用VB6.0编写拉取rtmp流的源代码

我可以回答这个问题。以下是一个VB6.0编写的拉取rtmp流的源代码示例：

Private Sub Command1_Click()
Dim rtmp As New CRtmp
rtmp.Connect "rtmp://example.com/live/stream"
rtmp.Play
End Sub

Class CRtmp
Private Declare Function rtmp_Connect Lib "librtmp.dll" Alias "_rtmp_Connect@8" (ByVal url As String) As Long
Private Declare Function rtmp_Play Lib "librtmp.dll" Alias "_rtmp_Play@4" (ByVal handle As Long) As Long
Private Declare Function rtmp_Close Lib "librtmp.dll" Alias "_rtmp_Close@4" (ByVal handle As Long) As Long
Private handle As Long

Public Sub Connect(ByVal url As String)
handle = rtmp_Connect(url)
End Sub

Public Sub Play()
rtmp_Play handle
End Sub

Private Sub Class_Terminate()
rtmp_Close handle
End Sub
End Class

注意：这只是一个示例代码，实际使用时需要根据具体情况进行修改。
