Broken "publisher" example

[jaques-sam]

When running the publisher example, you'll see the following error: didn't accept URI

❯ GST_DEBUG=3 GST_PLUGIN_PATH=/gst-plugin-opentok/target/debug/ cargo run --example publisher -- --api-key $TOKBOX_API_KEY --session-id --remote

Furthermore the last error is not really correct and is the only thing you'll see without setting GST_DEBUG.

As mentioned in the README of opentok-rs: For now the only supported platform is Linux and 2.19.1 is the only supported version.

You seem to use version 2.25?

[jaques-sam]

Yeah, I updated to see if there is a difference. It's the same with 2.19.

Error! Missing element opentoksink.

Maybe it's related to opentok-rust/opentok-rs#3.

Error! Missing element opentoksink.

did you build it? is GST_PLUGIN_PATH correctly set? when you run gst-inspect-1.0 opentoksink do you see anything? is ldd path/to/libgstopentok...so reporting not-found libraries?

[jaques-sam]

gst-inspect-1.0 opentoksink works, it gives me the plugin details.
ldd shows all libs as existing.

But this is normal as you can see WARN GST_URI gsturi.c:676:gst_element_make_from_uri: opentoksinkremote0 didn't accept URI 'opentok-remote://?key=&token=': OpenTokRemoteLaunchFailed

Error! Missing element opentoksink. just seems like the wrong error message...
Can you try it out? Is fairly fast to see.

Could it be that the stream-id became necessary in the uri?
Another piste could be: opentok-rust/opentok-rs#3.

Sorry I'm not involved in this project anymore. Maybe @thiblahute can help you.
