The Handbrake open-source video transcoder program now supports using OpenCL for accelerating certain operations along with introducing other new features to its brand new 0.9.9 release.
Handbrake 0.9.9 supports pushing video cropping and down-scaling operations to the graphics processor via OpenCL, thanks to work done by AMD. They also contributed a Windows-only DXVA video decode acceleration patch too. On the Intel side, there is now Quick Sync Video support for accelerating video operations. Quick Sync Video though is a Windows-only driver feature where on the Linux side their crew only exposes the video calls over VA-API.
Some other changes to find with Handbrake 0.9.9 include Blu-ray PGS sub-title support, support for new video frame-rates, better audio remixing support, updated libraries, and various other bug-fixes and improvements.
