I tried streaming multichannel using server(node-rtsp-web) and client(jsmpeg.min.js).
When I register more than 4 channels, the frame breaks.
Is "jsmpeg.min.js" simply the role of converting base64 values to suit canvas or does it perform decoding?
Or is it transmitting the decoding value from ffmpeg on server(node-rtsp-web) to the client(jsmpeg.min.js) using webSocket?

Stream = require('node-rtsp-stream') stream = new Stream({ name: `STREAM`, streamUrl: RTSP_URL, wsPort: WS_PORT, ffmpegOptions: { '-s': '640x360', '-b:v': '1000k', '-r': 20 } })
I'm not familiar with node-rtsp-web, but it seems to transcode any(?) input video into MPEG1 on the server. So MPEG1 video goes over the wire.
JSMpeg decodes MPEG1 on the client.
