I just installed the gstreamer tools using:

sudo apt install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio

and it installed succesfully without any errors. Then: all tools appeared in my terminal

but if I try to launch simple code, like

gst-launch-1.0 fakesrc

it gives the error in output without any comprehensive logs:

ERROR: pipeline could not be constructed: no element "fakesrc".

so, is it not possible to install gstreamer properly in Ubuntu 22.10 or there should be any another installation command?

I tryed gstreamer:No such element or plugin 'videotestsrc' but without any success

It could be one of many things.

Run gst-inspect-1.0 and see what all elements the tool detects.

If it did not detect any of the elements (you have installed good, bad, ugly plugins so it should be a lot of elements) then probably check your GST_PLUGINS_PATH and LD_LIBRARY_PATH and LIBRARY_PATH. If it is set to something custom, then it might not be able to detect.

Delete the file in $HOME/.cache/gstreamer-1.0/* It might have some cached entries for plugins and may be is not able to detect it.
