context menu: Work on arbitrary links

[chrysn]

The Firefox plugin works quite well when working on plain video files hosted on a HTTP server, but becomes unusable when those can't be opened in Firefox. For example, I can open an MP4 file easily, it starts playing, and then I can right-click on it or use the menu button to send it to Kodi, but when dealing with AVI or MKV files (which would only be offered for download and not played on-screen in Firefox), neither option works.

On Android (using the Kore app), I can long-press on the .mkv link and share it to Kodi; it would be nice if that'd work on arbitrary links from Firefox as well.

As I understand, the "Play on Kodi" context menu item is only shown if the plugin detects a URI on one of the centralized video platforms behind the link, but not for arbitrary links to avoid cluttering the user interface. That "Play on Kodi" should be shown could (in addition to the existing checks for recognized platforms) be detected by file name extension heuristics, or by inspecting the type attribute of the link (eg. when it matches video/*, or any playlist's media type when #41 is resolved).
