The software I mostly use on Linux is Vokoscreen, never had a problem with it and works like a charm on Linux Mint, Ubuntu and Mageia. But on Fedora, it's a different story.

When I try to open Vokoscreen the following error arises: image description

If I try running it from the terminal I get the same error: image description

I tried google in it, but I get no answers, not to mention the error message doesn't give me any warnings or information to what's wrong or if I need some extra libraries. I tried uninstalling and installing Vokoscreen from different methods:Terminal, downloading the RPM file, using older versions, but everything ends in the same result.

I tried using VLC which crashes when I try to record and GTK recordMyDesktop is a piece of junk that get's stuck in the same frame for the duration of the video.

EasyScreenCast worked like a charm on Fedora 24, but after I downloaded and installed the first OS updates it stopped working, yes I tried going to the Gnome extension site and disabling and enabling it again but still doesn't work. I can still go to the Options tab and all the buttons work, but when I click on 'Start Recording' nothing happens.

How do I get at the very least Vokoscreen or EasyScreenCast to work once again?

I get this error now:

It looks like it crashed while looking for external tools. On my system, I show it searching for ffmpeg and pactl.

Maybe see if ffmpeg is working properly.

See if you can grab a single frame of a video file as a jpg:

ffmpeg -ss 1 -i "somefile.mp4" -vframes 1 -an -vcodec mjpeg -f rawvideo "somefile.jpg"

I get an error.

Then that is the first problem you need to solve. Try uninstalling and re-installing ffmpeg and it's dependencies.

How do I do that? su dnf remove ffmpeg?

patxi gravatar imagepatxi ( 2016-07-25 07:55:25 -0500 )edit

first read this
If you already have installed RPMFusion Repos (point 8) then, for install ffmpeg

sudo dnf install ffmpeg


for uninstall(remove)

sudo dnf remove ffmpeg

ffmpeg -ss 1 -i "somefile.mp4" -vframes 1 -an -vcodec mjpeg -f rawvideo "somefile.jpg"

but in vokoscreen i got the same output
