12 //-----------------Introduction----------------------------------------------
13 // This backend is for Desktops with either WMP 9 or 10 and Windows
14 // mobile (5.0, some 2003 SmartPhones etc.) WMP 10 only (9 has no automation
15 // interface but you can hack it with message hacks to play through
16 // a currently running instance of media player).
17 //
18 // There are quite a few WMP 10 interfaces and unlike other media
19 // backends we actually set it to automatically play files as it has
20 // as huge caveat that you cannot (technically) obtain media information
21 // from IWMPMedia including duration and video size until a media file
22 // has literally started to play. There is a hack (and indeed we have
23 // it within this file) to enable duration getting from a non-playing
24 // file, but there is no hack I (RN) know of to get the video size from
25 // a file that isn't playing.
26 //
27 // The workaround for this is to send the wxEVT_MEDIA_LOADED when the file
28 // is about to be played - and if the user didn't change the state of the
29 // media (m_bWasStateChanged), when set it back to the stop state.
30 //
31 // The ActiveX control itself is particularily stubborn, calling
32 // IOleInPlaceSite::OnPosRectChange every file change trying to set itself
33 // to something different then what we told it to before.
34 //
