Choose whether the pause must be reversible
For a temporary microphone mute, the enabled property changes whether a MediaStreamTrack outputs its real media. MDN describes disabled audio as silence and disabled video as black frames. This is a deliberate user mute state, distinct from the muted property which reports a temporary inability to provide data. A black preview after clicking a camera mute control is therefore not sufficient evidence of a broken camera or a missing media codec.
Stopping has another lifecycle
The separate stop method tells the browser that the track no longer needs its source and changes that track to the ended state. Multiple tracks can share a source, so stopping one does not establish that every consumer of the source has stopped. The MDN stop documentation also distinguishes the direct method call from a naturally fired ended event. An application should update its own controls rather than waiting for an event which this action does not dispatch.
Design a useful two button test
An original interface exercise uses a temporary Mute control and a separate Finish capture control. Mute should allow a deliberate return to the same live session; Finish should release the tracks the application owns. Label the buttons by their actual effect and test that their states remain understandable after each action. This concerns application lifecycle handling, not a way to change streaming account limits. Do not claim that one stopped track proves all browser or operating system capture has ceased.
