<![CDATA[How to open local ipcamera]]>vmware win10 qt6.7

QMediaPlayer *player = new QMediaPlayer();
player->setVideoOutput(ui->videooutput);
player->setSource(QUrl("rtsp://guest:335577@192.168.55.100"));
player->play();

Can open ipcamera but it has 6 seconds delay

python opencv, the delay is 1 second

 const QList<QCameraDevice> camera = QMediaDevices::videoInputs();

Can not find ipcamera, just can find usb camera

Your URL does not include port number and your code uses the default port number.

I am not familiar with FFmpeg. However, If you switch to use gstreamer, the delay might be 2s.

But yes, one should check if the port is correct.

However, port numbers are 16 bit. The highest port number that can be assigned is 65535. Your port number is way beyond that. This cannot work.
