+\section{\class{wxActiveXContainer}}\label{wxactivexcontainer}
+
+wxActiveXContainer is a host for an activex control on Windows (and
+as such is a platform-specific class). Note that the HWND that the class
+contains is the actual HWND of the activex control so using dynamic events
+and connecting to wxEVT\_SIZE, for example, will recieve the actual size
+message sent to the control.
+
+It is somewhat similar to the ATL class CAxWindow in operation.
+
+The size of the activex control's content is generally gauranteed to be that
+of the client size of the parent of this wxActiveXContainer.
+
+You can also process activex events through wxEVT\_ACTIVEX or the
+corresponding message map macro EVT\_ACTIVEX.

+\section{\class{wxActiveXEvent}}\label{wxactivexevent}
+
+An event class for handling activex events passed from
+\helpref{wxActiveXContainer}{wxactivexcontainer}. ActiveX events are basically
+a function call with the parameters passed through an array of wxVariants along
+with a return value that is a wxVariant itself. What type the parameters or
+return value are depends on the context (i.e. what the .idl specifies).
+
+Note that unlike the third party wxActiveX function names are not supported.

\membersection{Rendering media}\label{renderingmediawxmediactrl}
Depending upon the backend, wxMediaCtrl can render
the playback rate of certain streaming media - while DirectShow is
slightly more flexible in that regard.
+
\membersection{Operation}\label{operationwxmediactrl}
When wxMediaCtrl plays a file, it plays until the stop position
on them they return to the beginning, thus wxMediaCtrl tries
to keep consistant for all types of media.
+Note that when changing the state of the media through Play()
+and other methods, the media may not actually be in the
+wxMEDIASTATE\_PLAYING, for example. If you are relying on the
+media being in certain state catch the event relevant to the state.
+See \helpref{wxMediaEvent}{wxmediaevent} for the kinds of events
+that you can catch.
+
+
+\membersection{Video size}\label{videosizewxmediactrl}
+
+By default, wxMediaCtrl will scale the size of the video to the
+requested amount passed to either it's constructor or Create().
+After calling Load or performing an equivilant operation, you
+can subsequently obtain the "real" size of the video (if there
+is any) by calling GetBestSize(). Note that the actual result
+on the display will be slightly different when ShowPlayerControls
+is activated and the actual video size will be less then
+specified due to the extra controls provided by the native toolkit.
+In addition, the backend may modify GetBestSize() to include the
+size of the extra controls - so if you want the real size of the
+video just disable ShowPlayerControls().
+
+The idea with setting GetBestSize to the size of the video is
+that GetBestSize is a wxWindow-derived function that is called
+when sizers on a window recalculate. What this means is that
+if you use sizers by default the video will show in it's
+original size without any extra assistance needed from the user.
+
+
+\membersection{Player controls}\label{playercontrolswxmediactrl}
+
+Normally, when you use wxMediaCtrl it is just a window for the video to
+play in. However, some toolkits have their own media player interface.
+For example, QuickTime generally has a bar below the video with a slider.
+A special feature available to wxMediaCtrl, you can use the toolkit's interface instead of
+making your own by using the \helpref{ShowPlayerControls()}{wxmediactrlshowplayercontrols}
+function. There are several options for the flags parameter, with
+the two general flags being wxMEDIACTRLPLAYERCONTROLS\_NONE which turns off
+the native interface, and wxMEDIACTRLPLAYERCONTROLS\_DEFAULT which lets
+wxMediaCtrl decide what native controls on the interface. Be sure to review
+the caveats outlined in \helpref{Video size}{videosizewxmediactrl} before
+doing so.
+
+
\membersection{Choosing a backend}\label{choosingbackendwxmediactrl}
Generally, you should almost certainly leave this part up to
\twocolwidtha{7cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf wxMEDIABACKEND\_DIRECTSHOW}}{
-Use ActiveMovie/DirectShow. Requires wxUSE\_DIRECTSHOW to be
-enabled, requires linkage with the static library strmiids.lib,
-and is available on Windows Only.}
+Use ActiveMovie/DirectShow. Uses the native ActiveMovie
+(I.E. DirectShow) control. Default backend on Windows and
+supported by nearly all Windows versions, even some
+Windows CE versions. May display a windows media player
+logo while inactive. }
\twocolitem{{\bf wxMEDIABACKEND\_QUICKTIME}}{
-Use QuickTime. Windows and Mac Only. NOTE: On Mac Systems lower than OSX 10.2 this defaults to emulating window positioning and suffers from several bugs, including not working correctly embedded in a wxNotebook. }
-\twocolitem{{\bf wxMEDIABACKEND\_MCI}}{
-Use Media Command Interface. Windows Only. }
+Use QuickTime. Mac Only.
+WARNING: May not working correctly embedded in a wxNotebook.
+}
\twocolitem{{\bf wxMEDIABACKEND\_GSTREAMER}}{
-Use GStreamer. Unix Only. }
+Use GStreamer. Unix Only. Requires GStreamer 0.8 along
+with at the very least the xvimagesink, xoverlay, and
+gst-play modules of gstreamer to function. You need the correct
+modules to play the relavant files, for example the mad module
+to play mp3s, etc.}
+\twocolitem{{\bf wxMEDIABACKEND\_WMP10}}{
+Uses Windows Media Player 10 (Windows only) - works on mobile
+machines with Windows Media Player 10 and desktop machines with
+either Windows Media Player 9 or 10
+}
\end{twocollist}
+Note that other backends such as wxMEDIABACKEND\_MCI can now be
+found at wxCode.
+
+\membersection{Creating a backend}\label{creatingabackendwxmediactrl}
+
+Creating a backend for wxMediaCtrl is a rather simple process. Simply derive
+from wxMediaBackendCommonBase and implement the methods you want. The methods
+in wxMediaBackend correspond to those in wxMediaCtrl except for CreateControl
+which does the actual creation of the control, in cases where a custom control
+is not needed you may simply call wxControl::Create.
+
+You need to make sure to use the DECLARE\_CLASS and IMPLEMENT\_CLASS macros.
+
+The only real tricky part is that you need to make sure the file in compiled
+in, which if there are just backends in there will not happen and you may need
+to use a force link hack (see http://www.wxwidgets.org/wiki/index.php/RTTI).
+
+This is a rather simple example of how to create a backend in the
+\helpref{wxActiveXContainer}{wxactivexcontainer} documentation.

+Same as \helpref{Load}{wxmediactrlloaduriwithproxy}. Kept for wxPython compatability.
-Loads the url that \tt{location} refers to. Returns false if loading fails.
\membersection{wxMediaCtrl::Pause}\label{wxmediactrlpause}

-\func{bool}{Stop}{\void}
+\membersection{wxMediaCtrl::SetPlaybackRate}\label{wxmediactrlsetplaybackrate}
-Stops the media.
+\func{bool}{SetPlaybackRate}{\param{double }{dRate}}
-See \helpref{Operation}{operationwxmediactrl} for an overview of how stopping works.
+Sets the playback rate, or speed of the media, to that referred by \tt{dRate}.
+\tt{1.0} represents normal speed, while \tt{2.0} represents twice the normal
+speed of the media, for example. Not supported on the GStreamer (Unix) backend.
+Returns true if successful.
\membersection{wxMediaCtrl::SetVolume}\label{wxmediactrlsetvolume}
\func{bool}{SetVolume}{\param{double }{dVolume}}
-Sets the volume of the media from a 0.0 to 1.0 range.
-
+Sets the volume of the media from a 0.0 to 1.0 range to that referred
+by \tt{dVolume}. \tt{1.0} represents full volume, while \tt{0.5}
+represents half (50 percent) volume, for example. Note that this may not be
+exact due to conversion and rounding errors, although setting the volume to
+full or none is always exact. Returns true if successful.
-\membersection{wxMediaCtrl::GetVolume}\label{wxmediactrlgetvolume}
-
-\func{double}{GetVolume}{\void}
-Gets the volume of the media from a 0.0 to 1.0 range.
+\membersection{wxMediaCtrl::ShowPlayerControls}\label{wxmediactrlshowplayercontrols}
+\func{bool}{ShowPlayerControls}{\param{wxMediaCtrlPlayerControls }{flags = wxMEDIACTRLPLAYERCONTROLS\_DEFAULT}}
-\membersection{wxMediaCtrl::GetPlaybackRate}\label{wxmediactrlgetplaybackrate}
+A special feature to wxMediaCtrl. Applications using native toolkits such as
+QuickTime usually have a scrollbar, play button, and more provided to
+them by the toolkit. By default wxMediaCtrl does not do this. However, on
+the directshow and quicktime backends you can show or hide the native controls
+provided by the underlying toolkit at will using ShowPlayerControls. Simply
+calling the function with default parameters tells wxMediaCtrl to use the
+default controls provided by the toolkit. The function takes a
+\tt{wxMediaCtrlPlayerControls} enumeration as follows:
-\func{double}{GetPlaybackrate}{\void}
+\twocolwidtha{7cm}
+\begin{twocollist}\itemsep=0pt
+\twocolitem{{\bf wxMEDIACTRLPLAYERCONTROLS\_NONE}}{No controls. return wxMediaCtrl to it's default state.}
+\twocolitem{{\bf wxMEDIACTRLPLAYERCONTROLS\_STEP}}{Step controls like fastfoward, step one frame etc.}
+\twocolitem{{\bf wxMEDIACTRLPLAYERCONTROLS\_VOLUME}}{Volume controls like the speaker icon, volume slider, etc.}
+\twocolitem{{\bf wxMEDIACTRLPLAYERCONTROLS\_DEFAULT}}{Default controls for the toolkit. Currently a typedef for wxMEDIACTRLPLAYERCONTROLS\_STEP and wxMEDIACTRLPLAYERCONTROLS\_VOLUME.}
+\end{twocollist}
-Gets the playback rate of the media; for example 2.0 is double speed.
-Not implemented on MCI or GStreamer.
+For more see \helpref{Player controls}{playercontrolswxmediactrl}. Currently
+only implemented on the QuickTime and DirectShow backends. The function
+returns true on success.
-\membersection{wxMediaCtrl::SetPlaybackRate}\label{wxmediactrlsetplaybackrate}
+\membersection{wxMediaCtrl::Stop}\label{wxmediactrlstop}
-\func{bool}{SetPlaybackrate}{\param{double }{dVolume}}
+\func{bool}{Stop}{\void}
-Sets the rate that the media plays; for example 0.5 is half speed.
+Stops the media.
+See \helpref{Operation}{operationwxmediactrl} for an overview of how
+stopping works.
-\membersection{wxMediaCtrl::ShowPlayerControls}\label{wxmediactrlshowplayercontrols}
-\func{bool}{ShowPlayerControls}{\param{wxMediaCtrlPlayerControls }{flags}}
+\membersection{wxMediaCtrl::Tell}\label{wxmediactrlgetposition}
-Normally, when you use wxMediaCtrl it is just a window for the video to
-play in. However, platforms generally have their own media player interface,
-like quicktime has a bar below the video with a slider etc.. If you want that native
-interface instead of making your own use this function. There are several options
-for the flags parameter, however you can look at the mediactrl header for these.
-The two general flags are wxMEDIACTRLPLAYERCONTROLS\_NONE which turns off the
-native interface, and wxMEDIACTRLPLAYERCONTROLS\_DEFAULT which lets wxMediaCtrl
-decide what native controls on the interface.
+\func{wxFileOffset}{Tell}{\void}
+Obtains the current position in time within the movie in milliseconds.

+//-----------------Introduction----------------------------------------------
+// This is the media backend for Windows Media Player 6 and ActiveMovie,
+// as well as PocketPC 2000, Windows Media Player Mobile 7 and 8.
+//
+// We use a combination of the WMP 6 IMediaPlayer interface as well as the
+// ActiveMovie interface IActiveMovie that even exists on Windows 3. For
+// mobile systems we switch to IWMP for WMP mobile 7 and 8 and possibly
+// earlier. We just use ifdefs for differentiating between IWMP and
+// IActiveMovie/IMediaPlayer as the IWMP and IMediaPlayer are virtually
+// identical with a few minor exceptions.
+//
+// For supporting HTTP proxies and such we query the media player
+// interface (IActiveMovie/IWMP) for the INSPlay (NetShow) interface.
+//
+// The IMediaPlayer/IActiveMovie/IWMP are rather clean and straightforward
+// interfaces that are fairly simplistic.
+//
+// Docs for IMediaPlayer are at
+// http://msdn.microsoft.com/library/en-us/wmp6sdk/htm/microsoftwindowsmediaplayercontrolversion64sdk.asp

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

+
+/*
+ This is the GStreamer backend for unix. Currently we require 0.8 or
+ 0.10. Here we use the "playbin" GstElement for ease of use.
+
+ Note that now we compare state change functions to GST_STATE_FAILURE
+ now rather than GST_STATE_SUCCESS as newer gstreamer versions return
+ non-success values for returns that are otherwise successful but not
+ immediate.
+
+ Also this probably doesn't work with anything other than wxGTK at the
+ moment but with a tad bit of work it could theorectically work in
+ straight wxX11 et al.
+
+ One last note is that resuming from pausing/seeking can result
+ in erratic video playback (GStreamer-based bug, happens in totem as well)
+ - this is better in 0.10, however. One thing that might make it worse
+ here is that we don't preserve the aspect ratio of the video and stretch
+ it to the whole window.
+
+ Note that there are some things used here that could be undocumented -
+ for reference see the media player Kiss and Totem as well as some
+ other sources. There was a backend for a kde media player as well
+ that attempted thread-safety...
+
+ Then there is the issue of m_asynclock. This serves several purposes:
+ 1) It prevents the C callbacks from sending wx state change events
+ so that we don't get duplicate ones in 0.8
+ 2) It makes the sync and async handlers in 0.10 not drop any
+ messages so that while we are polling it we get the messages in
+ SyncStateChange instead of the queue.
+ 3) Keeps the pausing in Stop() synchronous
+
+ RN: Note that I've tried to follow the wxGTK conventions here as close
+ as possible. In the implementation the C Callbacks come first, then
+ the internal functions, then the public ones. Set your vi to 80
+ characters people :).
