  • How to live stream generative video via ffmpeg

    24 septembre 2021, par Ken

    I would like to live-stream generative audio and generative video on the web. It would be an "autonomous" setup, without anyone in front of a camera to address the audience, etc. But it needs to be "live" because it will be interactive (the audience can change parameters that will impact the stream), so it can't all come from a pre-generated file.

    


    Generative audio would come from Reaper, be sent to a virtual audio device and grabbed by ffmpeg, which would then send it to a live streaming platform (say, Youtube).

    


    I think I understand the audio part and got it mostly working.

    


    But what about the video part ? Most examples only mention either a video file or the output of a webcam.

    


    But how does one send the direct output of a program that generates video, such as Processing for example ? Can it be done with piping ? Or should one use a virtual video device ?

    


    Ideally this should work on an Raspberry-Pi but any pointer would be welcome.

    


    This question is related but it's quite old, what would be the best setup for this ?
