timecodestamper after webrtcbin -> decodebin failed ?

[Michael]

also already added "framerate" as MediaConstraints but still

video/x-raw, format=(string)I420, width=(int)640, height=(int)480,
interlace-mode=(string)progressive, multiview-mode=(string)mono,
multiview-flags=(GstVideoMultiviewFlagsSet)0:ffffffff:/right-view-first/left-flipped/left-flopped/right-flipped/right-flopped/half-aspect/mixed-mono,
pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)jpeg,
colorimetry=(string)bt601, framerate=(fraction)0/1


// navigator.mediaDevices.getSupportedConstraints()
const stream = await navigator.mediaDevices.getUserMedia({
"audio": true,
// https://developer.mozilla.org/en-US/docs/Web/API/MediaTrackConstraints
"video": {
frameRate: {
exact: 25,
ideal: 25
}
}
});
console.debug("md::getUserMedia sucess",stream);
//Play it
addVideoForStream(stream,true);
// we add stream later
pc.addStream(stream);

I am lost in this case, now.
