Pushing RTMP from DJI Go 4 App (Android) to RTSPSS. RTMP to RTSP. VLC and FFplay work, but other ffmpeg based clients we have do not.

Standard config, no special settings.

The client (RtspClientSharp) is trying to setup the audio track before the video track - i don't know why it is doing this, but it's highly non-standard and depends on the client, not on the server.
