Spec https://w3c.github.io/webrtc-encoded-transform/#RTCEncodedVideoFrameMetadata particularly PR#173 <https://github.com/w3c/webrtc-encoded-transform/pull/173>. Summary Add a 'timestamp' field to RTCEncodedVideoFrameMetadata containing the presentation timestamp of the associated encoded video frame. Is this feature supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Yes Risks Interoperability and Compatibility Positive response from all members at W3C WebRTC WG April 2023 Interim, PR landed with no open issues. Ergonomics Added specifically to align with the timestamp field on the WebCodecs <https://www.w3.org/TR/webcodecs/#encodedvideochunk-interface> EncodedVideoChunk <https://www.w3.org/TR/webcodecs/#encodedvideochunk-interface>, and allow matching video frames with the timestamp in the WebCodecs VideoFrame <https://www.w3.org/TR/webcodecs/#videoframe-interface> object. Will also provide the same timestamp already exposed in requestVideoFrameCallback's 'mediaTime'. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/master/docs/testing/web_platform_tests.md> ? Tested internally by RTCEncodedVideoFrame-capture-timestamp-id.html <https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/web_tests/fast/peerconnection/RTCEncodedVideoFrame-capture-timestamp-id.html>, upstreaming to WPT tracked in crbug.com/1441888.
