One Way Streaming

[Kamran95]

Hello Everyone! i am using peerjs for screensharing purpose only which is one way streaming. Is there any way to achieve this, that one user sends his desktop capture as a stream whereas other user sends no stream. Looking forward for your answer

I'm not sure you can send without stream but you can create and empty stream.

function createEmptyVideoTrack({ width, height }) {
    const canvas = Object.assign(document.createElement('canvas'), { width, height });
    canvas.getContext('2d').fillRect(0, 0, width, height);

    const stream = canvas.captureStream();
    const track = stream.getVideoTracks()[0];

    return Object.assign(track, { enabled: false });
};

and create the stream

 const videoTrack = createEmptyVideoTrack({ width: 500, height: 500 })
 const mediaStream = new MediaStream([ videoTrack]);
call.answer(mediaStream)

I'm pretty certain this is covered in the docs if I have understood you correctly.

All you would need to do is answer the call on the receiving end without passing any argument back to the caller;

ex:

call.answer()

From the docs;

When answering a call, the MediaStream is optional and if none is provided then a one-way call is established.
