GuidNames

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

GuidNames is a global array in the DirectShow base class library that contains strings representing the GUIDs defined in Uuids.h. This array is useful for generating debug output.

char* GuidNames[guid]

Parameters

guid

Specifies any GUID value defined in the header file Uuids.h.

Remarks

Use this global array to output GUID constants as strings. For example, the following code prints the string "MEDIATYPE_Video" to the console:

puts(GuidNames[MEDIATYPE_Video]);

If the GUID is not matched, the string "Unknown GUID Name" is returned. Not all DirectShow GUIDs are defined in uuids.h.

Requirements

Header
Wxdebug.h (include Streams.h)
Library
