Find camera's parameters of frame in OpenCV on Android -


i know if there way camera's parameters when process video frame frame using opencv on android phones. example, know exposure time (not exposure compensation) of each frame or other information (like iso) active camera properties.

one obvious answer set camera parameters myself , set exposure lock willing find exact exposure time (such 1/2000 sec). there way on every new captured frame? know can add attributes jpeg photo exifinterface not know how obtain values.

one possible use case not process frames taken exposure time below predefined value.

thank you!

no there not. info not come frame, , if try check sensor registers while processing frame, may have changed.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
