-1) Introduction
----------------
+FFmpeg README
+-------------
-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
+1) 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 the documentation in the doc/ directory.
-* Read doc/README.dev if you want to contribute or use the codec or
- format libraries.
-
-3) Licensing:
+2) Licensing
------------
-* See the file COPYING. ffmpeg and the associated library EXCEPT
+* Read the file COPYING. ffmpeg and the associated libraries EXCEPT

License. liba52 is distributed under the GNU General Public License.
-* 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 mostly the same.
