This commit refactors the log handling in the API to use a switch statement for improved readability and maintainability. It also introduces error messages with more context when reading or truncating the log file fails. On the frontend, a new auto-update toggle button has been added to the log viewer, allowing users to enable or disable automatic log updates. The button's appearance changes based on its state, providing a clear visual indication of whether auto-update is active. Additionally, the button styling has been updated to ensure consistency across the interface.
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.
