• python modules ffmpeg and ffprobe are installed but youtube-dl not able to find

  12 avril 2022, par Akshay Hiremath

  I'm using python 3.8 on MacOS Big Sur

  


  I installed python module package for youtube-dl with

  


  pip3 install -upgrade youtube-dl


  


  I wanted to do post processing on the content downloaded so I installed python packages ffprobe and ffmpeg.

  


  pip3 install ffprobe
Collecting ffprobe

  pip3 list 
Package    Version   
---------- ----------
ffmpeg     1.4       
ffprobe    0.5           
youtube-dl 2021.12.17 


  


  Still it is complaining can't find ffprobe and ffmpeg :

  


  youtube_dl.utils.DownloadError: ERROR: ffprobe/avprobe and ffmpeg/avconv not found. Please install one.


  


  I see both packages in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/

  


  Trying to figure out what am I doing wrong. Many other answers to similar questions on SFO are suggesting installing these packages in the OS using brew etc. but in my case "I want to do everything through python". So shouldn't just installing python modules be enough ?

  


• Use FFMPEG to restream RTMP source to YouTube - no video stream in output

  5 février 2018, par Mike Miller

  I am attempting to grab the .m3u8 file from an nginx-rtmp server and pass it along to YouTube rtmp. I believe this to be possible (for example here : https://stackoverflow.com/a/11978820/1552594 although this is on the same host). The command I am using is :

  ffmpeg -analyzeduration 0 -i \
  
  http://source.rtmp.server/hls/stream.m3u8 -pix_fmt yuv420p \ 
  
  -f flv rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx

  However the output contains only audio and YouTube doesn’t like it. The command produces following :

  

  As you can see no Video stream in output metadata, stream mapping shows only audio and the trace shows 0kb of Video for 651kb of Audio

  Any help much appreciated

  MORE INFO

  Improved version of the command lifted from this article :

  https://judge2020.com/restreaming-a-m3u8-hls-stream-to-youtube-using-ffmpeg/

  "Restreaming a m3u8 HLS stream to Youtube using FFMPEG" AKA exactly what I am trying to do.

  The command I am sending is now :

  ffmpeg -re -i "http://source.rtmp.server/hls/stream.m3u8" \ 
  
  -strict -2 -c:v copy -c:a aac -ar 44100 -ab 128k -ac 2 -flags \ 
  
  +global_header -bsf:a aac_adtstoasc -bufsize 3000k -f flv \ 
  
  "rtmp://a.rtmp.youtube.com/live2/xxx-xxxx-xxxx-xxxx"

  I got pretty much exactly the same response except with the Audio being read and output using aac codec.

  

  MORE MORE INFO

  I have found that adding a mapping can force the video stream into the output :

  ffmpeg -re -i "http://source.rtmp.server/hls/stream.m3u8" \
  
  -strict -2 -c:v copy -c:a -map 0:0 -map 0:1 -ar 44100 -ab 128k -ac 2 \ 
  
  -flags +global_header -bsf:a aac_adtstoasc -bufsize 1000k \
  
  -f flv "rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx"

  This throws up the error that has presumably been resulting in the video stream being silently dropped :
