Stop processing video files.

General

Hello,

I use this project: GitHub - hailo-ai/hailo-rpi5-examples to make detection. how to stop processing when the script goes through all frames?

Now it show: “Video rewound successfully. Restarting playback…”.

I tried edit gstreamer_app.py in venv_hailo_rpi5_examples\site-packages\site-packages\hailo_apps_infra\gstreamer_app.py, but it looks like project doesn`t use this file.

I’m asking for help.

Hey @hubert12301,

You’re right, to prevent the video from looping and stop the execution when all frames have been processed, you need to modify the gstreamer_app.py file. Keep in mind that you might need to update this file every time you reinstall the examples.

Here’s how you can make the necessary changes:

  1. Locate the following function in gstreamer_app.py:
def on_eos(self):
    if self.source_type == "file":
        # Seek to the start (position 0) in nanoseconds
        success = self.pipeline.seek_simple(Gst.Format.TIME, Gst.SeekFlags.FLUSH, 0)
        if success:
            print("Video rewound successfully. Restarting playback...")
        else:
            print("Error rewinding the video.", file=sys.stderr)
    else:
        self.shutdown()
  1. Modify the function to stop the execution instead of looping:
def on_eos(self):
    print("End-of-stream reached. Exiting...")
    self.shutdown()  # Stop the pipeline and exit gracefully
