Hi all,
The permission issue seems to be related to the security framework in
Linux (probably ConsoleKit?). This is something that's causing a lot
of trouble among Fedora 8 users right now. But my guess is that it's
gonna happen for other Linux distros too. I fixed it (I don't know if
it's the ultimate solution) by adding these lines in
/etc/security/console.perms.d/50-default.perm :
<sound>=/dev/snd/*
<video>=/dev/video*
<console> 0600 <sound> 0600 root
<console> 0600 <video> 0600 root
Now, as far as LiveCam is concerned, the inability to read frames is
due to a small modification (an extra check) I introduced in the
kernel drivers for m5603c-mt9v011 and m5602-ov9650 where LiveCam
should mark a buffer as intended for capture before submitting the
ioctl to dequeue one. So all you have to do is add this line in
v4l2widget.cpp, in the function WorkerThread just before the ioctl:
buffer.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
so that the prologue of WorkerThread becomes:
138 void* WorkerThread(void* pData)
139 {
140 V4L2Widget* pV4L2Widget = (V4L2Widget*)pData;
141 struct v4l2_buffer buffer;
142 struct timespec req, rem;
143
144 while (pV4L2Widget->m_Capture == true)
145 {
146 buffer.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
147 ioctl(pV4L2Widget->m_fd, VIDIOC_DQBUF, &buffer); // Should block.
I'm going to update the SVN repositories this week-end.
BR,
Ilyes Gouta.
