Frank Shearar SIP 组件

我正在查看 Frank Shearar 的演示程序，但无法构建该演示程序。我修复了所有对“丢失文件”的引用，我试图修复的最后一个错误与类中接口的差异以及它们现在的使用方式有关...

Self.CalleeMedia := TIdSDPMultimediaSession.Create(Self.Profile);

Self.CalleeMedia := TIdSDPMultimediaSession.Create(Self.Profile, ???, ???);

我知道接口现在看起来像... .

constructor TIdSDPMultimediaSession.Create(Profile: TIdRTPProfile; 
  Factory: TIdSdpMediaStreamFactory; ExecutionContext: TIdTimerQueue);

我可以添加...

x := TIdSdpMediaStreamFactory.Create;
y := TIdTimerQueue.Create;

并传递这些吗？或者在这两种情况下都为零。在构建演示程序时，我在其他一些地方也遇到了类似的错误。我是否只需要创建所需的其他对象？如果不是，还需要采取哪些额外步骤？任何帮助我开始的帮助都会很棒。

谢谢，

I am looking at the demo program by Frank Shearar and cannot build the demo program. I fixed up all the references to "missing files" and the last errors that I am trying to fix are related to differences in the interface in classes and how they are used now...

Self.CalleeMedia := TIdSDPMultimediaSession.Create(Self.Profile);

Self.CalleeMedia := TIdSDPMultimediaSession.Create(Self.Profile, ???, ???);

I know the interface now looks like....

constructor TIdSDPMultimediaSession.Create(Profile: TIdRTPProfile; 
  Factory: TIdSdpMediaStreamFactory; ExecutionContext: TIdTimerQueue);

and I could just add...

x := TIdSdpMediaStreamFactory.Create;
y := TIdTimerQueue.Create;

and pass these in? Or pas nil in both cases. There are a few other places where I get similar errors when building the demo program. Do I just need to create other objects that are required? If not, what additional steps are needed? Any assistance to get me started would be great.

Thanks,

我怀疑我只是忘记更新演示以符合 SDP API 的接口！

在实例化 TIdSDPMultimediaSession 之前创建 TIdSdpMediaStreamFactory 和 TIdTimerQueue。

特别是，看看测试用例是如何设置的，在 test\TestIdSdp.pas 中：

procedure TestTIdSDPMultimediaSession.SetUp;
begin
  inherited SetUp;

  Self.Factory     := TMockMediaStreamFactory.Create;
  Self.Profile     := TIdAudioVisualProfile.Create;
  Self.Timer       := TIdThreadedTimerQueue.Create(false);
  Self.MS          := TIdSDPMultimediaSession.Create(Self.Profile, Self.Factory, Self.Timer);
  Self.PortBlocker := TIdMockRTPPeer.Create;

  // We only instantiate Server so that we know that GStack points to an
  // instantiated stack.
  Self.Server := TIdUdpServer.Create(nil);
end;

I suspect I simply forgot to update the demo in line with the SDP API's interface!

Create the TIdSdpMediaStreamFactory and TIdTimerQueue before instantiating the TIdSDPMultimediaSession.

In particular, take a look at how the test case is set up, in test\TestIdSdp.pas:

procedure TestTIdSDPMultimediaSession.SetUp;
begin
  inherited SetUp;

  Self.Factory     := TMockMediaStreamFactory.Create;
  Self.Profile     := TIdAudioVisualProfile.Create;
  Self.Timer       := TIdThreadedTimerQueue.Create(false);
  Self.MS          := TIdSDPMultimediaSession.Create(Self.Profile, Self.Factory, Self.Timer);
  Self.PortBlocker := TIdMockRTPPeer.Create;

  // We only instantiate Server so that we know that GStack points to an
  // instantiated stack.
  Self.Server := TIdUdpServer.Create(nil);
end;
