Examples
The following example changes AllowedDirection and applies it to an AudioVideoFlow.
C# Modifying AudioChannelTemplate properties.
AudioVideoFlowTemplate templateToApply = new AudioVideoFlowTemplate(audioVideoFlow);
AudioChannelTemplate audioChannelTemplate = (AudioChannelTemplate)templateToApply.Audio.GetChannels()[ChannelLabel.AudioMono];
audioChannelTemplate.AllowedDirection = MediaChannelDirection.SendOnly;
audioChannelTemplate.SendDirectionSamplingRate = AudioSamplingRate.EightKhz;
// ApplyChanges
audioVideoFlow.BeginApplyChanges(
templateToApply,
new AsyncCallback(delegate(IAsyncResult result)
{
try
{
audioVideoFlow.EndApplyChanges(result);
}
catch (RealTimeException e)
{
// handle exception
throw e;
}
// ApplyChanges is done, verify changes result..
AudioChannel audioChannel = audioVideoFlow.Audio.GetChannels()[ChannelLabel.AudioMono];
if (audioChannel.Direction == MediaChannelDirection.SendOnly &&
audioChannel.SendDirectionSamplingRate == AudioSamplingRate.EightKhz)
{
// remote side accepted changes as they were
}
else
{
// remote side accepted changes but filtered them more.
}
}),
this);
