/**
 * SECTION:element-wpesrc
 * @title: wpesrc
 *
 * The wpesrc element is used to produce a video texture representing a web page
 * rendered off-screen by WPE.
 *
 * Starting from WPEBackend-FDO 1.6.x, software rendering support is available. This
 * features allows wpesrc to be used on machines without GPU, and/or for testing
 * purpose. To enable it, set the `LIBGL_ALWAYS_SOFTWARE=true` environment
 * variable and make sure `video/x-raw, format=BGRA` caps are negotiated by the
 * wpesrc element.
 *
 * ## Example launch lines
 *
 * |[
 * gst-launch-1.0 -v wpesrc location="https://gstreamer.freedesktop.org" ! queue ! glimagesink
 * ]|
 * Shows the GStreamer website homepage
 *
 * |[
 * LIBGL_ALWAYS_SOFTWARE=true gst-launch-1.0 -v wpesrc num-buffers=50 location="https://gstreamer.freedesktop.org" ! videoconvert ! pngenc ! multifilesink location=/tmp/snapshot-%05d.png
 * ]|
 * Saves the first 50 video frames generated for the GStreamer website as PNG files in /tmp.
 *
 * |[
 * gst-play-1.0 --videosink gtkglsink wpe://https://gstreamer.freedesktop.org
 * ]|
 * Shows the GStreamer website homepage as played with GstPlayer in a GTK+ window.
