1) API ------ * libavcodec is the library containing the codecs (both encoding and decoding). See libavcodec/apiexample.c to see how to use it. * libav is the library containing the file formats handling (mux and demux code for several formats). (no example yet, the API is likely to evolve). 2) Integrating libavXXX in your GPL'ed program ---------------------------------------------- You can integrate all the source code of the libraries to link them statically to avoid any version problem. All you need is to provide a 'config.mak' and a 'config.h' in the parent directory. See the defines generated by ./configure to understand what is needed. 3) Coding Rules --------------- ffmpeg is programmed in ANSI C language. GCC extension are tolerated. TAB size is 4. The identation is the one specified by 'indent -i4 -kr'. Main priority in ffmpeg is simplicity and small code size (=less bugs).
