+Screen Capture Example +====================== + +Screen Capture demonstrates how to capture a screen or window using +``QScreenCapture`` and ``QWindowCapture``. The example shows a list of screens +and windows and displays a live preview of the selected item using a +``QMediaCaptureSession`` and a ``QVideoWidget``. Capturing can be started and +stopped with a ``QPushButton``. + +Application Structure ++++++++++++++++++++++ + +The example consists of three custom classes. The UI and all screen capture +functionality is implemented in the class ``ScreenCapturePreview``. The classes +``ScreenListModel`` and ``WindowListModel`` only serve as models behind the two +``QListView`` widgets. The main function creates a ``ScreenCapturePreview`` +object, which in turn creates instances of ``QScreenCapture`` and +``QWindowCapture``, and a ``QMediaCaptureSession`` and ``QVideoWidget``, in +addition to all the UI widgets. + +The screen and window models are populated with the return values of +``QGuiApplication.screens()`` and ``QWindowCapture.capturableWindows()``, +respectively. + +When a list item is selected, it is connected to the ``QScreenCapture`` object +with ``QScreenCapture.setScreen()``, or to the ``QWindowCapture`` object with +``QWindowCapture.setWindow().`` The capture object is connected to the +``QMediaCaptureSession`` object with +``QMediaCaptureSession.setScreenCapture()`` and +``QMediaCaptureSession.setWindowCapture()``, respectively. The capture session +in turn is connected to the ``QVideoWidget`` object with +``QMediaCaptureSession.setVideoOutput()``. Thus, the capture output is +previewed in the video widget on the right hand side of the UI. + +The start/stop button calls ``QScreenCapture.start()`` and ``QScreenCapture.stop()``, +or ``QWindowCapture.start()`` and ``QWindowCapture.stop()``. + +A QMessageBox pops up if an ``errorOccurred`` signal is emitted. + +.. image. screencapture.webp + :width: 600 + :alt: screen capture example diff --git a/examples/multimedia/screencapture/doc/screencapture.webp b/examples/multimedia/screencapture/doc/screencapture.webp Binary files differnew file mode 100644 index 000000000..58ad36c7f --- /dev/null +++ b/examples/multimedia/screencapture/doc/screencapture.webp diff --git a/examples/multimedia/screencapture/main.py b/examples/multimedia/screencapture/main.py new file mode 100644 index 000000000..f445bac03 --- /dev/null +++ b/examples/multimedia/screencapture/main.py @@ -0,0 +1,20 @@ +# Copyright (C) 2023 The Qt Company Ltd. +# SPDX-License-Identifier: LicenseRef-Qt-Commercial OR BSD-3-Clause + +"""PySide6 port of the QtMultiMedia Screen Capture Example from Qt v6.x""" + +import sys + +from PySide6.QtCore import QCoreApplication +from PySide6.QtWidgets import QApplication + +from screencapturepreview import ScreenCapturePreview + + +if __name__ == "__main__": + app = QApplication(sys.argv) + QCoreApplication.setApplicationName("screencapture") + QCoreApplication.setOrganizationName("QtProject") + screen_capture_preview = ScreenCapturePreview() + screen_capture_preview.show() + sys.exit(app.exec()) diff --git a/examples/multimedia/screencapture/screencapture.pyproject b/examples/multimedia/screencapture/screencapture.pyproject new file mode 100644 index 000000000..dfec6c901 --- /dev/null +++ b/examples/multimedia/screencapture/screencapture.pyproject @@ -0,0 +1,3 @@ +{ + "files": ["main.py", "screencapturepreview.py", "screenlistmodel.py", "windowlistmodel.py"] +} diff --git a/examples/multimedia/screencapture/screencapturepreview.py b/examples/multimedia/screencapture/screencapturepreview.py new file mode 100644 index 000000000..c7e0c596a --- /dev/null +++ b/examples/multimedia/screencapture/screencapturepreview.py @@ -0,0 +1,162 @@ +# Copyright (C) 2023 The Qt Company Ltd. +# SPDX-License-Identifier: LicenseRef-Qt-Commercial OR BSD-3-Clause + +from enum import Enum, auto + +from PySide6.QtMultimediaWidgets import QVideoWidget +from PySide6.QtMultimedia import (QCapturableWindow, QMediaCaptureSession, + QScreenCapture, QWindowCapture) +from PySide6.QtWidgets import (QGridLayout, QLabel, QListView, + QMessageBox, QPushButton, QWidget) +from PySide6.QtGui import QAction, QGuiApplication +from PySide6.QtCore import QItemSelection, Qt, Slot + +from screenlistmodel import ScreenListModel +from windowlistmodel import WindowListModel + + +class SourceType(Enum): + Screen = auto() + Window = auto() + + +class ScreenCapturePreview(QWidget): + + def __init__(self, parent=None): + super().__init__(parent) + + self._source = SourceType.Screen + + self._screen_capture = QScreenCapture(self) + self._media_capture_session = QMediaCaptureSession(self) + self._video_widget = QVideoWidget(self) + self._screen_list_view = QListView(self) + self._screen_label = QLabel("Select screen to capture:", self) + self._video_widget_label = QLabel("Capture output:", self) + self._start_stop_button = QPushButton(self) + self._status_label = QLabel(self) + + self._screen_list_model = ScreenListModel(self) + + #
