1. Add VisioForge.Controls.UI.WinForms.VolumeMeterPro.VolumeMeter control to the form. For stereo, you can add second control.
2. Set Audio_VUMeter_Pro_Enabled property to true before the Start/Play method call.
3. Add OnAudioVUMeterProVolume event handle in your MediaPlayer or VideoCapture control instance.
private void VideoCapture1_OnAudioVUMeterProVolume(object sender, AudioLevelEventArgs e)
{
volumeMeter1.Amplitude = e.ChannelLevelsDb[0];
if (e.ChannelLevelsDb.Length > 1)
{
volumeMeter2.Amplitude = e.ChannelLevelsDb[1];
}
}
1. Add VisioForge.Controls.UI.WinForms.VolumeMeterPro.WaveformPainter control to the form. For stereo, you can add second control.
2. Set Audio_VUMeter_Pro_Enabled property to true before the Start/Play method call.
3. Add OnAudioVUMeterProVolume event handle in your MediaPlayer or VideoCapture control instance.
private void VideoCapture1_OnAudioVUMeterProVolume(object sender, AudioLevelEventArgs e)
{
waveformPainter1.AddMax(e.ChannelLevelsDb[0]);
if (e.ChannelLevelsDb.Length > 1)
{
waveformPainter2.AddMax(e.ChannelLevelsDb[1]);
}
}
1. Add VisioForge.Controls.UI.WPF.VolumeMeterPro.VolumeMeter control to the form. For stereo, you can add second control.
2. Set Audio_VUMeter_Pro_Enabled property to true before the Start/Play method call.
VideoCapture1.Audio_VUMeter_Pro_Enabled = true; volumeMeter1.Start(); volumeMeter2.Start();
private delegate void AudioVUMeterProVolumeDelegate(AudioLevelEventArgs e);
private void AudioVUMeterProVolumeDelegateMethod(AudioLevelEventArgs e)
{
volumeMeter1.Amplitude = e.ChannelLevelsDb[0];
volumeMeter1.Update();

{
volumeMeter2.Amplitude = e.ChannelLevelsDb[1];
volumeMeter2.Update();
}
}
private void VideoCapture1_OnAudioVUMeterProVolume(object sender, AudioLevelEventArgs e)
{
Dispatcher.BeginInvoke(new AudioVUMeterProVolumeDelegate(AudioVUMeterProVolumeDelegateMethod), e);
}
4. After stopping playback, stop volume meters
volumeMeter1.Stop(); volumeMeter1.Clear(); volumeMeter2.Stop(); volumeMeter2.Clear();
