HTML inputs =========== HTML inputs are used for on-the-fly generated graphics, ie. typically animated overlay graphics that cannot be simple still pictures. They allow you to write graphics in full HTML5 (including JavaScript) by way of `Chromium Embedded Framework `_ (CEF for short), a library that basically embeds a full copy of the Chromium web browser into Nageru. HTML inputs are available from Nageru 1.7.0 onwards, but note that they are an optional component, since many distributions don't carry CEF. Thus, your copy of Nageru may not support them. See :ref:`compiling` for information on how to build Nageru with CEF. Due to CEF performance issues, Nageru does not currently run CEF with GPU rendering enabled, even though the rest of Nageru is very much centered around the GPU. In particular, this means you do not currently have WebGL support. Basic HTML inputs ----------------- In many ways, HTML inputs are similar to :doc:`video inputs
