gstreamer requirements are missing

[jaques-sam]

It's not clear which gstreamer installs are needed for this to build, it definitely requires already:
gstreamer-1.0 >= 1.8
gstreamer-video-1.0 >= 1.8
Possibly more...

As a rule of thumb, you should install the latest stable release. Currently it's 1.22, but versions as old as 1.18 are also known to work.

Tried the examples again on my fedora, but they fail because of this error:

Error! Missing element opentoksink

The examples from opentok-rs work and the opentok lib are properly installed as was mentioned on the README.
So how come it's not finding opentoksink?

Okay, found out after building the plugin, the GST_PLUGIN_PATH env variable needed to be set with the location of the plugin. Good to add to the readme ;-)
