replay video with tradition has some errors

[Statfine]

const node = this.ctx.video('mp4');
node.startAt(0);
node.stopAt(5);

const node2 = this.ctx.video('mp4');
node2.startAt(2);
node2.stopAt(10);

const node3 = this.ctx.video('mp4');
node3.startAt(7);
node3.stopAt(15);

const node4 = this.ctx.video('mp4');
node4.startAt(15);
node4.stopAt(20);

const node5 = this.ctx.video('mp4');
node5.startAt(20);
node5.stopAt(27);

const crossFade = this.ctx.transition(VideoContext.DEFINITIONS.HORIZONTAL_WIPE);
const crossFade2 = this.ctx.transition(VideoContext.DEFINITIONS.CROSSFADE); // 渐显
const crossFade3 = this.ctx.transition(VideoContext.DEFINITIONS.CROSSFADE); // 渐显
const crossFade4 = this.ctx.transition(VideoContext.DEFINITIONS.CROSSFADE); // 渐显

// 1 2 平移
node.connect(crossFade);
node2.connect(crossFade);
crossFade.transition(2, 5, 0.0, 1.0);

// 2 3 渐显
crossFade.connect(crossFade2); // connect to input of crossfade2 rather than destination.
node3.connect(crossFade2);
crossFade2.connect(this.ctx.destination);
crossFade2.transition(7, 10, 0.0, 1.0);

// 4 无特效
node4.connect(this.ctx.destination);

// 5 开始
node5.connect(crossFade3);
crossFade3.connect(this.ctx.destination);
crossFade3.transition(20, 23, 1.0, 0.0);

The code is like this; first play is all right; but when i replay it after first end; some node show nocontant in this.ctx.registerCallback('nocontent', function () { console.log('nocontent'); }); has something wrong with it or did I make a mistake?

Hi @Statfine
I'm having trouble reproducing this bug, I've used your code and added the following callback to make the VideoContext replay:

this.ctx.registerCallback("ended", ()=>{
    this.ctx.currentTime = 0;
    this.ctx.play();
});

and i'm not seeing any "nocontent" callbacks being called.

Could you confirm that your using the latest build of VideoContext (v0.39.0)? A bug related to this was fixed in 0.38.3.

Kind regards,
Matt

@MatthewShotton you are right; used old version cause this bug. After update it to 0.39; all right.Thanks very much
