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.
