I have created a simple webkit program using python. The program loads a little web browser. Everything appears to work correctly, except webcam access. If I load a website that attempts to access the webcam (with JS getUserMedia() function) it simply does not work. (I do have a webcam attached)
Please someone help me get a browser in python working using webkit (or qtwebengine) that can access the webcam.
Here is the code I have so far:
import pygtk
pygtk.require('2.0')
import gtk
import webkit
import gobject
class Browser:
default_site = "https://www.pubnub.com/developers/demos/webrtc/"
def delete_event(self, widget, event, data=None):
return False
def destroy(self, widget, data=None):
gtk.main_quit()
def __init__(self):
gobject.threads_init()
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.window.set_resizable(True)
self.window.connect("delete_event", self.delete_event)
self.window.connect("destroy", self.destroy)
#webkit.WebView allows us to embed a webkit browser
#it takes care of going backwards/fowards/reloading
#it even handles flash
self.web_view = webkit.WebView()
self.settings = self.web_view.get_settings()
self.settings.set_property("enable-java-applet", True)
self.settings.set_property("enable-plugins", True)
self.settings.set_property("enable-scripts", True)
self.settings.set_property("enable-file-access-from-file-uris", True)
self.settings.set_property("enable-private-browsing", False)
self.settings.set_property("enable-spell-checking", False)
self.settings.set_property("enable-universal-access-from-file-uris", True)
self.settings.set_property("enable-dns-prefetching", True)
self.settings.set_property("enable-webaudio", True)
self.settings.set_property("enable-webgl", True)
self.settings.set_property("enable-fullscreen", True)
self.settings.set_property("enable-xss-auditor", True)
self.settings.set_property("javascript-can-open-windows-automatically", True)
self.settings.set_property("enable-media-stream", True)
self.settings.set_property("enable-mediasource", True)
self.web_view.set_settings(self.settings)
self.web_view.open(self.default_site)
toolbar = gtk.Toolbar()
#create the back button and connect the action to
#allow us to go backwards using webkit
self.back_button = gtk.ToolButton(gtk.STOCK_GO_BACK)
self.back_button.connect("clicked", self.go_back)
#same idea for forward button
self.forward_button = gtk.ToolButton(gtk.STOCK_GO_FORWARD)
self.forward_button.connect("clicked", self.go_forward)
#again for refresh
refresh_button = gtk.ToolButton(gtk.STOCK_REFRESH)
refresh_button.connect("clicked", self.refresh)
#add the buttons to the toolbar
toolbar.add(self.back_button)
toolbar.add(self.forward_button)
toolbar.add(refresh_button)
#entry bar for typing in and display URLs, when they type in a site
#and hit enter the on_active function is called
self.url_bar = gtk.Entry()
self.url_bar.connect("activate", self.on_active)
#anytime a site is loaded the update_buttons will be called
self.web_view.connect("load_committed", self.update_buttons)
scroll_window = gtk.ScrolledWindow(None, None)
scroll_window.add(self.web_view)
vbox = gtk.VBox(False, 0)
vbox.pack_start(toolbar, False, True, 0)
vbox.pack_start(self.url_bar, False, True, 0)
vbox.add(scroll_window)
self.window.add(vbox)
self.window.show_all()
def on_active(self, widge, data=None):
'''When the user enters an address in the bar, we check to make
sure they added the http://, if not we add it for them. Once
the url is correct, we just ask webkit to open that site.'''
url = self.url_bar.get_text()
try:
url.index("://")
except:
url = "http://"+url
self.url_bar.set_text(url)
self.web_view.open(url)
def go_back(self, widget, data=None):
'''Webkit will remember the links and this will allow us to go
backwards.'''
self.web_view.go_back()
def go_forward(self, widget, data=None):
'''Webkit will remember the links and this will allow us to go
self.web_view.go_forward()
def refresh(self, widget, data=None):
'''Simple makes webkit reload the current back.'''
self.web_view.reload()
def update_buttons(self, widget, data=None):
'''Gets the current url entry and puts that into the url bar.
It then checks to see if we can go back, if we can it makes the
back button clickable. Then it does the same for the foward
button.'''
self.url_bar.set_text( widget.get_main_frame().get_uri() )
self.back_button.set_sensitive(self.web_view.can_go_back())
self.forward_button.set_sensitive(self.web_view.can_go_forward())
def main(self):
gtk.main()
if __name__ == "__main__":
browser = Browser()
browser.main()
Thank you for any help you can provide. Example code welcomed :)
