description	Digital VCR and streaming server
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. \
			\
			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.
