Am trying to run the Intel OpenVino Multi Camera Multi Target python demo on Raspberry Pi 4.
Have installed all the requirements (I believe) but when I run the script I get the following warning and therefore no video is processed.
[ WARN:0] global ../opencv/modules/videoio/src/cap_gstreamer.cpp (2041) handleMessage OpenCV | GStreamer warning: your GStreamer installation is missing a required plugin
[ WARN:0] global ../opencv/modules/videoio/src/cap_gstreamer.cpp (2057) handleMessage OpenCV | GStreamer warning: Embedded video playback halted; module uridecodebin0 reported: Your GStreamer installation is missing a plug-in.
[ WARN:0] global ../opencv/modules/videoio/src/cap_gstreamer.cpp (1034) open OpenCV | GStreamer warning: unable to start pipeline
[ WARN:0] global ../opencv/modules/videoio/src/cap_gstreamer.cpp (597) isPipelinePlaying OpenCV | GStreamer warning: GStreamer: pipeline have not been created
Any assistance or guidance in this regard would be most helpful.
Thank you for reaching out to us.
Please make sure corresponding GStreamer plugins (gstreamer1.0-plugins-good, gstreamer1.0-plugins-bad, gstreamer1.0-plugins-ugly) are installed. You can have a check by executing the following command:
apt list -i | grep gstreamer
Also, please try to install ffmpeg with the following command:
sudo apt install ffmpeg
On another note, to run multi_camera_multi_target_tracking_demo.py, --m_reid command is required. However, all these person-reidentification-retail models are not supported by VPU.
Intel’s Pre-Trained Models Device Support is available at the following page:
This thread will no longer be monitored since we have provided suggestions.
If you need any additional information from Intel, please submit a new question.
@Duggy The table referred by @Wan_Intel explains which models supported on listed devices (CPU, GPU and MyriadX). The reidentification models (person-reidentification-retail-0277, person-reidentification-retail-0286, person-reidentification-retail-0287, person-reidentification-retail-0288), according this table, were successfully validated on CPU and GPU, but not supported on MyriadX.
