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.
