// ---------------------------------------------------------------------------
// video size/position setup
// ---------------------------------------------------------------------------

// madVR supports "IVideoWindow" and "IBasicVideo". Both need to be used in
// a specific way to achieve the best results. You should always use
// IVideoWindow::SetWindowPosition() to make madVR cover the whole rendering
// client area of your media player's window.

// Some media players offer different zoom modes. Here's what madVR supports:
// 1) touchInside:
//    The video is zoomed, maintaining the correct AR (aspect ratio), in such
//    a way that the video is displayed as large as possible, without losing
//    any image content. There may be black bars, either left/right, or
//    top/bottom.
// 2) touchOutside:
//    The video is zoomed, maintaining the correct AR, in such a way that the
//    video is displayed as large as possible, without any black bars. Some
//    image content may be cut off.
// 3) stretch:
//    The video is zoomed and stretched to perfectly fill the rendering
//    client area. The AR might be distorted, but there will be no black bars.
// 4) 100% (or 50% or 200% or some other percent number):
//    The video is displayed at 100% (or 50% or ...) of the original size,
//    maintaining the correct AR.

// Some media players offers different X/Y video alignments/positions. Here's
// what madVR supports:
// 1) left/top:
//    The video is positioned left/top aligned.
// 2) center:
//    The video is rendered in centered positioned.
// 3) right/bottom:
//    The video is positioned right/bottom aligned.

// In addition to these zoom and alignment modes, some media players allow
// further fine tuning the zoom/position by increasing/decreasing the zoom
// factor, or by offsetting the image position. madVR supports that as well,
// of course.

// When using madVR, you have 3 options to setup zoom modes and positions:
// a) You can calculate a specific target rect for the video yourself and
//    tell madVR about it by calling IBasicVideo::SetDestinationPosition().
// b) You can use the "IMadVRCommand" interface (described in detail below)
//    to tell madVR which zoom & alignment modes to use.
// c) Don't do anything. In that case madVR will default to "touchInside"
//    and "center" zoom/alignment modes.

// In case of a) madVR will actually try to "understand" your target rect
// and map it internally to one of the supported zoom modes. This is done
// because madVR has complex options for the user to decide how zooming
// should be performed exactly. In order to process these options, madVR
// may have to dynamically adjust the target rect to things like screen
// masking, or detected hard coded subtitles in the black bars.

// Usually madVR's interpretation of your target rect works just fine. But
// there are situations when madVR has no way to know which zoom mode is really
// active in the media player. E.g. playing a 720p movie in a 720p window
// would match any of the available zoom or alignment modes. Because of that
// it is usually recommended to use options b) or c) described above.
// If you set a specific zoom mode (option b), madVR will ignore any calls
// to IBasicVideo::SetDestinationPosition().

// ---------------------------------------------------------------------------
// IMadVROsdServices
// ---------------------------------------------------------------------------

// this interface allows you to draw your own graphical OSD
// your OSD will work in both windowed + exclusive mode
// there are 2 different ways to draw your OSD:

// (1) using bitmaps
// you can create multiple OSD elements
// each OSD element gets a name, a bitmap and a position
// the bitmap must be 24bit or 32bit RGB(A)
// for transparency you can use a color key or an 8bit alpha channel

// (2) using render callbacks
// you can provide madVR with callbacks
// these callbacks are then called during rendering
// one callback will be called the rendering target was cleared
// another callback will be called after rendering was fully completed
// in your callbacks you can modify the render target any way you like

// ---------------------------------------------------------------------------

// when using the (1) bitmaps method, you can register a mouse callback
// this callback will be called whenever a mouse event occurs
// mouse pos (0, 0) is the left top corner of the OSD bitmap element
// return "true" if your callback has handled the mouse message and
// if you want the mouse message to be "eaten" (instead of passed on)

// CAUTION: This interface is obsolete. Use IMadVRInfo instead:
// IMadVRInfo::InfoGetBoolean("ExclusiveModeActive")
// IMadVRInfo::InfoGetBoolean("MadVRSeekbarEnabled")

// this interface allows you to ask...
// ... whether madVR is currently in exclusive mode
// ... whether the madVR exclusive mode seek bar is currently enabled

// If madVR is in fullscreen exclusive mode, you should be careful with
// which GUI you show, because showing any window based GUI will make madVR
// automatically switch back to windowed mode. That's ok if that's what you
// really want, just be aware of that. A good alternative is to use the
// graphical or text base OSD interfaces (see above). Using them instead of
// a window based GUI means that madVR can stay in exclusive mode all the
// time.

// Since madVR has its own seek bar (which is only shown in fullscreen
// exclusive mode, though), before showing your own seek bar you should
// check whether madVR is in fullscreen exclusive mode and whether the
// user has enabled madVR's own seek bar. If so, you should probably not
// show your own seek bar. If the user, however, has the madVR seek bar
// disabled, you should still show your own seek bar, because otherwise
// the user will have no way to seek at all.
