Implementation of VideoFrame.I420Buffer backed by Java direct byte buffers.

Properties

open fun allocate(width: Int, height: Int): JavaI420Buffer

Allocates an empty I420Buffer suitable for an image of the given dimensions.

open fun cropAndScale(cropX: Int, cropY: Int, cropWidth: Int, cropHeight: Int, scaleWidth: Int, scaleHeight: Int): VideoFrame.Buffer

Crops a region defined by `cropx`, `cropY`, `cropWidth` and `cropHeight`.

open fun cropAndScaleI420(buffer: VideoFrame.I420Buffer, cropX: Int, cropY: Int, cropWidth: Int, cropHeight: Int, scaleWidth: Int, scaleHeight: Int): VideoFrame.Buffer

open fun release()

Decreases ref count by one.

open fun retain()

Increases ref count by one.

Returns a memory-backed frame in I420 format.

open fun wrap(width: Int, height: Int, dataY: ByteBuffer, strideY: Int, dataU: ByteBuffer, strideU: Int, dataV: ByteBuffer, strideV: Int, @Nullable releaseCallback: Runnable): JavaI420Buffer

Wraps existing ByteBuffers into JavaI420Buffer object without copying the contents.
