我尝试使用自定义在jwplayer 7.8版中嵌入视频广告。但是它不起作用。请帮助我解决问题
playerInstance.setup({
playlist: [{ image: "", file: ""}],
advertising: {
client: "googima",
schedule: {
pre:{
offset: "pre",
tag: "https://pubads.g.doubleclick.net/gampad/live/ads?iu=/14008522/video-jwp&description_url=https%3A%2F%2Flookandcook.com&env=vp&impl=s&correlator=&tfcd=0&npa=0&gdfp_req=1&output=vast&sz=400x300|640x480|970x90&min_ad_duration=10000&max_ad_duration=15000&unviewed_position_start=1"
}
},
vpaidmode: "insecure"
}
});
