• 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

  


• Adobe connect video : FLV to MP4 (export, convert)

  8 février 2017, par Guillaume Chevalier

  I would like to convert an adobe connect video from .flv in the downloaded zip to .mp4. I have already done the steps explained in this question and answer, however I get .flv files organised like this inside the .zip :

  

  Moreover, I know that ffmpeg can merge video and sound files together as well as concatenating resulting clips directly from the command-line which could be quite useful : https://www.labnol.org/internet/useful-ffmpeg-commands/28490/

  I can’t ask the owner of the video to make it available as an .mp4 from within the adobe connect admin interface. Briefly, I would like to listen to those videos in x2 speed in VLC (just like what I do when listening to random math classes on YouTube - I put ON the x2 speed). The amount of time I would gain to watch adobe connect videos in x2 speed is MASSIVE.

  I think I am not the only one that would like to do this. There are a lot of questions on forums about downloading adobe connect videos, but the .flv format mixed with some .xml is generally a killer when the host does not make the videos properly available in .mp4.

  Dealing with the order of the .flv files is a puzzle. At least, I would not care to flush the chat away and leave some details like that behind, that would help to reconstruct the videos. Any scripts to automate the process would be useful.

• Piwik IRC Meetup on Tuesday

  10 février 2014, par Fabian Becker — Community, Development

  With the release of Piwik 2.0 and the Piwik Marketplace we are focusing on the community aspect of Piwik Development. In order to give users and developers a chance to get involved in Piwik we decided to have IRC meetups every two weeks, where we discuss current and future plans of Piwik development.

  Why should I join ?

  This is the chance for everyone to directly talk to developers and discuss issues and feature ideas. It is also good if you want to get involved in development and pick up smaller features to get to know the code base.

  Next Piwik meetup

  • Date : Tuesday February 11th, 7.30pm UTC
  • Duration : 30min
  • IRC #piwik channel (irc.freenode.net)

  Topics are :

  • 2.1 release (closed tickets)
  • open tickets for Piwik 2.2

  To join the chat, you can use the website : http://webchat.freenode.net/ (or join with your IRC client of choice) – See also what will be the time in your country at 7.30pm UTC. You will find us in the Freenode channel #piwik.
