Hardware encoding support with MCEBuddy running as a Service and Command Line just went live. Right now it supports OpenCL 1.2 (QuickSync and NVidia OpenCL for newer cards which support OpenCL 1.2). Currently only handbrake provides support for OpenCL encoding but MCEBuddy has been designed to support Mencoder and ffmpeg encoders also if future versions support hardware encoding.
For those who like to experiment, you can build and use the OpenCL version of ffmpeg (which support unshake and unsharp filters via OpenCL) and the current build of ffmpeg that comes with MCEBuddy allows x264lib to use OpenCL for lookahead offloading. To enable this you will need to manually edit the ffmpeg-video section and under x264opts add "opencl" to it. Google it for details. Note however that x264 in ffmpeg and opencl are still not very stable.
I haven't seen any build of mencoder which support OpenCL or any hardware encoding, however if it comes along, pop it in , customize the profile and you're ready to go.
