xdotool to tab to a button on a web page and use the mouse to disable a drop down menu option
25 juin 2023, par MashI have a Bash script that open a Amazon chime meeting URL in firefox, uses XDOtool to enter a meetig participant name, and tab and mouse click functions. and next uses ffmpeg to stream the video and audio output of the Amazon chime meeting to an RTMP destination.


When this is streamed, the Amazon chime web app has "More" drop down Menu. Within the Menu it has a option to disable the self view. I want to add xdotool commands to disable this self view option from the more drop down menu on the amazon chime web app page.


the Amazon chime meeting URL is - https://app.chime.aws/meetings/
