[SECURITY] Fedora 39 Update: gstreamer1-plugin-libav-1.22.7-1.fc39

GStreamer is a streaming media framework, based on graphs of filters which operate on media data. Applications using this library can do anything from real-time sound processing to playing videos, and just about anything else media-related. Its plugin-based architecture means that new data types or processing capabilities can be added simply by installing new plugins. This package provides FFmpeg/LibAV GStreamer plugin.
