According to gstinspect of nvarguscamerasrc, exposurecompensation (property to adjust exposure compensation) have range from -2.0f to 2.0f and it’s perfectly works while exposure in automatic mode.
While in manual it works only in the range 0.0f to 2.0f, but in case of negative value error of initialization appear: Error initializing: Unknown option -2.0
Hardware - Jetson Nano A/RaspberryPi cam v2/ Jetpack 4.5.1 [L4T 32.5.1]
code to test - crash with -2.0…-0.0, works as expected in 0.0…2.0, everything above 2.0 is just ignored

Can someone confirm this issue?
Thank you in advance.
