Variable containing one member of the WMT_PLAY_MODE enumeration type.

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.


The default play mode is WMT_PLAY_MODE_AUTOSELECT, which enables the reader to pick the mode. If the application selects a play mode that is incompatible with the requested URL, an error is returned when the URL is opened. After the asynchronous reply to the Open request is completed, the mode is changed from WMT_PLAY_MODE_AUTOSELECT to the appropriately selected play mode. The play mode cannot be changed after the content has been opened, and returns an error if this is attempted.
