Description

Currently youtube-dl doesn't support downloading live streams on Facebook. It only downloads .mpd file and nothing more. there is line with URL of that file: [debug] Invoking downloader on u'......', if I put it as input of ffmpeg like here:

ffmpeg -i 'https://video-waw1-1.xx.fbcdn.net/hvideo-ftw1/v/rQEjLOU4aJyavnjiCkExh/live-dash/dash-abr3/300160820720224.mpd?_nc_rl=AfBwOdAKm4i-NmXo&oh=d14993643d37bbaf767fd5155eac6f65&oe=5B5FCE97' video.mkv

then the video is streamed to a file, and after the live stream finishes, ffmpeg spams HTTP error 410 Gone to the console.

Is support for MPD livestreams planned? It seems like we already support non livestream MPDs so there shouldn't be a ton of work for this. Anyone have any tips on ripping facebook MPD livestreams? (especially since so many live streams are happening nowadays)

+1 on support for this!
