in libavcodec/Makefile there is in line 110: "distclean: clean<binary char>"
this binary char corrupts the makefile and should be removed.

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/ if you want to contribute or use the codec or format libraries. 3) Licensing: ------------ * See the file COPYING. ffmpeg and the associated library EXCEPT liba52 are licensed under the Lesser GNU General Public 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. Fabrice Bellard.
