Missing Argus support for low frame resolution cameras

Yes, VC1 is on /dev/video0 and VC0 is on /dev/video1:

# v4l2-ctl -d /dev/video0 -V
Format Video Capture:
	Width/Height      : 1280/800
	Pixel Format      : 'BG10' (10-bit Bayer BGBG/GRGR)
	Field             : None
	Bytes per Line    : 2560
	Size Image        : 2048000
	Colorspace        : sRGB
	Transfer Function : Default (maps to sRGB)
	YCbCr/HSV Encoding: Default (maps to ITU-R 601)
	Quantization      : Default (maps to Full Range)
	Flags             : 

# v4l2-ctl -d /dev/video1 -V
Format Video Capture:
        Width/Height      : 224/173
        Pixel Format      : 'BG12' (12-bit Bayer BGBG/GRGR)
        Field             : None
        Bytes per Line    : 512
        Size Image        : 88576
        Colorspace        : sRGB
        Transfer Function : Default (maps to sRGB)
        YCbCr/HSV Encoding: Default (maps to ITU-R 601)
        Quantization      : Default (maps to Full Range)
        Flags             :

Streaming both virtual channels at the same time works:

# v4l2-ctl -d /dev/video0  -c bypass_mode=0 --stream-mmap --stream-count=1000
<<<<<<<<<<<<<<<<<<<<<< 20.12 fps
<<<<<<<<<<<<<<<<<<<< 20.12 fps
<<<<<<<<<<<<<<<<<<<< 20.12 fps
<<<<<<<<<<<<<<<<<<<< 20.12 fps
...

# v4l2-ctl -d /dev/video1  -c bypass_mode=0 --stream-mmap --stream-count=1000
<<<<<<<<<<<<<<<<<<<<<< 20.01 fps
<<<<<<<<<<<<<<<<<<<< 20.01 fps
<<<<<<<<<<<<<<<<<<<< 20.01 fps
<<<<<<<<<<<<<<<<<<<< 20.01 fps
<<<<<<<<<<<<<<<<<<<< 20.01 fps
...

But we want to stream VC1 (1280x800 camera) via ISP to do debayering, etc.
