Re: [GnomeMeeting-list] About recognition of a camera

[Katsumi Saito <katsumi jo1upk ymt prug or jp>]

I disturbed. Sorry.
I am sorry to be poor English.

I operated, although there was also a still a little strange place.

Now, it is GnomeMeeting.
The check of ja.po of operation can be performed now.

A message came to be displayed when re-compiling only GnomeMeeting.
-> Your driver doesn't support the YUV420P format.

o About Pop-up of a message.
  GnomeMeeting What RPM-ized and was introduced was strange.
  Spec file From GnomeMeeting 0.11 was taken out and used.
  It was not the problem of locale.

o About YUV420P.
  It will come to be recognized if the following programs are performed.

---
#include <stdio.h>
#include <sys/ioctl.h>
#include <fcntl.h>
#include <linux/videodev.h>

int dev;
int bytes_per_rgb;
struct video_picture vid_pic;

int main( int   argc, char *argv[] )
{
  int ib, ic, iw;

  dev = open ("/dev/video0", O_RDWR);
  if (dev < 0) {
          perror("/dev/video0");
          exit(1);
  }

  ioctl (dev, VIDIOCGPICT, &vid_pic); /* Get picture properties */

  ib = (vid_pic.brightness)/256;
  ic = (vid_pic.contrast)/256;
  iw = (vid_pic.colour)/256;

  vid_pic.palette = VIDEO_PALETTE_RGB24; /* 24bit RGB */
  bytes_per_rgb = 3;
  vid_pic.depth = 24;

  /* Set picture properties */
  if(ioctl (dev, VIDIOCSPICT, &vid_pic)) {
    perror("wrong palette/depth");
    exit( 1 );
  }

  return 0;
}

  Although /proc/cpia/video0 was referred to, 
  especially decisive contents were not detected.

  o proc.ng is error. / proc.ok is ok.
    Although checked several times, it is not, if it decides.
