libgstreamer-opencv1.0-0 1.22.1-1ubuntu1 (riscv64 binary) in ubuntu lunar

 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 plug-ins.
 .
 GStreamer Bad Plug-ins is a set of plug-ins that aren't up to par compared
 to the rest. They might be close to being good quality, but they're missing
 something - be it a good code review, some documentation, a set of tests, a
 real live maintainer, or some actual wide use.
 .
 This package contains shared GStreamer libraries for OpenCV.
