I'm afraid it will have to be Windows, as I remember GEM performing 5-6 times worse on Mac than on Windows (reading and rendering video files i.e. using pix_film) and not only with h264.............
does it also happen when not reading and writing video ? I mean, make a patch that does a lot of pix processing on top of a [pix_image] and then just displays that with a single [pix_texture] or [pix_draw]. Is that kind of thing slower on OSX than on Windows and/or Linux ?
I ask because I wonder whether it can be linked with a problem I know about on OSX...
Sorry, I have no idea. All the patches I tried on Mac had only very basic or no pix processing but played back and displayed fragment of quite a few videos.
And right now (nor in the near future) I don't have access to a Mac to do more tests.
I thought the bottleneck was in reading and/or decoding the files rather than rendering, but now I can't remember what made me think that (if there was a good reason at all).
