Fix windows video selection for extraction in the GUI

[KonradDanielewski]

QtWidgets.QFileDialog.getOpenFileNames outputs unix formated paths which on Windows leads to wrong reading and uninformative output "Video file corrupted" which isn't true. This fix normalizes the path according to os

@n-poulsen see you approved, but all tests are failing?

[n-poulsen]

They're failing due to the issue with scipy-1.11.1 (which is fixed as we pinned scipy). I'll merge the changes made to main and re-run the tests.

Hi there,
Based on the earlier conversations, I checked the component.py file and found correct. But I am still facing the problem with extracting frames from videos. Even though the pop-up appears instantly stating frames are extracted successfully, but the process did not run actually. On the prompt, it did not show any run command:

python -m deeplabcut

I am working on Windows 11, DLC 2.3.10, single animal, CPU.

Any help in this regard is greatly appreciated?

Hi @skd217 - have you been able to extract frames for any project, or does it always fail?

[skd217]

Hi @n-poulsen,
Unfortunately, it’s still not working. I also attempted converting the videos (originally in .mov format, recorded on an iPhone) into different formats (.mp4, .avi, etc.), but that didn’t resolve the issue either.

[n-poulsen]

Are you working with the GUI or with code? If you're working with the DeepLabCut GUI, could I ask you to run the commands to extract frames using python code, and let me know if any errors occur?

You can extract frames with code (as mentioned in our docs) by running ipython from your Anaconda prompt, and then running:

import deeplabcut

config_path = r"C:\path\to\DLC\project\config.yaml"
deeplabcut.extract_frames(config_path, mode="automatic", userfeedback=False)

Hi @n-poulsen Finally, I am able to extract the frames using ipython as suggested. Initially, I was struggling with GUI.
Thank you very much !!
