Hello there i am developing android app using dji's msdk and my baseline use-case is to stream video to computer.
well for now what issue i am facing is that i need to get encoded raw video frames from drone but to get it LensDistortionCalibration should be done i have calibrated drone 2 time but still same results.

Here it says that it isLensDistortionCalibrationNeeded should return false to get raw frames so can anyone help me on how i can calibrate lens distortion ?

Thanks for reply but i need was to know if there is any calibration routine for drone so that i can call it in my app and fix the problem programmatically.
One solution that i have found is that dji provides external anti-distortion library for same scanerio now i am exploring it.

Would that be DJI TERRA by any chance? This does automatically recognise specific DJI camera profiles and offers an 'undistortion' switch, so somewhere in a subfolder there will be dat files containing factory accurate distortion correction parameters.... Hmmmm..... definitely worth a look.
