Hi everybody,
I'd like to retrieve video frames from a video capture device
on embedded-linux.
I'm using a memory mapping from
the grabbing device initiliazed by a call to VIDIOCGMBUF.
In its own thread, I've a successfull call to
the VIDIOCMCAPTURE ioctl command. But when
I want to release my grabbed frame with the
VIDIOCSYNC command, it fails :-(
Do you have any idea on how to find the information
to solve this ? or how to configure device to acquire
video frames without a simple "read" call on the device ?
Thank's a lot.
Trick Lo.
