Any other Media Player component configuration required to reproduce the issue.
Multiple MediaPlayer and DisplayUGUI components are created dynamically at runtime.
Each player has its own DisplayUGUI component. The components are destroyed when the video view is disposed.
The issue occurs in the macOS Unity Editor.
Which output component(s) are you using?
Display uGUI
Any other component configuration required to reproduce the issue.
No special configuration is required.
The issue appears to be related to the [ExecuteInEditMode] behavior added to DisplayUGUI. It occurs during a uGUI Canvas rebuild while the MediaPlayer is being initialized or disposed.
The issue
After upgrading AVPro Video Ultra from 3.3.3 to 3.4.2, we occasionally see the following exception when running the project in the macOS Unity Editor:
NullReferenceException: Object reference not set to an instance of an object
RenderHeads.Media.AVProVideo.DisplayUGUI.GetDrawingDimensions
(UnityEngine.ScaleMode scaleMode, UnityEngine.Rect& uvRect)
(at Assets/AVProVideo/Extensions/UnityUI/Runtime/DisplayUGUI.cs:620)
RenderHeads.Media.AVProVideo.DisplayUGUI._OnFillVBO
(System.Collections.Generic.List`1[T] vbo)
(at Assets/AVProVideo/Extensions/UnityUI/Runtime/DisplayUGUI.cs:547)
RenderHeads.Media.AVProVideo.DisplayUGUI.OnPopulateMesh
(UnityEngine.UI.VertexHelper vh)
(at Assets/AVProVideo/Extensions/UnityUI/Runtime/DisplayUGUI.cs:533)
We suspect that the following access to MediaPlayer.Info in GetDrawingDimensions() may be related:
_mediaPlayer.Info.GetTextureTransform()
HasValidTexture() checks MediaPlayer and TextureProducer, but it does not appear to check whether MediaPlayer.Info is available. It may therefore be possible for this code to run while Info is null, for example during player initialization or disposal.
Adding a null check for MediaPlayer.Info appears to prevent the exception in our project. Could you please confirm whether this is a known issue?
