I'm trying to send click to youtube video to start playing

1 Tried SendMouseClickEvent:

    TempEvent.x         := X;
    TempEvent.y         := Y;
    TempEvent.modifiers := EVENTFLAG_IS_LEFT;

    DeviceToLogical(TempEvent, GlobalCEFApp.DeviceScaleFactor);
    Chromium.SendMouseClickEvent(@TempEvent, MBT_LEFT, False, 1);

but this didn't work

2 Tried SendMessage() to CEFWindowParent.Handle - this also didn't work

3 Tried to emulate clicks via js - this sometimes worked.
Sometimes didn't. Rather strange. No errors were reported.

Which is the reliable way to send clicks? Or do I need something more to make playing?

Hi,

Try changing the autoplay policy in your application with this :

Code: Select all

GlobalCEFApp.AutoplayPolicy := appNoUserGestureRequired;

If you control the web page contents then add an "autoplay" parameter to the YouTube link like this :
https://stackoverflow.com/questions/340 ... or-youtube

The SimpleOSRBrowser demo calls TChromium.SendMouseClickEvent for the OnMouseUp and OnMouseDown events. Perhaps you need to emulate both events.

Setting AutoplayPolicyappeared to be enough. Js version of clicks now also seems to work always

Thank you very much!
