Description Gwenole Beauchesne 2013-07-26 08:30:09 UTC

Hi, there are multiple combinations of video processing formats that are not supported, though advertised. In particular, YUY2-to-YUY2 is not supported. Here are some patches but this is not a good approach.

The better approach would be to move to dynamically generated kernels through librw for instance or iGPGPU. That way, more color formats could be supported with less effort, along with additional filters like ProcAmp enhancement.

Here are minimal patches, minimally tested on Ivybridge. I will let you generate the associated binary kernels since I also fixed the build for those, along the way.

Anyway, this is still not a good approach, please consider the other way instead. :)
