Error opening video file in OpenCV 4.8.0
benjamingb opened this issue · comments
Hi
After manually compiling OpenCV 4.8.0, I encountered an issue where it fails to read video files. I consistently receive an error message indicating that the video cannot be opened. Any insights or suggestions to resolve this problem would be greatly appreciated
This is the output when I compile opencv
That's what I'm trying to call it.
pub fn get_video_capture(video_src: &str, typ: String) -> VideoCapture {
if typ == "rtsp" {
let video_capture = match VideoCapture::from_file(video_src, CAP_ANY) {
Ok(result) => {result},
Err(err) => {
panic!("Can't init '{}' due the error: {:?}", video_src, err);
}
};
return video_capture;
}
let device_id = match video_src.parse::<i32>() {
Ok(result) => {result},
Err(err) => {
panic!("Can't parse '{}' as device_id (i32) due the error: {:?}", video_src, err);
}
};
let video_capture = match VideoCapture::new(device_id, CAP_ANY) {
Ok(result) => {result},
Err(err) => {
panic!("Can't init '{}' due the error: {:?}", video_src, err);
}
};
return video_capture;
}
let mut video_capture = get_video_capture(&settings.input.video_src, settings.input.typ.clone());
let opened = VideoCapture::is_opened(&video_capture).map_err(|err| AppError::from(err))?;
if !opened {
return Err(AppError::VideoError(AppVideoError{typ: 1}))
}This is the output when compiling with cargo build -vv
Environment
OS: Ubuntu 24.04
rustc: 1.77.2
The OpenCV build log looks fine, it picked up ffmpeg. Can you maybe check if the corresponding Python or C++ program linked against the same manually build of OpenCV works or fails in the similar fashion?
I tried in c++ and the same problem appears, I think it is an opencv problem
Looks like it then, maybe for RTSP support you need some additional dependencies?
I compiled again with the minimum configurations and it worked, the strange thing is that I did not enable FFMPEG
