In this Media & Entertainment IG meeting, Yuhao Fu at Bytedance will introduce two video related API proposals. Media WG members are invited to join, we value your feedback on these proposals:
video.requestVideoLoadCallback() - a proposal to allow web developers to get response information such as video data, HTTP code, error details, and so on when using <video src="{file address}"> for media playback. See https://github.com/leonardoFu/video-rvlc/blob/main/explainer.md
<video> SEI events - a proposal to expose h.264 SEI (Supplemental Enhancement Information) events to synchronize interactivity with live video. See https://github.com/leonardoFu/video-sei-event/blob/main/explainer.md

This time, we have a number of issues related to MSE, and in particular MSE in Workers:
w3c/media-source#184 MSE for WebCodecs (comment). See explainer: https://github.com/wolenetz/mse-for-webcodecs/blob/main/explainer.md - wolenetz
Explainer describes supporting buffering containerless WebCodecs encoded media chunks with MSE for low-latency buffering and seekable playback.
The extended HTML AudioTrack, VideoTrack, TextTrack, and their *TrackList IDLs need updating to have exposure to both Window and DedicatedWorker, not just Window.
Should HTMLMediaElement do any error transition upon the termination of the DedicatedWorkerGlobalScope that owns the attached MediaSource?
w3c/media-source#275 Consider relaxing timing of initial HAVE_METADATA transitioning - wolenetz
There is inconsistent behaviour between implementations in the updateend event associated with an appendBuffer() whose parsing causes a HAVE_METADATA state transition.
w3c/media-source#281 MSE-in-Workers: Track enable/selection change behavior needs clarity - wolenetz
What to do with selected/enabled track state management if MSE is in a DedicatedWorker, while the HTMLMediaElement remains in Window?
