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().

For handling stride scaling in the shader, see gst_gl_color_convert_set_texture_scaling().

Details

GST_GL_COLOR_CONVERT_FORMATS

#define             GST_GL_COLOR_CONVERT_FORMATS

The currently supported formats that can be converted


GST_GL_COLOR_CONVERT_VIDEO_CAPS

#define GST_GL_COLOR_CONVERT_VIDEO_CAPS GST_VIDEO_CAPS_MAKE (GST_GL_COLOR_CONVERT_FORMATS)

The currently supported GstCaps that can be converted


GstGLColorConvert

typedef struct _GstGLColorConvert GstGLColorConvert;

Opaque GstGLColorConvert object


GstGLColorConvertClass

typedef struct {
  GstObjectClass object_class;
} GstGLColorConvertClass;

The GstGLColorConvertClass struct only contains private data


gst_gl_color_convert_new ()

GstGLColorConvert * gst_gl_color_convert_new            (GstGLContext *context);

context :

a GstGLContext

Returns :

a new GstGLColorConvert object

gst_gl_color_convert_set_format ()

void                gst_gl_color_convert_set_format     (GstGLColorConvert *convert,
                                                         GstVideoInfo *in_info,
                                                         GstVideoInfo *out_info);

Initializes convert with the information required for conversion.

convert :

a GstGLColorConvert

in_info :

input GstVideoInfo

out_info :

output GstVideoInfo

gst_gl_color_convert_perform ()

GstBuffer *         gst_gl_color_convert_perform        (GstGLColorConvert *convert,
                                                         GstBuffer *inbuf);

Converts the data contained by inbuf using the formats specified by the GstVideoInfos passed to gst_gl_color_convert_set_format()

convert :

a GstGLColorConvert

inbuf :

the texture ids for input formatted according to in_info

Returns :

a converted GstBuffer or NULL%
