The latest pre-release adds support for .strm files. These are common in the Kodi world and the format has been around for a while.
.strm files are like Stream Links. They are plain text files that contain a URL to a video file.
When imported, the video URL will be part of the record in your Channels library and Channels will use that URL to play the video.
You add these to your library just like Stream Links. Just name the file in a way the scanner expects, and it will be added to your library.
Caveats
This only works on iOS and tvOS client for now.
Browser player support is still early.
This is very early and has yet to be tested with remote streaming and in some other scenarios.
This has yet to be tested with a large amount of video formats and streaming protocols.
Help
If you already have a bunch of .strm files, or have a means to use this, please start trying it and reporting back any issues you run into. We can hopefully knock out weird bugs in this topic.
