, i find isCaptureModeSupported(QCamera::CaptureVideo) is false, you are right，I do use Windows platforms, thank you ,It seems that I can only use other methods.

Hi
Can you try to qDebug() << camera->isCaptureModeSupported(QCamera::CaptureVideo);.

I got this feeling recording is not supported.

"Video recording is currently not supported. "

Hi
It looks ok, but you should hook up the error handling signals to catch any errors.
void QMediaRecorder::error(QMediaRecorder::Error error)

@mrjj sorry sir, I think I may let you misunderstand，i do this don't use qt example,all codes show as following;

viewFinder = new QCameraViewfinder();
    camera = new QCamera;
    recorder = new QMediaRecorder(camera);
    camera->setCaptureMode(QCamera::CaptureVideo);
    camera->setViewfinder(viewFinder);
    camera->start();
    viewFinder->show();
    QAudioEncoderSettings audioSettings;
    audioSettings.setCodec("audio/amr");
    audioSettings.setQuality(QMultimedia::HighQuality);
    recorder->setAudioSettings(audioSettings);
    QVideoEncoderSettings videoSettings;
    videoSettings.setCodec("video/mpeg2");
    videoSettings.setResolution(640, 480);
    recorder->setVideoSettings(videoSettings);
    recorder->setOutputLocation(QUrl::fromLocalFile("1.mp4"));
    recorder->record();

i want these codes will have the function which can save the video from camera,i mean “Are there any missing steps”

Hi
That seems like a deplyment folder and not so much a build folder.
However, i assume you mean when you just run it then.
Maybe the tab is grey as it cant save the video.
You should check the sample code under what condition, it won't allow the tab.
You could also try with path in setOutputLocation

@Flame said in how can i find the file saved by Qmediarecorder:

setOutputLocation

Try to look in your build folder.
