• How to limit youtube-dl on video length when downloading a youtube stream

  3 août 2016, par user3682869

  Im trying to write a small script that records a live stream from youtube.
  when using youtube-dl.download function it just keeps on downloading until the stream ends, but i want to stop downloading after 20min or so.
  the problem is when i try killing it after a while the output is corrupted (im using mp4 format), and i tried fixing it with ffmpeg but a "moov atom not found" error occurs.

  How can i make youtube-dl (or any other tool) record a fixed length of a live stream ?

  Here’s a portion of the code :

  class recordingThread (threading.Thread):
  
  def __init__(self, threadID, output_location, name, yt_stream, start_time):
  
      threading.Thread.__init__(self)
  
  
  
      self.threadID = threadID
  
      self.output = os.path.abspath(output_location)
  
      self.name = name
  
      self.start_time = start_time
  
  
  
      self.ydl_opts = {'quiet': True,
  
                       'format': 'mp4',
  
                       'outtmpl': name+ '%(ext)s',
  
                       'sleep_interval': 2
  
                       }
  
      self.yt_stream = yt_stream.strip('\'"')
  
  
  
  def run(self):
  
      print "Starting %s Thread Recorder - %s" % (self.name, self.start_time)
  
  
  
      with youtube_dl.YoutubeDL(self.ydl_opts) as ydl:
  
          self.download_prc = ydl.download([self.yt_stream])

  Thanks.

• Best way to convert webm to mp4 using ffmpeg

  23 mai 2019, par Tregos

  Having problems converting webm to mp4 using ffmpeg.

  I have tried moving ffmpeg to the src folder and using exec($cmd,$out,$ret) on a php code i wrote. when i run the same cmd line on windows using cmd it converts the file from webm to mp4.
  $cmd =’-i’.$videoWebm.’-qscale 0’.$videoMp4 ;
  found some info here but it is still not helping
  FFMPEG convert webm to mp4 not working

  code

   newfile = path to ffmpeg.exe ,which is the same path as $videoWebm
  
      $videoWebm =path to webm file 
  
      $videoMp4= path to save mp4 file ,which is the same path as $videoWebm
  
      $cmd ='-i'.$videoWebm.'-qscale 0'.$videoMp4;
  
  
  
      exec($newfile.$cmd,$out,$ret);
  
      if ($ret){
  
        $statusMsg= "There was a problem!\n";
  
        print_r($cmd.'\n');
  
        print_r($out);
  
        } else {
  
            $statusMsg= "Ffmpeg successfully converted files into mp4 from WebM 
  
           container!\n";
  
        }

  the webm file records and the video file gets uploaded to $videoWebm. I’m also inserting some data to the database to save file information. but the converting web to mp4 never gets done Please help if you can thanks.
