An anonymous reader writes "The recent critical zero-day security flaw in Flash 10 may have fast-tracked the release of Flash 10.1 today. Adobe 10.1 boasts the much anticipated H.264 hardware acceleration. Except for Linux and Mac OS (PDF): 'Flash Player 10.1, H.264 hardware acceleration is not supported under Linux and Mac OS. 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.' Your humble anonymous reporter, who is using Fedora Linux with a ATI IGP 340M, is very pleased that the developers of the OSS drivers have provided hardware acceleration for my GPU ('glxinfo : direct rendering: Yes,' 'OpenGL renderer string: Mesa DRI R100 (RS200 4337) 20090101 NO-TCL DRI2'), but even if Adobe did provide hardware acceleration for H.264 on Linux, they wouldn't provide it for me because they disable it for GPUs with SGI in the Client vendor string. Adobe 10.1, with all its goodness, now gives me around 95% CPU usage as opposed to about 75% with the previous release. Good times. I anticipate my Windows friends will have a much better experience."
