I would like to use imx6q IPU open overlay function, and V4L2 capture in the same time.
but overlay normal display, v4l2 capture fuction :ioctl(fd_v4l, VIDIOC_DQBUF, &queue_buf))error:
v4l2 capture: mxc_v4l_dqueue ERROR: timeout enc_counter 0.
How to solve it?
In addition, can use the mxc_v4l2_test example to solve v4l2 get frame buffer and ipu overlay display?
