Method Details

getType

VideoFrame.TextureBuffer.Type getType()

getTextureId

int getTextureId()

getTransformMatrix

android.graphics.Matrix getTransformMatrix()

Retrieve the transform matrix associated with the frame. This transform matrix maps 2D homogeneous coordinates of the form (s, t, 1) with s and t in the inclusive range [0, 1] to the coordinate that should be used to sample that location from the buffer.

applyTransformMatrix

default VideoFrame.TextureBuffer applyTransformMatrix(android.graphics.Matrix transformMatrix,
 int newWidth,
 int newHeight)

Create a new TextureBufferImpl with an applied transform matrix and a new size. The existing buffer is unchanged. The given transform matrix is applied first when texture coordinates are still in the unmodified [0, 1] range.

getUnscaledWidth

default int getUnscaledWidth()

Returns the width of the texture in memory. This should only be used for downscaling, and you should still respect the width from getWidth().

getUnscaledHeight

default int getUnscaledHeight()

Returns the height of the texture in memory. This should only be used for downscaling, and you should still respect the height from getHeight().
