Describe the issue
A clear and concise description of what the issue is.

Your Setup (please complete the following information):

• Unity version: 2022.2.0b11
• AVPro Video version: 2.8.4 ultra
• Operating system version: Windows 10
• Device model: AMD Ryzen 5 3400G
• Video specs (resolution, frame-rate, codec, file size): 960x540, 60fps, mp4, 13.1MB

To Reproduce

1. Use a VideoRender object in the normal way to play the video as part of a Unity project.
2. Mostly the video plays correctly and looks fine.
3. Every few seconds, a frame of the video contains only fully transparent pixels, causing flickering when the video contrasts with the graphical layer behind it (see screenshot below).

Note
This problem was not seen when using v2.7.3 with the same video and project.

Is it possible to send over the video?

[domcamus]

Certainly. Will send to: unitysupport@renderheads.com

[Ste-RH]

Are you using DX11 or DX12?

What GPU?

[domcamus]

GPU: NVIDIA GeForce GTX 1660 Super

I think I'm using DX11, but not 100% sure. How can I check?

[Ste-RH]

It will say in the title bar of the Unity Editor.

Have you tried reproducing the issue on another PC with a different GPU?

[domcamus]

Thanks. Confirmed: it is DX11.

The bug was reported by a user, so definitely happens on another PC and very likely also a different GPU (because most of our users are on laptops and I use a desktop).

Hi @domcamus,

Is this happening with a particular video playback API? (DirectShow, Media Foundation, WinRT)

Also, is it possible every few seconds happens to be when the video loops? (Just trying to narrow down possibilities)

Cheers,

[domcamus]

@RichRH - It's happening with Media Foundation. (Haven't tried anything else.)

[RichRH]

Merging this into #1700 as the same issue.

This should be fixed in AVPro Video version 3.0.0. The trial version is available here for testing. Please let us know if the issue is not fixed in this version.
