Failed to find any device to open DMK23G445

[leonhartyao]

Describe the bug I was trying to verify the installation for two DMK23G445 cameras. They are responsive to tcam-gigetool. However, there is no device listed in tcam-capture.

• Running gst-launch-1.0 tcambin ! videoconvert ! ximagesink returns the following error:

gst-launch-1.0 --gst-debug=tcamsrc:5 tcambin ! videoconvert ! ximagesink

Just saw that the current version doesn't support the cam model. I have to use older version.

The current version can support your camera too:

export TCAM_DISABLE_DEVICE_BLACKLIST=1
