Direction – sink

Object type – GstPad

## Signals

### begin-draw

    begin_draw_callback (GstElement * videosink,
                         gpointer udata)

    def begin_draw_callback (videosink, udata):
        #python callback for the 'begin-draw' signal

    function begin_draw_callback(videosink: GstElement * videosink, udata: gpointer udata): {
        // javascript callback for the 'begin-draw' signal
    }

Emitted when sink has a texture to draw. Application needs to invoke draw action signal before returning from begin-draw signal handler.

Parameters:

`videosink` –

the d3d11videosink

`udata` –
No description available

Flags: Run Last

Since : 1.20 Deprecated, Use appsink to access GStreamer produced D3D11 texture

### present

    present_callback (GstElement * videosink,
                      GstObject * device,
                      gpointer render_target,
                      gpointer udata)

    def present_callback (videosink, device, render_target, udata):
        #python callback for the 'present' signal

    function present_callback(videosink: GstElement * videosink, device: GstObject * device, render_target: gpointer render_target, udata: gpointer udata): {
        // javascript callback for the 'present' signal
    }

Emitted just before presenting a texture via the IDXGISwapChain::Present. The client can perform additional rendering on the given render_target, or can read the content already rendered on the swapchain's backbuffer.

This signal will be emitted with gst_d3d11_device_lock taken and client should perform GPU operation from the thread where this signal emitted.

Parameters:

`videosink` –

the d3d11videosink

`device` –

a GstD3D11Device object

`render_target` –

a ID3D11RenderTargetView handle of swapchain's backbuffer

`udata` –

Since : 1.22

## Action Signals

### draw

    g_signal_emit_by_name (videosink, "draw", shard_handle, texture_misc_flags, acquire_key, release_key, &ret);

    ret = videosink.emit ("draw", shard_handle, texture_misc_flags, acquire_key, release_key)

    let ret = videosink.emit ("draw", shard_handle, texture_misc_flags, acquire_key, release_key);

Draws on a shared texture. shard_handle must be a valid pointer to a HANDLE which was obtained via IDXGIResource::GetSharedHandle or IDXGIResource1::CreateSharedHandle.

If the texture was created with D3D11_RESOURCE_MISC_SHARED_KEYEDMUTEX flag, caller must specify valid acquire_key and release_key. Otherwise (i.e., created with D3D11_RESOURCE_MISC_SHARED flag), acquire_key and release_key will be ignored.

Parameters:

`videosink` (GstElement *) –

the d3d11videosink

`shard_handle` (gpointer) –

a pointer to HANDLE

`texture_misc_flags` (guint) –

a D3D11_RESOURCE_MISC_FLAG value

`acquire_key` (guint64) –

a key value used for IDXGIKeyedMutex::AcquireSync

`release_key` (guint64) –

a key value used for IDXGIKeyedMutex::ReleaseSync

Returns (gboolean) –
No description available

Flags: Run Last / Action

Since : 1.20 As of 1.24, @acquire_key and @release_key must be zero. Other values are not supported. Deprecated, Use appsink to access GStreamer produced D3D11 texture
