You were right i was using the wrong binary, now the output is: ... - entity 5: OMAP3 ISP CCDC (3 pads, 9 links) type V4L2 subdev subtype Unknown flags 0 device node name /dev/v4l-subdev2 pad0: Sink [fmt:UYVY2X8/720x625 field:interlaced] ... pad1: Source [fmt:UYVY/720x624 field:interlaced crop.bounds:(0,0)/720x624 crop:(0,0)/720x624] ... - entity 16: tvp5150 1-005c (1 pad, 1 link) type V4L2 subdev subtype Unknown flags 0 device node name /dev/v4l-subdev8 pad0: Source [fmt:UYVY2X8/720x625 field:interlaced] but i still get the same error: root@igep00x0:~/field# ./yavta -f UYVY -n4 -s 720x624 -c100 /dev/video2 Device /dev/video2 opened. Device `OMAP3 ISP CCDC output' on `media' is a video output (without mplanes) device.

Unable to start streaming: Invalid argument (22). 4 buffers released. And ccdc pad1: Source (entity 5) is strange, i think it should be field:none (because ccdc output is deinterlaced).
