Recording appears to work, but the resulting file has a length of zero You have selected a codec that is not supported by the container (for example, you tried to use the VP8 video codec with the MP4 container). This error indicates that ffmpeg/libav (the underlying video and audio encoding library) failed to initialize the output file. You don't have permission to write to the output directory. The output directory does not exist (i.e. This error indicates that the output file could not be created. For Ubuntu, this can be done by running: sudo apt-get install libavcodec-extra-53 libavformat-extra-53. Some distributions will omit codecs that have patent issues, but allow you to install them as a separate package. If that doesn't help, then the only solution is to switch to a different window manager, or use OpenGL recording. Uninstalling the driver for 2D acceleration ( xserver-xorg-video-intel, xf86-video-intel or similar). For Intel GPUs, the flickering can sometimes be eliminated by doing one of the following:Ĭhanging the acceleration method from SNA to UXA as described in this article or this video tutorial. Since this is a window manager flaw, other recording software is affected by this too. This is a known problem with some window managers, especially those based on Mutter (the GNOME 3 window manager) and Cinnamon, though other compositing window managers (e.g. The recording occasionally flickers, showing parts of the desktop background instead of windows

On Ubuntu, this can be done by logging out, clicking the 'gear' icon on the login screen and selecting 'Ubuntu on Xorg', and logging back in. The solution is to switch back to the X11 display server. Since Wayland doesn't provide a standardized API for screen capturing, SSR can't support it (yet). Ubuntu 17.10) will by default use the Wayland display server.
