+ # To workaround this previously adaptive -> flash trick was used to obtain
+ # unencrypted m3u8 streams (see https://github.com/rg3/youtube-dl/issues/4118)
+ # and bypass georestrictions as well.
+ # Currently, unencrypted m3u8 playlists are (intentionally?) invalid and therefore
+ # unusable albeit can be fixed by simple string replacement (see
+ # https://github.com/rg3/youtube-dl/pull/6337)
+ # Since recent ffmpeg and avconv handle encrypted streams just fine encrypted
+ # streams are used now.
