It appears to be finding the device but is running into some errors. My test pipeline: <tt>gst-launch-1.0.exe ksvideosrc device-index=0 ! autovideosink</tt> After executing that, I get an error that it cant create or open ksclock. It doesn't recognize the GUID for rgb8. And then it says it can't start capture because of reason 0x048f (ERROR_DEVICE_NOT_CONNECTED), even though the device is connected and I can capture it through VLC, directshow, and the Osprey capture card driver software. My best guess (looking over the source code near <a class="moz-txt-link-freetext" href="https://github.com/GStreamer/gst-plugins-bad/blob/master/sys/winks/gstksvideosrc.c#L961">https://github.com/GStreamer/gst-plugins-bad/blob/master/sys/winks/gstksvideosrc.c#L961</a> ), it appears to be getting the error from a call to GetOverlappedResult. I have tested with a USB webcam to verify that the ksvideosrc does at least work for something and it does work with a USB web camera. Also all devices on this card appear to have the same issue. I also get this same behavior from autovideosrc as well. Let me know if I can provide anymore information, or if anyone has any suggestions on things to try. Here is my GST_DEBUG=ks*:4 output: <tt>gst-launch-1.0.exe ksvideosrc device-index=0 ! autovideosink</tt><tt> </tt><tt>Setting pipeline to PAUSED ...</tt><tt> </tt><tt>0:00:00.273953842 1512
