Thanks a lot for all your replies. However, my question wasn't about CoreImage (I already knew the G4 Mini doesn't support it), nor about accelerated codecs, nor about the "user side", but about the "developer side" of the world.
I'd like to know the extensions, maximum values, etc, supported by OpenGL on the G4 Mini with 9200-64Mb at Tiger (10.4).
Apple keeps an "OpenGL capabilities" chart, and it had a column for 10.4, but they removed all old OS X versions from the chart, and I cannot find any backup on the web.
A GLinfo output would also help. Anybody has any of this for this machine?
