Chrome doesn't enter to full screen mode


I try to record a 1280x720 video through Jibri. Recording work fine, but chrome doesn’t go to full screen. Record example from the jibri server:

The green frame above mean real video size 1280x720. But part of screen is black, so the main image is reduced.

I’ve tried to change chromeOptions, such as

this does not work for me

ffmpeg resolution is:
val resolution: String = “1280x720”,

xorg-video-dummy.conf Display part is:
Section “Screen”
Identifier “dummy_screen”
Device “dummy_videocard”
Monitor “dummy_monitor”
DefaultDepth 24
SubSection “Display”
Viewport 0 0
Depth 24
Modes …
Virtual 1280 720

Package: google-chrome-stable
Version: 89.0.4389.114-1

chromedriver version: 89.0.4389.23

Help solve this, please

I found way to solve prolem.
[jibri src] I removed the “–start-maximized” flag and inserted “–window-size=1280,720” to chromeOptions.addArguments().
Only this options combination works in my case.

PS: window-size option uses “comma” not a “x”
PS2: use the two shot hyphen (-) before option name, this forum merges it to one long (–)


Hi! Where exactly did you change these parameters? Thanks!!

EDIT: Sorry, I figured out where to change these options: /etc/jitsi/jibri/jibri.conf
