stream.getVideoTracks()[0].enabled should blank off the stream?

[derMani]

Expected behavior

getVideoTracks()[0].enabled = false

should blank off the screen (just sending a black image). Ideal for muting the camera.
Same behavior can be seen with webrtc in chrome

Observed behavior

getVideoTracks()[0].enabled = false

just pauses/freezes the screen. The last video frame can be seen

Steps to reproduce the problem

Create a stream with getUserMedia and attach it to a video element

Set

stream.getVideoTracks()[0].enabled

to false

We would need to clear the texture buffer to be blank instead of last frame.

Im not considering that a bug. I will see what I can do.

Cool and thanks! Hint: In previous versions (< 5.x) the video was black when enabled was set to false.

Maybe you can somehow reuse the code there.

@derMani this part of the implementation did not change, WebRTC.framework did however, so that might be where the issue lies. Thx for input.

I had the same problem, the stream stuck in the last frame

Related #427

[oscarvadillog]

I have tested #427 and the video is paused when getVideoTracks()[0].enabled = false

[hthetiot]

I may have an idea, I may disable rendering all together when enabled false.
