I have developed a simple application (using QT) to record the video from laptop's camera. I've used the following classes:
QCamera
QCameraInfo
QMediaRecorder
QUrl
QCameraViewfinder
QCameraImageCapture
It works and it can show the video and I am able to still an image but, when I try to record a video using "QMediaRecorder" I face the following error:
Error message:
(videoD:19102): GLib-GObject-CRITICAL **: 13:01:07.717: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
The operation system is Ubuntu 18 and I have installed libpulse-dev.
