ContrasTech Mars640-815uc support

[AjayGarad]

Hi, I have contrastech mars 640-815UC camera(USB 3.0). When I "run - arv-tool-0.6" I got the following answer: ContrasTech-3D02158AAK00012 (USB3)

then I run "arv-tool-0.6 features" and I got the following error:

ContrasTech-3D02158AAK00012 (USB3) (arv-tool-0.6:16863): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed (arv-tool-0.6:16863): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed Device 'ContrasTech-3D02158AAK00012' not found

I tried to run the "./arv-camera-test" but still got the same error:

Looking for the first available camera (lt-arv-camera-test:16846): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed No camera found

Can you tell why I am getting this error?

Please attach the output of:

arv-tool-0.6 features -d all:3

This is the output I got:

It looks like a permission issue.

Please try to run arv-test as root. If it works as root, then you can make the camera work as user by creating a udev rules file as described here: https://github.com/AravisProject/aravis#usb-permissions

[AjayGarad]

I did lsusb and copied the ID in the udev rule file and copied the file in the location "/etc/udev/rules.d" still getting error: "sudo arv-test-0.6" output: Testing device 'Mars640-815uc' from 'ContrasTech'

Could you attach the output with -d all:3 please.

[EmmanuelP]

The output of sudo arv-tool-0.6 -d all:3 features I mean.

[AjayGarad]

After running this: ~/software/aravis-0.5.10/tests$ sudo arv-tool-0.6 -d all:3 features

I got the following output:

I don't understand what goes wrong. It doesn't look like a permission issue. It is perhaps a configuration issue, when aravis tries to establish the connection to the device.

Did you try to connect to the camera using the manufacturer iCentral software ? (see issue #123)

[AjayGarad]

Yes I tried with iCentral software, it was working.

[madMAx43v3r]

I got similar errors when opening multiple USB3 cameras from different threads in parallel. The reason is the USB3 interface code is not thread-safe (all the functions that operate on the ArvUvInterface static singleton instance). To solve the issue I added a mutex in my code around calling arv_camera_new(...). So maybe this is also a multi-threading issue.

[EmmanuelP]

@madMAx43v3r It would be nice if you could open a new issue explaining what you have seen, and which part of ArvInterface you think is not thread safe.

Thanks.

[EmmanuelP]

@AjayGarad Did you finally succeed in connecting to your camera ?

[madMAx43v3r]

@EmmanuelP Looks like you made it thread-safe on May 29 with commit 520bcc8560f412c01337835c7391f662f9bd6944

[EmmanuelP]

Long time, no new. I'm closing this issue. Don't hesitate to reopen if you have the requested information.
