RecordingCapable

A PlayerMediaSource that can copy the packets it reads into a file while it plays.

Optional. The engine looks for it on the source, and a source without it makes io.github.yuroyami.kiteplayer.KitePlayer.startRecording throw.

The engine calls these members from its own thread while another thread reads packets, so an implementation guards its recording state itself. The engine ends a recording before it seeks or retires the session, so an implementation never has to put a jump into a file.
