I try to obtain the image by the image interface on DM36X EVM.
First of all, sample program (examples-davinci.tar.gz) was obtained on the following page.
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_3_10/latest/index_FDS.html
examples-davinci.tar.gz was defrosted, and make did "examples-r37/imp-prev-rsz/dm365/capture_prev_rsz_onthe_fly_bayer.c".
It becomes an error because of the following calls if it executes it.
ioctl (fdCapture, VIDIOC_S_INPUT, &input.index)
The following messages are displayed in the console.

Are some settings necessary?
