Linux: Programs hang when recording from a microphone
Cause: Microphone goes into suspend when idle and do not wake up
Pipewire:
Load the file /usr/share/wireplumber/scripts/node/suspend-node.lua in a editor and change the row
tonumber(node.properties["session.suspend-timeout-seconds"]) or 5
to
tonumber(node.properties["session.suspend-timeout-seconds"]) or 0
And then start the system new
PulseAudio:
Load the file /etc/pulse/default.pa in a editor and change the row
load-module module-suspend-on-idle
to
#load-module module-suspend-on-idle
And then start the system new
Windows: No audio devices are listed
and in the log file, wasapi2src is listed as - not available
[...]
14:36:14 [vokoscreenNG] Symbols: + available, - not available
14:36:14 [vokoscreenNG] + d3d11screencapturesrc

Check if the file gstwasapi2.dll is present in the default installation folder:
C:\Program Files\vokoscreenNG\gstreamer\gstreamer_lib\
Also check if access to the file is blocked by the system, driver or quarantined an antivirus program.
FlatPak: No access to other drives
Flatpak from Flathub is configured very restrictively, allowing access only to the home directory.
To access other drives, Flatpak must be configured accordingly.
Open a terminal and enter the following:
flatpak --user override --filesystem=host com.github.vkohaupt.vokoscreenNG
Never record directly in MP4
It is recommended to always record in *.mkv format and then convert to *.mp4.
Why?
Any video recorded directly in mp4 format can only be used if the video is finalized.
If the video is not finalized, it will be unreadable in its entirety and cannot be repaired.
This can happen
- if the computer crashes
- or has a blue screen
- or a Power failure
- or the hard drive is full
- or if your screencast programm freezes
- or turn off the computer during recording
- or other bad things
Windows: Wrong screen is recorded
Maybe this tip can help.

Flickering, tearing, artefacts
On the screen we see no Flickering, tearing, artefacts, but after the screencasting we play the Video and it is full of Flickering, tearing, artefacts.
It's nice? No. Can we help? I hope.
The most Desktop come with a Compositer for Eye-Candy animation, i love it.
But good for screencasting? Look at the upper image.
One way is to disable compositing, but not for me, see the next image and i can continue to use under Plasma5 my lovely Eye-Candys.
For NVidia cards that can be a solution.
