Description

This set of GStreamer plugins may be needed by some games and multimedia applications to play audio and/or video content.
See Missing libgstreamer1 library for more details.

Resolution

On CrossOver 17 and greater, the simplest solution to fix this issue is to run:

/path/to/cxoffice/bin/cxfix missinggstreamer1libav missinggstreamer1libav.amd64

Or add --show-all to see how CrossOver would fix it on your platform and others.

Alternatively you may try one of the commands below.

• For 32-bit Windows applications
  32-bit Arch Linux : pacman -Syu gst-libav
  Debian : apt-get install gstreamer1.0-libav:i386
• For 64-bit Windows applications
  Arch Linux : pacman -Syu gst-libav
  Debian : apt-get install gstreamer1.0-libav:amd64

Notes:

• Neither Fedora nor openSUSE have the Libav GStreamer plugins.
• The 64-bit Arch Linux does not have the 32-bit Libav GStreamer plugins.
• cxfix --show-all may have more up-to-date fixes.
• The commands usually also apply to derived distributions. So for instance a fix for Debian is typically also applicable to Ubuntu, Linux Mint, Deepin and Pop! OS. Similarly a fix for Fedora likely also works on Red Hat Enterprise Linux, CentOS, etc.
