Description
Package version
2.4.0-exp.5
Environment
* OS: Windows 11
* Unity version: Unity 2020.3
Steps To Reproduce
The following code displays the video on the screen but sometimes crashes for no reason
peer.OnTrack = e => {
if (e.Track.Kind == TrackKind.Video)
{
(e.Track as VideoStreamTrack).OnVideoReceived += tex =>
{
rawImage.texture = tex;
};
}
};
Current Behavior
The thread tried to read from or write to a virtual address for which it does not have the appropriate access.
