Navigation events test (mouse inputs) - wpesrc

General Discussion
1

Im trying to test navigation event using the sample in:

gst-launch-1.0 wpesrc location=https://gstreamer.freedesktop.org/documentation/ ! queue ! webrtcsink enable-data-channel-navigation=true meta="meta,name=web-stream"

gst-launch-1.0 webrtcsrc signaller::producer-peer-id=<webrtcsink-peer-id> enable-data-channel-navigation=true ! videoconvert ! autovideosink

but I can not get the element wpesrc to work or to install it.
WARNING: erroneous pipeline: no element “wpesrc”

Im running ubuntu and I have already install packages
sudo apt install libwpewebkit-1.0-3
libwpewebkit-1.0-dev
libwpewebkit-1.0-doc
wpewebkit-driver

as well as compile gstreamer with

-Dgst-plugins-bad:wpe=enabled

Trying with navigation-enabled I always get this errors on each mouse/keyboard event (Could not send event)

please help to get wpesrc install or any other recommend way to test navigation events?

Thanks

Is gst-inspect-1.0 wpe showing anything?

Do you have libgstwpe.so in your build?

If so try to inspect it too.

Thanks Philn. you are right, the element is also not present in the gst-inspect-1.0.

I fixed it this way just in case someone else need it:

apt install libwpewebkit-1.0-3 libwpewebkit-1.0-dev libwpewebkit-1.0-doc wpewebkit-driver
## WPE
    git clone https://github.com/Igalia/WPEBackend-fdo.git
    cd WPEBackend-fdo
    meson build --prefix /usr/local/
    meson install -C build/
    ```
recompile/install gstreamer with :
-Dgst-plugins-bad:wpe=enabled
