Hi,
The issue is underinvestigation. A quick solution is
$ sudo mv /usr/lib/aarch64-linux-gnu/tegra/libv4l2_nvargus.so /usr/lib/aarch64-linux-gnu/tegra/libv4l2_nvargus_back.so
So that libv4l2_nvargus.so will not be loaded. The following sample will be impacted:
/usr/src/jetson_multimedia_api/samples/unittest_samples/camera_unit_sample
If you don’t develop your use-case based on camera_unit_sample, please try this quick solution.
