Hi Igor,
I reckon this "someone" could be me?
I have build cubox kernel with the below diff on the "linux-imx6-current.config" and it apparently works.
+CONFIG_MEDIA_PLATFORM_SUPPORT=y
+CONFIG_V4L2_JPEG_HELPER=m
+CONFIG_V4L_MEM2MEM_DRIVERS=y
+CONFIG_VIDEO_CODA=m
+CONFIG_VIDEO_IMX_VDOA=m
1. Kernel boots and is detecting the codec
[ 29.911784] coda 2040000.vpu: Direct firmware load for vpu_fw_imx6d.bin failed with error -2

2. v4l2-ctl reports the devices as being CODA960
CODA960 (platform:coda):
/dev/video0
/dev/video1
/dev/video2
/dev/video3
imx-capture (platform:ipu1_csi0):
/dev/video4
imx-capture (platform:ipu1_csi1):
/dev/video7
imx-capture (platform:ipu1_ic_prpenc):
/dev/video5
imx-capture (platform:ipu1_ic_prpvf):
/dev/video6
3. GStreamer has plugins for V4L2 video decoder, so finally lets give it a try with some h.264...
gst-launch-1.0 filesrc location=Big_Buck_Bunny_720_10s_30MB.mp4 ! qtdemux name=demux demux.video_0 ! queue ! h264parse ! v4l2h264dec ! kmssink
The video is ok, cat /proc/interrupts shows activity on the VPU, and the CPU load is low (5%-10% on i.mx.6 SOLO!), so the video acceleration is there!.
Igor, can you take it from here and integrate it or should I dare and make a PR for this?
