I figured out how to modify a .cfg file for arv-test and how to enable the schema check.
I can see the genicam:schema SUCCESS on a Point Grey GigEV camera.
I only get genicam:schema FAILURE when using our camera. Even with the debug level set to 4 there is no indication or any specifics on why it fails.
I loaded your fake camera .xml to our camera and it still reported FAILURE.
Can you point me to the code that evaluates SUCCESS or FAILURE for this test?
