vokoscreenNG won't start, says "No videocodec found"

id flag

I just upgraded from Ubuntu 20.04 to 22.04. Now when I open vokoscreenNG, I see this message:

No videocodec found

Please install package

gstreatmer-plugins-base
gstreatmer-plugins-good
gstreatmer-plugins-bad
gstreatmer-plugins-ugly
gstreatmer-plugins-libav

No videocodec found

Does anyone know how to solve it?

Update:

Those packages are already installed. I uninstalled vokoscreenNG 3.4 and installed vokoscreenNG 3.1.0. Now I don't see the message above but I cannot choose mp4 format because no videocodecs are listed and when I choose any other format (mkv, webm, avi, mov), Vokoscreen will record the video but won't play back the file - it shows this message:

To play this video a codec is needed. Please install a codec pack.

But all codecs are installed and I can play the videos in VLC player.

It's as though Vokoscreen is looking in the wrong location for the codecs.

Any ideas on how to fix it?

A good start is to install the packages it is asking for.

I had the same difficulty and discovered you can install the required codecs with the following commands:

Open a terminal window. Required package is in the multiverse repo so :

sudo add-apt-repository multiverse

Next, you'll run update:

sudo apt update

Finally, install the codecs from the restricted extras:

sudo apt install ubuntu-restricted-extras

You will be warned about the repo

end user license agreement

Tab to the button and press

select yes on EULA

You'll have to accept with the button.

Everything will install and you'll have the codecs and VokoScreen will run properly.

You can install the correct codecs

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
