<div>
<div>Thanks for you answer!</div>
<div>Wenn I check if the kernel detects my camera with dmesg -wH, I see it detects the camera within a second, or less.</div>
<div>But using gstreamer in monitor mode,</div>
<div>$ gst-device-monitor-1.0 -f</div>
<div>gstreamer does not detect my camera. There is no delay detecting, it does not detect it.</div>
<div> </div>
<div>I am running openSUSE 13.2. It is a problem from the OS?</div>
<div> </div>

<div>Re-hi again,

<div>I can also see the long detection delay with gst-device-monitor-1.0 command.</div>

<div>Re-hi,
<div>I want to be more precise.</div>
<div>It can take upto 10 - 15 seconds before audio-recorder (or gstreamer monitor) detects new hw.</div>
<div>The device (like my USB webcam with mic) appears in the GUI but the delay feels like a bug.</div>

<div>It is a logitech camera, an USB Webcam.</div>
<div>I am running Suse Linux.</div>
<div>When I connect the camera it appears in /dev the new device, /dev/video0.</div>
<div>And I added :</div>
<div> if (!gst_device_monitor_start (monitor))<br/>
g_error ("Failed to start device monitor!");</div>
<div> </div>
<div>to check if device monitor starts, and it starts without an error.</div>

<div><span>Hi,<br/>
<br/>
Is it a USB Webcam? Are you running a generic desktop distribution<br/>
(Fedora, Ubuntu, etc) or something strange?<br/>
When you connect the camera, does a /dev/video<X> device appear? Check<br/>
the return value of gst_device_monitor_start().</span></div>
<div><br/>
