用的就是它给的帮助文档里的程序，报错是 error C2660: 'StartPlayingFileTX' : function does not take 5 parameters error C2660: 'StartPlayingFileRX' : function does not take 6 parameters error C2660: 'StartPlayingFileRX' : function does not take 6 parameters 参数竟有问题？不知什么原因？大家帮忙看看啊这个是帮助文档里的程序思路 Sample Code The following sections describes through an example how to use the Media Term component. Here are the basic steps Initialize COM (CoInitializeEx) Instantiate the Media Term Component and get the ICCNMediaTerm COM interface (Say the variable is CCNMediaTerm) using CoCreateInstance Initialize the WINRTP · Initialize(); Transmit Side · Set the startup parameters for transmit: Use G.711 Ulaw Codec, 30ms packet size, No silence suppression. Transmit to localhost (127.0.0.1) to port 21243 o SetAudioCodecTX(4, 30, 0, 0, 1, 0); o SetAudioDestination(“127.0.0.1”, 21243); · Start transmission using the default audio capture device o StartTX(-1); · Mix the file “foo.wav” along with the transmitted stream. Play the file once. o StartPlayingFileTX(“foo.wav”, 1, 0, 0, &sendFileCookie) · Set the volume of the “foo.wav” file to 50% o SetFilePlayVolume(sendFileCookie, 50) · Change the codec from G.711 Ulaw to G.723 at 5.3kbps and turn on silence suppression o SetAudioCodecTX(9, 30, 0, 1, 1, 0) · Stop Transmitting (everything, including voice and files) o StopTX() Receive Side · Set the startup parameters for receive: Use G.711 Ulaw Codec, 30ms packet size. Receiving from local port 8000 o SetAudioCodecRX(4, 30, 0, 0); o SetAudioReceivePort(8000); · Start receive side using the default audio playback device o StartRX(-1); · Mix the file “foo.wav” along with the received stream. Play the file continuously in a loop. Also play another file “foobar.wav” just once. Mix both files along with the received audio o StartPlayingFileRX(“foo.wav”, 0, 0, 0, -1, &receiveFileCookie1); o StartPlayingFileRX(“foobar.wav”, 1, 0, 0. –1, &receiveFileCookie2); · Set the volume of the “foobar.wav” file to 25% o SetFilePlayVolume(receiveFileCookie2, 25) · Stop playing the “foo.wav” file that was playing in a loop o StopPlayingFileRX(receiveFileCookie1); · Change the codec from G.711 Ulaw to G.729 (30ms packet size), and also change the port to receive audio from 8000 to 9999 o SetAudioCodecRX(11, 30, 0, 0) o SetAudioReceivePort(9999) · Stop receiving (everything, including voice and files). This method releases the speaker o StopRX() Uninitialize the WINRTP and release all resources Uninitialize() Uninitialize COM if needed using CoUninitialize
