Heute wollte ich mir ein informatives Video der New York Times herunterladen, in welchem die Entdeckung von Gravitationswellen erläutert wird: Gravitational Waves Detected, Confirming Einstein’s Theory
Leider wird das Video gestreamt und kann nicht wie früher als komplettes MP4 heruntergeladen werden.
Mit Safaris Develop > Show Page Resources Menu war es mir dann aber rasch möglich, im Ordner „Other“ den Aufruf einer m3u8-Videoplaylist zu beobachten:
Bewaffnet mit dieser URL und der Unterstützung des geliebten ffmpeg konnte ich dann das Video streamen und im MP4-Format ablegen:
$ ffmpeg -i "http://vp.nyt.com/video/2016/02/13/38248_1_out-there-g-waves_wg_hls/master.m3u8" -strict -2 video.mp4
