WebRTC: Long time for the first picture when RTC2RTMP. Push RTC and pull RTMP, VLC takes a long time for the first screen, around 2 minutes.

Please describe your issue here. I am running Docker with WebRTC push and VLC pull. It takes a long time to load, possibly up to 2 minutes, before it appears. Is this normal?

WebRTC was not originally designed for live streaming, so there will be many issues if you use WebRTC for live streaming or convert it into a live streaming protocol.

However, there should be room for optimization.
