FTL-SDK is a cross platform SDK written in C to enable sending audio/video to
mixer using FTL service.

This package is not in Fedora as it relies on codecs.
Also, it is very specific to OBS Studio which is only in RPM Fusion.

Installation RPM:
https://fedorauser.fedorapeople.org/Packages/libftl/0.9.14/libftl-0.9.14-1.fc29.x86_64.rpm

.src.rpm and .spec files:
https://fedorauser.fedorapeople.org/Packages/libftl/0.9.14/libftl-0.9.14-1.fc29.src.rpm
https://fedorauser.fedorapeople.org/Packages/libftl/0.9.14/libftl.spec

This is not my first package, I already maintain OBS Studio.
Package is actually result of a bug report[1].

Choose to ignore hardcoded library as it is actually part where it is moved to
proper location, as opposed to where install scripts puts it.
