But... Do the calls from video4linux make good use of this feature?
But i read Reinoud said a field capture time was the same than a frame. And i only want to use fields to can receive faster images.I've read in v4l2 manual v4l2_field is just i'm looking for...Exactly. Use V4L2_FIELD_ALTERNATE.
Thanks for your help.
