I believe some imx6 devices have a direct HDMI input interface. The 
nitrogen6x perhaps. Consult Boundary Devices.
The imx6 is pretty popular here, mainly because of the CODA patches that 
are going into the mainline Linux kernel. These use the imx6 VPU for 
hardware accelerated video decoding over V4L2. And GStreamer has since 
version 1.4 V4L elements for decoding.
