Hi Steve,

If I make this change I get:

# v4l2-ctl --stream-mmap -d /dev/video1
[  501.143012] ipu1_ic_prpenc: capture format not valid
                VIDIOC_STREAMON returned -1 (Invalid argument)

Going back to the original example:

#  media-ctl -V "'ipu1_ic_prpenc':1 [fmt:AYUV32/640x480]"
# v4l2-ctl --stream-mmap -d /dev/video1
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 30.03 fps

Changing only the resolution:

#  media-ctl -V "'ipu1_ic_prpenc':1 [fmt:AYUV32/800x600]"
# v4l2-ctl --stream-mmap -d /dev/video1
[  658.358246] ipu1_ic_prpenc: capture format not valid
                VIDIOC_STREAMON returned -1 (Invalid argument)

Any ideas?

These are the lines I am currently using as per your feedback:

   media-ctl -l "'imx6-mipi-csi2':1 -> 'ipu1_csi0_mux':0[1]"

   media-ctl -V "'ipu1_ic_prpenc':1 [fmt:ARGB8888_1X32/800x600]"

Thanks,
