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). |
