Enable Camera and Mic preferences on browser?

[DGaffney]

I'm looking to enable camera and mic by default in the preferences - and not getting too far. Tried to implement: https://stackoverflow.com/questions/48007699/how-to-allow-or-deny-notification-geo-location-microphone-camera-pop-up - and getting the following results after running this demo script:

from pyvirtualdisplay import Display
size=(1600, 900)
display = Display(size=size)
display.start()
import undetected_chromedriver as uc
chrome_options = uc.ChromeOptions()  
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument("--user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36")
chrome_options.add_experimental_option("prefs", {
  "profile.default_content_setting_values.media_stream_mic": 1, 
  "profile.default_content_setting_values.media_stream_camera": 1,
  "profile.default_content_setting_values.geolocation": 1, 
  "profile.default_content_setting_values.notifications": 1 
})
chrome = uc.Chrome(version_main=96, options=chrome_options, headless=False)
chrome.get("https://bot.sannysoft.com")
chrome.save_screenshot("screen.png")

Result:

>>> from pyvirtualdisplay import Display
>>> size=(1600, 900)
>>> display = Display(size=size)
>>> display.start()
<pyvirtualdisplay.display.Display object at 0x7f591c435d30>

>>> chrome_options.add_experimental_option("prefs", {

... })
>>> chrome = uc.Chrome(version_main=96, options=chrome_options, headless=False)

Anyone have thoughts on how to fix this?

Hi @DGaffney ,

instead of using prefs, trying this

driver.execute_cdp_cmd(
            "Browser.grantPermissions",
            {
                "origin": YOUR_URL,   # e.g https://www.google.com
                "permissions": ["geolocation", "audioCapture", "displayCapture", "videoCapture",
                                "videoCapturePanTiltZoom"]
            },
        )

this will allow permissions for geolocation, audio, video, and screen capture. but you will have to set the URL upfront.

That seems to work fine with https sites but not http sites - is that part of the spec for these types of permissions?
