Argus multiSensor sample fails even though single sensor demo apps work on JP3.1 w/IMX274

I’m using IMX274 modules from Leopard Imaging and their driver patches for JP3.1 for the TX1.

When patches applied, kernel built, and TX1 updated, nvgstcapture works when switching between sensors. I can open two instances of the argus_camera demo app with one for each sensor.

But when I run the argus_multiSensor demo app I get in /var/log/syslog

The demo app is supposed to show video to screen from one sensor and write other sensor to disk. The one that goes to screen goes gray. and program never ends. (and only 2 jpegs are written Argus_0000.jpg and Argus_0001.jpg, and they are black).

In our custom application, we are basing things off the GstVideoEncode and ArgusMultiSensor samples to have simultaneous streaming of multiple camera modules into our software for later processing and compression.

We see similar timeouts when we try to run with 2 cameras, with 1 camera our software runs as it did in earlier Jetpacks (2.4). With previous Jetpacks 2 cameras had no issue.

Are there changes required in how multiple simultaneous streams are handled with JP3.1? Is there a driver issue? It doesn’t seem to be driver related as the argus_camera apps running simultaneously show the video can be pushed through the system, but since its a time-out not totally sure.

Hi
There’s no problem on my side. The argus_camera have multi session support too. Does this sample app have problem to launch multi session too?

I had an issue in changing the device tree from 3 sensors to 2 (the sample does work with the 3 sensor device tree, but I’m currently using 2 senors/tegra so needed to modify it). Seems it was my changes to make it go to 2 that messed up the sample app.
