : screensharing, but not the slides
# Extract a merged video, without the slides with
# youtube-dl --merge-output-format mkv -f slides+speaker "https://mybbb.example.com/playback/presentation/2.0/playback.html?meetingId=12345679a50a715e8d6dc692df996dceb8d788f8-1234566973639"
# For slides, annotations, polls and other stuff displayed to the
# audience the playback app typically renders them on the fly upon
# playback (SVG) so it may not be easy to capture that with youtube-dl
# To extract a merged video, which will miss the slides and webcam views, proceed with :
# youtube-dl --merge-output-format mkv -f deskshare+webcams "https://mybbb.example.com/playback/presentation/2.0/playback.html?meetingId=12345679a50a715e8d6dc692df996dceb8d788f8-1234566973639"
