[FEATURE] Issues with testing RTMP streaming in passthrough mode in Participant mode

[boolw]

Is your feature request related to a problem? Please describe. In Participant mode, in order to test RTMP push streaming in pass-through mode, I set VideoDecoding to false. It works fine when both audio and video are turned on. But if you turn on the audio first (delay for a few minutes before turning on the video to simulate the video development function in the conference), It was found that because there was no video data and videotestsrc.flvmux was not added, it did not work properly. What is the correct approach?

It's using PION under the hood. Best to look there.
