GstVaapiTexture * gst_vaapi_texture_new (GstVaapiDisplay *display,GLenum target,GLenum format,guint width,guint height);
Creates a texture with the specified dimensions, target
and
format
. Note that only GL_TEXTURE_2D target
and GL_RGBA or
GL_BGRA formats are supported at this time.
The application shall maintain the live GL context itself. That is,
gst_vaapi_window_glx_make_current() must be called beforehand, or
any other function like glXMakeCurrent() if the context is managed
outside of this library.
GstVaapiTexture * gst_vaapi_texture_new_with_texture (GstVaapiDisplay *display,GLuint texture_id,GLenum target,GLenum format);
Creates a texture from an existing GL texture, with the specified
target
and format
. Note that only GL_TEXTURE_2D target
and
GL_RGBA or GL_BGRA formats are supported at this time. The
dimensions will be retrieved from the texture_id
.
The application shall maintain the live GL context itself. That is,
gst_vaapi_window_glx_make_current() must be called beforehand, or
any other function like glXMakeCurrent() if the context is managed
outside of this library.
GLuint
gst_vaapi_texture_get_id (GstVaapiTexture *texture);
Returns the underlying texture id of the texture
.
GLenum
gst_vaapi_texture_get_target (GstVaapiTexture *texture);
Returns the texture
target type
GLenum
gst_vaapi_texture_get_format (GstVaapiTexture *texture);
Returns the texture
format
guint
gst_vaapi_texture_get_width (GstVaapiTexture *texture);
Returns the texture
width.
guint
gst_vaapi_texture_get_height (GstVaapiTexture *texture);
Returns the texture
height.
void gst_vaapi_texture_get_size (GstVaapiTexture *texture,guint *pwidth,guint *pheight);
Retrieves the dimensions of a GstVaapiTexture.
gboolean gst_vaapi_texture_put_surface (GstVaapiTexture *texture,GstVaapiSurface *surface,guint flags);
Renders the surface
into the àtexture. The flags
specify how
de-interlacing (if needed), color space conversion, scaling and
other postprocessing transformations are performed.
