Strange Behavior with adding to Media Library (WM10) with C |
|
|
Greetings,
I'm attempting to add a single avi to the media library using C++.
Everything runs ok without error. However after my program finishes
executing, the added media does not show up in the Window Media Player
Library.
Am I missing some important call? Some sort of flush call? Does "Add"
requires some minimum item setting e.g. IWMPMedia::setItemInfo
Notes:
- Stepping through with the debugger: all calls return successfully (S_OK)
- The avi is in the media collection of my program if I enumerate after the
add (only during program instance).
- IWMPSettings2::get_mediaAccessRights returns "full"
- Windows Media Player v10 installed, WMSDK v10 installed, Windows XP
(Service Pack 1)
- Unicode Build
Any Ideas?
Thanks,
Code snippit below (bare minimums)
-----------------------------------------
#include <atlbase.h>
#include <atlwin.h>
#include "wmp.h"
CoInitialize(NULL);
// IWMPPlayer
CComPtr<IWMPPlayer4> spPlayer;
HRESULT hr = spPlayer.CoCreateInstance(__uuidof(WindowsMediaPlayer), 0,
CLSCTX_INPROC_SERVER);
// IWMPSettings
CComPtr<IWMPSettings> spSet;
hr = spPlayer->get_settings(&spSet);
// Get Settings2 interface
CComPtr<IWMPSettings2> spSet2;
hr = spSet.QueryInterface(&spSet2);
// get rights
CComBSTR sRights;
hr = spSet2->get_mediaAccessRights(&sRights);
// IWMPMediaCollection
CComPtr<IWMPMediaCollection> spMediaCollection;
hr = spPlayer->get_mediaCollection(&spMediaCollection);
CComPtr<IWMPMedia> spNewMedia;
hr = spMediaCollection->add(L"c:\\media\\test.avi", &spNewMedia);
CoUnitialize();

The changes won't commit until the next time the Player runs. If you want it
to commit right away, create a remoted instance of the control.
