When you set up an IPTV player you'll usually be offered two options: add an M3U playlist or log in with Xtream Codes. Both get your channels into the app. They just work differently.
What is an M3U playlist?
An M3U file is a plain-text list of streams. It starts with #EXTM3U, and each channel has an #EXTINF line with its name and attributes, followed by the stream address. Attributes such as tvg-id, tvg-logo and group-title tell the player which guide data, logo and category belong to each channel.
#EXTM3U url-tvg="https://example.com/guide.xml"
#EXTINF:-1 tvg-id="news.example" tvg-logo="https://example.com/news.png" group-title="News",Example News

Xtream Codes is an API that many IPTV platforms support. Instead of a single file, the player signs in with a server URL, username and password, then asks the server for categories, channels and guide data. Our Xtream Codes setup guide walks through it.
Side by side
- Setup: M3U needs one URL; Xtream Codes needs three fields.
- TV guide: Xtream Codes usually loads the guide automatically. M3U may need a separate EPG URL.
- App support: almost every player supports M3U, including VLC. Xtream Codes is supported by most dedicated IPTV players.
- Updates: both refresh when the provider changes the lineup, but Xtream Codes apps tend to handle categories more cleanly.
Which should you use?
If your app supports Xtream Codes, it's usually the smoother experience. Use M3U for apps that only accept playlists, or for a quick test in VLC.
