imx6q VPU support

[flobro]

we are "stuck" with Linux 4.9.175 kernel with iMX6q and are looking for a solution for VPU video decoding. I see that there is a VPU driver in the kernel,  but I assume that more support is needed for doing a simple decode.

Questions: Do I need CONFIG_MXC_GPU_VIV with CONFIG_MXC_VPU? 

I cannot seem to get the CONFIG_MXC_GPU_VIV to stick in menuconfig (I save it, then go back in and it is disabled...)

Thanks in advance.

Thank you for the reply. I will try that.

The current code I have seems to lock up the kernel as soon as the module loads.

If you are using mainline kernel version, you may need porting VPU driver from kernel we release.

I managed to get the imxvpudec driver(s) working with gstreamer to decode video files to jpeg/png frames. The only issue is there seems to be no support for "videorate' (maybe due to no timestamps in the video) - so the issue is speed.

Anyone know of a simple VPU decoder test? (does it use vpuwrap, or some other library)...
