Hello there i am developing android app using dji's msdk and my baseline usecase 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 ?

  Mavic 2 Pro/Zoom has lens distortion correction enabled by default. However, if the `isLensDistortionCalibrationNeeded` returns true, you will need to comment out the `exclude module: 'library-anti-distortion'` when relying on the SDK.

  After configuring the anti-distortion library, `isLensDistortionCalibrationNeeded` should be false, and the data from the videodataListner will also take effect.

  it works for this separate repo (specifically when custom decoder is selected) mentioned in docs.

  But when i try to just include  anti-distortion library (By commenting out exclude command in gradle file ) in my existing project then it does not work maybe i am not doing it correctly but anyhow i will try to find issue otherwise will try to build upon said library :)

  which interface you are using to retrieve the videoFeed？ If you are currently using getPrimaryVideoFeed, I suggest trying to replace it with provideTranscodedVideoFeed.
