GstSurfaceConverter — Interface for GstSurfaceBuffer convertion

Synopsis

                    GstSurfaceConverter;
                    GstSurfaceConverterInterface;
GType               gst_surface_converter_get_type      (void);
gboolean            gst_surface_converter_upload        (GstSurfaceConverter *converter,
                                                         GstSurfaceBuffer *buffer);

Description

Objects implementing this interface are used as a convertion context. This allow element optimizing the upload by keeping required resources between uploads. The context must be discarded when the pipeline goes to GST_STATE_NULL or renewed whenever the caps are changed.

Note

The GstVideoContext interface is unstable API and may change in future. One can define GST_USE_UNSTABLE_API to acknowledge and avoid this warning.

Example uploading to GL texture

if (G_UNLIKELY (priv->converter == NULL))
  priv->converter = gst_surface_buffer_create_converter (surface, "opengl", &value);

gst_surface_converter_uplaod (priv->converter, surface);

Details

GstSurfaceConverter

typedef struct _GstSurfaceConverter GstSurfaceConverter;

GstSurfaceConverterInterface

typedef struct {
  GTypeInterface parent;

  gboolean (*upload) (GstSurfaceConverter *converter,
                      GstSurfaceBuffer *buffer);
} GstSurfaceConverterInterface;

GstSurfaceConverterInterface interface.

GTypeInterface `parent`;	parent interface type.
`upload` ()	vmethod to upload GstSurfaceBuffer.

gst_surface_converter_get_type ()

GType               gst_surface_converter_get_type      (void);

gst_surface_converter_upload ()

gboolean            gst_surface_converter_upload        (GstSurfaceConverter *converter,
                                                         GstSurfaceBuffer *buffer);

Convert and uploads the GstSurfaceBuffer to the converter destination.

`converter` :	a GstSurfaceConverter
`buffer` :	the GstSurfaceBuffer to upload
Returns :	TRUE on success, FALSE otherwise
