MPV cannot open SRT streams

[tvadi]

On Ubuntu 20.04

Tried MPV version from sudo apt install mpv
And a MPV version I compiled from https://github.com/mpv-player/mpv using meson build

Just trying to open the SRT stream from OBS
mpv srt://127.0.0.1:10000

This is working on Windows MPV player fine but not on Linux. On Linux, I can open srt://127.0.0.1:10000 successfully in VLC.. From apt install mpv, getting:

No protocol handler found to open URL srt://127.0.0.1:10000 The protocol is either unsupported, or was disabled at compile-time.

From git compile, getting:
[ffmpeg] Protocol not found. Make sure ffmpeg/Libav is compiled with networking support. Failed to open srt://127.0.0.1:10000.

This is my ffmpeg:
