opengl - SCNProgram - video input -


how can attach video input scnprogram in scenekit?

without using custom program, do:

func set(video player: avplayer, on node: scnnode) {     let size = player.currentitem!.asset.tracks(         withmediatype: avmediatypevideo).first!.naturalsize     let videonode = skvideonode(avplayer: player)     videonode.position = cgpoint(x: size.width/2, y: size.height/2)     videonode.size = size     let canvasscene = skscene()     canvasscene.size = size     canvasscene.addchild(videonode)      let material = scnmaterial()     material.diffuse.contents = canvasscene     node.geometry?.materials = [material] }

which renders video skscene , uses input scnmaterial.

i'd use scnprogram on node, not figure out attach player input. don't mind if solution doesn't uses skscene intermediate rendering. sounds better if it's possible without.

have tried using avplayerlayer, subclass of calayer ? can feed calayer contents property of scnmaterialproperty.

javascript - Access directive function from component class or template -

i've got component needs call function in mydirective can't figure out how gain access it, keeps spewing out errors no matter try. i looked @ view child in docs didn't work me, don't show template usage can't sure if i'm doing right. edit: i think it's important note directive imports component, importing directive component seems give circular reference, causing mydirective become undefined if try inject directives:[] part of @component decorator. what need this: component: import {mydirective} 'my-directive.directive'; // shortened example's sake @component({ directives: [mydirective] }) export class { @viewchild(mydirective) mydir: mydirective; } component template: <button (click)="mydir.mydirectivefunc()"></button> what don't want declare mydirective on button because add undesired behavior. want gain access functions. how can this?
