Juanjo 86bec9a161 - Fix on AVI and WAV headers based on Nikolai Zhubr patch.
- Now the properties of the AVIs are correctly shown, but the MP2 audio
isn't playable, it seems the problems is that Fraunhoffer MP3 decoder
included on Windows cannot decode MP2 streams.

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.
