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 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 \
                    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 \
                    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.
