Constructor and Description
AVFrame() Initializes a new FinalizableAVFrame instance which is to allocate a new native FFmpeg AVFrame and represent it.
AVFrame(long ptr) Initializes a new AVFrame instance which is to represent a specific pointer to a native FFmpeg AVFrame object.

Method Summary

Modifier and Type	Method and Description
int	avpicture_fill(ByteBuffer data, AVFrameFormat format)

Constructor Detail

AVFrame

public AVFrame()

Initializes a new FinalizableAVFrame instance which is to allocate a new native FFmpeg AVFrame and represent it.

AVFrame

public AVFrame(long ptr)

Initializes a new AVFrame instance which is to represent a specific pointer to a native FFmpeg AVFrame object. Because the native memory/AVFrame has been allocated outside the new instance, the new instance does not automatically free it upon finalization.

Parameters:

ptr - the pointer to the native FFmpeg AVFrame object to be represented by the new instance

Method Detail

read

public static int read(javax.media.Buffer buffer,
                       javax.media.Format format,
                       ByteBuffer data)

avpicture_fill

public int avpicture_fill(ByteBuffer data,
                          AVFrameFormat format)

finalize

protected void finalize()
                 throws Throwable

Deallocates the native memory/FFmpeg AVFrame object represented by this instance if this instance has allocated it upon initialization and it has not been deallocated yet i.e. ensures that free() is invoked on this instance.

Overrides:

finalize in class Object

Throws:

Throwable

See Also:

Object.finalize()

free

public void free()

Deallocates the native memory/FFmpeg AVFrame object represented by this instance if this instance has allocated it upon initialization and it has not been deallocated yet.

getData

public ByteBuffer getData()

Gets the ByteBuffer whose native memory is set on the native counterpart of this instance/AVFrame.

Returns:

the ByteBuffer whose native memory is set on the native counterpart of this instance/AVFrame.

getPtr

public long getPtr()

Gets the pointer to the native FFmpeg AVFrame object represented by this instance.

Returns:

the pointer to the native FFmpeg AVFrame object represented by this instance
