ReadonlyisReadonlytrackReadonlytypeSubscribes to the data track to receive frames.
A stream that yields DataTrackFrames as they arrive.
An application may call subscribe more than once to process frames in
multiple places. For example, one async task might plot values on a graph
while another writes them to a file.
Internally, only the first call to subscribe communicates with the SFU and
allocates the resources required to receive frames. Additional subscriptions
reuse the same underlying pipeline and do not trigger additional signaling.
Note that newly created subscriptions only receive frames published after the initial subscription is established.
Optionaloptions: DataTrackSubscribeOptions
Configure how incoming frames for this track are processed before they are handed out to subscribers (the "pipeline"). These options apply to all current and future subscriptions of this track, and may be set at any time.
