In order to show ads you need to configure the player to do so. There are two alternatives: Either configure them in the platform or configure them manually for the player.
Configure ads in the platform
If FPFlowplayerViewController was prepared with a valid FPFlowplayerMedia then a Flowplayer config will be fetched and all the ads that are included in this config will automatically play at their specified time offsets.
Configure ads manually
If you wish to prepare FPFlowplayerViewController with an FPExternalMedia and you need to add ads for this video, then you will also need to create an FPAdSchedule and pass the latter as an argument in the constructor of your FPExternalMedia.
There are two ways to create an FPAdSchedule - either by using a VMAP file or defining ad breaks by hand.
Using VMAP
Create an FPAdSchedule with a URL to an ad playlist, such as VMAP
let adSchedule = FPAdSchedule(adScheduleUrl: "https://link.to.a.vmap.file")
let externalMedia = FPExternalMedia(mediaUrl: URL(string: "https://link.to.a.media.file")!, adSchedule: adSchedule)
Defining ad breaks manually
Create an FPAdSchedule with a list of FPAdBreak objects, where each FPAdBreak consists of one or more ad tag URLs (such as VAST) and an offset which indicates the time when the break should start.
The following example creates an ad schedule that consists of:
a pre-roll break with a single ad,
a mid-roll break with three ads which starts 15 seconds into the playback,
a post-roll break with a single ad.
let preRollBreak = FPAdBreak(adTag: "https://link.to.a.vast.file", roll: .pre)
let midRolls = ["https://link.to.a.vast.file", "https://link.to.a.vast.file", "https://link.to.a.vast.file"]
let midRollBreak = FPAdBreak(adTags: midRolls, offset: 15)
let postRollBreak = FPAdBreak(adTag: "https://link.to.a.vast.file", roll: .post)
let adSchedule = FPAdSchedule(adScheduleWaterfall: [preRollBreak, midRollBreak, postRollBreak])
let externalMedia = FPExternalMedia(mediaUrl: URL(string: "https://link.to.a.media.file")!, adSchedule: adSchedule)
