Constructor Detail

NV21Buffer

public NV21Buffer(byte[] data,
                  int width,
                  int height,
                  @Nullable
                  java.lang.Runnable releaseCallback)

Method Detail

getWidth

public int getWidth()

Description copied from interface: VideoFrame.Buffer

Resolution of the buffer in pixels.

Specified by:

getWidth in interface VideoFrame.Buffer

getHeight

public int getHeight()

Specified by:

getHeight in interface VideoFrame.Buffer

toI420

public VideoFrame.I420Buffer toI420()

Description copied from interface: VideoFrame.Buffer

Returns a memory-backed frame in I420 format. If the pixel data is in another format, a conversion will take place. All implementations must provide a fallback to I420 for compatibility with e.g. the internal WebRTC software encoders.

Specified by:

toI420 in interface VideoFrame.Buffer

retain

public void retain()

Description copied from interface: RefCounted

Increases ref count by one.

Specified by:

retain in interface RefCounted

Specified by:

retain in interface VideoFrame.Buffer

release

public void release()

Description copied from interface: RefCounted

Decreases ref count by one. When the ref count reaches zero, resources related to the object will be freed.

Specified by:

release in interface RefCounted

Specified by:

release in interface VideoFrame.Buffer

cropAndScale

public VideoFrame.Buffer cropAndScale(int cropX,
                                      int cropY,
                                      int cropWidth,
                                      int cropHeight,
                                      int scaleWidth,
                                      int scaleHeight)

Description copied from interface: VideoFrame.Buffer

Crops a region defined by |cropx|, |cropY|, |cropWidth| and |cropHeight|. Scales it to size |scaleWidth| x |scaleHeight|.

Specified by:

cropAndScale in interface VideoFrame.Buffer
