我正在尝试clone
QTCpsocket
的音频流模型,但现在使用QUdpsocket
(虚拟连接),虽然看起来代码正在执行,但是,实际上它不是做这项工作,我无法获得流式音频;
主要关注点是:是否可以使用QUDpsocket启动QAudioOutput ???
然而要清楚地提到这个代码适用于TCP socket
!
代码段:
在server.h文件中
private:
QUdpSocket *socketUDP;
和.CPP文件
udpServer::udpServer(QObject *parent) : QObject(parent)
{
socketUDP = new QUdpSocket(this);
serverAddress = QHostAddress("192.168.1.8");
//socketUDP->bind(serverAddress, 1357);
socketUDP->bind(1357, QUdpSocket::ShareAddress);
socketUDP->open(QIODevice::ReadOnly);
connect(socketUDP, &QUdpSocket::readyRead, this, &udpServer::playStreamedAudio);
}
然后是playstream()方法:
void udpServer::playStreamedAudio() {
// set the QAudioFormat parameters of output audio device.
my_QAudioFormat = new QAudioFormat;
my_QAudioFormat->setSampleRate(48000);
my_QAudioFormat->setChannelCount(1);
my_QAudioFormat->setSampleSize(8);
my_QAudioFormat->setCodec("audio/pcm");
my_QAudioFormat->setByteOrder(QAudioFormat::LittleEndian);
my_QAudioFormat->setSampleType(QAudioFormat::UnSignedInt);
//
// get default audio output device
audiOutputDevice = QAudioDeviceInfo::defaultOutputDevice();
audiooutput = new QAudioOutput(audiOutputDevice,my_QAudioFormat, this);
// attach to socket!
qDebug() << "Playaing AudioStream";
socketUDP->open(QIODevice::ReadOnly);
audiooutput->start(socketUDP); // the Audio output device shall listen to server socket for audio
}
答案 0 :(得分:0)
事实证明,UDP套接字可能不适合作为QioDevices进行接口...似乎它们不是那样的,数据包最好写入文件然后进行处理。
