Problems with VideoFileClip() at the moment of audio processing

[kaynshae]

I ran into a problem, I process a large number of videos, but on some videos the script just gets up and does nothing. I wondered why this is so?

As a result, the problem is in the line(everything is running before it):
s = self.proc.stdout.read(L) in read_chunk() readers.py . It just doesn't output anything.

The bottom line is that videos that have sound, process everything correctly, then I started testing videos that don't have sound, for some reason self.reader.infos['audio_found'] == True. Because of this, audio editing is being launched. Then everything is fine, the result is self.proc =={'bufsize': 200000, 'stdout': -1, 'stderr': -1, 'stdin': -3, 'creationflags': 134217728}, the same as in a normal video. self.proc.stdout == <_io.BufferedReader name=6> as in a normal video, but when another read() element is added, the script just freezes.

I couldn't come up with a solution. So I'm informing you about it.

I understand that this is most likely a problem with the file itself. Since the properties of the video file display the audio stream rate and so on. Although in fact there is no sound.

But, I need some more checking, waiting, I don't know. If, for example, there is no response within 3 minutes, the script throws an error.

Fixed the problem via timeout. Checking the validity of the file via VideoFileClip. If no response has been received within 10 seconds, it ends.

import multiprocessing
import time
from moviepy.editor import VideoFileClip, CompositeVideoClip
import sys

def process_video_clip(video):
    dir_movies = r"D:\AutoMaterial Random\videos"
    with VideoFileClip(dir_movies + "\\" + video) as main_clip:
        sum = 1

if __name__ == '__main__':
    video = sys.argv[1]
    p = multiprocessing.Process(target=process_video_clip, args=(video,))
    multiprocessing.freeze_support()
    p.start()

    # We wait 10 seconds or until the process is completed
    p.join(10)

    if p.is_alive():
        print("Stop process")
        p.terminate()
        p.join()
        with open("file.txt", "w") as file:
            file.write("False")
            print("write False")
    else:
        with open("file.txt", "w") as file:
            file.write("True")
            print("write True")

Thank you for your contributions and for reporting issues in this repository. With the release of v2, which introduces significant changes to the codebase and API, we’ve reviewed the backlog of open PRs and issues. Due to the length of the backlog and the likelihood that many of these are either fixed or no longer applicable, we’ve made the decision to close all previous PRs and issues.

If you believe that any of these are still relevant to the current version or if you'd like to reopen a related discussion, please feel free to create a new issue or pull request, referencing the old one.

Thank you for your understanding and continued support!
