Cross-compiling ffmpeg for windows

I recently had to cross-compile ffmpeg for windows, which is a fairly length process, detailed at this site.

However, upon trying to download the key from the keyserver, it seems that keyserver.net is down. A check of the forum showed that others were having the same problem:

gpg --keyserver www.keyserver.net --recv-key 0x25E635F9

gpg: cannot connect to keyserver

To make matters worse, a bug in Ubuntu means that apt cannot be told to allow unauthenticated connections, so you're stuffed.

If you're coming across this issue, the author has now uploaded the key to a few other servers, so you can get the key with this command:

gpg --keyserver keyserver.ubuntu.com --recv-key 0x25E635F9
