Hello, I am having some issues using zedsrc in a gstreamer pipeline.
This is my build information:
-result from lsb_release -a:
Distributor ID: Ubuntu
Description: Ubuntu 18.04.6 LTS
Release: 18.04
Codename: bionic
-Nvidia Jetson Xavier NX
-Jetpack4.6
-ZED2i Camera
The Problem:
I am having trouble getting the camera to work in my pipeline (run in a c++ program) after upgrading to ZED 3.7.7 from 3.7.2. When running my custom pipeline, zedsrc seems to not publish any frames to my pipeline and it just idles and instead just streams an image of my desktop environment to the sink display. It does however work when making a sample pipeline using the command line like
gst-launch-1.0 zedsrc ! autovideoconvert ! queue ! xvimagesink or by recreating that pipeline within my c++. If I downgrade back to 3.7.2, my pipeline works as expected. The only common element that I see here is the upgrade between ZED APK versions as nothing else in my pipeline has changed. Has something changed in between 3.7.2 and 3.7.7 that would explain this?
Additional Information
This is the output that occurred when I upgraded using ./ZED_SDK_Tegra_L4T32.6_v3.7.7.run:
Verifying archive integrity... 100% MD5 checksums are OK. All good.

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
uff 0.6.9 requires protobuf>=3.3.0, but you have protobuf 3.0.0 which is incompatible.

To install it later or on a different environment run :
python -m pip install --ignore-installed /tmp/selfgz24462/pyzed-3.7-cp36-cp36m-linux_aarch64.whl
The ZED Python API was installed for 'python3', when using conda environement or virtualenv, the ZED Python API may need to be resetup to be available (using 'python /usr/local/zed/get_python_api.py')
/sbin/ldconfig.real: File /usr/local/lib/libjetson-utils.soi is empty, not checked.
Please note that installing the 'libv4l-dev' apt package at any point on jetson will break the hardware encoding/decoding support

I then recompiled the ZED Gstreamer library using the instructions at GitHub - stereolabs/zed-gstreamer: GStreamer source plugin for ZED Cameras
and received the following output:
