I just got word from a commenter that RTMPDump 2.4 is out (thanks!). Since the release of Xcode 4 I have been unable to compile the RTMPDump binaries using the supplied Makefile. Actually, the binaries are all there but I always get a signal fault when the rtmpdump binary tries to establish a connection to a target server. I had to resort to plan B which was to import the RTMPDump sources into Xcode and to create a proper console application project. Read more »

Since a few days you may get a warning using RTMPDump v2.3 saying “WARNING: HandShake: Server not genuine Adobe!”. RTMPDump v2.3 usually quits with a handshake error after it’s instructed to use a type 9 handshake by the server. For some sites using the older RTMPDump version 2.1d fixes the problem. If you’re on Mac OS X 10.6 or higher you can download the older binary from this site’s download area.

RTMPDump is a very powerful software to download/capture Flash streams. It’s incredibly useful for sites that don’t let you download Flash videos for offline usage. And you know what, it’s free to use (GPLv2)! RTMPDump is command line only though so if you’re looking for a nice user interface, RTMPDump may not be for you.
If you want to use the latest version of RTMPDump you need to compile it on the Mac as there’s no official version provided for Mac OS X. Compiling RTMPDump is pretty easy even though you need to modify a Makefile in order to build the binary. You also need a build environment like Apple Xcode. If you decide to download my binary of RTMPDump you can skip the next section about compiling it. The RTMPDump binary runs pretty well on Snow Leopard 10.6.4 but may not do so on earlier version of Mac OS X. Read more »
