For those interested in learning Edje and wonder what is the so called
"external" support, here is a small demo video player that I wrote
entirely in Emotion. You need the last Emotion to get the position in
slider.
PS: I'm not in the mood for wiki, if you are please add it there somewhere :-)
/*
Super-concise video player example using Edje/Emotion/Elementary.
This is all in Edje by means of type:EXTERNAL, you don't need any C
code other than emotion and edje installed with edje_external
support enabled.
Compile: edje_cc emotion-elementary-externals.edc
Run....: edje_player emotion-elementary-externals.edj
