The FreeStreamingResources method frees resources allocated by the DMO. Calling this method is always optional.
Returns S_OK if successful. Otherwise, returns an HRESULT value indicating the cause of the error.
This method releases any resources that the IMediaObject::AllocateStreamingResources method initializes.
If the DMO does not support this method, the method returns S_OK. If you call this method during streaming, the method fails and the DMO does not release any resources.
Regardless of whether the method fails or succeeds, the application can continue to call other methods on the DMO. The DMO might need to re-initialize resources that were previously freed.
