• How to pass real time video to youtube rtmp server for live streaming ?

  31 octobre 2022, par AMRITESH GUPTA

  I am trying to build a project in which a user can post his screen-shared video to youtube live, but I don't know how to pass on that captured stream to youtube using youtube API. Also, I don't want to use any streaming software for this.
I anyone has any idea how to do it, please share it.

  


  P.S. - I am using Nodejs and FFmpeg for video encoding.

  TypeError: must be real number, not NoneType.


  


  It used was to run but I don't remember if I might have updated numpy, ffmpeg, or any thing else that is now causing the error. I have tried the code on python 3.10 and 3.11 and get the same error in both. I was previously running it on python 3.10.

  i need to put the real frame number in the output jpeg image
  i’d try ffmpeg -i inputfile.mp4 -vf "select='eq(pict_type\,I)" -vsync vfr -qscale:v 2 I-frame_num%d.jpeg
