• YouTube-DL Python output file format not mp4

  16 septembre 2020, par Sushil

  I have written a small piece of code in python to extract either the audio or the video from a YouTube video. Here is the code :

  


  from __future__ import unicode_literals
import youtube_dl

link = input("Enter the video link:")

while True:
    choice = input("Enter a for audio file, v for video file:")
    if choice == "a" or choice == "v":
        break

ydl_opts = {}

if choice == "a":
    ydl_opts = {
        'format': 'bestaudio/best',
        'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3',
            'preferredquality': '192',
        }],
    }
    
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    info_dict = ydl.extract_info(link, download=False)
    video_title = info_dict.get('title', None)

if choice == "a":
    path = f'D:\\DwnldsYT\\{video_title}.mp3'
if choice == "v":
    path = f'D:\\DwnldsYT\\{video_title}.mp4'

ydl_opts.update({'outtmpl':path})

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([link])


  


  The audio extraction works fine, but the problem is with the video extraction. When I extract the video, I am getting the output as an mkv file, not an mp4 file. Any idea about how to save the video file as mp4 ?

  


• Converting a large number of MP3 files to videos for YouTube, each using same the JPEG image

  25 juin 2020, par David

  I am looking for a way to convert large number of MP3 files to videos, each using the same image. Efficient processing time is important.

  


  I tried the following :

  


  ffmpeg -i image.jpg -i audio.mp3 -vcodec libx264 video.mp4


  


  VLC media player played the resulting video file with the correct sound, but a blank screen.

  


  Microsoft Media Player played the sound and showed the intended image. I uploaded the video to YouTube and received the message :

  


  


  "The video has failed to process. Please make sure you are uploading a supported file type."

  


  


  How can I make this work ?

  


• Continuous YouTube live stream via ffmpeg keeps failing after a while [closed]

  23 octobre 2024, par dooleyo

  I am trying to stream a simple MP4 file as a 24/7 YouTube radio station on repeat from a virtual machine using ffmpeg. It's only a 23 minute ( 1GB) file, and runs fine for hours or even days, then hangs up. I've tried on a small Digital Ocean droplet and detaching the ssh session with screen. I am using -c copy so I don't need to process or re-encode anything (even on the smallest droplet, the memory/cpu utilization is negligible, so I know that's not the issue). I have even tried some of ffmpeg's auto-restart options to no avail. Here is the command I'm currently running :

  


  ffmpeg -stream_loop -1 -re -i file.mp4 -c copy -drop_pkts_on_overflow 1 -attempt_recovery 1 -recover_any_error 1 -recovery_wait_time 1 -f flv "rtmp://x.rtmp.youtube.com/live2/{STREAM_KEY}"

  


  This works perfectly, for a time, then hangs up with :

  


  aost#0:1/copy @ 0x623b201c5fc0] Error submitting a packet to the muxer: Broken pipe

  There are not many articles I've found covering the broken pipe issue, but those that do seem to involve either A) streams that won't start, or B) streams where the broken pipe occurs the first time the input tries to loop (neither of which are my problem, since it streams and loops fine for quite a while).

  


  Thanks in advance !
