webRTC with external video stream instead of local camera

[Tiến Nguyễn]

Hi All,

What would it take to use easyRTC to relay a RTSP video stream to another client instead of using the local camera?

Thanks,

[Nicholas Hall]

Not sure if you can do this natively in EasyRTC but you could setup a virtual video source on a system using v4l2loopback that is fed from your RTSP source.

There are some other ideas listed on this stackoverflow too.  Good luck.

From what I've read, Chrome supports forwarding remote media streams (at least the video component, not sure about the audio).  In theory, you should be able to do with using the easyrtc functions buildLocalMediaStream and getRemoteStream. I haven't tried it myself yet.

buildLocalMediaStream(streamName, audioTracks, videoTracks) → {void}

This function builds a new named local media stream from a set of existing audio and video tracks from other media streams.

Parameters:

Name	Type	Description
streamName	String	is the name of the new media stream.
audioTracks	Array	is an array of MediaStreamTracks
videoTracks	Array	is an array of MediaStreamTracks

Returns:

Type

void

Example

   easyrtc.buildLocalMediaStream("myComposedStream",
            easyrtc.getLocalStream("camera1").getVideoTracks(),
            easyrtc.getLocalStream("camera2").getAudioTracks());

the relaying of audio stream is not implemented yet. They have to change all the audio plumbing in webrtc and chromium for it to work (the mixer need to move from libwebrtc to chromium, so individual audio track can be manipulated. Right now the audio is mixed right away, and it s then impossible to get a separate track to relay it).
