Just open index.php or embed.php (if you use CPanel). Then, scroll down and add this code above tracks like this.
"advertising": { "client": "vast", "adscheduleid": "Az87bY12", "schedule": [ { "tag": "https://playertest.longtailvideo.com/vast-30s-ad.xml" } ] },
If you want to customize the number of seconds before the Skip button is displayed. Just add this code above tracks like this.
advertising: { client: "vast", tag: "https://playertest.longtailvideo.com/vast-30s-ad.xml", skipoffset: 10, skipmessage: "Skip this ad in XX" },
If you want to add multi vast ads. Just use this code (also above tracks).
"advertising": { "client": "vast", "adscheduleid": "Az87bY12", "schedule": [ { "offset": "pre", "tag": "https://www.domain.com/adtag.xml" }, { "offset": 10, "tag": "https://www.domain.com/adtag-mid-roll1.xml" }, { "offset": "00:00:15:000", "tag": "https://www.domain.com/adtag-mid-roll2.xml" }, { "offset": "25%", "tag": "https://www.domain.com/adtag-mid-roll3.xml" }, { "offset": "post", "tag": "https://www.domain.com/adtag-post-roll.xml" } ] },
That’s all. Thank you for reading!
