[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
Removes the mapping between a stream and an output pin for a Stream Buffer Source filter. After a successful call to this method, the output pin stops sending media samples. To resume sending media samples, the pin must be mapped to another stream by a call to the MapStream method.
By default, the stream mappings cannot be changed. Before calling this method, disable the default mapping mode by calling the ISBE2Crossbar::EnableDefaultMode method without the DEF_MODE_STREAMS flag.
Syntax
HRESULT UnmapStream(
[in] SBE2_STREAM_ID Stream
);
Parameters
[in] Stream
Identifier for the stream. This stream will be unmapped from the output pin.
Return value
| Return code | Description |
|---|---|
|
The specified stream does not exist or was not previously mapped to a pin. |
|
Success. |
|
Cannot unmap the stream, because the default mode is enabled. |
