Description

I use youtube-dl to get the video and audio DASH links from YouTube to play them in vlc. On some (!) videos the -f option gets only the video link for video and audio. Seems to be more frequent on newer YouTube videos.

dstftw commented 4 years ago

So what? This is expected behavior.

Isayso commented 4 years ago

That I don't get the audio link with bestaudio is expected behavior? Can you explain how to get the audio link on these videos? Thank you!

dstftw commented 4 years ago

The links are mpd manifest URL as this is fragmented DASH. No audio or video link technically exists.

Isayso commented 4 years ago

Ok, thanks, just for the background of my question, I use this function for around 2 years now in my apps, so I was wondering what happened suddenly. No idea how to go around this yet.

dstftw commented 4 years ago

Around what? Again: direct media links are only possible for media served directly, if it's served in fragments you can't get URL to media file cause there is no media file but fragments.
