pythonw do nothing (ffmpeg problem?)

[Vegeta4567]

Hello,

I tried to follow the steps described in https://github.com/adamspierer/FreeClimber/blob/master/TUTORIAL.md

I am pretty sure I followed all the instructions, but when I try to run:

(python36) C:\Users\myUser\Desktop\free\FreeClimber>pythonw .\scripts\FreeClimber_gui.py --video_file .\example\w1118_m_2_1.avi

Is does absolutely nothing. I tried to redirect the output in a file, and I have this. I installed ffmpeg, added to the environment variables, but I am stuck. Do you have an idea?

Thanks a lot for your help and best regards!

Hi @Vegeta4567,

It is likely an issue with the installation of FFmpeg. Could you try to install it manually from https://ffmpeg.org/ , restart your computer, and try again?

Otherwise, can you help me with the following in order:

1. What version of Python are you running? Others have found issues when the Python version is incompatible. That said, the virtual environment should make that a non-issue if you are running in it. If you are using the virtual environment then move onto 2.
2. Does the non-GUI version of the script work with the test files? This will tell me if wxPython is the issue or the installation of FFmpeg.
3. Could you re-run the GUI and non-GUI versions of the script with the --debug tag as well? That will tell me which lines are unhappy and ideally it is the same part of the script for both.

Try this and let me know how things go!

Hello,

Thanks for your fast reply!

I am using Python 3.6.0 in the virtual env. 3.6.10 in the base (same problem):

I reinstalled ffmpeg. ffmpeg -version gives: ffmpeg version 6.0-essentials_build-www.gyan.dev Copyright (c) 2000-2023 the FFmpeg developers

The versions: argparse = 1.1 ffmpeg-python = 0.2.0 matplotlib = 3.1.3 numpy=1.19.5 pandas=1.0.5 pip=20.1.1 scipy=1.5.0 trackpy=0.4.2 wxPython = 4.0.4

If I run: pythonw .\scripts\FreeClimber_main.py --video_file .\example\w1118_m_2_1.avi it's the same problem. I suppose it's the non-GUI right?

I am not really familiar with Python, where I put the --debug command?

Thanks a lot and best!

The debug command would go at the end of when you call the script: pythonw .\scripts\FreeClimber_main.py --video_file .\example\w1118_m_2_1.avi --debug

To run the non-GUI, try this as well: python FreeClimber_main.py --config_file ./example/example.cfg --debug

Hello,

The first command returns absolutely nothing.

For the second one, I have this result:

Hello,

For me, the problem was the virtual env.

I have totally uninstalled python and anaconda. Reinstalled anaconda Installed python 3.6.8 https://www.python.org/ftp/python/3.6.8/python-3.6.8-amd64.exe Reboot the computer Launched a anaconda console Installed the dependencies needed. pip install argparse pip install ffmpeg-python pip install matplotlib pip install numpy pip install pandas pip install scipy pip install trackpy pip install wxPython pip install FreeClimber

And it works :-)
