Can not open file by videoio::VideoCapture::from_file when chinese characters in filename on Windows 10 #544

Open ayang opened 4 months ago

ayang commented 4 months ago
  1. Operating system Windows 10
  2. I installed Opencv by vcpkg
  3. OpenCV version 4.8.0
  4. rustc version rustc 1.75.0 (82e1608df 2023-12-21) 
    let mut cap = videoio::VideoCapture::from_file("d:\\中文文件名.mp4", videoio::CAP_ANY)?;
let opened = videoio::VideoCapture::is_opened(&cap)?;

    Then the opened == false

The codes can be compiled, but can't open the file, if I change the filename to an english name, it will be ok. I guess it's an encoding problem.

This can happen if your filesystem encoding is not utf-8. I'm going to try to investigate this, maybe there is a solution for this. Thanks for reporting!
