Recently, the videodev2.h thread reminded me an old problem with the video4linux (or is it v4l?) backend. That is, only the first "scan" produces a (more or less) correct image, while the others have the succesive scanlines badly shifted. Is it normal? Can it be avoided? I know I can use other software (like XawTV) to take snapshots, but if there is such a SANE backend, it should work correctly. Also, a v4l2 backend would be welcome too.
