Streaming Desktop - core input error: open of 'screen://' failed

[Sparx]

Hi there.

I am trying to stream my desktop on my Debian Stretch using VLC 2.2.6 Umbrella.

I got to File -> Stream -> Capture Device -> Capture mode: Desktop. Then I follow the next steps (Works fine with files). Then I get the error:

Your input can't be opened:
VLC is unable to open the MRL 'screen://'. Check the log for details.

I'm unable to create a log for some reason (despite adding a path to the configuration). However, I've ran VLC in the terminal and I get the error

core input error: open of `screen://' failed

Thanks for reading, if anyone could point me in the right direction, I would be grateful.

Without logs, it cannot be explained.

I managed to get the logs. This is what I get:

Looks like screen capture plugin is not included in your build/installation.

Thank you for your help!

I installed the Debian package vlc-plugin-access-extra and it now works perfectly.

Code: Select all

sudo apt-get install vlc-plugin-access-extra
