RTCTransformEvent: transformer property
Baseline 2025
Newly available
Since October 2025, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The read-only transformer property of the RTCTransformEvent interface returns the RTCRtpScriptTransformer associated with the event.
The property exposes the WebRTC sender or receiver pipeline as a readable and writable stream of encoded media frames, which a WebRTC Encoded Transform can insert itself into in order to modify frames.
