Background filters flip the video upside-down before joining a meeting

[Jim-Bar]

Hi. Recently a fix was made so that it is possible to use background blur / replacement image before joining a meeting session on Android: #504. But now when using those filters before joining a meeting, the video is upside-down.

1. Implement a blur filter
2. Apply it to the video preview, not being in a meeting
3. The blur is applied, but the video is upside down

The same occurs with the background replacement image.

This is actually a follow up on the comments I already posted in the original issue.

Tested on a Samsung Galaxy S20 FE, Android 12 and:

• Amazon Chime SDK 0.17.7
• Amazon Chime SDK Machine learning 0.1.0
• Amazon Chime SDK Media 0.17.8

Thank you for reporting I am able to reproduce the issue. We'll do further investigation and get back to you.

This is due to flipping logic in here. I think internally it comes as flipped which works in this case, but in usual case it might not be working. We'll think of better way to fix this.

All right, thank you for your investigation. We are looking forward to this bug fix.

Hi, do you have news on this?

[hokyungh]

HI sorry I am still working on this issue. I'll let you know when I have solution for this issue.

Hi, this is still an issue for us. Has it been fixed in a new version?

[Jim-Bar]

Hello, sorry to ping repeatedly, but this is still an issue for us. Do you have news on this?

[hokyungh]

Hi sorry for late reply. Unfortunately, I was still caught up with other tasks and didn't have time to work on it. We'll let you know once we work on it, but for short-term mitigation, would it be possible to implement CustomBackgroundProcessor before joining that resembles BackgroundFilterVideoFrameProcessor.kt?

@hokyungh any news on this one? It's still occurring on the latests (0.19.1) release

I tried creating a CustomBackgroundReplacementVideoFrameProcessor, CustomBackgroundFilterVideoFrameProcessor is the same as BackgroundReplacementVideoFrameProcessor, BackgroundFilterVideoFrameProcessor file. In the CustomBackgroundReplacementVideoFrameProcessor file, replace BackgroundFilterVideoFrameProcessor with CustomBackgroundFilterVideoFrameProcessor. In the CustomBackgroundFilterVideoFrameProcessor file, add VideoRotation.Rotation180 to the VideoFrame. And it worked
