- IsCrtShaderEnabled now guards on SupportsHwaccel("opencl"),
SupportsFilter("program_opencl") and SupportsFilter("scale_opencl")
so the filter is silently skipped instead of causing an FFmpeg error
when OpenCL is unavailable
- Drop w=iw:h=ih from scale_opencl (iw/ih are not valid expressions in
the OpenCL scale filter; omitting them defaults to input dimensions)
