GAMBAS BOOK 3.19.3

The class implements a fully functional media player. The MediaPlayer class inherits MediaPipeline. This makes MediaPipeline the base class for the MediaPlayer control. Note that the class also has all the inherited properties, methods and events specified in the documentation! The class works like a read/write array and can be created.

How to create a new MediaPlayer:

Dim hMediaPlayer As MediaPlayer
hMediaPlayer=New MediaPlayer ([Parent As MediaContainer,Type As String,Polling As Integer])[As "EventName"]

Notes on the three optional parameters:

• Parent (type MediaContainer): Sets the parent element of the control.
• Type (type String): Sets the type of the MediaControl used.
• Polling (type Integer): Sets the polling frequency of the message bus.

The MediaPlayer class has these specific properties:

The virtual object .MediaPlayer.Balance.Channel implements a video balance channel with the properties Min (default: -1000), Max (default: +1000), Name and Value. You can explore the names of the individual balance channels, for example, with the following source code section:

For i = 0 To MPlayer.Balance.Count - 1
    Print "MPlayer-BalanceChannel: "; i, MPlayer.Balance[i].Name
Next

Output in the IDE console:

MPlayer-BalanceChannel: 0       CONTRAST
MPlayer-BalanceChannel: 1       BRIGHTNESS
MPlayer-BalanceChannel: 2       HUE
MPlayer-BalanceChannel: 3       SATURATION

The following assignment allows you to manipulate the video balance channel for the contrast, for example:

Private SliderBalanceContrast As New Slider
MediaPlayer.Balance[0].Value = SliderBalanceContrast.Value
