• Dailymotion Video Url to Audio Downloader

  27 août 2020, par Maisum Abbas

  I am trying to create Dailymotion Video URL to Audio Downloader. Since I have to deploy it on Firebase, I will have to use JavaScript, hence node.js. I have tried various approaches by following different links but didn't find anything that works for me. Most of them are based on terminal from where they can run which I don't require including ffmpeg. One ffmpeg tutorial I found was based on uploading videos and then converting it to audio which didn't work with the URL. Also, I didn't find any code from where I can use or read to manage ffmpeg in code, just found the guide of how to use it in terminal. So can anyone guide me where I can get a useful link that can help me. I have tried on GitHub as well. Really hoping to get help from here.

  


• whats the difference between “&” and multiple terminals in Linux Multiprocessing [closed]

  11 mai 2022, par Ma XIaoyu

  I am using Linux for multi-task processing. Specifically, calling ffmpeg multiple times to transcoding multi source videos.

  


  Strangely, when I am using :
“
ffmpeg-cmds01 &
ffmpeg-cmds02 &
ffmpeg-cmds03 &
……
”
The ffmpeg process often get errors and stop after a few hours.

  


  However, if I open several terminals and using each terminal for only one ffmpeg cmd( i.e., terminal#1 only run ffmpeg-cmd01 ; ternimal#2 only for ffmpeg-cmd02, etc.) The transcoding procedure can last for dozens of days and no errors are reported.

  


  Could anyone kindly help us to analysis what’s there differences ? Opening multiple terminals is too difficult for managing especially when the number of video streams are up to 300+.

  


  Thanks a lot for help !

  While converting files HEVC to mp4 using python the error is comming by ffmpeg. I have used moviepy to convert video to mp4 formate.

  


  Used moviepy Package to convert but throwing error

  


  import os
from moviepy.editor import VideoFileClip

def convert_to_mp4(input_file, output_file):
    try:
        clip = VideoFileClip(input_file)
        codec = 'libx264'  # Default codec is libx264
        if clip.reader.codec_name == 'hevc':
            codec = 'libx265'
        clip.write_videofile(output_file, codec=codec, audio_codec='aac')
        return True
    except Exception as e:
        print(f"Error converting video: {str(e)}")
        return False

def upload_and_convert(input_file_path, output_folder):
    if os.path.exists(input_file_path):
        # Convert to MP4
        mp4_file_path = os.path.join(output_folder, 'converted2.mp4')
        success = convert_to_mp4(input_file_path, mp4_file_path)

        if success:
            print(f"Conversion successful. MP4 saved at {mp4_file_path}")
            return mp4_file_path  # Return the path of the converted MP4 file
        else:
            print("Failed to convert the video.")
            return None
    else:
        print("Input file not found.")
        return None

input_file_path = '/Downloads/sample-hevc-file.hevc'
output_folder = '/Downloads'
download_link = upload_and_convert(input_file_path, output_folder)

if download_link:
    print(f"Download the converted MP4 file here: {download_link}")
