The portion of the file holding the video data. The video data might be compressed to save disk space. The data has to be decompressed using a video decompressor before you can play (see) it.

Also known as a decoder, this is a module or algorithm to decompress data.

IltmmWMProfile::CreateNewStream

Show in webframe

#include "ltmm.h"

C Syntax	HRESULT IltmmWMProfile_CreateNewStream(pProfile, StreamType, pVal)
C++ Syntax	HRESULT CreateNewStream(StreamType, pVal)

IltmmWMProfile *pProfile;	/* pointer to an interface */
BSTR StreamType;	/* string */
IltmmWMStreamConfig **pVal;	/* pointer to a pointer */

Creates a new stream configuration object that can be used to describe a media stream in the profile.

Parameter	Description
pProfile	Pointer to an IltmmWMProfile interface.
StreamType	A CLSID string specifying the requested stream type GUID. Possible values are:
	Value	Meaning
	ltmmMEDIATYPE_Video	Video stream
	ltmmMEDIATYPE_Audio	Audio stream
	ltmmMEDIATYPE_Text	Script stream
pVal	Pointer to a variable to be updated with a pointer to an IltmmWMStreamConfig interface. This interface references the newly created stream configuration object.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

For more information on the support media types, refer to section of Formats, Media Types and Media Subtypes.

If IltmmWMProfile::CreateNewStream succeeds, the caller must free the retrieved interface by calling its Release method.

Please note that creating a new stream does not automatically add it to the profile. The new stream must be created using IltmmWMProfile::CreateNewStream, and then configured using the IltmmWMStreamConfig interface. The configured stream must then be added to the profile using IltmmWMProfile::AddStream.

For more information, refer to the Microsoft documentation for IWMProfile::CreateNewStream .
