VIDIOCSYNC ioctl will not return - DC10

[Marcio Calixto Cabral <mcabral@xxxxxxxxxx>]

 Hi,

 When I issue ioctl(VIDIOCSYNC) the ioctl never returns. Xawtv runs fine
and I can see the input from my camera.

 Here is the code:

  if (ioctl (fdVideoDev, VIDIOCMCAPTURE, &vd.buf_v4l) == -1) {
    perror ("VIDIOCMCAPTURE");
    munmap (map, vd.CapturedFrameBuffer.size);
    return (NULL);
  }
  int Frame = 0;
  if (ioctl (fdVideoDev, VIDIOCSYNC, &Frame) == -1) {
    perror ("VIDIOCSYNC");
    munmap (map, vd.CapturedFrameBuffer.size);
    return (NULL);
  }

 Is there anythinh else I should add?

 Thanks in advance for any reply.
