gst_video_blend_scale_linear_RGBA

gst_video_blend_scale_linear_RGBA (GstVideoInfo * src,
                                   GstBuffer * src_buffer,
                                   gint dest_height,
                                   gint dest_width,
                                   GstVideoInfo * dest,
                                   GstBuffer ** dest_buffer)

Scales a buffer containing RGBA (or AYUV) video. This is an internal helper function which is used to scale subtitle overlays, and may be deprecated in the near future. Use GstVideoScaler to scale video buffers instead.

Parameters:

src –

the GstVideoInfo describing the video data in src_buffer

src_buffer –

the source buffer containing video pixels to scale

dest_height –

the height in pixels to scale the video data in src_buffer to

dest_width –

the width in pixels to scale the video data in src_buffer to

dest ( [out]) –

pointer to a GstVideoInfo structure that will be filled in with the details for dest_buffer

dest_buffer ( [out]) –

a pointer to a GstBuffer variable, which will be set to a newly-allocated buffer containing the scaled pixels.

GstVideo.prototype.video_blend_scale_linear_RGBA

    // javascript wrapper for 'gst_video_blend_scale_linear_RGBA'
}

Parameters:

src (GstVideo.VideoInfo) –

the GstVideo.VideoInfo describing the video data in src_buffer

src_buffer (Gst.Buffer) –

the source buffer containing video pixels to scale

dest_height (Number) –

the height in pixels to scale the video data in src_buffer to

dest_width (Number) –

the width in pixels to scale the video data in src_buffer to

GstVideo.video_blend_scale_linear_RGBA

def GstVideo.video_blend_scale_linear_RGBA (src, src_buffer, dest_height, dest_width):
    #python wrapper for 'gst_video_blend_scale_linear_RGBA'

Parameters:

src (GstVideo.VideoInfo) –

the GstVideo.VideoInfo describing the video data in src_buffer

src_buffer (Gst.Buffer) –

the source buffer containing video pixels to scale

dest_height (int) –

the height in pixels to scale the video data in src_buffer to

dest_width (int) –

the width in pixels to scale the video data in src_buffer to
