Not able to run pose_camera.py on a video

[pakcodee]

Description

l am trying to run this following command on the dev board

mendel@silly-llama:~/project-posenet$ python3 pose_camera.py --videosrc BenVid.MOV

The goal is to map out the poses of the people in the video but l am getting this error, does anyone have an idea of what could be missing? l am running headless connecting via mdt shell and downloaded fresh project repo without any changes.

I'm having the same issue too. I'm trying to just process a video on the devboard, but there are no examples of processing videos in the repo---just processing via cameras.

Hello @pakcodee project-posenet repo has not been implemented to accept .mov files. Please try changing this line as below to accept .mov files. Thanks!

    if '.MOV' in videosrc.upper():
        PIPELINE = f'filesrc location={videosrc} ! qtdemux name=demux  demux.audio_0 ! queue ! decodebin ! audioconvert ! audioresample ! autoaudiosink   demux.video_0 ! queue '
    else:
        PIPELINE = 'v4l2src device=%s ! {src_caps}' % videosrc

After adding that line of code and running this is what the output is, the same as before but without the errors
