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.
