I have a problem displaying a screenshot of a youtube video.
in Pyside, I turned on the flash function using the command below to play videos in the Pyside browser
s.setAttribute(QWebSettings.PluginsEnabled, True) s.setAttribute(QWebSettings.JavascriptEnabled, True)
now my script can open the embedded website and play the video, but when I tried to capture a screenshot, it shows a black screen on the embedded video.
Script:
#!/usr/bin/env python #-*- coding:utf-8 -*- from PySide.QtCore import Qt, QUrl, QTimer, Slot from PySide.QtGui import QApplication, QImage, QPainter from PySide.QtWebKit import QWebView, QWebPage, QWebSettings from PySide.QtNetwork import QNetworkRequest, QNetworkReply import time, sys class Render(QWebView): def __init__(self, url, filename, image_crop, translate_page, parent=None): super(Render, self).__init__(parent) self.image_crop = image_crop self.fileName = time.strftime("%Y%m%d%H%M%S",time.localtime()) +"_test.jpg" self.finished = False # Settings s = self.page().settings() s.setAttribute(QWebSettings.AutoLoadImages, True) s.setAttribute(QWebSettings.PluginsEnabled, True) s.setAttribute(QWebSettings.JavascriptEnabled, True) s.setAttribute(QWebSettings.JavaEnabled, False) s.setAttribute(QWebSettings.JavascriptCanOpenWindows, False) s.setAttribute(QWebSettings.DeveloperExtrasEnabled, True) #self.page().mainFrame().setScrollBarPolicy(Qt.Horizontal, Qt.ScrollBarAlwaysOff) self.page().mainFrame().setScrollBarPolicy(Qt.Vertical, Qt.ScrollBarAlwaysOff) self.timerScreen = QTimer() self.timerScreen.setInterval(10000) self.timerScreen.setSingleShot(True) self.timerScreen.timeout.connect(self.takeScreenshot) self.loadFinished.connect(self.timerScreen.start) self.load(QUrl(url)) @Slot(QNetworkReply) def takeScreenshot(self): [x,y,width,height] = self.image_crop frame = self.page().mainFrame() size = frame.contentsSize() size.setWidth(1000) size.setHeight(2000) self.page().setViewportSize(size) image = QImage(self.page().viewportSize(), QImage.Format_ARGB32) painter = QPainter(image) frame.render(painter) painter.end() image1 = image.copy(x,y,width,height) image1.save(self.fileName) self.finished = True def run(url, filename, image_crop, translate_page): app=QApplication.instance() if not app: app = QApplication(sys.argv) app.setApplicationName('myWindow') r = Render(url, filename, image_crop, translate_page) r.show() while not r.finished: app.processEvents() time.sleep(0.01) return r.filepath Screenshot_Name = run("http://www.youtube.com/watch?v=frrvOnEZO3k", 'www.youtube.com', [0,0,1000,1000], translate_page='NO') print Screenshot_Name
