Simple Screen Recorder records sound only with black screen

[KhitMinnyo]

I am using Kali Linux 2017.1 64bit Version
I installed SimpleScreenRecorder and recorded many screen-castings.
But, Now, I'm facing a knotty problem.
SSR records sound but not include Screencasting .

Please, Help me with this.

Thanks

I'm facing the same issue on Fedora 26 64bit

This seems to be an issue with Wayland, which is the default with modern Fedora distributions. Switching to X11 resolves this issue.

which makes this another duplicate of #431

I agree. AFAIC this one can be closed as duplicate.

Thank for your help. Now I'm OK. Thanks

I just had this problem on Debian 10 Buster a year and half later after this issue was initially opened.

Switching back to X11 fixed the issue. But I was curious if there are plans to support Wayland in future?

Thanks

Hello, I don't know if you have fixed this bug but if you haven't let me help out because I ran into the same issue. Here's a solution for it, NOT REALLY A PERMANENT ONE but on the user side that will take you throughout the period of using your OS (I'm running on Fedora 30 and I equally encountered it on the Fedora 32 all fixed with this approach):

Your need to Configure Xorg as the default GNOME session. On your terminal open your custom.conf by typing this command sudo nano /etc/gdm/custom.conf and uncomment WaylandEnable=false if it's commented but must be set to false

Then, on the [daemon] section just under WaylandEnable=false add this line DefaultSession=gnome-xorg.desktop and save the file. restart your system and try running your Screen Recorder program again.
Congratulations.

However, if nano command is not working please try installing it by running the command
sudo dnf install nano or sudo apt-get install nano whichever one works for you.

Thanks, I'll try it if I bump into the issue again. IIRC, last time I switched my login to X11 to resolve the issue.

It can be fixed by following the instructions in #565 (comment)

1. open /etc/gdm/custom.conf in a text editor as root
2. change the [deamon] group to the example below

[daemon]
WaylandEnable=false
DefaultSession=gnome-xorg.desktop

3. reboot

After the reboot, the enviroment is changed to:

$ echo $XDG_SESSION_TYPE
x11

$ loginctl show-session 2 -p Type
Type=x11

Do try viewing the recording file in another viewer or browser before trying more complicated things.

I have this strange situation where for one particular recording (.mp4) file, VLC on Lubuntu shows me garbled video (sometimes just a black screen, sometimes flickering black and white rectangles) with good audio. Fortunately I happened to think out about trying to view the file in another viewer (Firefox browser) and that shows both video and audio perfect! Here are the details:

Lubuntu 19.04 Disco
LXQt 0.14.1
recording file: .mp4, 53.6 MiB, about 30 minutes long
SimpleScreenRecorder 0.3.11
VLC media player 3.0.8 Vetinari (revision 3.0.8-0-gf350b6b5a7)
