i try to get the detection example to work on hailo 8l module.
(hailo_virtualenv) hailo@edge:/local/workspace/tappas/apps/h8/gstreamer/general/detection$ hailortcli fw-control identify

I exchanged the .hef from the detections script to match my module,
but for some reason I only get a mirror window of my screen and an error message.
My changes:
usage of yolov5m_wo_spp.hef from official site for 8l and renamed it accordingly to make it clear. → yolov5m_wo_spp_8l.hef
a_detection.sh ↔ detection.sh changes:
-
readonly DEFAULT_NETWORK_NAME=“yolov5m_wo_spp_8l.hef”
-
readonly DEFAULT_HEF_PATH=“$RESOURCES_DIR/yolov5m_wo_spp_8l.hef”
-
if [[ $input_source =~ “/dev/video0” ]]; then
