I have installed the latest zoran drivers, and
I can successfully open a video device, but when
I try to change the window size:
status = ioctl(fd,VIDIOCSWIN,&vid_win);
I always get a message in /var/log/messages:
DC10plus[0]: VIDIOCSWIN: frame buffer has to be set first
I have tried to use:
ret_code = ioctl(fd, VIDIOCSFBUF, &vid_buf);
where vid_buf.base = NULL, but this doesn't help, since
as soon as I call the size change, it still complains.
I have looked at the zoran.c and it appears that if
the base address of the video_buffer is NULL, then the
above error message is always displayed.
Is there a way I can get the address for my card?
The chipset is the ZR36060.
All help appreciated,
Tom
