ksvideosrc: Failed to start capture

Michael MacIntosh

Hi,

I am on windows 10 using gstreamer 1.12 and I am trying to capture video from an Osprey 460e analog capture card, and I was running into any difficulties using the ksvideosrc element.

It appears to be finding the device but is running into some errors.

My test pipeline:

gst-launch-1.0.exe ksvideosrc device-index=0 ! autovideosink

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 https://github.com/GStreamer/gst-plugins-bad/blob/master/sys/winks/gstksvideosrc.c#L961 ), 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:


gst-launch-1.0.exe ksvideosrc device-index=0 ! autovideosink

I think you should file a bug report about this. See bugs.gnome.org,
product GStreamer componenent gst-plugins-bad.

Re: ksvideosrc: Failed to start capture

Michael MacIntosh

Apparently the issue is the capture card I am recording from requires a crossbar, which apparently isn't getting added to the graph.

I found someone had a similar issue with dshowvideosrc with gstreamer version 0.10.4

http://gstreamer-devel.966125.n4.nabble.com/Grabbing-analog-video-source-with-gstreamer-tp973110.html

I also observe the same, "not connected", behavior in graphedit if I try to render the preview or capture pins of the source without the crossbar attached to the video source (crossbar -> videosrc -> video renderer).

I am just wondering if this issue has a workaround.

Cheers,

Michael.
