I don't understand all the details -- not by a long stretch -- but |
13 |
AIUI, the Cisco thing makes it possible to use H.264 for real-time |
14 |
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 |
17 |
versions gmp-autoupdate controls it -- with that flag set, Firefox |
18 |
will silently download the thing and updates to it from Cisco. Mozilla |
19 |
won't bundle it because it's patent-encumbered. It comes from Cisco as |
20 |
a binary. |

There's also media-plugins/gmp-openh264, which I guess means the Gentoo |
23 |
devs hope to offer it built from source -- I haven't looked at the |
24 |
ebuilds. |

That makes me worried I gave Alan a bum steer. |
