• youtube-dl doesn't see ffmpeg in the executable

  30 novembre 2019, par Михаил Муратов

  I am writing a program to download music and videos via youtube-dl in python. Next, I pack the script into an executable file via pyinstaller.

  The problem is that youtube-dl (in the executable) doesn’t see ffmpeg and ffprobe, even though I add them to the spec file.

  As far as I know youtube-dl has the ffmpeg_location parameter, but that’s only in the console version. Maybe it is also for python ? But I didn’t find any information about it.

  How do I solve the problem ?

  command to create executable :

  pyinstaller --upx-dir=c:\users\exe-builder c:\users\exe-builder\youtubedownloader\main.spec

  .spec file :

  # -*- mode: python -*

• Cannot display ffprobe information from youtube properly

  31 janvier, par Krishnaap

  I am trying to grab information from youtube streams using ffprobe and python. I could display offline video information properly on python, cannot do the same from youtube live streams.

  


  
os.system("ffprobe -hide_banner -stats -v quiet -pretty -show_entries format=size,duration:stream=filename,index,codec_type,codec_name,profile,bit_rate,width,height -of compact -i https://www.youtube.com/watch?v=QzsfLSP6hkI")


  


  showing an error

  


  


  Argument 'https://www.youtube.com/watch?v=QzsfLSP6hkI' ; provided as input filename, but 'quiet' was already specified.

  


  


• Too little fps on stream YouTube

  12 novembre 2017, par Stretch

  In last Friday I bought old computer to stream video and sound on YouTube but I have little FPS on output.
  Input there is a camera(protocol RTSP) 1920x1080 in 15FPS and sound PCM. I want to stream on YouTube on full hd so I don’t use libx264 but on copy.

  ffmpeg -rtsp_transport tcp -i "rtsp://user:pass@ip:554/cam/realmonitor?channel=1&subtype=0" -tune zerolatency -vcodec libx264 -pix_fmt yuv420p -c:v copy -r 15 -bf 2 -g 30 -c:a aac -ar 44100 -b:a 128k -ac 1 -preset ultrafast -bufsize 2M -movflags +faststart -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/xxxxxxxx -threads 2

  My computer :
  Intel Core 2 Duo e7500
  4GB RAM
  Windows 7
  Computer use procesor in 1-5%.
  Why stream have only 7FPS sometimes 10-13 ?
