KsGetMediaType function

Description

The KsGetMediaType function retrieves information about a media type on a pin factory identifier.

Parameters

Position [in]

Offset into the data range item that KsGetMediaType fills. Note that the data type of Position is int to conform to underlying calls.

AmMediaType [out]

Pointer to a variable that receives information in a AM_MEDIA_TYPE structure.

FilterHandle [in]

Handle to the filter that contains the pin factory to query.

PinFactoryId [in]

Identifier of the pin factory against which the information for a media type is being returned.

Return value

Returns NOERROR if successful; otherwise, returns an error code.

Remarks

The KsGetMediaType function queries the list of data ranges and performs a data intersection on the specified data range, thus producing a data format. It then converts that data format to a media type.

For more information about AM_MEDIA_TYPE, see the Microsoft Windows SDK documentation.
