ksvideosrc with video capture card

[Lóránt Labádi]

Hi guys,

I'm trying to capture video from a frame grabber card but I got an issue:

gst_device_monitor's output:

Device found:

         name  : D4-PREV8 PCIe Video Capture
         class : Video/Source

I tried:

gst-launch-1.0 ksvideosrc 
device-path="\\\\\?\\pci\#ven_1c04\&dev_0010\&subsys_00111c04\&rev_01\#8\&2d8ac41c\&0\&002800480008\#\{6994ad05-93ef-11d0-a3cc-00a0c9223196\}\\\{46d01bbe-d9d5-4027-a95f-c01ae2ade565\}" 
! autovideosink
