ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Fri Jun 24 00:58:17 2016 +0300| [82b7525173f20702a8cbc26ebedbf4b69b8fecec] | committer: Martin Storsjö
Add an OpenH264 decoder wrapper
While it is less featureful (and slower) than the built-in H264
decoder, one could potentially want to use it to take advantage
of the cisco patent license offer.

+Libav can make use of the OpenH264 library for H.264 encoding and decoding.
Go to @url{http://www.openh264.org/} and follow the instructions for
installing the library. Then pass @code{--enable-libopenh264} to configure to
enable it.
+For decoding, this library is much more limited than the built-in decoder
+in libavcodec; currently, this library lacks support for decoding B-frames
+and some other main/high profile features. (It currently only supports
+constrained baseline profile and CABAC.) Using it is mostly useful for
+testing and for taking advantage of Cisco's patent portfolio license
+(@url{http://www.openh264.org/BINARY_LICENSE.txt}).
