[Linphone-developers] no image while local video capturing.

[maillist66]

I cross compiled linphone-1.6.0 to i.MX31 successfully,Now I can run linphone well in graphic mode.

 

But I can not receive local image.The vedio window is black.

I got the following messages with command line : linphonec -V -d 6

 

INFO: no logfile, logging to stdout

so I tried to fix this, I uncomment these lines in file mediastream2/src/msv4l.c

/*      for (i = 0; i < s->frame_max; ++i) {
                struct v4l2_buffer buf;

                memset(&buf,0,sizeof(buf));
                buf.type        = V4L2_BUF_TYPE_VIDEO_CAPTURE;
                buf.memory      = V4L2_MEMORY_MMAP;
                buf.index       = i;
                if (-1==ioctl (s->fd, VIDIOC_QBUF, &buf)){
                        ms_error("VIDIOC_QBUF failed: %s",strerror(errno));
                }
        }
*/ 

 

But there is no local image neither in the video window but filled with color green.

 

this time I got these messages:
