Do you have the iptv links already , for you to do restreming server
Ok I’m confused

or your mixing the 2 things up here
1. A restreaming severs is so you can sell your own iptv stream to resellers, when you do packages like 30 , 60 , 90 days for so many channel, that are locked by a token and other thing, plus auto monthly billing
Not so friends can watch anything
2. When buying iptv subscription 99% of places will give you a app to watch it on you will be very lucky to get a m3u channel playlist ,
If you did get the playlist then why not just load it into Ovoo or any app you wonted and let your friends use it for , as long as the server it’s on is good then it’s shouldn’t buffer
You forgot to tell him
If you want to restream
1. You need servers min. 2 servers one main (on main you install mysql, panel etc) and LBs (Loadbalancer) from those servers you do restream (putting channels on LBs)
2. you need number of connections (channels that you can use at same time)
example :
you buy 100 cxn and you can start max 100 different channels at same time or when is on demand you can have users that watching 100 different channels.
2. If you buy subscription you get few cxn (usually 1-3cxn) and that means if you put on OVOO and have users when you reach max cnx then you have problems like channels start resetting, channels goes down etc.
From any provider who give you his dns , port , username and password you can download m3u
http://DNS: PORT/get.php?username=USERNAME&password=PASSWORD&type=m3u&output=mpegts
or with options(to see categories in m3u list)
http://DNS: PORT/get.php?username=USERNAME&password=PASSWORD&type=m3u_plus&output=mpegts
*There is space between : Port it should be together but getting smiley there
When you have those data just copy and paste in browser you will download playlist.
Advice
If you want to do restream , after setting up servers for restream, from your servers you can do whatever you want but usually it goes for restream like this.
1. selling per cxn for other restreamers
2. selling end users
3. (like you said) getting resellers and selling them credit and they buying that credit and they sell for end users
4. (i dont like this but people do it anyway)
Setting up Webplayer like OVOO and streaming online
If you taking subscription
then you can only watch , there is no point to getting servers for few cxn because you cant get more users.
