description     FFmpeg is a complete solution to play, record, convert and \
                stream audio and video.

long_description        FFmpeg is a complete solution to record, convert and \
                        stream audio and video. It includes libavcodec, the \
                        leading audio/video codec library. \
                        \
                        The project is made of several components: \
                        \
                        ffmpeg is a command line tool to convert one video \
                        file format to another. It also supports grabbing and \
                        encoding in real time from a TV card. \
                        \
                        ffserver is an HTTP (RTSP is being developped) \
                        multimedia streaming server for live broadcasts. Time \
                        shifting of live broadcast is also supported. \
                        \
                        ffplay is a simple media player based on SDL and on \
                        the ffmpeg libraries. \
                        \
                        ffprobe gathers information from multimedia streams and \
                        prints it in human- and machine-readable fashion. \
                        \
                        libavcodec is a library containing all the ffmpeg \
                        audio/video encoders and decoders. Most codecs were \
                        developped from scratch to ensure best performances \
                        and high code reusability. \
                        \
                        libavformat is a library containing parsers and \
                        generators for all common audio/video formats.
