I don't understand all the details -- not by a long stretch -- but AIUI, the Cisco thing makes it possible to use H.264 for real-time video chat, called WebRTC by the W3C and "Firefox Hello" by Mozilla. Judging by Alan's USE flags, it's not available for Fx 31.x. In later versions gmp-autoupdate controls it -- with that flag set, Firefox will silently download the thing and updates to it from Cisco. Mozilla won't bundle it because it's patent-encumbered. It comes from Cisco as a binary. There's also media-plugins/gmp-openh264, which I guess means the Gentoo devs hope to offer it built from source -- I haven't looked at the ebuilds. > I have no problems playing youtube videos without it (both HTML5 and > Flash) and I don't have gstreamer enabled on firefox. That makes me worried I gave Alan a bum steer.
