Problem resolved running on:

Kernel: Debian 6.12.25-1+rpt1
hailo-all: 4.20.0
hailo-tappas-core: 3.31.0+1-1
hailofw: 4.20.0-1
rpicam-apps-hailo-postprocess: 1.7.0-1

Was unable to execute python pose_estimation.py, the video would not display and terminal would hang. Updating the following code fixed the issue:
Updated gstreamer_helper_pipelines.py

  • changed line number 110:
  • From:  f'video/x-raw, pixel-aspect-ratio=1/1, format={video_format}, width={video_width}, height={video_height} '

  • To:         f'video/x-raw, format={video_format} '

Also when running python pose_estimation.py --input rpi, this was unstable, would run several minutes to a few hours, but would then hang. After the following update, the code has been running for 9 hours with no issues, will continue to execute to validate stability.
Updated gstreamer_helper_pipelines.py

  • changed line number 85:
  • From:  f'video/x-raw, format={video_format}, width={video_width}, height={video_height} ! '
  • To: 'video/x-raw ! ’
