Class AndroidFrameConverter

java.lang.Object

org.bytedeco.javacv.FrameConverter<Bitmap>

org.bytedeco.javacv.AndroidFrameConverter

All Implemented Interfaces:

AutoCloseable

public class AndroidFrameConverter
extends FrameConverter<Bitmap>

A utility class to copy data between Frame and Bitmap. Since Bitmap does not expose its internal buffer, we cannot share allocated memory with Frame.

This class is not optimized for speed. For best performance, convert first your data to and from RGBA with optimized functions from FFmpeg or OpenCV. Further, pixel formats other than grayscale, BGR, and RGBA are not well supported. Their conversions might fail in undefined ways.
