How to create a H264 room?

1

Hi there,

I see the option Room H264 here https://chotis2.dit.upm.es/
How do I create an H264 room like that?

Thanks.

It’s done in the server side code:

N.API.createRoom(roomName, { mediaConfiguration: 'H264_AND_OPUS' });

For more options check rtp_media_config.js file.

After creating the H264 room, all users still use VP8

I checked it via chrome://chrome-urls/
It’s googCodecName under ssrc report.

How do I know if it works properly?

Thanks.

Yes chrome://webrtc-internals is where you can check. In addition you may activate the log in the client side and check for the SDP:

Thanks, I got it work.

Is it possible to change the codec on clients side?
Here is the scenario:

  • User one connect using Laptop
  • Then user 2 connect using iOS or Android.

I want to detect what user 2 uses, then change the codec to make it works.

Thanks.

Using different codecs in the same room?! Not possible AFAIK.

it works out of the box in p2p mode but I don’t think it’s what you need

So there is no way to let PCs, iOS devices and Android devices to communicate together?

You can wait for the new Safari update which has added supports for VP8: https://github.com/lynckia/licode/issues/915#issuecomment-429266217
