本文详细介绍了如何为ffmpeg和mplayer等开源项目构建libRTMP库的过程。包括编译zlib、OpenSSL以及最终构建libRTMP的具体步骤，并提供了安装共享库及头文件的方法。

The libRTMP library provides online multimedia streaming support for many open-source projects, such as ffmpeg and curl. I am building librtmp for use with ffmpeg and mplayer. I downloaded the latest release tarball from here.

First, I compiled zlib as shown in this post.

make -f win32/Makefile.gcc
cp -iv zlib1.dll /mingw/bin
cp -iv zconf.h zlib.h /mingw/include
cp -iv libz.a /mingw/lib
cp -iv libz.dll.a /mingw/lib

Then, I built OpenSSL as shown in this post.

./Configure -DHAVE_STRUCT_TIMESPEC -L/mingw/lib -lz -lpthreadGC2 -lws2_32 --prefix=/mingw threads zlib mingw
make
make install

Then, I built librtmp.

make SYS=mingw
cp -iv *.exe /mingw/bin

To build the shared library, I typed:

cd librtmp
gcc -shared -o librtmp.dll -Wl,--out-implib,librtmp.dll.a rtmp.o log.o amf.o hashswf.o parseurl.o -lssl -lcrypto -lz -lws2_32 -lwinmm -lgdi32

To install librtmp, I typed the following:

cp -iv librtmp.dll /mingw/bin
cp -iv amf.h http.h log.h rtmp.h /mingw/include/librtmp
cp -iv librtmp*.a /mingw/lib
cp -iv librtmp.pc /mingw/lib/pkgconfig

Sometimes, librtmp.pc fails to be generated. In that case, make it yourself and copy it to /mingw/lib/pkgconfig.

prefix=/mingw
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
incdir=${prefix}/include/librtmp

Name: librtmp
Description: RTMP implementation
Version: 2.3
Requires: openssl libcrypto
URL: http://rtmpdump.mplayerhq.hu
Libs: -L${libdir} -lrtmp -lz
Libs.private: -lws2_32 -lwinmm -lgdi32 -lssl -lcrypto
Cflags: -I${incdir}
