Camera opened, but the preview screen tearing and black screen. #20

Open YXwong01 opened 3 months ago

YXwong01 commented 3 months ago

I tried the demo project provided, and it works perfectly fine on my Samsung (Android 12), but I'm facing some issues on my other devices, namely Vivo (Android 12) and Honor (Android 12).

I've tried both frame formats: 0 and 1. With frame format 1, I get a black screen preview, and with frame format 0, I encounter tearing on the screen.

Below are my log messages and some pictures showing the tearing issue. Could you please assist me with this?

Here is the log when using fram formats 1

@YXwong01 Hi! Some devices are not compatible, have you tried switching resolutions enough?
