Show HTML from HDMI in Jessie lite

Sun Sep 24, 2017 9:02 pm

On Raspbian Jessie Lite, is it possible to show HTML pages through HDMI using node and webkit? I am not sure on the internals of the Pi for custom graphics, so this question.

It is however possible to stream videos using omxplayer and show images using

Code: Select all

fbi
, so I was wondering is there a similar way to show some graphics as well using HTML/JS to offer somekind of little lightweight media control, without using the full rasbian desktop or OSMC or whatever.

PS - Good to know of any lib/npm packages which does this.

To have any remotely decent performance you need a system that utilizes the GPU for rendering. The only system *that I know of* is Qt5 built for eglfs and including their webengine. I had a plan to get to do this and provide binaries for people who dont want to compile Qt5 themselves but havent gotten that far. (webengine need a *lot* of memory to build to crosscompiling seems to be the only reasonable solution) Someone else might have done it though.

WebKit was replaced by WebEngine in Qt5.6 (or something) but today I learned there is an alternative called Oxide https://www.openhub.net/p/oxide-webengine which also looks interesting.

Thanks for that. You mentioned you were trying out something. Can you post a gist of work?
Maybe I can get some idea on implementing it with python qt bindings.
