We have encountered a problem using libargus that we did not expect to see. We have two imx274 color cameras working in our own application using the argus library. We are using a TX2 running 28.2.1.
We have recently added a third thermal camera, using a TC358746 bridge chip to interface it with the Jetson TX2. We have added our own driver based on IMX185 example. (Before you ask, camera binds correctly without errors according to media-ctl and v4l2-compliance). We can capture, process and display video from the new camera using the v4l2 library. We are having no trouble with this camera.
However, our imx274 application which has been running fine for months now, no longer works. The “camera provider” part of libargus has a conniption and refuses to run, even when we unplug the new camera. We can access the raw video from the original IMX274 cameras using v4l2-ctrl, so they are still fine. Argus_camera also refuses to run on either of the imx274 cameras. After looking into similar problems on the forum, we set this camera up to have a pixel type of SRGGB8, even though it is actually a RAW8. This should keep it compatible with the format limitations of the tegra multimedia suite. However, that did not change libargus behavior.
The simplest solution for us would be to tell libargus and its camera provider to ignore this new camera. So… is there a way to tell libargus to ignore a camera, perhaps through the override file or some other configuration file? We hope it can be something simple like this, as we have a tight delivery deadline.
Thanks for your help.
