在C#中,使用Real-Time Transport Protocol (RTP) 和 Real-Time Messaging Protocol (RTCP) 进行音视频传输时,需要设置定时器以处理超时和重传等操作
以下是一个示例代码,展示了如何在C#中设置这些定时器:
using System;
using System.Timers;
class RtpTimer
{
private Timer t1, t2, t3, t4, t5;
public RtpTimer()
{
t1 = new Timer(5000); // 5 seconds
t1.Elapsed += new ElapsedEventHandler(OnT1Elapsed);
t2 = new Timer(100); // 100 milliseconds
t2.Elapsed += new ElapsedEventHandler(OnT2Elapsed);
t3 = new Timer(200); // 200 milliseconds
t3.Elapsed += new ElapsedEventHandler(OnT3Elapsed);
t4 = new Timer(200); // 200 milliseconds
t4.Elapsed += new ElapsedEventHandler(OnT4Elapsed);
t5 = new Timer(400); // 400 milliseconds
t5.Elapsed += new ElapsedEventHandler(OnT5Elapsed);
}
public void StartTimers()
{
t1.Start();
t2.Start();
t3.Start();
t4.Start();
t5.Start();
}
public void StopTimers()
{
t1.Stop();
t2.Stop();
t3.Stop();
t4.Stop();
t5.Stop();
}
private void OnT1Elapsed(object sender, ElapsedEventArgs e)
{
// Handle RTCP report interval
}
private void OnT2Elapsed(object sender, ElapsedEventArgs e)
{
// Handle one-way network delay
}
private void OnT3Elapsed(object sender, ElapsedEventArgs e)
{
// Handle two-way network delay
}
private void OnT4Elapsed(object sender, ElapsedEventArgs e)
{
// Handle RTP packet loss detection
}
private void OnT5Elapsed(object sender, ElapsedEventArgs e)
{
// Handle RTP packet retransmission
}
}
请注意,这个示例仅用于说明如何设置定时器。实际上,您需要根据您的应用程序需求来处理定时器事件。
