Struct gstreamer_gl::GLColorConvert[−][src]

pub struct GLColorConvert(_);

Expand description

GLColorConvert is an object that converts between color spaces and/or formats using OpenGL Shaders.

A GLColorConvert can be created with new(), the configuration negotiated with transform_caps() and the conversion performed with gst_gl_color_convert_perform().

The glcolorconvertelement provides a GStreamer element that uses GLColorConvert to convert between video formats and color spaces.

Implements

gst::prelude::ObjectExt, trait@glib::ObjectExt
