VideoOverlayRectangle.newRaw

Creates a new video overlay rectangle with ARGB or AYUV pixel data. The layout in case of ARGB of the components in memory is B-G-R-A on little-endian platforms (corresponding to #GST_VIDEO_FORMAT_BGRA) and A-R-G-B on big-endian platforms (corresponding to #GST_VIDEO_FORMAT_ARGB). In other words, pixels are treated as 32-bit words and the lowest 8 bits then contain the blue component value and the highest 8 bits contain the alpha component value. Unless specified in the flags, the RGB values are non-premultiplied. This is the format that is used by most hardware, and also many rendering libraries such as Cairo, for example. The pixel data buffer must have #GstVideoMeta set.

Parameters

pixels gst.buffer.Buffer: a #GstBuffer pointing to the pixel memory
renderX int: the X co-ordinate on the video where the top-left corner of this overlay rectangle should be rendered to
renderY int: the Y co-ordinate on the video where the top-left corner of this overlay rectangle should be rendered to
renderWidth uint: the render width of this rectangle on the video
