Configuration (Vite+)

import { defineConfig } from "@vizejs/vite-plugin/vite-plus";

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "a11y/media-has-caption": "warn"
      }
    },
  },
});

vp run lint

Bad

The video has playback controls but no caption track.

<template>
  <video src="/demo.mp4" controls />
</template>

Good

A track with kind="captions" supplies the English captions for the same video.

<template>
  <video src="/demo.mp4" controls>
    <track kind="captions" src="/demo.en.vtt" srclang="en" label="English" />
  </video>
</template>

Good avoids this rule's finding under the configuration above; other rules may still report diagnostics.
