FFmpeg version 0.9 - (c) 2000 Gerard Lantau. 1) Introduction --------------- ffmpeg is a hyper fast realtime audio/video encoder and streaming server. 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 ---------------- read doc/ffmpeg.txt and doc/ffserver.txt to learn the basic features. read ffmpeg 3) Licensing: ------------ * See the file COPYING. ffmpeg is licensed under the 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. Gerard Lantau (glantau@users.sourceforge.net).
