gstvideo.video_scaler

Module for VideoScaler class

Types 1

#GstVideoScaler is a utility object for rescaling and resampling video frames using various interpolation / sampling methods.

Fields

GstVideoScaler * _cInstancePtr

bool owned

Methods

void * _cPtr()

void _2d(gstvideo.video_scaler.VideoScaler vscale,  gstvideo.types.VideoFormat format,  void *  src,  int  srcStride,  void *  dest,  int  destStride,  uint  x,  uint  y,  uint  width,  uint  height)

Scale a rectangle of pixels in src with src_stride to dest with dest_stride using the horizontal scaler hscaler and the vertical scaler vscale.

const(double) * getCoeff(uint outOffset, out uint inOffset, out uint nTaps)For a given pixel at out_offset, get the first required input pixel at in_offset and the n_taps filter coefficients.

uint getMaxTaps()Get the maximum number of taps for scale. Returns: the maximum number of taps

void horizontal(gstvideo.types.VideoFormat format, void * src, void * dest, uint destOffset, uint width)Horizontally scale the pixels in src to dest, starting from dest_offset for width samples.
