mpv integration does not yet work with youtube-dl

[rohieb]

When playing YouTube URLs with mpv, I only get

nordlicht: Could not open video file 'ytdl://uWbGMAPg2uk'

Is there maybe some way to get the original stream URL from mpv?

Hmm, I guess we could call youtube-dl --get-url from Lua, but then we need a way to get the YouTube video URL, not only ytdl://…

For quickly trying out things, you can use utils/youtube-nordlicht.

And for proper integration, those characters are probably the video's ID? So we could check whether the "filename" starts with "ytdl://", then replace it with "https://www.youtube.com/watch?v=", call youtube-dl --get-url on it (with a low-quality option, maybe), then plunge the result into nordlicht. :-D

This could work. YouTube URLs from playlists look like ytdl://<video-id>, but Vimeo URLs from playlists look like ytdl://https://vimeo.com/channels/bestoftheyear/169599296, and for dailymotion it's ytdl://http://www.dailymotion.com/video/x5c3xm5. When playing only a single video, the URL from the command line is the same (and I just found out that mpv can even play these ytdl:// URLs if you specify them on the command line!)

It's a bit unfortunate that the video is effectively downloaded twice, once for nordlicht and once for watching in mpv. But I cannot think of a good solution, and loading the nordlicht video in a lower quality seems like a good tradeoff.

Then we have to consider livestreams, which also have a YouTube video ID, but cannot be downloaded (for obvious reasons), or at least only after the livestream has finshed…
