Hi Bryan!

These commands are to set up the pipeline, and what then to grab an
image from it?

I tried this, but it also just hangs:

$ yavta -B capture-mplane --capture=3 -n 3 -f SRGGB10P -s 4056x3040 /dev/video0 --file=foo-#.bin
Device /dev/video0 opened.
Device `Qualcomm Camera Subsystem' on `platform:acb3000.camss' (driver 'qcom-camss') supports video, capture, with mplanes.
