How to install InputStream Adaptive?

Quote from sparkplug

Some of my add-ons need inputstream-adaptive ..The way I see to install it is with apt. However Libeelec does not have apt.

Any help is appreciated.

Its available as an addon

Not sure the version you are referring to. The addon versions are (depending if you are running LE12.2 or LE13):

- 22.3.6-Piers

- 21.5.18-Omega

Please share the logs if still an issue.

The image you are using is a previous release of LE13. Please update to the current release to be able to install addons. The current addon releases are 12.80.5. You will be able to find the current LE13 images at - https://test.libreelec.tv/13.0/
