Detailed Description

wxMediaCtrl is a class for displaying various types of media, such as videos, audio files, natively through native codecs.

wxMediaCtrl uses native backends to render media, for example on Windows there is a ActiveMovie/DirectShow backend, and on Macintosh there is a QuickTime backend.

Rendering media

Depending upon the backend, wxMediaCtrl can render and display pretty much any kind of media that the native system can - such as an image, mpeg video, or mp3 (without license restrictions - since it relies on native system calls that may not technically have mp3 decoding available, for example, it falls outside the realm of licensing restrictions).

For general operation, all you need to do is call Load() to load the file you want to render, catch the EVT_MEDIA_LOADED event, and then call Play() to show the video/audio of the media in that event.

More complex operations are generally more heavily dependent on the capabilities of the backend. For example, QuickTime cannot set the playback rate of certain streaming media - while DirectShow is slightly more flexible in that regard.

Operation

When wxMediaCtrl plays a file, it plays until the stop position is reached (currently the end of the file/stream). Right before it hits the end of the stream, it fires off a EVT_MEDIA_STOP event to its parent window, at which point the event handler can choose to veto the event, preventing the stream from actually stopping.

Example:

// bind the media event
Bind(wxMY_ID, wxEVT_MEDIA_STOP, &MyFrame::OnMediaStop, this);
//...
void MyFrame::OnMediaStop(wxMediaEvent& evt)
{
if( userWantsToSeek )
{
m_mediactrl->Seek(m_mediactrl->Length() - 1);
evt.Veto();
}
}
void Bind(const EventTag &eventType, Functor functor, int id=wxID_ANY, int lastId=wxID_ANY, wxObject *userData=NULL)
Binds the given function, functor or method dynamically with the event.
Event wxMediaCtrl uses.
Definition: mediactrl.h:80
void Veto()
Prevents the change announced by this event from happening.
wxEventType wxEVT_MEDIA_STOP
Definition: mediactrl.h:460

When wxMediaCtrl stops, either by the EVT_MEDIA_STOP not being vetoed, or by manually calling Stop(), where it actually stops is not at the beginning, rather, but at the beginning of the stream. That is, when it stops and play is called, playback is guaranteed to start at the beginning of the media. This is because some streams are not seekable, and when stop is called on them they return to the beginning, thus wxMediaCtrl tries to keep consistent 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 wxMediaEvent for the kinds of events that you can catch.

Video size

By default, wxMediaCtrl will scale the size of the video to the requested amount passed to either its constructor or Create(). After calling wxMediaCtrl::Load or performing an equivalent operation, you can subsequently obtain the "real" size of the video (if there is any) by calling wxMediaCtrl::GetBestSize(). Note that the actual result on the display will be slightly different when wxMediaCtrl::ShowPlayerControls is activated and the actual video size will be less than specified due to the extra controls provided by the native toolkit. In addition, the backend may modify wxMediaCtrl::GetBestSize() to include the size of the extra controls - so if you want the real size of the video just disable wxMediaCtrl::ShowPlayerControls().

The idea with setting wxMediaCtrl::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 its original size without any extra assistance needed from the user.

Player controls

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 toolkits interface instead of making your own by using the ShowPlayerControls() 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 Video size before doing so.

Choosing a backend

Generally, you should almost certainly leave this part up to wxMediaCtrl - but if you need a certain backend for a particular reason, such as QuickTime for playing .mov files, all you need to do to choose a specific backend is to pass the name of the backend class to wxMediaCtrl::Create().

The following are valid backend identifiers:

  • wxMEDIABACKEND_DIRECTSHOW: Use ActiveMovie/DirectShow. Uses the native ActiveMovie (I.E. DirectShow) control. Default backend on Windows and supported by nearly all Windows versions. May display a windows media player logo while inactive.
  • wxMEDIABACKEND_QUICKTIME: Use QuickTime. Mac Only. WARNING: May not work correctly when embedded in a wxNotebook.
  • wxMEDIABACKEND_GSTREAMER, Use GStreamer. Unix Only. Requires GStreamer 0.10 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 relevant files, for example the mad module to play mp3s, etc.
  • wxMEDIABACKEND_WMP10, Use Windows Media Player 10 (Windows only). Works on systems with either Windows Media Player 9 or 10 installed.

Creating a backend

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 wxMediaCtrl::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 wxDECLARE_CLASS and wxIMPLEMENT_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 wxFORCE_LINK_MODULE usage in the mediactrl sample).

There is a rather simple example of how to create a backend in the wxActiveXContainer documentation.

Styles

This class supports the following styles:

  • wxMC_NO_AUTORESIZE:
    By default, the control will automatically adjust its size to exactly fit the size of a loaded video as soon as a video is loaded. If this flag is given, the control will not change its size automatically and it must be done manually (if desired) using Layout(). It is strongly recommended to use this flag and handle control resizing manually (note that this style is only available in wxWidgets 3.1.6, so it is only possible to do it when using this or later version).

Constructor & Destructor Documentation

◆ wxMediaCtrl() [1/2]

wxMediaCtrl::wxMediaCtrl ( )

Default constructor - you MUST call Create() before calling any other methods of wxMediaCtrl.

◆ wxMediaCtrl() [2/2]

wxMediaCtrl::wxMediaCtrl ( wxWindow parent,
wxWindowID  id,
const wxString fileName = wxEmptyString,
const wxPoint pos = wxDefaultPosition,
const wxSize size = wxDefaultSize,
long  style = 0,
const wxString szBackend = wxEmptyString,
const wxValidator validator = wxDefaultValidator,
const wxString name = "mediaCtrl" 
)

Constructor that calls Create().

You may prefer to call Create() directly to check to see if wxMediaCtrl is available on the system.

Parameters
parentparent of this control. Must not be NULL.
idid to use for events
fileNameIf not empty, the path of a file to open.
posPosition to put control at.
sizeSize to put the control at and to stretch movie to.
styleOptional styles. It is recommended to use wxMC_NO_AUTORESIZE, although it is not used by default for compatibility reasons.
szBackendName of backend you want to use, leave blank to make wxMediaCtrl figure it out.
validatorvalidator to use.
nameWindow name.

Member Function Documentation

◆ Create()

bool wxMediaCtrl::Create ( wxWindow parent,
wxWindowID  id,
const wxString fileName = wxEmptyString,
const wxPoint pos = wxDefaultPosition,
const wxSize size = wxDefaultSize,
long  style = 0,
const wxString szBackend = wxEmptyString,
const wxValidator validator = wxDefaultValidator,
const wxString name = "mediaCtrl" 
)

Creates this control.

Returns false if it can't load the media located at fileName or it can't create a backend.

If you specify a file to open via fileName and you don't specify a backend to use, wxMediaCtrl tries each of its backends until one that can render the path referred to by fileName can be found.

Parameters
parentparent of this control. Must not be NULL.
idid to use for events
fileNameIf not empty, the path of a file to open.
posPosition to put control at.
sizeSize to put the control at and to stretch movie to.
styleOptional styles. It is recommended to use wxMC_NO_AUTORESIZE, although it is not used by default for compatibility reasons.
szBackendName of backend you want to use, leave blank to make wxMediaCtrl figure it out.
validatorvalidator to use.
nameWindow name.

◆ GetBestSize()

wxSize wxMediaCtrl::GetBestSize ( ) const

Obtains the best size relative to the original/natural size of the video, if there is any.

See Video size for more information.

◆ GetPlaybackRate()

double wxMediaCtrl::GetPlaybackRate ( )

Obtains the playback rate, or speed of the media.

1.0 represents normal speed, while 2.0 represents twice the normal speed of the media, for example. Not supported on the GStreamer (Unix) backend.

Returns
zero on failure.

◆ GetState()

wxMediaState wxMediaCtrl::GetState ( )

Obtains the state the playback of the media is in.

wxMEDIASTATE_STOPPED The media has stopped.
wxMEDIASTATE_PAUSED The media is paused.
wxMEDIASTATE_PLAYING The media is currently playing.

◆ GetVolume()

double wxMediaCtrl::GetVolume ( )

Gets the volume of the media from a 0.0 to 1.0 range.

Note
Due to rounding and other errors the value returned may not be the exact value sent to SetVolume().

◆ Length()

wxFileOffset wxMediaCtrl::Length ( )

Obtains the length - the total amount of time the media has in milliseconds.

◆ Load() [1/3]

bool wxMediaCtrl::Load ( const wxString fileName)

Loads the file that fileName refers to.

Returns false if loading fails.

◆ Load() [2/3]

bool wxMediaCtrl::Load ( const wxURI uri)

Loads the location that uri refers to.

Note that this is very implementation-dependent, although HTTP URI/URLs are generally supported, for example. Returns false if loading fails.

◆ Load() [3/3]

bool wxMediaCtrl::Load ( const wxURI uri,
const wxURI proxy 
)

Loads the location that uri refers to with the proxy proxy.

Not implemented on most backends so it should be called with caution. Returns false if loading fails.

◆ LoadURI()

bool wxMediaCtrl::LoadURI ( const wxString uri)

Same as Load(const wxURI& uri).

Kept for wxPython compatibility.

◆ LoadURIWithProxy()

bool wxMediaCtrl::LoadURIWithProxy ( const wxString uri,
const wxString proxy 
)

Same as Load(const wxURI& uri, const wxURI& proxy).

Kept for wxPython compatibility.

◆ Pause()

bool wxMediaCtrl::Pause ( )

Pauses playback of the media.

◆ Play()

bool wxMediaCtrl::Play ( )

Resumes playback of the media.

◆ Seek()

wxFileOffset wxMediaCtrl::Seek ( wxFileOffset  where,
wxSeekMode  mode = wxFromStart 
)

Seeks to a position within the media.

Todo:
Document the wxSeekMode parameter mode, and perhaps also the wxFileOffset and wxSeekMode themselves.

◆ SetPlaybackRate()

bool wxMediaCtrl::SetPlaybackRate ( double  dRate)

Sets the playback rate, or speed of the media, to that referred by dRate.

1.0 represents normal speed, while 2.0 represents twice the normal speed of the media, for example. Not supported on the GStreamer (Unix) backend. Returns true if successful.

◆ SetVolume()

bool wxMediaCtrl::SetVolume ( double  dVolume)

Sets the volume of the media from a 0.0 to 1.0 range to that referred by dVolume.

1.0 represents full volume, while 0.5 represents half (50 percent) volume, for example.

Note
The volume 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.

◆ ShowPlayerControls()

bool wxMediaCtrl::ShowPlayerControls ( wxMediaCtrlPlayerControls  flags = wxMEDIACTRLPLAYERCONTROLS_DEFAULT)

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 wxMediaCtrlPlayerControls enumeration, please see available show modes there.

For more info see Player controls.

Currently only implemented on the QuickTime and DirectShow backends. The function returns true on success.

◆ Stop()

bool wxMediaCtrl::Stop ( )

Stops the media.

See Operation for an overview of how stopping works.

◆ Tell()

wxFileOffset wxMediaCtrl::Tell ( )

Obtains the current position in time within the media in milliseconds.
