Hello,
My video capture application runs perfectly after the DaVinci box is up.
The application grabs a video and displays it on TV. The application uses
V4L2 driver for this.
I want to do the same job, at the time of booting the box. The intention
is to get the display at TV before the linux prompt comes. I have checked
that "DaVinci v4l2 capture driver V1.0 loaded" message comes much earlier
(from function vpfe_init) , and at that point I want to open a kernel
thread to do capture and display function.
My question is
1. If the function vpfe_init is the correct point to do capture-display
kernel thread?
2. My original application(which runs after the box boots up) does
"open("/dev/video0", O_RDWR | O_NONBLOCK, 0); open("/dev/fb/3", O_RDWR);
ioctl(fd, VIDIOC_QUERYCAP, &cap)" etc calls. What are the equivalent calls
if I want to open the devices and do ioctl from the vpfe_init function?
