Accepts an ASF packet for the file and creates index entries for them.
Pointer to the IMFSample interface of a media sample that contains the ASF packet.
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
The argument passed in is NULL. |
|
The indexer is not initialized. |
The ASF indexer creates indexes for a file internally. You can get the completed index for all data packets sent to the indexer by committing the index with IMFASFIndexer::CommitIndex and then calling IMFASFIndexer::GetCompletedIndex to write the index entries into a media buffer. To determine the size of the index so you can allocate a buffer large enough to hold the index, call IMFASFIndexer::GetIndexWriteSpace.
When this method creates index entries, they are immediately available for use by IMFASFIndexer::GetSeekPositionForValue.
The media sample specified in pIASFPacketSample must hold a buffer that contains a single ASF packet. Get the sample from the ASF multiplexer by calling the IMFASFMultiplexer::GetNextPacket method.
You cannot use this method while reading an index, only when writing an index.
