<pantomime> Oh, no, it shouldn't! </pantomime> Many YouTube videos work perfectly fine without rtmpdump. This should be a USE flag or left to the user's discretion. It's really not hard to see what needs installing if a video does need rtmpdump - the error message in the opening comment is quite clear.

Works for me. It isn't obvious which version of youtube-dl you were using, so perhaps this has been fixed in a newer version. Adding a USE flag goes against a Gentoo development principle: do not add USE flags only to pull in runtime dependencies (RDEPEND="foo? ( cat/misc-bar )"). If users insist I could add a "helpful" pkg_postinst() { elog ""; } message to reflect the optional use of rtmpdump...

I'll respond here instead of underneath bug #639028 comment #3 as that's a duplicate. (In reply to Jeroen Roovers from comment #2) You should really read that comment, deso@. It gives useful objections to the USE flag proposal. > If users insist I could add a "helpful" pkg_postinst() { elog ""; } > message to reflect the optional use of rtmpdump... commit f283834fafa5b322de69aff78a853846cb1aa3d6 Author: Jeroen Roovers <jer@gentoo.org> Date: Mon Dec 4 00:51:45 2017 +0100 net-misc/youtube-dl: Version bump. Package-Manager: Portage-2.3.16, Repoman-2.3.6 That commit (landing in net-misc/youtube-dl-2017.12.02) added the friendly message.

( cat/misc-bar > )"). To expand on that a bit. What I say is `emerge rtmpdump` fixes your problem. What you say is echo net-misc/youtube-dl rtmp >> /etc/portage/profile/package.use emerge youtube-dl fixes your problem. In the process, you do the equivalent of `emerge rtmdump` but you also pointlessly re-emerge youtube-dl which was already installed (or you would not have had the problem in the first place). Why do you think it helps to make the process more convoluted? Because it gives you a nice and cosy logical link between how you like one package to work with another? I can understand that it does, as it makes me feel better, too, but I still don't think that is the right technical solution. That is a problem that should be fixed elsewhere (look for earlier suggestions on the gentoo-dev@ mailing list under "EAPI 5+: split PDEPEND introducing SDEPEND" in 2012 and under "Suggested packages option in portage" in 2013).
