typedef struct _GstVaapiWindowGLX GstVaapiWindowGLX;
An X11 Window suitable for GLX rendering.
GstVaapiWindow * gst_vaapi_window_glx_new (GstVaapiDisplay *display,guint width,guint height);
Creates a window with the specified width and height. The window
will be attached to the display and remains invisible to the user
until gst_vaapi_window_show() is called.
|
a GstVaapiDisplay |
|
the requested window width, in pixels |
|
the requested windo height, in pixels |
Returns : |
the newly allocated GstVaapiWindow object |
GstVaapiWindow * gst_vaapi_window_glx_new_with_xid (GstVaapiDisplay *display,Window xid);
Creates a GstVaapiWindow using the X11 Window xid. The caller
still owns the window and must call XDestroyWindow() when all
GstVaapiWindow references are released. Doing so too early can
yield undefined behaviour.
|
a GstVaapiDisplay |
|
an X11 Window id |
Returns : |
the newly allocated GstVaapiWindow object |
GLXContext gst_vaapi_window_glx_get_context (GstVaapiWindowGLX *window);
Returns the GLXContext bound to the window.
|
a GstVaapiWindowGLX |
Returns : |
the GLXContext bound to the window
|
gboolean gst_vaapi_window_glx_set_context (GstVaapiWindowGLX *window,GLXContext ctx);
Binds GLX context ctx to window. If ctx is non NULL, the caller
is responsible to making sure it has compatible visual with that of
the underlying X window. If ctx is NULL, a new context is created
and the window owns it.
|
a GstVaapiWindowGLX |
|
a GLX context |
Returns : |
TRUE on success |
gboolean gst_vaapi_window_glx_make_current (GstVaapiWindowGLX *window);
Makes the window GLX context the current GLX rendering context of
the calling thread, replacing the previously current context if
there was one.
|
a GstVaapiWindowGLX |
Returns : |
TRUE on success |
void gst_vaapi_window_glx_swap_buffers (GstVaapiWindowGLX *window);
Promotes the contents of the back buffer of window to become the
contents of the front buffer of window. This simply is wrapper
around glXSwapBuffers().
|
a GstVaapiWindowGLX |
gboolean gst_vaapi_window_glx_put_texture (GstVaapiWindowGLX *window,GstVaapiTexture *texture,const GstVaapiRectangle *src_rect,const GstVaapiRectangle *dst_rect);
Renders the texture region specified by src_rect into the window
region specified by dst_rect.
NOTE: only GL_TEXTURE_2D textures are supported at this time.
|
a GstVaapiWindowGLX |
|
a GstVaapiTexture |
|
the sub-rectangle of the source texture to
extract and process. If NULL, the entire texture will be used. |
|
the sub-rectangle of the destination
window into which the texture is rendered. If NULL, the entire
window will be used. |
Returns : |
TRUE on success |
