FFmpeg - (c) 2000,2001 Gerard Lantau.

1) Introduction
---------------

ffmpeg is a hyper fast realtime audio/video encoder, a streaming
server and a generic audio and video file converter.

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, 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
----------------

* 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.

3) 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!).

* 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.
