Description

Hello

There is a slow memory leak in the ZED gstreamer plugin. I did a simple test where I ran the following command:

gst-launch-1.0 zedsrc name=psrc camera-fps=15 camera-resolution=4 enable-imu-fusion=true enable-positional-tracking=true depth-minimum-distance=500 depth-mode=1 fill-mode=false camera-sn=43566715 stream-type=4 ! fakesink

with three such ZED X cameras, and I monitored the RAM usage over time. After about 1 hr and 15 mins, both RAM(16GB) and Swap space(8GB) on my Jetson Orin NX was filled up, with no other applications running. The baseline ram usage without these apps running was about 2GB.

Here with attached is a screenshot of the run, and my ZED Diagnostics output.

1. Run the command gst-launch-1.0 zedsrc name=psrc camera-fps=15 camera-resolution=4 enable-imu-fusion=true enable-positional-tracking=true depth-minimum-distance=500 depth-mode=1 fill-mode=false camera-sn=43566715 stream-type=4 ! fakesink
2. Monitor RAM usage over time. Recommended to run this this command across multiple cameras.

Expected Result

RAM usage should stay stable and not consume all of the available memory even after running the plugin for hours on end.

Actual Result

No more available memory. System crashes.
