I have the functionality to get the frame from IFrameCallback and pass it to other third-party libraries. but IFrameCallback does not provide frame every time. Sometimes randomly stop providing frames. I have successfully setPreviewSize, setPreviewTexture, startPreview, but I get nothing on onFrame. Why is it so?
In this same case, UVC camera also crashed when I stop the Preview.
