Integrating WebRTC in the existing IP camera solution over Android/Stagefright framework

[ankit singhal]

Hello All,

We have an IP camera solution based on Android using the stagefright framework. We are using Live555 for RTSP streaming. 

We are not using gstreamer in our solution. 

Our IP camera solution supports H264 hardware encoding. I would like to know how can i integrate WebRTC into our solution with H264 video. 

Is H264 well supported or transcoding to VP8 is mandatory?

Can we give the encoded H264 video to getUserMedia() as a stream input? 

We are using Go server. Can somebody suggest what are the WebRTC native components to be used for development?

regards

You want to launch webrtc server on IP camera?

Or you want to create a mediator that will take video from camera and send it over webrtc?

Hi Max,

I want to launch the webrtc server on IP camera. There could be multiple clients accessing the camera AV over webRTC.

We have H264 encoded data. Can it directly be used as input to webRTC or does it always take input as raw AV and then encodes it?

We can not port any browser like chrome which supports webRTC. We only want to port the webRTC native for our use case.

Also, There is a getUserMedia API used in webRTC for media. I believe it is supported in the browser and not really part of webRTC and it is coupled with webcam and microphone of the device. How can i use webRTC and pass on the AV captured through our IP cam and also encoded using H264 encoder

I would really appreciate if i can get an early response.

It is an interesting task and we are also working on it.

You need to dig inside webrtc protocols and implement all this as if your server is a peer browser.

But getUserMedia is just a javascript function. It is not related to your server.

Hello Ankit

I just saw your posts here, were you able to implement this? We are also looking at the same solution and could not reach anywhere, if you have then please help.

Hi Gautam,

No we could not get any help. Now, we are looking at webrtc native in android chromium. It is mentioned on webrtc.org and trying to follow the Apprtc example.

This activity is kind of stalled for now.

If you find something, please let me know as well.

Hi all,

Was anyone able to launch webRTC on an ip camera? Any tips for someone attempting to use webRTC for video surveillance? Any advice would be greatly appreciated.

Thanks,

James

You may want to have a look at Janus (full disclosure, I'm the author), in particular at the Streaming plugin which provides RTSP-to-WebRTC functionality, as I know of many people who've used it for similar projects.

Is there any reason why Janus would be the better choice for this use-case over Kurento?

Hi Lorenzo...

Is there an Android port of Janus in the works?  I am also interested an RTSP-to-WebRTC implementation but I need it to work on the equivalent of an Android tablet (Allwinner A64, 2GB ram, 4GB flash, Marshmallow).  That is, I have the equivalent of an Android tablet connected via ethernet to a common security camera module.  The security camera is pumping out h264 via RTSP which the A64 can capture.

I see in the Meetecho-janus discussion group there was some discussion of this a few years ago.  Did anything come of it?  Honestly, I am less interested in the Java native wrapper than I am in getting some WebRTC pipeline that doesn't mess with the frames/packets as they are passed out to the client.  I currently have libjingle doing this but I have had to hack up some of the link optimization stuff (frame-dropper, bit-rate-estimator) to make it work.  That makes maintenance a problem and I would prefer to avoid that.

Yes.

[James Kaye]

Could you please elaborate on this?

[Lorenzo Miniero]

Hi Tyler,

personally we're not planning any work in that direction. Android is Linux based so it MAY be installable already (you can easily install it on arm-based processors like R.Pis for instance, which is what many people do) but that's just speculation. If possible, that would only leave you with how to hook it to the Java side of things, but no idea honestly...
