• How to install ffmpeg on Google App Engine ?

  3 mai 2020, par UtkuBulkan

  I intend to install ffmpeg and ffprobe to my Google App Engine flex environment, how can I do this with requirements.txt as a package ?

  



  I am currently using ffmpeg-python yet, this is only a wrapper.

  



  ffmpeg-python==0.2.0
ffprobe-python==1.0.3


  



  Below is the error when I try to use ffmpeg-python wrapper, which is expected as there is no ffmpeg and ffprobe available :

  Can you please suggest a way, so I can use ffprobe on Google App Engine.

  


• avformat/internal : Don't auto-include os_support.h

  31 août 2023, par Andreas Rheinhardt

  avformat/internal : Don't auto-include os_support.h
  It includes various Windows-specific headers when compiling
  
  for Windows and these sometimes cause issues : E.g. winbase.h
  
  defines IGNORE, which clashes with a macro used in the Matroska
  
  muxer (since 884653ee5be03ed38db957c14fad51b300611c8c) and demuxer.
  This header provides fallback defines for various stuff that is
  
  mostly not used directly by (de)muxers at all :
  
  mkdir, rename, rmdir, unlink, access, poll, pollfd, nfds_t,
  
  closesocket, socklen_t, fstat, stat, lseek, SHUT_(RD|WR|RDWR)
  
  and various POLL* constants.
  Ergo fix this issue by not auto-including this header in lots
  
  of places via an inclusion in internal.h and instead include
  
  it everywhere where the above stuff is used (most of these
  
  translation units already included os_support.h).

• Solved - FFMPEG to Youtube Live - YouTube is not currently receiving data [duplicate]

  Since a while, I would like to stream a video to the Youtube Live with FFMPEG. I tried a lot of configurations differents but nothing to the Youtube Dashboard. Every time Youtube feel something :

  Launch in progress

  and finally :

  "YouTube is not currently receiving
  data for this stream. If you believe this is incorrect, ensure you’re
  sending a stream and that it is configured with the correct stream
  key."

  I tried those scripts :

  https://gist.github.com/olasd/9841772

  https://github.com/scivision/PyLivestream

  and a lot ffmpeg command but ... no result.

  Exemple :

  ffmpeg -r 24 -f image2 -s 1920x1080 -i test.mp4 -vcodec libx264 -crf 25 -pix_fmt yuv420p -f flv rtmp://a.rtmp.youtube.com/live2/KEY
  
  
  
  ffmpeg -re -i test.mp4 -c:v libx264 -preset veryfast -maxrate 3000k \ -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 \ -ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/KEY

  If I replace rtmp ://a.rtmp.youtube.com/live2/ by "stream.flv" for exemple, I have the good result in this file.

  Unfortunately the differents topic on this didn’t help me ;
  Any idea please ?

  Thank you !

  PS : I success only with a desktop software : OBS Studio but is not my goal.
