VideoFrame

interface VideoFrame

Interface for representing video frame. Check color format by using VideoFrame.colorFormat. Most used format is ImageFormat.YUV_420_888 which is I420 format that uses planar or semi-planar (but not fully interleaved) memory layout - do not assume continuity and use use VideoFrame.yuvPlanes and VideoFrame.yuvStrides APIs to get correct start line of any plane. NB: do not assume that ByteBuffers of VideoFrame.yuvPlanes are backed by Java's byte[] arrays! Most probably frame you receive via this API is natively allocated and NOT backed by Java array. Use slow but secure ByteBuffer.put or better, your own native C++ processing via JNI.
