   private func mergeAssetsAndPlay(assets: [Any]) {
        let videoURLs = assets.compactMap { $0 as? URL }
        let trackItems = videoURLs.map {
            let asset = AVAsset(url: $0)
            let resource = AVAssetTrackResource(asset: asset)
            let item = TrackItem(resource: resource)
            item.videoConfiguration.contentMode = .aspectFit
            return item
        }

        let timeline = Timeline()
        timeline.videoChannel = trackItems
        let compositionGenerator = CompositionGenerator(timeline: timeline)
        let composition = compositionGenerator.buildComposition()
        self.asset = composition
    }

See the issue with the above code. How to set up correct orientation - the same I see f.e. in Photos app
