Closed Mohawker47 closed 3 weeks ago

Mohawker47 commented 2 years ago

Full error message returned when using code from: "setting up a camera configuration for processing a single video" and "open movie and plot a single frame" from pyorc 0.2.3 documentation

@Mohawker47 sorry that we missed this issue. Can you let us know the status? It looks like the video file doesn't exist. Can you check if the path was set correctly?

hcwinsemius commented 1 year ago

A more clear message is needed on possible non-existing files than the default opencv message (0 FPS).

I too currently have this issue.

I first ran into the problem with my own .mp4 file but also have the same error with examples_camera_calib_camera_calib_720p.mkv dk_control.mp4

Has any attention been given to this issue?

Reaching out about this issue.

The path to the video file is set correctly. I have updated, uninstalled, and installed both opencv and pyopenrivercam (and its dependencies).

For more context, I have installed pyorc using both conda and mamba and each for python versions 3.8 and 3.10. In each case I have also installed in a virtual environment and without and still cannot read in video file without a returned FPS = 0.0. I have also tried this using three different video files.

Is there a preferred python version that should be used? Thank you for the time.
