2. WPEFramework

WPEFramework provides a unified web-based interface with a consistent navigation model. In this model, plugins (custom or generic) are controlled and queried, through the WPEFramework application.

   /usr/bin/WPEFramework-1.0.0000000
   /usr/bin/WPEProcess -> WPEProcess-1.0.0000000 (each out-of-process plugin will run in a seperate WPEProcess)
   /usr/bin/WPEProcess-1.0.0000000
   /usr/bin/WPEcdmiWPEFramework -> WPEFramework-1.0.0000000 (main WPEFramework process, started with systemd, Controller and in-process plugins run in this process)

...

WPEFramework runs as a systemd service. The main process is named WPEcdmi (it needs to be renamed to WPEFramework ) and runs the main controller plugin as well as the other in-process plugins (such as monitor, tracing etc).

The main WPEFramework process "WPEcdmiWPEFramework" uses ~3MB RES memory with monitor, trace and deviceinfo plugins enabled. WPEProcess (OCDM) plugin is using 6MB (in idle state, it uses more when there are active DRM sessions).

...

WebKitBrowserPlugin allows WPEFramework clients to launch WPE instances, set the URL, suspend&resume browser processes. It works similar to rdkbrowser2 but instead of the rtRemote interface, HTTP API is used.
