Example

Here is example of how to fill all elements in the scene with the same source:

Visual Basic
C#
Delphi

Dim myMixer As New MMixerClass()
myMixer.ScenesActiveGet(mySceneID, myIndex, myScene)
Dim pChild As MElement
myScene.ElementsAdd("newElem", "video", "stream_idx=0 h=0.5 w=0.5 show=1", pChild, 2.0)
Dim nCount As Integer
myScene.ElementsGetCount(nCount)
For i As Integer = 0 To nCount - 1
ElementsGetByIndex(i, myElement)
myElement.ElementMediaSet(Nothing, "d:\clips\SampleClip1.wmv", "", 2.0)
Next

MMixerClass myMixer = new MMixerClass();
myMixer.ScenesActiveGet(out mySceneID, out myIndex, out myScene);
MElement pChild;
myScene.ElementsAdd("newElem", "video", "stream_idx=0 h=0.5 w=0.5 show=1", out pChild, 2.0);
int nCount;
myScene.ElementsGetCount(out nCount);
for (int i=0; i<nCount; i++)
{
ElementsGetByIndex(i, out myElement);
myElement.ElementMediaSet(null, @"d:\clips\SampleClip1.wmv", "", 2.0);
}

var
myMixer: MMixer;
myScenes: IMScenes;
myScene: IMElements;
mySceneID: string;
myIndex: integer;
myElement: MElement;
i, nCount: integer;
begin
myMixer:= CreateComObject(CLASS_MMixer) as MMixer;
myScenes := myMixer as IMScenes;
myScenes.ScenesActiveGet(mySceneID, myIndex, myScene);
myScene.ElementsAdd('newElem', 'video', tream_idx=0 h=0.5 w=0.5 show=1', myElement, 2.0);
myScene.ElementsGetCount(nCount);
for i:=0 to nCount-1 do
begin
ElementsGetByIndex(i, myElement);
myElement.ElementMediaSet(nil, 'd:\clips\SampleClip1.wmv', '', 2.0);
end;
end;
