'stream' returns the stream of "what the element is playing" --- whatever the element is currently playing, after its volume and playbackrate are taken into account. While the element is not playing (e.g. because it's paused, seeking, or buffering), the stream is blocked. When the element is in the ended state, the stream is in the ended state. When something else causes this stream to be blocked, we block the output of the media element. | |||
When 'captureAudio' is set, the element does not produce direct audio output. Audio output is still sent to 'stream'. | |||
'src' can be set to a Stream. Blocked streams play silence and show the last video frame. | |||
