g_signal_emit_by_name won't accept correct argument type

[maxmcd]

This fails with BoolError("Incompatible argument types")

let opus_caps = gst::Caps::from_str(&rtp_caps_opus).unwrap();
webrtc
    .emit("add-transceiver", &[&3i32, &opus_caps])
    .unwrap();

add-transceiver accepts direction and caps.

I've tried a few values for the direction:

gstreamer_webrtc_sys::GST_WEBRTC_RTP_TRANSCEIVER_DIRECTION_RECVONLY
&(gstreamer_webrtc_sys::GST_WEBRTC_RTP_TRANSCEIVER_DIRECTION_RECVONLY).to_value()
&(gstreamer_webrtc_sys::GST_WEBRTC_RTP_TRANSCEIVER_DIRECTION_RECVONLY
    as gstreamer_webrtc_sys::GstWebRTCRTPTransceiverDirection)
    .to_value(),
// etc....

Wondering if I'm missing a way to pass the type.

Hmm, this issue also might be better suited on gtk-rs/sys happy to move it over there if that's suggested.

fwiw, it sucessfully sets the caps if I simply remove the type check: object.rs#L888

The problem here is that the enum was not included in the bindings. You should now be able to simply use &gst_webrtc::WebRTCRTPTransceiverDirection::Recvonly
