Thank you for your help, Jose! For now I am still fine with Gst::PLAY_PAUSED. I will just wait for the next release then... Thank you!

We haven't been working on wrapping that part of the API because we
weren't aware that anyone would need to use it.  Also, it is fairly new

I can't say for sure.  You might try asking on their mailing lists or
browsing their source code:
