So, I want to ask the basic problem for this...Thank you!

@XuTZ0912 jpeg is true or false flag. when included it in the argument it would be True otherwise it is False.

The way to use is python3 pose_camera.py --jpeg

Which camera are you using? If USB camera can you share the output of v4l2-ctl --list-formats-ext --device /dev/video1

Feel free to reopen if they are any questions on this issue.

@hjonnala The help says

--jpeg                Use image/jpeg input

but how do you pass the image, if it is a boolean flag? If I use --videosrc I get a similar issue as #85

$ python3 pose_camera.py --jpeg --videosrc image.jpg

Hi @maiermic for single image please try simple_pose.py.
jpeg flag is used to modify the gstreamer pipeline. It still required camera input as video source.

[maiermic]

@hjonnala I'd like to get a drawing of the pose (e.g. like pose_camera.py). simple_pose.py only prints the coordinates.

please try replacing the sinple_pose.py with the script at: https://github.com/hjonnala/snippets/blob/main/posenet/simple_pose.py

@hjonnala Thank you 👍
