Never assume the API of libav* to be stable unless at least 1 month has passed
since the last major version increase.
The last version increases were:
libavcodec: 2015-08-28
libavdevice: 2015-08-28
libavfilter: 2015-08-28
libavformat: 2015-08-28
libavresample: 2015-08-28
libswscale: 2015-08-28
libavutil: 2015-08-28
