• Simple Question About Subprocess popen + screen +ffmpeg + youtube-dl

  2 juin 2021, par El_Barto_404

  ffmpeg -i "$(youtube-dl -x -g "https://youtu.be/xhXq9BNndhw")" -f s16le -ac 2 -ar 48000 -acodec pcm_s16le input.raw


  


  can anyone put this inside a popen process after a screen -S Convert ?

  


  I tried already with ' ', with commas.. but nothing

  


  I built a bot on telegram which if you send :

  


  .mandala youtubelink


  


  it takes the link and converts the video from YouTube into a uncompressed file, I need it for a music bot which streams those uncompressed files.

  


  if I run in console :

  


  ffmpeg -i "$(youtube-dl -x -g "https://youtu.be/xhXq9BNndhw")" -f s16le -ac 2 -ar 48000 -acodec pcm_s16le input.raw 


  


  it works but when I try with screen and popen it doesn't.. why ?

  


  @helper.register(pattern=r'.mandala (.+)')
async def mu2342sicbfffffffot(e):
    cheater = e.pattern_match.group(1)
    cheat = cheater
    myorder2224 = ''' "$(youtube-dl -x -g "{}")" '''
    doit = (myorder2224.format(cheater))

    ###  I already try to format the variable 
    ###  and put doit after -i and 
    ###  everything was in '' and commas 
    ###  like 'ffmpeg', 'i*, doit, '-f'...
    ###  and so on but nothing.. but nope doesn't work.

    p = subprocess.call(['screen','-S','onveter',' ffmpeg -i "$(youtube-dl -x -g "https://www.youtube.com/watch?v=Sw5HQbYGoCA")" -f s16le -ac 1 -acodec pcm_s16le -ar 96k  input.pcm'],shell=True)
  await helper.control_panel.send_message(config.chat, "La sto a manna")
  time.sleep(14)
  


  


  I REPEAT ONE MORE TIME :
HOW CAN I USE THAT FFMPEG COMMAND INSIDE A POPEN SUBPROCESS AFTER A Screen -S Convert ?

  


  IF SOMEONE WANT TO KNOW WHY :
Because I want to convert youTube videos to file .raw / .pcm

  


• Download a part of youtube video using a powershell script

  26 octobre 2024, par Nguyễn Đức Minh

  I'm writing this Powershell script :

  


  $URL = "https://www.youtube.com/watch?v=KbuwueqEJL0"
$from = 00:06:15
$to = 00:09:17

$cmdOutput = (youtube-dl --get-url $URL) 

ffmpeg -ss $from -to $to -i  -ss $from -to $to -i  output.mkv


  


  This script's purpose is to download a part of a Youtube video. I've set the variable $URL to specify the Youtube URL, while $from and $to is the start and end time of the part I want to download.

  


  $cmdOutput is used to output the stream URL. The output would have two lines : the first one is the URL for the video stream, while the second one is the audio stream URL.

  


  Currently, I don't know how to use the output as a variable and specify the line number of $cmdOutput to put it into the correct stream. I guess and would be replaced by something like $cmdOutput[line 1], and $cmdOutput[line 2], though I know that those are incorrect.

  


  I've consulted this answer, and it is handy for me to write this script. I've also read Boris Lipschitz's answer on how to do the same thing with Python, but his answer does not work.

  


  In that script, the -ss flag inputs the seeking point, and the -t <duration></duration> flag tells FFmpeg to stop encoding after the specified duration. For example, if the start time is 00:02:00 and the duration is 00:03:00, FFmpeg would download from 00:02:00 to 00:05:00, which is not the expected outcome. For some reason, his Python script skips the first 5 seconds of output, even if I replace the -t flag with -to . I've tried to edit his script, but it does not work unless you explicitly specify the time for both video and audio stream, as well as their respective stream URL.

  


• Embed a Youtube with a MP4 File as poster

  29 août 2021, par adampl

  I want to embed a youtube video with a 10 second silent looping MP4 file as the poster.

  


  Currently, I am using the Wordpress video shortcode with my MP4 as the poster source, it works on some browsers but not all. Can anyone help ? I would prefer to find a pure HTML solution separate to the wordpress shortcode as I will need to get this to work on other CMSs.

  


  [video src="https://www.youtube.com/watch?v=[videoID]" poster=<video autoplay="autoplay" loop="loop" muted="muted" playsinline="playsinline">&#xA;  <source src="/wp-content-directory/intro.mp4" type="video/mp4">&#xA;</source></video>]&#xA;

  


  What i have found is to get a looping MP4 work on all browsers, I have to use this tag with the autoplay loop muted and playsinline

  


  <video autoplay="autoplay" loop="loop" muted="muted" playsinline="playsinline">&#xA;<source src="/directory/intro.mp4" type="video/mp4">&#xA;</source></video>&#xA;
