Description

I watch videos from the PeerTube instances videos.lukesmith.xyz and videos.denshi.live. Approximately a month ago I was able to download and watch videos from videos.lukesmith.xyz using youtube-dl just fine, but today I tried downloading some from either PeerTube instance and youtube-dl just spits out the page's html source code instead of a video file.

Usually I use RSS/Atom and then run youtube-dl on the link provided in the feed (which appears to be different from the one available by visiting the site directly, interestingly), but both links are causing the same behavior.

For some reason ctrl-enter or some button combination I accidentally pressed submits the issue, I wasn't done editing it...

I also wanted to add that I usually use the command "youtube-dl --no-playlist -f 'bestvideo[height<=?720][fps<=?30]+bestaudio/best' $1" to download, but neither this command nor just running base youtube-dl (with or without my config to output to my Videos folder) successfully downloads the videos.

The original video was taken down, but here's a different PeerTube video and link from a different instance (videos.lukesmith.xyz) that does the same thing:

For 'https://videos.lukesmith.xyz/w/8fbf5fd7-3d52-43b4-bf0f-baf0a6355519', try https://videos.lukesmith.xyz/videos/watch/8fbf5fd7-3d52-43b4-bf0f-baf0a6355519'

These aren't instances known to the PeerTube extractor. yt-dl invokes the generic extractor, which should discover the PeerTube "incompatible browser" message and then pass the URL to the PeerTube extractor.

This doesn't happen because the PeerTube extractor routine that discovers unknown PeerTube instances expects to see URLs with '/videos/watch' (or '/videos/embed') and the RSS service that you use has started to report URLs with '/w' instead. In extractor/peertube.py, we need to change the pattern in line 486:

            r'https?://(?P<host>[^/]+)/(?:w|videos/(?:watch|embed))/(?P<id>%s)'

Then:
