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, Real - Video(tm), MPEG4, DIVX and MJPEG 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 :-) - -- optional non real time higher quality encoding (different motion - estimators available). - -- Audio and Video decoders are in development. - -ffmpeg is made of two programs: - -* ffmpeg: soft VCR which encodes in real time to several formats. It - can also encode from any supported input file format to any input - supported format. - -* ffserver: high performance 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 doc/TODO to know what are the know bugs and missing features. - -* Read doc/README.dev if you want to contribute or use the codec or - format libraries. +* Read the documentation in the doc/ directory. -3) Licensing: +2) Licensing ------------ -* See the file COPYING. ffmpeg and the associated library are licensed - under the GNU General Public License. I may change the license of - libavcodec and libav to LGPL if many people ask it (and if they - submit good patches!). +* Read the file COPYING. ffmpeg and the associated libraries EXCEPT + liba52 and libpostproc are licensed under the Lesser GNU General + Public License. -* This code should be patent free since it is very simple. I took care - to use the same video encoder/decoder 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@yahoo.fr). +Fabrice Bellard. \ No newline at end of file
