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().
#define GST_GL_COLOR_CONVERT_FORMATS
The currently supported formats that can be converted
#define GST_GL_COLOR_CONVERT_VIDEO_CAPS GST_VIDEO_CAPS_MAKE (GST_GL_COLOR_CONVERT_FORMATS)

typedef struct _GstGLColorConvert GstGLColorConvert;
Opaque GstGLColorConvert object
typedef struct {
GstObjectClass object_class;
} GstGLColorConvertClass;
The GstGLColorConvertClass struct only contains private data

a GstGLContext |
Returns : |
a new GstGLColorConvert object |
void gst_gl_color_convert_set_format (GstGLColorConvert *convert,GstVideoInfo *in_info,GstVideoInfo *out_info);
Initializes convert with the information required for conversion.

output GstVideoInfo |
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()
|
a GstGLColorConvert |
|
the texture ids for input formatted according to in_info |
Returns : |
a converted GstBuffer or NULL% |
