trackData.md

t🛤 TrackData applet

Manages MediaStreamTrack information.

Storage

An array of trackData objects:

trackData = {
        id,
        kind,
        label,
        readyState,
        streamId,
        sourceUrl,
        time,
        settings, 
        tabId
    }

settings.mjs defaults sets trackData to an empty array on startup.

Modules

Background

Monitors chome.tabs changes that could result in the stream / track being closed and removes them from storage.

Checks the storage object on start-up.

Note: MAP not allowed in Chrome Storage.

Content

Listens for GUM_STREAM_START, gets tracks from the stream transferred from inject and monitors for track changes. Storage is updated on changes.

TODO: handled cloned tracks. Cloned tracks are never passed to the content script.
