使用OpenAL中的捕获数据

Question

我想制作一个简单的语音聊天程序并使用OpenAL。一方面我捕获语音并通过互联网发送（使用Boost.Asio），所以在另一方面我只需要播放捕获的声音。但我的问题是，我设法捕获语音说，5秒，但在另一边（我的意思是另一个客户端，计算机）播放5秒语音只是第一秒而不是整个数据。我不明白我的代码有什么问题，请帮助我，你的任何建议对我来说都非常重要。 提前谢谢!!!

captureDev = alcCaptureOpenDevice(NULL, 8000, AL_FORMAT_MONO16, 800);

// ... //...

lastTime = currentTime;
    // Capture (roughly) five seconds of audio 

    ALubyte           captureBuffer[104857];
    ALubyte           *captureBufPtr;
        alcCaptureStart(captureDev);
        samplesCaptured = 0;
        captureBufPtr = captureBuffer;
        while (currentTime < (lastTime + 5))
        {
            // Get the number of samples available 
            alcGetIntegerv(captureDev, ALC_CAPTURE_SAMPLES, 1, &samplesAvailable);

            // Copy the samples to our capture buffer 
            if (samplesAvailable > 0)
            {
                alcCaptureSamples(captureDev, captureBufPtr, samplesAvailable);
                samplesCaptured += samplesAvailable;
                printf("Captured %d samples (adding %d)\r", samplesCaptured,
                    samplesAvailable);
                fflush(stdout);

                // Advance the buffer (two bytes per sample * number of samples) 
                captureBufPtr += samplesAvailable * 2;
            }

            // Wait for a bit 
            std::this_thread::sleep_for(std::chrono::seconds(1));

            // Update the clock 
            currentTime = time(NULL);
        }

所以我发送捕获的数据 captureBuffer 与 samplesCaptured ，另一方面（客户端）我收到它们并想玩。

// Generate an OpenAL buffer for the captured data 
    alGenBuffers(1, &buffer);
    alGenSources(1, &source);
    alBufferData(buffer, AL_FORMAT_MONO16, captureBuffer, samplesCaptured * 2, 8000);
    alSourcei(source, AL_BUFFER, buffer);
    alSourcePlay(source);

    // Wait for the source to stop playing 
    playState = AL_PLAYING;
    while (playState == AL_PLAYING)
    {
        printf("  source %d is playing...\r", source);
        fflush(stdout);
        alGetSourcei(source, AL_SOURCE_STATE, &playState);
        std::this_thread::sleep_for(std::chrono::seconds(1));
    }

正如我上面所说，它不是整个数据。
