Delay in Obtaining WebRTC Stream

[SMDIndomitable]

Question

Hi, I need some urgent help if possible. I notice some delay in local WebRTC streaming without internet. I already consulted a similar thread raised by another person, but cant seems to figure out. I have ensured that the webrtcICEServers2: [] is empty, is there anything else I need to change?

We're gonna need more information about your "setup". What is the stream source?

Hi, I am streaming from a USB Webcam (UVC) via rtsp to mediamtx, and grabbing the webrtc from mediamtx after. Sorry for the late reply! I was expecting the connection to be faster since is local, but it take around 17 seconds before I can see my webrtc stream

GSTPipelineStream = (
"appsrc ! "
"video/x-raw,format=BGR ! "
"queue ! "
"videoconvert ! "
"video/x-raw,format=BGRx ! "
"nvvidconv ! "
"nvv4l2h264enc bitrate=20000000 ! "
"video/x-h264,level=(string)4,profile=high ! "
"h264parse ! "
"rtspclientsink location=rtsp://localhost:8554/mystream"
)
This is what I am using to send over to mediamtx. For the webrtc is a React + Vite application

Does the stream start up faster when you directly display the restreamed RTSP source through mediamtx? As in, opening rtsp of "mystream" with a program that can display h264 rtsp streams directly (gstreamer itself or whatever)

Just trying to make sure the issue isn't in your encoding pipeline.
