Hi Lionnel -
I tested your monitor on a 4-port Quatro Falcon board (4 physical bt878
chips). It worked, but I had to do a few changes in video.c to make it work
(also, i'm using ntsc).
1st, I had to clear the vid_chnl structure and do a VIDIOCGCHAN to get
current parameters. 2nd, I set the vid_chnl.norm to NTSC, and the
vid_chnl.channel to mux input port 0. Up until then, the VIDIOCSCHAN would
fail.
Thats it for now. Nice work.
Joe
// start jvb
memset(&vid_chnl,0,sizeof(vid_chnl));
if( (ioctl(s->dev,VIDIOCGCHAN,&vid_chnl)) < 0 )
{
fprintf(stderr,"ERROR:ioctl: VIDEOCGCHAN[%s]
%s\n",device,strerror(errno));
return NULL;
}
vid_chnl.channel = VIDEO_MODE_NTSC;
vid_chnl.norm = VIDEO_PALETTE_YUV420P; // RGB24
vid_chnl.norm = 1; // pal
vid_chnl.channel = 0; //
// end jvb
if (ioctl (s->dev, VIDIOCSCHAN, &vid_chnl) == -1) // select
channel
{
perror("ioctl (VIDIOCSCHAN) failed");
return NULL;
}
