It was in early April that AMD provided open-source Radeon UVD video acceleration code at long last for the past few generations of Radeon HD graphics cards for use by their open-source Linux driver. This allows applications that support VDPAU (the Video Decode and Presentation API for Unix) to leverage GPU-based video hardware acceleration.
While the code is beginning to be merged, after last month's code drop, I documented the steps to get Radeon UVD working on Ubuntu Linux. Now a Phoronix reader has documented how to get Radeon UVD up and running on Fedora.
The steps for getting open-source UVD working on Fedora 18 are close to what's needed on Ubuntu Linux with some obvious minor changes. There's also some experimental RPM packages with the necessary components to ease the setup process.
