Are your capture cards supported by v4l2 drivers ? If yes then only you can use v4l2src.<br><br>Assuming it supports, you need to figure out where is your card installed, like for my blackmagic capture card its /dev/blackmagic/card0 (although there is no v4l2 support, hence wrote our own src element for blackmagic).<br>
<br>So if its not supported by v4l2 you either check if any other src element supports your card or write one of your own :)<br><br>Best<br>Kapil<br><br><div class="gmail_quote">On Wed, Apr 14, 2010 at 4:22 AM, Kulecz, Walter (JSC-SK)[WYLE INTEG.

In the process of playing around with things, I've currently got three installed All work in a simple pipeline if I set the device property with C code using:<br>
<br>
g_object_set(G_OBJECT(source), "device", "/dev/video2", NULL)<br>
<br>
but the capture devices are different enough that I'm stumbling around with the caps, as only using unfiltered caps works for all three cards. The point of the exercise is to figure out if I can use our current assortment of PCI capture cards and add in some USB ones I've found.<br>
<br>
I'd prefer having to only deal with a single buffer type by forcing an input format common to all the capture devices if possible.<br>
<br>
So how can I get gst-inspect to list the properties of the other capture devices?<br>
