description         FFmpeg is a complete solution to play, record, \
                    convert and stream audio and video.
long_description    {*}${description}. 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 developed) \
                    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 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 \
                    developed from scratch to ensure best performance \
                    and high code reusability. \
                    \
                    libavformat is a library containing parsers and \
                    generators for all common audio/video formats.
