MoviePy error : failed to read the first frame of video file... That may also mean that you are using a deprecated version of FFMPEG

I tried updating ffmpeg and moviepy. I even tried different versions but to no avail. The video clips are not corrupted as I checked.


This part of the code is responsible for generating the videos :


def generate_video(audio_path):
 input_folder = '/home/AlisterK/video_clips' # Replace with your folder path
 output_file = '/home/AlisterK/output_combined_video.mp4'
 clip_duration = 3 # Duration of each clip in seconds
 num_clips = 10 # Number of video clips to select and combine

 width = 1080 # Replace with your desired width
 height = 1920 # Replace with your desired height

 video_clips = random_files_in_folder(input_folder, '.mp4', num_clips)

 clips = [VideoFileClip(os.path.join(input_folder, clip_file)).subclip(0, clip_duration) for clip_file in video_clips]
 standardized_clips = [clip.resize((width, height)) for clip in clips] # Ensure consistent resolutions

 final_clip = concatenate_videoclips(standardized_clips)

 final_audio = AudioFileClip(audio_path)

Frames from Video Using OpenCV in Ubuntu with Java 17
2 août 2023, par bstrdnI've been trying to extract frames from a video using OpenCV in an Ubuntu environment with Java 17, but all my attempts have been unsuccessful so far. The main issue is that ffmpeg is not detected by the OpenCV library on ubuntu.


Here's my test code :


Main class


import org.opencv.core.Core;
import org.opencv.videoio.VideoCapture;

public class Main {
 public static String videoPath = "";
 static {
 String osName = System.getProperty("os.name").toLowerCase();
 if (osName.contains("win")) {
 System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
 videoPath = ClassLoader.getSystemResource("video.mp4").getPath();
 } else {
 videoPath = "/video.mp4";
// System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
 System.load("/usr/lib/opencv_java470.so");
 }
 }

 public static void main(String[] args) throws InterruptedException {
 VideoCapture videoCapture = new VideoCapture(videoPath);
 if (!videoCapture.isOpened()) {
 System.out.println("Error opening video file.");
 } else {
 System.out.println("Everything is fine.");
 }
 System.out.println(Core.getBuildInformation());
 Thread.sleep(1000000000000000000L);
 }
}

How can i fix this ? I'm deathly tired(


Thank you in advance for your assistance !


First I tried installation following the official instructions.https://github.com/bytedeco/javacv#required-software


Then the solution provided in https://stackoverflow.com/a/76750478/8087508,


but the result is the same.
