Constructor Detail

CVPixelBuffer

public CVPixelBuffer(long ptr)

Initializes a new CVPixelBuffer instance which is to represent a specific CoreVideo CVPixelBufferRef.

Parameters:

ptr - the CoreVideo CVPixelBufferRef to be represented by the new instance

Method Detail

getByteCount

public int getByteCount()

Gets the number of bytes which represent the pixels of the associated CoreVideo CVPixelBufferRef.

Returns:

the number of bytes which represent the pixels of the associated CoreVideo CVPixelBufferRef

getBytes

public byte[] getBytes()

Gets a byte array which represents the pixels of the associated CoreVideo CVPixelBufferRef.

Returns:

a byte array which represents the pixels of the associated CoreVideo CVPixelBufferRef

getBytes

public int getBytes(long buf,
                    int bufLength)

Gets the bytes which represent the pixels of the associated CVPixelBufferRef into a specific native byte buffer with a specific capacity.

Parameters:

buf - the native byte buffer to return the bytes into

bufLength - the capacity in bytes of buf

Returns:

the number of bytes written into buf

getHeight

public int getHeight()

Gets the height in pixels of this CVPixelBuffer.

Returns:

the height in pixels of this CVPixelBuffer

getWidth

public int getWidth()

Gets the width in pixels of this CVPixelBuffer.

Returns:

the width in pixels of this CVPixelBuffer

memcpy

public static void memcpy(byte[] dst,
                          int dstOffset,
                          int dstLength,
                          long src)

Native copy from native pointer src to byte array dst.

Parameters:

dst - destination array

dstOffset - offset of dst to copy data to

dstLength - length of dst

src - native pointer source
