Sorry, I haven't heard of any progress on this yet... here's the best current guidance I've seen:<p>&#60;em&#62;"In Flash Player 10.1, H.264 hardware acceleration is not supported under either Linux or Mac OS X. Linux currently lacks a developed standard API that supports H.264 hardware video decoding, and Mac OS X does not expose access to the required APIs. The Flash Player team will continue to evaluate adding hardware acceleration to Linux and Mac OS X in future releases."&#60;/em&#62;
