ncnn-android-yolov4-tiny-custom's Issues

camera preview issues on lower end phones

Hi @SunnyGrocery ,

This is an amazing project!
It's working fine on my 4gb ram phone , but on my 1gb ram device with 1.3ghz cpu , it is having some issues.
Green lines are appearing on the imageview instead of the proper camera preview.
Hope you could suggest a fix, to get a proper camera preview output on the imageview.

I've attached a screenshot of the issue with the camera preview.
