You are free to correct it.

Can you include a Windows DLL loader to support it ? + +No. FFmpeg only supports open source codecs. Windows DLLs are not +portable, bloated and often slow. + +@chapter Development + +@section Can you support my C compiler XXX ? + +No. Only GCC is supported. GCC is ported on most systems available and I +don't see the need to pollute the source code with @code{#ifdef}s +related to the compiler. + +@section I want to use ffmpeg or libavcodec under Windows. Can you support my proprietary C compiler XXX ? + +No. Use @code{mingw-gcc} available at @url{http://www.mingw.org/} to +compile the code. It generates object files fully compatible with other +windows compilers. + +@section Can you add automake, libtool or autoconf support ? + +No. These tools are too blowted and they complicate the build. Moreover, +since only @samp{gcc} is supported they would add little advantages in +terms of portability. + +@bye |
