It can grab from a standard Video4Linux video source and -convert it into several file formats based on DCT/motion compensation -encoding. Sound is compressed in MPEG audio layer 2 or using an AC3 -compatible stream. - -What makes ffmpeg interesting ? - -- Innovative streaming technology : multiformat, real time encoding, - simple configuration. - -- Simple and efficient video encoder: outputs MPEG1, H263 and Real - Video(tm) compatible bitstreams using the same encoder core. - -- Real time encoding (25 fps in 352x288 on a K6 500) using the video4linux API. - -- Generates I and P frames, which means it is far better than a MJPEG - encoder. - -- Hyper fast MPEG audio layer 2 compression (50 times faster than - realtime on a K6 500). - -- Hyper fast AC3 compatible encoder. - -- simple and very small portable C source code, easy to understand and - to modify. It be may the smallest decent MPEG encoder :-) - -ffmpeg is made of two programs: - -* ffmpeg: soft VCR which encodes in real time to several formats. - -* ffserver: live broadcast streaming server based on the ffmpeg core -encoders. - -2) Documentation +1) Documentation ---------------- -read doc/ffmpeg.txt and doc/ffserver.txt to learn the basic features. - -read ffmpeg +* Read the documentation in the doc/ directory. -3) Licensing: +2) Licensing ------------ -* See the file COPYING. ffmpeg is licensed under the GNU General +* Read the file COPYING. ffmpeg and the associated libraries EXCEPT + liba52 and libpostproc are licensed under the Lesser GNU General Public License. -* Source code from third parties: The DCT code comes from the Berkeley - MPEG decoder and the JPEG encoder. - -* This code should be patent free since it is very simple. I took care - to use the same video encoder core for all formats to show that they - really ARE THE SAME except for the encoding huffman codes. +* liba52 and libpostproc are distributed under the GNU General Public + License and their compilation and use is optional in ffmpeg. -Gerard Lantau (glantau@users.sourceforge.net). +Fabrice Bellard. \ No newline at end of file
