Video loaded from Steaming Assets fails to play on start/ready on iOS

[Wayne-nulitics]

When doing a new build on iOS and not using a built in splash screen the app opens, loads the Video but does not play the video.

• Unity version: 2022.3.4f1
• AVPro Video version (number and edition (trial/core/ultra/enterprise)): Ultra 5.1.7
• Operating system version: iOS 16
• Device model: iPhone 12 Pro
• Video specs (resolution, frame-rate, codec, file size): 1024x1024, H264, 2Mb

To Reproduce

1. Set spalsh scene to none
2. Load video from Streaming Assets folder and Render to RawImage via Render to Texture
3. Build and test
4. See error: Unbalanced calls to begin/end appearance transitions for <UnityDefaultViewController: 0x101306f60>.

Debug.Log(eventType);
switch (eventType)
{
case MediaPlayerEvent.EventType.ReadyToPlay:
mediaPlayer.Control.Play();

Reproduced using Unity 2022.3.2f1, AVPro Video 2.8.2, iPhone 13 Pro, iOS 16.5.1
Not reproduced using iPhone X, iOS 14.8.1.

Will get a fix into the next release for this.

The Unity error is nothing to do with AVPro Video.

This issue has been fixed and will make it into the next release, version 2.8.3

AVPro version 2.8.3 has been released. Please let us know if this has not fixed your issue.
