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/

Installing FFMPEG on my EC2 instance takes too long ; what am I doing wrong ? [closed]
24 août 2023, par Shaban KhawarI found a good article on how to download onto my EC2 instance : link
Here's the issue. It takes forever ! It takes around 15 minutes to install.


I'm running my EC2 instance on Amazon Linux 2023, so no apt-get for me.
Also my EC2 instance is created by my EB environment, so if auto-scaling occurs, my instance will be terminated and a new one will be created. I can set .ebextensions to run all the commands to install FFMPEG again but as mentioned above, it takes forever ! That means for 15-20 minutes, my server is down because of one dependancy. I feel like I'm going about this the wrong way, so any advice is appreciated.

FFmpeg recorded video is dark with Xvfb and chrome headless on Centos 7
15 juin 2023, par narsy4I am trying to do a video recording of headless chrome session on Centos 7 (Amazon EC2 instance) using ffmpeg. I have installed ffmpeg, Xvfb and google chrome on the machine. I started Xvfb on :99, verified the display using xdpyinfo and started chrome. However when I run the ffmpeg cmd to capture the video (no errors in ffmpeg debug logs), the output is dark with a X sign in the centre of video screen. What am I doing wrong here ? Any help is appreciated.


**Xvfb and chrome commands**
Xvfb :99 -screen 0 1920x1080x24 &
export DISPLAY=:99
google-chrome --headless --disable-gpu --no-sandbox --start-maximized --window-size=1920x1080 https://www.google.com



**FFmpeg command**
ffmpeg -video_size 1920x1080 -framerate 30 -f x11grab -i :99 -loglevel debug -pix_fmt yuv420p /tmp/video.mp4





Searched for and read a few threads on this, but couldn't get it to work.
