arv-camera-test-0.10 fails for ContrasTech Mars 800-200gc (GigE Vision) – Packet size 0, stream creation fails

[abhi-sensoviz]

Describe the bug
Multiple acquisition and single acquisition tests fail for the ContrasTech Mars 800-200gc camera. Errors indicate GigEVision write_memory error (invalid-parameter) and missing timestamp information.

Example output from arv-camera-test-0.10:

Looking for the first available camera
vendor name            = ContrasTech
model name             = Mars 800-200gc

gv packet size         = 0 bytes
Can't create stream thread: [ArvGevSCPSPacketSize] [ArvGevSCPSPacketSizeReg] GigEVision write_memory error (invalid-parameter)

To Reproduce
Steps to reproduce the behavior:

1. Run the test:

arv-camera-test-0.10

3. Or run your own program (main2.cpp) using Aravis:

./main2
Using camera: ContrasTech-Mars 800-200gc-3C04215PAK00002
Can't create stream: [ArvGevSCPSPacketSize] [ArvGevSCPSPacketSizeReg] GigEVision write_memory error (invalid-parameter)

Expected behavior

• Stream thread should be created successfully.
• Packet size should not be 0 bytes.
• Multiple and single acquisition tests should pass.

• Manufacturer: ContrasTech
• Model: Mars 800-200gc
• Interface: GigE Vision

Platform description:

• Aravis version: 0.9.1 (also tested 0.8.35)
• OS: Ubuntu 20.04
• Hardware: x86_64

Additional context

• Camera works with MVViewer.
• Failures occur during ArvGevSCPSPacketSize writes.

Hi,

It would be interesting to know where this line is emitted:

** (arv-camera-test-0.10:13510): CRITICAL **: arv_gc_integer_get_value: assertion 'error == NULL || *error == NULL' failed

Could you get a backtrace using gdb and running arv_camera_test with G_DEBUG=fatal-warnings ?
