AMD, and NVIDIA before it, has been trying to convince us of the usefulness of its GPUs for general purpose applications for years now. For a while it seemed as if video transcoding would be the killer application for GPUs, that was until Intel’s Quick Sync showed up last year.

There’s a lot to talk about when it comes to accelerated video transcoding, really. Not the least of which is HandBrake’s dominance generally for anyone doing small scale size reductions of their DVD collections for transport on mobile devices. We owe it all to the open source x264 codec and all the programmers who have contributed to it over the years, standing on one another’s shoulders allowing us to effortlessly encode or transcode gigabytes of video to manageable sizes. But Intel has attempted to rock the boat by inserting itself into the fray by tooling its QuickSync technology for accelerating the compression and decompression of video frames. However it is a proprietary path pursued by a few small scale software vendors. And it prompts the question, when is open source going to benefit from the proprietary Intel QuickSync technology? Maybe its going to take a long time. Maybe it won’t happen at all. Lucky for the HandBrake users in the audience some attempt is being made now to re-engineer the x264 codec to take advantage of any OpenCL compliant hardware on a given computer.
