Missing properties of Media Tracks

[ahmetceylan]

Which platform(s) does your issue occur on?

• iOS/Android/Both

Please, tell us how to recreate the issue in as much detail as possible.

Describe the steps to reproduce it.

Can you please implement following properties of media track objects;

• video tracks;
  ** aspectRatio
  ** facingMode
  ** frameRate
  ** height
  ** width

• audio tracks;
  ** volume

and also, it would be good to have an event that is firing when the aspect ratio is changed

video tracks

• aspectRatio
• facingMode
• frameRate
• height
• width

audio tracks

• volume

@triniwiz so in alpha22, what is the best way to get access to the aspect ratio of the local video stream? For example, in the main page of the ng-demo-firestore I am showing a preview of the local video stream, where I set the width to screen.mainScreen.widthDIPs/4. However, I want to set the height to something that respects the aspectRatio, so how do I get the relative height?

In the context of these lines, I tried to do the following: console.dir(mediaStream.videoTracks[0].settings);

On Android I got the following output:

JS: ==== object dump start ====
JS: _mediaTrackSettings: co.fitcom.fancywebrtc.FancyRTCMediaTrackSettings@c70e655
JS: width: "640"
JS: height: "480"
JS: frameRate: "30000"
JS: aspectRatio: "1"
JS: facingMode: "user"
JS: ==== object dump end ====

Some questions:

• I assume the frameRate property here is 30fps (why does it report 30000?)
• the aspectRatio property is relative to what?
• the width and the height here are from what?(https://github.com/triniwiz/nativescript-webrtc/blob/alpha22/demo-ng-firestore/src/app/webrtc/webrtc.provider.ts#L186-L187) don't seem to influence what the settings show. Also in portrait mode, I would expect the width to be smaller than the height.

Thanks!

1. Milliseconds value (we could try returning seconds)
2. This should be showing the correct ratio because (noticed I commented this
3. Might be related to no.2 but those are the default values of non was specified when get usermedia was called also it would check if the device does support that size or get the closest supported size
