description     Digital VCR and streaming server (new unstable API/ABI libavcodec version 52)

long_description \
                FFmpeg is a complete solution to record, convert and \
                stream audio and video. It includes libavcodec, the \
                leading audio/video codec library. \
                \
                FFmpeg is currently undergoing major changes in its API/ABI in \
                libavcodec version 52. This development release reflects those \
                changes and may break applications coded to libavcodec version 51. \
                \
                For the last valid revision for libavcodec version 51 (r15261) \
                please use port ffmpeg.
