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.

mplanes) device.

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