If you are installing Adobe CQ5, you’ll love the fact that FFmpeg integration is supported out of the box. The bad news is that due to licensing restrictions Adobe does not bundle FFmpeg with the standard CQ installation. Another issue is that the “standard” FFmpeg build does not include support for H264 which is useful for video playback on iOS devices etc.
Given that I had to repeat the installation process recently after reinstalling my MacBook AIR with Mountain Lion, I took some notes compiled from a few different sites into one quick cheat sheet. Note that this will take at least an hour to complete due to the need to download and compile a bunch of stuff.
