Getting notified when switching camera

[LinusU]

I'm trying to have my local video stream mirrored when using the front-facing camera, but not mirrored when using the back camera.

My current code looks something like this:

_localStream.getVideoTracks()[0].switchCamera();
_renderer.mirror = !_renderer.mirror;

The problem is that switchCamera takes ~1s, but setting the mirror property is instant. It thus creates a bit of an awkward UI experience...

Is it possible to get a callback when the camera is actually switched, so that I can time setting mirror at the exact same time?

This will be very useful since I'm searching for the same feature

Well, this one is pretty easy to implement
Okay, let me just do it ;)

Please somebody test it

@rostopira just tested it and works great! Thanks for the quick implementation!

Sometimes I'm seeing one or two frames that's not mirrored after switching, but much better than before...

Thanks! 🚀

How are getting the local renderer to mirror? I don't see this functionality anymore.

Ended up just flipping it in the UI code

Transform(
                      alignment: Alignment.center,
                      transform:
                          _mirrorLocalRenderer ? Matrix4.rotationY(3.14159) : Matrix4.identity(),
                      child: ClipRRect(
                        borderRadius: const BorderRadius.all(Radius.circular(8)),
                        child: RTCVideoView(
                          _localRenderer!,
                          objectFit: RTCVideoViewObjectFit.RTCVideoViewObjectFitCover,
                          filterQuality: FilterQuality.medium,
                        ),
                      ),
                    )

RTCVideoView(_localRenderer, mirror: true);
