This page contains information on the Cisco OpenH264 firefox plugin.

Background

Cisco provides a binary version of a OpenH264 plugin for firefox. This plugin is needed for WebRTC along with other H264 decoding. This binary is released under this agreement from Cisco: http://www.openh264.org/BINARY_LICENSE.txt

Upstream firefox versions download and install this plugin by default automatically. Due to it's binary nature, Fedora disables this automatic download.

Source

Source for this plugin is available at https://github.com/cisco/openh264 under a BSD license.
