Green Screen when launching yolox_ros_py

[JonathanNash21]

I will add that I edited the dockerfile to be pull from dustynv/ros:galactic-ros-base-l4t-r32.7.1, I wouldn't think this would cause issues with building though

I think the issue might be with v4l2 or CvBridge, but I'm not entirely sure. Is there an easy way to apply GStreamer instead?

If you think v4l2-camera is the cause, then I don't think this issue comes from Jetpack. rqt_graph should see if it shows the screen.

Checking that the YOLOX demo.py works correctly in the container would be a good way to get some hints. Please give it a try.

Sorry, I should've gotten back to this earlier - I fixed the issue by changing the pipeline to use GStreamer through a combination of using https://github.com/BrettRD/ros-gst-bridge instead of v4l2-camera as the webcam node in the launch file (not sure if this does anything important due to the next thing) and then using a gstreamer pipeline via OpenCV to open the camera in yolox_ros.py, which I convert to a ROS message via the CvBridge to be able to publish the video frames.
