When adding a playlist to your IPTV app, you usually have two choices: entering an M3U URL or using the Xtream Codes API. Here is a breakdown of both.
M3U Playlists
M3U is a universally accepted text format that lists media links. It's simple but can be difficult to manage if the list is massive, and it doesn't organize Live TV and VOD cleanly by itself.
Xtream Codes API
Xtream API allows the app to fetch data directly from the server in a structured way. This usually results in a much faster, better-organized interface with clear categories for Live, Movies, and Series.
