[gst-devel] Re : Re : Grabbing analog video source with gstreamer

[Julien Isorce]

(reply to the gst list)

Note that you should have the same error doing:

set GST_DEBUG=1
gst-launch dshowvideosrc ! fakesink

About the reason of the error, you should have this error only if you
disconnect the usb link.

-->Anything with right bouton on the capture filter in graphedit, to open
the property page ?
-->property page on the ouput pin ?
-->Is there a software joined to the device ? does it work ?
