rtsp playback regression in VLCKit 3.3.17 on iOS/tvOS devices on iOS14

"I'v known it's a problem of iPhone 11, 12 but it's wrong. it happen a problem on iOS 14.7.1."

When play the video of device connected local network, it happen to a critical problem on iPhone 11, 12. The low version iPhone is no problem.(6s, 8 etc.) The video is crashed and force stop except the version 3.3.17 on iPhone 11, 12...

So we had to change the version 3.1.5 to 3.3.17. But still have a problem.

Truly, I don't understand why it happen this problem.

3.3.17 has a unnormal problem too.

It basically doesn't work. After connecting the our black box camera device to the network and running the realtime video, only a black screen is visible. And it can't stream the local video of the blackbox camera device. (Of course, this doesn't happen with the iPhone 6 and 8s.) but connect with Mac, it works well. ^ ^ ;;;;;;

I hope help me.

Thanks to read this issue.
