From 4745b5bf6cad82df283c032262316285a51660aa Mon Sep 17 00:00:00 2001 From: Fabrice Bellard Date: Tue, 19 Nov 2002 20:09:45 +0000 Subject: update Originally committed as revision 1236 to svn://svn.ffmpeg.org/ffmpeg/trunk --- README | 66 ++++++------------------------------------------------------------ 1 file changed, 6 insertions(+), 60 deletions(-) (limited to 'README') diff --git a/README b/README index 9144a32728..cadf5d55e9 100644 --- a/README +++ b/README @@ -1,70 +1,16 @@ -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 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. \ No newline at end of file -- cgit v1.2.3
