Chromium-browser not creating screenshot

[Aardappeltaart]

I'm trying out the chromium-browser on a headless RPI4 Raspbian Lite:

Code: Select all

chromium-browser --version
Chromium 74.0.3729.157 Built on Raspbian , running on Raspbian 10

I'm not able to create a screenshot running headless:

Code: Select all

chromium-browser  --window-size=1280,1024 --screenshot --headless https://raspberrypi.org

No screenshot.png created.

Is --screenshot not supported on the pi, or do I need extra packages?

Forget that --screenshot parm. Install scrot and us that to capture what you need.

scrot is already installed by default and linked to [Print Screen] key.

Thx, but can you run scrot on a headless Pi?

--screenshot --headless is for running chromium on servers, and create screenshots for automated testing, so without X11

Quite nice actually.

Should file a bug report then, but where?

(BTW also selenium could not create screenshot)

[DougieLawson]

If you run the RealVNC server you can run scrot with

DISPLAY=:0 scrot ...

from a command line.

[Aardappeltaart]

yeah, but

Code: Select all

giblib error: Can't open X display. It *is* running, yeah?

And not using realvnc

AFAIK Chromium-browser can be installed on all debian/ubuntu based server installs (x64 & arm) to run headless/

Just tried it on Ubuntu Server on x64 and ARM, so why can't it be done on the Pi?

Probably because the code is broken. Get you coding pencil, your pencil sharpener and a coding pad. The source code is available.

Thanks for the advice,

IMHO a bug report is the better option here.

Anybody knows the appropriate place for that, could be related to the special RPI fixes (GPU accelerated)

Yes, it's working now.

Code: Select all

sudo apt full-upgrade
chromium-browser --version
 --disable-quic --enable-tcp-fast-open --ppapi-flash-path=/usr/lib/chromium-browser/libpepflashplayer.so --ppapi-flash-args=enable_stagevideo_auto=0 --ppapi-flash-version=

This ssh command now saves a nice screenshot.png in home:

Code: Select all

ssh pi4 chromium-browser  --window-size=1280,1024 --screenshot --headless https://raspberrypi.org

Thx all.
