Used

• Create the video exporter provider.

let provider = VideoX.Provider.init(with: ``URL Link``)

Or

let provider = VideoX.Provider.init(with: ``AVAsset``)

• Create filter instruction and add filters.

let filters: [C7FilterProtocol] = [
    C7LookupTable(name: "lut_abao"),
    C7SplitScreen(type: .two),
]
let filters2: [C7FilterProtocol] = [
    C7Flip(horizontal: true, vertical: true),
    C7SoulOut(soul: 0.3),
]

let filtering = FilterInstruction { buffer, time, callback in
    if time >= 0, time < 10 {
        let dest = BoxxIO(element: buffer, filters: filters)
        dest.transmitOutput(success: callback)
    } else {
        let dest = BoxxIO(element: buffer, filters: filters2)
        dest.transmitOutput(success: callback)
    }
}

• Convert video and then convert buffer.

let exporter = VideoX.init(provider: provider)

/// Export the video.
/// - Parameters:
///   - options: Setup other parameters about export video.
///   - instructions: Operation procedure.
///   - complete: The conversion is complete, including success or failure.
exporter.export(options: [
    .OptimizeForNetworkUse: true,
    .ExportSessionTimeRange: TimeRangeType.range(5...28.0),
], instructions: [filtering], complete: { res in
    // do somthing..
}, progress: { pro in
    // progressing..
})
