Video VideoPlayer.StepForward and missing frameReady Events

Hi,

I am using the Unity VideoPlayer to step through a paused video file frame by frame.
To do this, I pause the videoPlayer and register a frameReady event
In my frameReady event handler I use StepForward to move to the next frame.

Everything works great on my video files until I reach frame 28, When I call StepForward I see my video display frame 29 but I never get the frameReady event. I have multiple test MP4 files that this happens on.

When it sticks on frame 28, if I call StepForward an extra time, then it completes the rest of the video with no issues.

Thanks for any light anyone might be able to shed on this, it's a bit frustrating, I'd rather not have to manually code a "If frame 28 then call step forward twice", eek.

Unity 2019.2.4f1, running on MacOS

For what it's worth the code snippet is:

Code (CSharp):

1.     void OnFrameReady(VideoPlayer source, long frameIndex) {
2.  
3.         Debug.Log("FrameReady: " + frameIndex);
4.         // poseEstimation.AddPose(source.texture as RenderTexture, frameIndex);
5.         source.StepForward();
6.     }
7.  

and

Code (CSharp):

1.     void Start()
2.     {
3.         videoPlayer.Pause();
4.         videoPlayer.sendFrameReadyEvents = true;
5.         videoPlayer.frameReady += OnFrameReady;
6.     }
7.  

 

I have submitted the bug with a minimal reproduction project but have not been issued with an issue ID, is there anywhere I can check whether it submitted correctly?

 

Ah, sorry, just delayed, here is the issue ID: 1187256
