But when I installed the L4T-Base container for R35.5.0 (per this) and installed accelerated gstreamer, I did not get the expected new properties in any elements. Here is what I get in my R35.5.0 container:
The OP in that thread had to recompile gstnvarguscamerasrc.cpp from source to get those. Ideally I would like to just download the latest package from the repos here rather than building from source, because I would like to test quickly to see if it solves my problem.

Unfortunately I am unable to find that in the Docker container.
Maybe the updated version of the dpkg is available in the downloadable BSP tbz2, but not updated in the APT repo?
To be sure that it wasn’t an issue with my Dockerfile, I also tried with R35.4.1 because that is also supposed to have the updated source (with the “acquire-wait” property in nvarguscamerasrc). R35.4.1 does have an official Docker tag in L4T-Base containers, unlike R35.5.0:
docker pull nvcr.io/nvidia/l4t-base:35.4.1
But I got the same issue. The “acquire-wait” property is missing, it should be the first property:
I think I’ve figured it out. It’s not possible to do in a Docker container on Jetson because the L4T-Base Docker will actually link to the host libraries. In my case, the host Jetson version is R35.3, so the new property are absent in those libraries “within” the container.
Presumably, running the rootfs in l4t-base:35.4.1 (including the install of nvidia-l4t-gstreamer) natively on the Jetson will yield the correct versions of packages, but I will test that later.
