     46[https://ffmpeg.org/ffmpeg-filters.html#xfade_005fopencl xfade_opencl] is the Open CL variant of the xfade filter. This filter supports a subset of the filters available in xfade (see '''bold''' names in gallery above) and also supports creation of custom effects. It requires `ffmpeg` to be configured with `--enable-opencl` and you must initialize a hardware device in your command. See [https://ffmpeg.org/ffmpeg-filters.html#OpenCL-Video-Filters OpenCL Video Filters] for general info.
