What the app can legitimately play, and what it does not do.
IPTelvza is a player: it plays the source that you give it, in Settings → Sources (M3U link or Xtream credentials). Here are sources whose use is legitimate and documented.
The operator publishes the official playlist of its router:
http://mafreebox.freebox.fr/freeboxtv/playlist.m3u. It is only reachable from the
router's own Wi-Fi. Source: assistance.free.fr/articles/99 (in French).
Two things to know:
rtsp;An HDHomeRun network TV tuner publishes its channel list at
http://<ip>/lineup.m3u, where <ip> is the tuner's address on your
network. Source: info.hdhomerun.com/info/http_api.
A server you run at home, such as Tvheadend or Channels DVR, can expose your channels and recordings as a playlist. The exact URL path is found in the software publisher's documentation: refer to it.
Your own videos, stored on a NAS, can be gathered in an M3U playlist and played by IPTelvza.
To try the app without setting anything up, add this playlist:
https://iptelvza.com/demo/films-libres.m3u. It only contains open films from the Blender
Foundation, released under Creative Commons licenses. IPTelvza hosts no copy: each entry points to
the official file on download.blender.org (these files are large).
Logos and trademarks, including Blender's, are excluded from these licenses.
IPTelvza provides no content, no channels and no lists, and recommends none. Cheap “all channels” subscriptions are illegal: do not buy them.
