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][].

1.  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
2.  Then, I built OpenSSL as shown in [this post][this post 1].
    
        ./Configure -DHAVE_STRUCT_TIMESPEC -L/mingw/lib -lz -lpthreadGC2 -lws2_32 --prefix=/mingw threads zlib mingw
        make
        make install
3.  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
4.  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}
