Allow gstreamer1.0

[takimata]

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.
In particular, it would be great to be able to:

• link to libgstreamer-1.0.so.0
• having these as allowed dependencies:
  • gstreamer1.0
  • gstreamer1.0-droid
  • gstreamer1.0-plugins-base
  • gstreamer1.0-plugins-good
  • gstreamer1.0-plugins-bad

The remaining problem with Gstreamer is that it doesn't out of the box integrate to the resource policies, who can access what hw and when. Looks like the faq needs updating.

What do you mean with "resource policies"?

Doesn't provide QtMultimedia access to the same hardware components as GStreamer does?
Sure, there are problems when accessing e.g., the camera concurrently, but I think this has to be handled gracefully by the developer.

[pvuorela]

QtMultimedia does but it also automatically handles the resource parts, src/plugins/resourcepolicy/ etc.
App developer doesn't have means to do the same thing unless given an API.

In allowed libraries there is https://git.sailfishos.org/mer-core/libaudioresource which can be used to acquire audio resources from non-Qt app such as SDL apps and it should also help with apps using gstreamer directly.

Ok, so I guess it just depends on having something like a libvideoresource (similar to the libaudioresource available now)...

A short note for me/people who don't know this resourcepolicy stuff:
