IXml2Dex::ReadXMLFile method

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Note

[Deprecated. This API may be removed from future releases of Windows.]

 

The ReadXMLFile method loads an XML project file. This method creates instances of all the objects expressed in the XML file and inserts them into the timeline, as well as applying any attributes given for the timeline, such as frame rate or default effect.

Syntax

HRESULT ReadXMLFile(
   IUnknown *pTimeline,
   BSTR     XMLName
);

Parameters

pTimeline

Pointer to a timeline object's IUnknown interface.

XMLName

String that specifies the name of the file to load.

Return value

Returns an HRESULT value. Possible values include the following.

Return code	Description
S_OK	Success
VFW_E_INVALID_FILE_FORMAT	Invalid file format

 

Remarks

This method does not clear existing objects from the timeline before it inserts the new objects defined in the XML file. If you need to refresh an existing timeline, call IAMTimeline::ClearAllGroups first.
