NotchLC transparent videos have red-blue channel swapped randomly #1228

Closed marcseibert closed 1 year ago

marcseibert commented 2 years ago

Problem description:

Sometimes our videos (NotchLC codec with transparency) are tinted blue. The blue tint is visible in the MediaPlayer Component aswell as the displayed Texture on the screen.

We can't find any real pattern to when the texture turns blue. The MediaPlayer doesn't throw any Exception Events.

Device (which devices are you having the issue with - model, OS version number):

Desktop, Windows 10.1

Media (tell us about your videos - number of videos, resolution, codec, frame-rate, example URLs):

In the photo you can see 3 NotchLC encoded videos with transparency displayed using a DisplayuGUI component. The screenshot has been blurred and cut to protect the data of our customer.

The first two videos are ok but the third video is tinted blue. Problem Example Screenshot

There are approximately 9 Videos Loaded in Full HD resolution encoded in NotchLC. The Probelm also occurs when loading a single video only.

Hi @marcseibert,

  1. Is it the same video that you are having difficulty with or is it random?
  2. Are all of your drivers up to date?
  3. How do they all play in a different mediaplayer?
  4. Could you give a bit more detail about the videos files please? File container etc
  5. What are your CPU and GPU usage like when playing these?

I think we've identified the issue. We will test more on Monday to confirm.

@AndrewRH Thanks for looking into the issue so quickly! @Chris-RH for completeness reasons:

1. Is it the same video that you are having difficulty with or is it random? No, we have multiple videos (all encoded in NotchLC). Sometimes the videos load correctly and sometimes they don't.

2. Are all of your drivers up to date? Yes.

3. How do they all play in a different mediaplayer? Each DisplayuGUI has a separate MediaPlayer each loading a different video file.

4. Could you give a bit more detail about the videos files please? File container etc Length: 10s Frame size: 1920 x 1080 (width x height) Data rate: 89674kbps Frame rate: 25 frames/second Size: 106MB

5. What are your CPU and GPU usage like when playing these? When running in editor mode the CPU usage averages around 40% utilization and GPU around 35%.

Thanks, the fix for this will be in the next release (2.5.5 likely) which may be out later this week.

Thanks,
