I am trying to build the Mac version myself (my wife has kindly let me use her new MacBook Pro, in return for more diligent household services). But it looks like it will not be easy. Not for the reason I was expecting -- problems building/linking the ffmpeg libraries -- no trouble with that.
The problem is that I have written all the OpenGL code to version 3.2 standard, relying on Apple's claim that OSX 10.7+ supports that. But now that I have built Panini-Video on 10.7.5 I find that Qt can only deliver the old OGL 2.1 driver context (and I would not be surprised if it was a s/w implementation)! There is no doubt some way around this, however I have found no public information as to how to do it, and expect it will not be quick.
The more I try to use OpenGL on Mac, the more I hate Apple. They are worse than Microsoft at making you jump through proprietary hoops to access 'open' facilities, and evidently don't really think OpenGL should be 'open' -- or even implemented correctly (see my old flames about large cubic textures crashing OS X before 10.5).
On the plus side, the current Qt SDK knows how to build mac bundles without resort to xcode.
So just wish me luck.
