Please tell me about the flv stream method.

[pikesaury]

I was using flv.js but am trying to change to mpegts.js.
I am trying to receive OBS data over a local IP.
In flv.js.

/flv?port=1935&app=live&stream=ch1

I can stream flv with this.
but in mpegts.js it only shows still images.
I am using nginx rtmp to flv module,Is there anything I should fix?

<script src="static/mpegts.js"></script>
<video id="videoElement"></video>
<script>
if (mpegts.getFeatureList().mseLivePlayback) {
var videoElement = document.getElementById('videoElement');
var player = mpegts.createPlayer({
type: 'flv', // could also be mpegts, m2ts, flv
isLive: true,
url: '/flv?port=1935&app=live&stream=ch1'
});
player.attachMediaElement(videoElement);
player.load();
player.play();
}
</script>
