🐛 Failed to get maximum FPS for Camera ID 1

[francesco-clementi-92]

What's happening?

I'm trying to develop a frame processor plugin, but when I start my application I get the errors on android:

Failed to get maximum FPS for Camera ID 1! Attempt to invoke virtual method 'int android.media.EncoderProfiles$VideoProfile.getFrameRate()' on a null object reference
