Encoder GFX errors

I am trying to run the encoder to compress my video stream. The v4l2_camera node outputs the video stream in RGB8 format with a resolution of 1920x1080 pixels. This is the complete log when running the encoder:

Start with the isaac_ros_h264_encoder.launch.py entry point and the supplied encoder log, focusing on the v4l2_camera RGB8 1920x1080 input and the repeated receiver-pointer warnings. Determine why this stream is not processed and verify that the encoder runs without those errors.
