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.

And ccdc pad1: Source (entity 5) is strange, i think it should be
field:none (because ccdc output is deinterlaced).
