• pipe youtube-dl to ffmpeg within a script

  28 février 2016, par user556068

  This is an expansion to an earlier question I asked which you can find here. I have been piping youtube-dl into a script via youtube-dl -iga /path/to/myFile.txt | myscript.sh which reads a text file of urls and extracts another set of urls to the actual video content being downloaded. Everything works great but there is much room for improvement.

  Instead of piping youtube-dl into the script I would like to include the youtube-dl command within the script itself. Here is the full script I have up to this point.

  #!/bin/bash  
  
  
  
  inArgs='-i'                 
  
  outArgs='-c copy -y'        
  
  dir="$HOME/Movies/fftest/"
  
  outFile="fftest_${count}"       
  
  ext='.mp4'        
  
  
  
  #### not sure about following 2 lines
  
  
  
  youtube-dl -iga /path/to/myFile.txt > /path/to/myFile2.txt
  
  exec 0to/myFile2.txt
  
  
  
  count=0
  
  if [ ! -d "${dir}" ]; 
  
  then
  
  mkdir -p "${dir}"
  
  fi      
  
  cd || "${HOME}"
  
  
  
  while read lineIn
  
  do
  
  {
  
  (( count ++ ))
  
  echo ffmpeg $inArgs $lineIn $outArgs "$dir$outFile$count$ext" &
  
  sleep 1
  
  }  
  
  done  

  After playing around with it a little I added the following lines. Code has been edited to reflect these changes.

  youtube-dl -iga /path/to/myFile.txt > /path/to/myFile2.txt
  
  exec 0to/myFile2.txt 

  This does work but it’s also throwing up some new error from ffmpeg that I haven’t yet encountered until now. I test by placing echo before the ffmpeg command. Everything looks fine doing that so I’m not really sure what the issue is at this point.

  So there are a couple things i would like to accomplish that I haven’t been able to figure out.

  • Have I properly redirected the input and do I need to do anything later in the script to put things back as they were before the script was called or will that occur naturally on its own when exiting the script ?

  • As it currently is, the script will overwrite any files previously created every time it is called. This is fine for testing purposes but not ideal beyond that. What I am looking for is a way to start writing the next file in the number sequence based on the last file in the directory. So if one time it creates 8 files named fftest_1.mpr - fftest_8.mp4 the second time when it is called to create 14 new files, it will know to start writing a file labeled fftest_9.mp4 - fftest_22.mp4. This is however beyond my abilities at the moment. Is there a way to do this ?

  • Another issue I’ve had is when trying kill the script as it runs in the background. Ctrl C doesn’t have any effect as far as I can tell. Is there an alternative kill command or key press I can use to ensure an immediate exit if necessary. Or a way to assign such within the script itself ?

  • Also any critiques, suggestions, alternatives or additions to any part of this script are very much welcomed and appreciated. This is all very new for me and I’m trying to learn more everyday. If any part of what I said didn’t make sense I will be happy to clarify.

  2 novembre 2024, par Darter

  i would like to re-stream an rtsp stream of a wifi camera to youtube
the stream is allready a H.264 codec.

  


  The camera does not have any audio, but youtube needs audio to accept the stream, thats why i faked and audio stream.
I tried this

  


  ffmpeg -re -rtsp_transport tcp -i rtsp://192.168.1.140/live -f lavfi -i anullsrc -f rawvideo rtmp://a.rtmp.youtube.com/live2/<stream key="key">&#xA;</stream>

  


  but it fails

  


  av_interleaved_write_frame(): Broken pipeB time=00:00:00.20 bitrate=884736.0kbits/s speed=0.0156x    
Error writing trailer of rtmp://a.rtmp.youtube.com/live2/dgyh-qzba-t13k-6qtf-6rgq: Broken pipe


  


  i would like to not change the codec to not put any stress on the machine

  


• How do I auto-start streamlink to capture YouTube live stream once the capture stopes in 6 hours with session expiration ? [closed]

  13 janvier 2020, par Anoma

  I’m using Streamlink to capture a YouTube live stream. But as everyone knows, the capture ends in 6hrs with YouTube session expiration. As I’m new in scripting, could anyone please help me to overcome this issue ?

  I’m looking for a script that can automatically start a new session with the same YouTube live stream after a given time or once the scrip detects the error : "Error when reading from stream : Read timeout, exiting" in 6 hours.

  Thank you in advance.
