  • Sending video stream from NodeJS to python in real time [closed]

    17 juin 2021, par Tristan Delort

    I'm using a NodeJS server to catch a video stream through a WebRTC PeerConnection and I need to send it to a python script.

    


    I use NodeJS mainly because it's easy to use WebRTC in it and the package 'wrtc' supports RTCVideoSink and python's aiortc doesn't.

    


    I was thinking of using a named pipe with ffmpeg to stream the video stream but 3 questions arose :

    


      


    • Should I use python instead of NodeJS and completely avoid the stream through a named pipe part ? (This means there is a way to extract individual frames from a MediaStreamTrack in python)

      


      • 


    • If I stick with the "NodeJS - Python" approach, how do I send the stream from one script to the other ? Named pipe ? Unix domain sockets ? And with FFMpeg ?

      


      • 


    • Finally, for performance purpose I think that sending a stream and not each individual frames is better and simpler but is this true ?

      


      • 


    


    Thanks all !
