Comment (by jkqxz):

 Compiling ffmpeg with OpenCL requires headers and a linkable library of
 version at least 1.2.  The library can be either a vendor ICD, which will
 give you specific support for some set of platforms from that vendor, or
 the standard ICD loader, in which case it should be portable.  It is
 recommended but not required that you link to the ICD loader.
