Hi, i’m using webrtc one way to mediasoup, then plaintransport over to ffmpeg. How can i tell webrtc client to send a keyframe every time i set up a new ffmpeg stream, so ffmpeg doesn’t have to wait 1-2 minutes for a keyframe?

I can’t find any api call for it? I assume i need to craft a “FIR” packet, but google doesn’t help me much 🙂
