Description
Hello,
I'm experiencing what appears to be a bug in QVideoWidget. When I resize the window containing the video the image becomes stretched. During the resize, while the mouse is pressed, the video frame flickers between the stretched state and a state where its aspect ratio is maintained, and stays stretched when I release the mouse (see attached image).
A basic version of the widget I'm using to replicate the issue is shown below (using PySide2):
class Editor(QWidget): def __init__(self, video_filename, parent=None): super().__init__(parent) main_layout = QVBoxLayout() video = QVideoWidget() video.setAspectRatioMode(Qt.KeepAspectRatio) main_layout.addWidget(video) self.player = QMediaPlayer() self.player.setMedia(QUrl.fromLocalFile(video_filename)) self.player.setVideoOutput(video) self.setLayout(main_layout) self.player.play()
The system I'm running this on is Ubuntu18.04 with the X11 window system and GStreamer1.15.5
