janus-recordplay-plugin

Typed, independently installable bindings for janus.plugin.recordplay. This distribution depends on janus-api-core and no other named Janus plugin.

from janus_api.models.base import Jsep
from janus_recordplay_plugin import RecordPlayPlugin

media = RecordPlayPlugin(session=session)
await media.attach()

# Recording: the browser offers and Janus answers.
recording = await media.record("demo", Jsep(type="offer", sdp=offer_sdp))

# Playback: Janus offers first, then the browser answers.
preparing = await media.play(recording_id=1234)
await media.start(Jsep(type="answer", sdp=answer_sdp))

The client deliberately encodes the asymmetric JSEP state machine: record requires an offer, play rejects JSEP entirely, and start requires an answer. It also preserves Janus's synchronous/asynchronous split: list, update, and configure wait for immediate plugin data; media-state requests wait for their event.

The schemas include the current update recording and restart playback options in Janus, plus the exact hyphenated wire keys used by configure. See the official Record&Play API and recordings format.
