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