The readme of rtmpdump says:
Code:
To compile just type
$ make rtmpdump
$ make streams
or to cross compile
$ make -f MakefileWIN32 rtmpdump
$ make -f MakefileARM rtmpdump
$ make -f MakefileARM streams
So it seems to be pretty easy to compile rtmpdump in Linux. You just need the boost libraries and libssl-dev package.
I believe that in Windows you need cygwin, plus the boost libraries, libssl and gcc/c++ compiler should be available under cygwin.
I saw a blog post about compiling rtmpdump 1.3d with Visual Studio 2008 without cygwin, but it is about an old version an the author wasn't sure he did everything properly.
Please let me know how it goes...
