Enhances the YAML linter to validate scalar values against enum and pattern constraints defined in the schema. Adds utility functions for value comparison, schema constraint collection, and applies these checks during linting to provide more precise error messages for invalid values.
Browser support
ECMAScript 2019 (ES10) supported by iOS 12 (iPhone 5S, iPad Air, iPad Mini 2, etc.).
But ECMAScript 2017 (ES8) almost fine (es6 + async) and recommended for React+TypeScript.
Known problems
- Autoplay doesn't work for WebRTC in Safari read more.
HTML5
1. Autoplay video tag
Video auto play is not working
Recently many browsers can only autoplay the videos with sound off, so you'll need to add muted attribute to the video tag too
<video id="video" autoplay controls playsinline muted></video>
2. [Safari] pc.createOffer
Don't work in Desktop Safari:
pc.createOffer({offerToReceiveAudio: true, offerToReceiveVideo: true})
Should be replaced with:
pc.addTransceiver('video', {direction: 'recvonly'});
pc.addTransceiver('audio', {direction: 'recvonly'});
pc.createOffer();
3. pc.ontrack
TODO
pc.ontrack = ev => {
const video = document.getElementById('video');
// when audio track not exist in Chrome
if (ev.streams.length === 0) return;
// when audio track not exist in Firefox
if (ev.streams[0].id[0] === '{') return;
// when stream already init
if (video.srcObject !== null) return;
video.srcObject = ev.streams[0];
}
Chromecast 1
2023-02-02. Error:
InvalidStateError: Failed to execute 'addTransceiver' on 'RTCPeerConnection': This operation is only supported in 'unified-plan'. 'unified-plan' will become the default behavior in the future, but it is currently experimental. To try it out, construct the RTCPeerConnection with sdpSemantics:'unified-plan' present in the RTCConfiguration argument.
