Do you have any plans allowing GStreamer ?
https://harbour.jolla.com/faq says:
Our current packages are from GStreamer 0.10, for API and ABI stability, the GStreamer 1.x series of releases would be preferable for Harbour.
Since Gstreamer 1.16.1 is shipped now, I would like to know whether there’s an update regarding this.
