Hi,
Thank you very much to have taken time to answer and make this example on ember-twiddle !
In your example the buttons are “childs” of the video-player component, so it’s look more like my first example. What I want is the buttons to be “brothers” of the video component.
I’ve made a test on twiddle, and I did try with a “observer” on a property “extractToPlay” of the video-player component. It work but : 1/ We can’t restart an extract by pressing a second time on the same button, as the property “extractToPlay” don’t change and the observer don’t fire. 2/ This solution seems to me “twisted” and I’m very not sure that it’s the ember-way to do that sort of thing ?
