Well, ok, so I’ve not actually done it, but it should at least now be possible using oaCapture.
Using a bundle of bits from the macports repository I now have oaCapture building on 64-bit OSX and it appears to work nicely as the image below shows. The build wasn’t even that problematic and there aren’t really any significant differences between the Linux and OSX. Certainly it’s easy to build on both environments from a single source set.
The major difference is which cameras are supported. On Linux, the TIS cameras and SPC900 are effectively supported for free because the drivers are in the kernel. On OSX the only cameras supported are those for which the vendor supplies an SDK, or those for which I’ve written my own drivers. The game is far from over however and I expect the range of supported cameras to increase dramatically over time.
