|
|
* 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.
