Unsolved [desktop] Video recording is not working
-
Hello there.
I'd like to video recording with usb camera on qml application for linux.
I use "QML Camera Example declarative-camera".
https://doc.qt.io/qt-5/qtmultimedia-multimedia-declarative-camera-example.htmlCameraButton { text: "Record" onClicked: camera.videoRecorder.record() }
when I clicked "Record" button then I can see error message on Qt creator's application output window.
CameraBin error: "Device '/dev/video0' is busy"
CameraBin error: "Internal data flow error."
Next I clicked "Stop" button then clicked "Record" button again.
I can see it.
CameraBin warning: "Can't record audio fast enough"
I don't know how to do but sometome I can see it.
** (declarative-camera:439): CRITICAL **: No headers or buffers on pad muxer:video_941036892I wonder if I have to change setting on linux or something?
Thanks for any advice.
