ImageFormat#YUV_420_888 is one of the most common image format supported by Android Cameras. It's a multi-plane YUV (YCbCr) format represented by three separate planes in android.media.Image.This format can be used for processing the input frames before saving to disk or some other action. It follows the YUV_420_888 logic as shown in this Wikipedia illustration. However, here we have three separate image planes for the Y, U and V-channels, thus I take these as three byte[], i.e. U8 allocations. . the android.media.Image, where only JPEG / YUV_420_888 formats are supported at this moment and YUV_420_888 is more efficient for all our APIs. rotationDegrees: the image's counter-clockwise orientation degrees. Only 0, 90, 180, 270 are supported. IllegalArgumentException will be thrown if the input degree is not in the list.Media the android.media.Image, where only JPEG / YUV_420_888 formats are supported at this moment and YUV_420_888 is more efficient for all our APIs. rotationDegrees: the image's counter-clockwise orientation degrees.
