setting the pipeline (CSI) as SRGGB10 (16 bit samples) as per below
media-ctl --reset
media-ctl -v -V '"imx577 '19-001a'":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -V '"msm_csiphy3":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]'
media-ctl -l '"msm_csiphy3":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
allows to capture SRGGB10P samples (frames-xxxx.bin files contain 10 bit samples for the size)
==> yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video0
shouldnt the CSI need to be set to SRGGB10P instead?
