我需要用 OpenAL 播放流声音。这是我的代码,但它不起作用。我需要做什么?
device = alcOpenDevice(NULL);
//
ofstream file;
file.open("TESTSPEAKER", std::ios_base::binary);
context = alcCreateContext(device, NULL);
alcMakeContextCurrent(context);
// alGetError();
char *alBuffer;
ALenum alFormatBuffer;
ALsizei alFreqBuffer;
long alBufferLen;
ALboolean alLoop;
unsigned int alSource;
unsigned int alSampleSet;
boost::array <char, 882> buf;
while (!ExitKey)
{
boost::system::error_code error;
size_t len = VoiceSocket->read_some(boost::asio::buffer(buf), error);
if (len==0)
{
continue;
}
file.write(buf.data(), 882);
alGenSources(1, &alSource);
alGenBuffers(1, &alSampleSet);
alBufferData(alSource, AL_FORMAT_MONO16, buf.data(), buf.size(), 44100);
alSourcei(alSource, AL_BUFFER, alSampleSet);
//
//alSourcei(alSource, AL_LOOPING, alSampleSet);
alSourcePlay(alSource);
//alSourcePlay(alSource);
}
VoiceSocket->close();
file.close();
如果我看到我的文件(“TESTSPEAKER”),我会看我的声音。所以我在网络上正确地传递它。但是我怎样才能用 openal 播放这个声音呢?
