Configures an Advanced Systems Format (ASF) mutual exclusion object, which manages information about a group of streams in an ASF profile that are mutually exclusive. When streams or groups of streams are mutually exclusive, only one of them is read at a time, they are not read concurrently.
A common example of mutual exclusion is a set of streams that each include the same content encoded at a different bit rate. The stream that is used is determined by the available bandwidth to the reader.
An IMFASFMutualExclusion interface exists for every ASF mutual exclusion object. A pointer to this interface is obtained when you create the object using the IMFASFProfile::CreateMutualExclusion method.
Inheritance
The IMFASFMutualExclusion interface inherits from the IUnknown interface. IMFASFMutualExclusion also has these types of members:
Methods
The IMFASFMutualExclusion interface has these methods.
| IMFASFMutualExclusion::AddRecord Adds a record to the mutual exclusion object. A record specifies streams that are mutually exclusive with the streams in all other records. |
| IMFASFMutualExclusion::AddStreamForRecord Adds a stream number to a record in the Advanced Systems Format mutual exclusion object. |
| IMFASFMutualExclusion::Clone Creates a copy of the Advanced Systems Format mutual exclusion object. |
| IMFASFMutualExclusion::GetRecordCount Retrieves the number of records in the Advanced Systems Format mutual exclusion object. |
| IMFASFMutualExclusion::GetStreamsForRecord Retrieves the stream numbers contained in a record in the Advanced Systems Format mutual exclusion object. |
| IMFASFMutualExclusion::GetType Retrieves the type of mutual exclusion represented by the Advanced Systems Format (ASF) mutual exclusion object. |
| IMFASFMutualExclusion::RemoveRecord Removes a record from the Advanced Systems Format (ASF) mutual exclusion object. |
| IMFASFMutualExclusion::RemoveStreamFromRecord Removes a stream number from a record in the Advanced Systems Format mutual exclusion object. |
| IMFASFMutualExclusion::SetType Sets the type of mutual exclusion that is represented by the Advanced Systems Format (ASF) mutual exclusion object. |
Remarks
An ASF profile object can support multiple mutual exclusions. Each must be configured using a separate ASF mutual exclusion object.
