I will update the documentation in next version. Good catch. Removing the -u makes it work. clst@emb-xps-1:~$ yavta --data-prefix -c10 -n5 -I -s 1280x800 -- file=/tmp/frame-#.bin -f SBGGR10 /dev/video0 Device /dev/video0 opened.

I guess that after next merge window, the IPU6 patches can be rebased on top of Intel VSC sent upstream, and also changed to fit the changes in the V4L2 api. Regards Claus
