Description
GstGLColorConvert is an object that converts between color spaces and/or formats using OpenGL Shaders.
A GstGLColorConvert can be created with gst_gl_color_convert_new(), the
configuration negotiated with gst_gl_color_convert_transform_caps() and the
conversion performed with gst_gl_color_convert_perform().
The glcolorconvertelement provides a GStreamer element that uses GstGLColorConvert to convert between video formats and color spaces.
Functions
gst_gl_color_convert_new ()
GstGLColorConvert *
gst_gl_color_convert_new (GstGLContext *context);
Since: 1.4
gst_gl_color_convert_set_caps ()
gboolean gst_gl_color_convert_set_caps (GstGLColorConvert *convert,GstCaps *in_caps,GstCaps *out_caps);
Initializes convert
with the information required for conversion.
Since: 1.6
