Local video is sometimes empty

[vria]

Hi !

Rarely I get a strange bug that seems to be completely random. In essence, the video of a self camera is empty:

To reproduce a bug one should simply start a call.

Here are some details:

• this happens once in 30-40 tests,
• a camera lights up,
• a distant peer receives a video form the camera,
• localVideo VideoView appears and sized correctly (a rectangle that is appropriately sized)
• I test mostly on Ubuntu 20 but I've seen this problem on Windows also

Have you ever encountered this bug?

Hey,
that should be a JavaFX related bug. There is something wrong with the demo view implementation. I guess the frame arrives in the wrong thread. I will correct that.

Great! It was my suspicion too, I tried to play with threads with no luck.

I figured out the issue. This is because of clipping in VideoViewSkin

Rectangle clip = new Rectangle(newBounds.getWidth(), newBounds.getHeight());

Without it everything works well.
