6.5.2 Video4Linux API test
There are test applications named mxc_v4l2_test.c and mxc_v4l2_output.c under the
<ltib_dir>/rpm/BUILD/imx-test-"version"/test/mxc_v4l2_test directory.
Before running the v4l2 capture test application, make sure that the /dev/v4l/video0 is
created.
Test ID: FSL-UT-V4L2-capture-0010
# mxc_v4l2_capture.out -iw 640 -ih 480 -m 0 -r 0 -c 50 -fr 30 test.yuv
Capture the camera and store the 50 frames of YUV420 (VGA size)to a file called
test.yuv and set the frame rate to 30 fps. Look at mxc_v4l2_capture.out -help to see
usage.
Test ID: FSL-UT-V4L2-overlay-sdc-0010
# mxc_v4l2_overlay.out -iw 640 -ih 480 -it 0 -il 0 -ow 160 -oh 160 -ot 20 -ol 20 -r

of
interest is 640 X 480 with starting offset(0,0), the preview size is 160 X 160 with
