Last frames of video are repeated when played using Video Player Component

-

Jan 06, 2020

How to reproduce:
1. Open attached project "Case_1209623"
2. Load SampleScene
3. Press Play

Expected result: video is played without any repeated frames
Actual result: the last couple of frames of the video are repeated a couple of times

Reproducible with: 2019.3.0f4, 2020.1.0a17, 2020.1.0a18
Not reproducible with: 2018.4.15f1, 2019.3.0f3, 2020.1.0a1, 2020.1.0a16

Resolution Note (fix version 2020.1):

Fixed in 2020.1.0a24
Missing synchronization logic in the video decoding setup was causing the last few frames to use stale textures on nVidia hardware.
Resolution Note (fix version 2019.3):

Just experienced this in the latest version 2019.3.6f1 so it does not seem to be fixed completely.
It looks like previous frames are being repeated as described

It only happens in Fullscreen mode with VSync on. Borderless and/or VSync off works without issues.

-The videoclip asset is not encoded through Unity.
-The video is a MP4 file (x264, 3840x2160, 60FPS constant(matches refresh rate of monitor), ~50Mb/s)

Yes, an update on this would be much appreciated. It never happened prior to 2109.3.

Can anyone from Unity advise when we might expect a fix for this bug? Regards, Simon
