• How to resolve Electron ffmpeg error opening input file ?

  26 août 2023, par 3V1LXD

  I have an Electron app with ffmpeg.exe inside the project's bin folder. When i try to use ffmpeg to make a new video I get an error reading the input file.

  


  FFmpeg error: [in#0 @ 000002667f2ab9c0] Error opening input: No such file or directory

Error opening input file C:/Users/xxxx/Videos/Powder/2023.08.19%2017.30.37_Apex_Legends/Powder_2023.08.19%2021.00.48.mp4


  


  const ffmpeg = spawn(ffmpegPath, [
  '-i', videoFile,
  '-filter_complex', filterComplex,
  '-map', '[out]',
  '-c:v', 'libx264',
  '-crf', '18',
  '-preset', 'veryfast',
  '-y',
  path.join(outputDir, outputName)
]);

ffmpeg.stdout.on('data', (data) => {
  console.log(`FFmpeg output: ${data}`);
});

ffmpeg.stderr.on('data', (data) => {
  console.error(`FFmpeg error: ${data}`);
});

ffmpeg.on('close', (code) => {
  console.log(`FFmpeg process exited with code ${code}`);
  event.reply('ffmpeg-export-done'); // Notify the renderer process
});


  


  How can i resolve this path issue ?

  


• FileNotFoundError when extracting audio from recently saved video using FFMPEG"

  3 août 2023, par Peter Long

  Scenario : I'm using this tool to record tiktok live. I write another script to call the main.pytool because I want to add some additional options, for example, to extract the audio of the live video that is recorded
  

  


  FFMPEG is used to extract the audio. First the video is saved (with FFMPEG) and after I want to extract the audio of that video (again with FFMPEG). The path where the video is recorded and saved is C:\Users\Administrator\Desktop\tiktok

  


  The problem is that I see the file and it is saved, but this error is generated as output : FileNotFoundError: [WinError 2] The system cannot find the file specified

  


  I can't figure out why it doesn't detect the last saved video file in general

  


  I try with this

  


  import os
import subprocess
import time
from moviepy.editor import VideoFileClip

def main():
    # Command to run main.py and record the video
    cmd = 'python main.py -user ryzebenny -output "C:\\Users\\Administrator\\Desktop\\tiktok" -ffmpeg -duration 30 --auto-convert'
    subprocess.run(cmd, shell=True)

    # Wait for the video file to appear in the folder
    wait_for_video("C:\\Users\\Administrator\\Desktop\\tiktok")

    # Extract audio from recorded video
    video_filename = find_latest_file("C:\\Users\\Administrator\\Desktop\\tiktok", ".mp4")
    if video_filename:
        video_path = os.path.join("C:\\Users\\Administrator\\Desktop\\tiktok", video_filename)
        audio_filename = video_filename.replace(".mp4", ".mp3")
        audio_path = os.path.join("C:\\Users\\Administrator\\Desktop\\tiktok", audio_filename)

        video_clip = VideoFileClip(video_path)
        audio_clip = video_clip.audio
        audio_clip.write_audiofile(audio_path)
        audio_clip.close()
        video_clip.close()
        print(f"Audio extraction completed: {audio_filename}")
    else:
        print("No video files found.")

def wait_for_video(directory):
    max_wait_time = 60  # Maximum time to wait in seconds
    start_time = time.time()
    while time.time() - start_time < max_wait_time:
        if find_latest_file(directory, ".mp4"):
            break
        time.sleep(1)

def find_latest_file(directory, extension):
    list_of_files = [f for f in os.listdir(directory) if f.endswith(extension) and os.path.isfile(os.path.join(directory, f))]
    if list_of_files:
        return max(list_of_files, key=os.path.getctime)
    return None

if __name__ == "__main__":
    main()


  


  but i get this error

  Instead, I expect that once I save the video (in .mp4) the audio of that video will be extracted afterwards

  


• Installing FFMPEG on my EC2 instance takes too long ; what am I doing wrong ? [closed]

  24 août 2023, par Shaban Khawar

  I found a good article on how to download onto my EC2 instance : link
Here's the issue. It takes forever ! It takes around 15 minutes to install.

  


  I'm running my EC2 instance on Amazon Linux 2023, so no apt-get for me.
Also my EC2 instance is created by my EB environment, so if auto-scaling occurs, my instance will be terminated and a new one will be created. I can set .ebextensions to run all the commands to install FFMPEG again but as mentioned above, it takes forever ! That means for 15-20 minutes, my server is down because of one dependancy. I feel like I'm going about this the wrong way, so any advice is appreciated.
