We have an application where we mix video playback with captured sources from HDMI inputs and show the composition in real-time. A simple example of this could be video file as background and presentation from laptop embedded as PIP. In some cases, these presentations can be HDCP protected. It would be hugely beneficial if NVIDIA drivers would support HDCP. This is the only thing we are lacking since the support is there already by the capture card manufacturers.
With the new kernel, the pipeline would work with Intel GPUs now that they do support HDCP, but these GPUs are not an option for us. Have you reconsidered the Linux support now that Intel has moved forward in this?
