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.
