youtube-dl uses rtmpdump for sites which provide an rtmp stream. If rtmpdump is not installed youtube-dl quits with an error, e.g.: $ youtube-dl 'http://www.arte.tv/guide/de/051091-031/x-enius?autoplay=1' [arte.tv:+7] 051091-031: Downloading webpage [arte.tv:+7] 051091-031: Downloading JSON metadata [download] Destination: X -enius - Wie lernt unser Gehirn-051091-031_PLUS7-D.flv ERROR: RTMP download detected but "rtmpdump" could not be run. Please install it. I think, it would be a nice solution to provide an rtmp useflag which install rtmpdump as dependency, so the user could choose whether he want it or not.

If you'd depend on a USE flag on youtube-dl to do that for you, you'd have to re-emerge youtube-dl as well for the desired effect. > I think, it would be a nice solution to provide an rtmp useflag which > install rtmpdump as dependency, so the user could choose whether he want it > or not. So you claim that /before/ you install youtube-dl, you already know you will at one point find a video that requires rtmpdump, so that when that happens, no unpleasantness ensues? I don't agree.

I don't agree. You are right, but this is not my point. Surely I emerged rtmpdump even before creating this bug, but I emerged it with "-1" because I thought, this depedency will be covered by youtube-dl. I don't want to have rtmpdump in my world file, It may take the same amount of time to set the useflag but it will prevent you from having software installed which you don't need, once you will depclean youtube-dl. Another point: If you are an admin and want to provide youtube-dl for your users, you want to make sure your installed youtube-dl has all the functionality it could have, so you activate all useflags (expecting it could then download rtmp streams like all other streams as well).
