How do I convert an IP to m3u8?

New to this IPTV stuff and I have an IP, example:

http://streamproviderabcd.com:8080/12345678/12345678/stream 

And the website I'm adding this stream only accepts m3u8s, MOVs, MP4s, MKVs and WEBMs and I've tried with all of them but it doesn't work, how can I convert the stream?

​

Thanks in advance!
