Finding MediaLocation for a page item

Hi,

I'm writing an InDesign plugin which needs to query the MediaLocation for any given movie on a page.

I've found 2 ways of doing this: firstly by selecting the page item and accessing the location via IMediaSuite:

IActiveContext* iActiveContext = GetExecutionContextSession()->GetActiveContext ();

ISelectionManager* iSelectionManager = iActiveContext->GetContextSelection();

InterfacePtr<IMediaSuite> ms(iSelectionManager, UseDefaultIID());

if (ms) {

  MediaLocation loc;

  ms->GetMediaLocation(loc);

}

However, ideally I'd like to not have to select the page item first.

The second way I found avoids having to select it, but does not work for remote movies as they have no link:

UID linkUID = Utils<ILinkUtils>()->FindLink(item);

InterfacePtr<ILinkManager> linkManager(db, db->GetRootUID(), UseDefaultIID());

ILink* link = linkManager->QueryLinkByUID(linkUID);

InterfacePtr<const ILinkObject> linkObj(::GetDataBase(link),link->GetObject(),UseDefaultIID());

InterfacePtr<const IMediaInfo> mediaInfo((IMediaInfo*)linkObj->QueryLinkedObject(IID_IMEDIAINFO));

InterfacePtr<const IMediaContent> mediaContent(mediaInfo,UseDefaultIID());

MediaLocation loc = mediaContent->GetLocation();

Is there a way I can get the MediaLocation for both local and remote movies, without first having to select the page item?

Thanks

Liz
