remove opendivx #ifdefs remove rk1 filter remove unused / obsolete stuff add -1,4,2,4,-1 deinterlacing filter (ffmpeg uses that) threadsafe / no more non-const globals some optimizations different strides for Y,U,V possible remove ebx usage (someone really should fix gcc, this is really lame) change the dering filter slightly (tell me if its worse for any files) Originally committed as revision 7947 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc |

README
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 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.
