Hi All! Im try use AVPlayer for IPTV live stream (MacOS App). Use remote server with iptv.m3u file. Remote file iptv.m3u have some code (many streams TV channels):

#EXTM3U url-tvg="http://iptv.myserver.net/epg.xml" m3uautoload="1" deinterlace="7" aspect-ratio="none" cache="2000" tvg-shift="0"

Im use AVPlayer and initialize with simple code:

class VideoItem: ObservableObject {
    
    @Published var player: AVPlayer = AVPlayer()
    @Published var playerItem: AVPlayerItem?

    let myURL = URL(string: "http://iptv.myserver.net/iptv.m3u")! //not real url
    let asset = AVURLAsset(url: url)
    let playerItem = AVPlayerItem(asset: asset)
    self.playerItem = playerItem
    player.replaceCurrentItem(with: playerItem)
    player.play()
}

and player works nice, but im see only "Channel 1" and not selected other! Im have asset, playerItem, player but not understand the way how Im create a channel list (playlist) and select a channel from this playlist to play. Where stored info data about all TV channels after dowloaded remote iptv.m3u file? Please help!
