Audio Tracks

To get a full list of audio tracks use the Discover class.

Discover file = new Discover(@"/path/to/some/video.avi", @"\path\to\mplayer.exe");
file.Execute();
List<int> tracks = file.AudioList;

This will give you a list of audio track ids that can be used with the MPlayer class function SwitchAudioTrack. The example below will get a list of audio tracks in a file. Start playing the file and if the number of audio tracks is greater than 1 it will switch to the second track.

C Sharp

using System;
using LibMPlayerCommon;

class MainClass
{	
	public static void Main (string[] args)
	{
		int handle = (int)System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle;
		
		Discover file = new Discover(@"/path/to/some/video.avi", @"\path\to\mplayer.exe");
                file.Execute();
		List<int> tracks = file.AudioList;

		MPlayer _play;
		_play = new MPlayer(handle, MplayerBackends.SDL,
			@"\path\to\mplayer.exe");
		
		_play.Play(@"/path/to/some/video.avi");
		if (tracks.Count > 1)
		{
                    _play.SwitchAudioTrack(tracks[1]);
		}

		Console.WriteLine ("Press enter to exit...");
		System.Console.ReadLine();
	}
}

VB

Imports LibMPlayerCommon

Class MainClass
	Public Shared Sub Main(args As String())
		Dim handle As Integer = CInt(System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle)

		Dim file As New Discover("/path/to/some/video.avi", "\path\to\mplayer.exe")
                file.Execute()

		Dim _play As MPlayer
		_play = New MPlayer(handle, MplayerBackends.SDL, "\path\to\mplayer.exe")

		_play.Play("/path/to/some/video.avi")
		If tracks.Count > 1 Then
			_play.SwitchAudioTrack(tracks(1))
		End If

		Console.WriteLine("Press enter to exit...")
		System.Console.ReadLine()
	End Sub
