I'm a Free Software developer and multimedia professional running Debian GNU/Linux. I'm aware that VLC Player and Handbrake use OpenCL. Are there any other Free Software programs, preferably multimedia production software which utilize OpenCL? So far, I have found this developer mailing list discussion regarding the potential implementation of OpenCL/OpenGL on ffmpeg, which if accomplished, would be fantastic for what I do.
IIRC ImageMagick can also be compiled with OpenCL support, and I may be mistaken but some of the rework Gimp underwent to support OpenGL ES will also be/is also being used to add OpenCL support.
