OpenH264

The openh264 is a free software library for real-time encoding and decoding video streams. The openh264 is an open source software library for encoding and decoding real-time video streams in H.264, MPEG-4 AVC format.  It is also used in WebRTC. Although the source code for OpenH264 already existed in October 2013 and was used internally by Cisco products, Cisco did not publish its OpenH264 codec immediately. The announced reason was that they needed to separate it from dependencies on other Cisco code that is not intended to be open-sourced, confirm that it doesn't have any 0-day security vulnerabilities that could jeopardize other Cisco products using the same code, and make sure all necessary legal processes are completed.
