JavaScript@langchain/svelteuseVideoPlayer
Functionā—Since v1.0

useVideoPlayer

Bind a VideoMedia handle to a caller-owned <video> element.

Svelte idioms:

  • videoRef accepts a raw HTMLVideoElement, a $state binding, or a getter. Use Svelte 5's bind:this to assign a template reference and pass it via a getter so the composable re-binds when the element first mounts:
<script lang="ts">
  let videoEl = $state<HTMLVideoElement>();
  const player = useVideoPlayer(() => videoEl, () => media);
</script>
<video bind:this={videoEl} />
  • The composable never injects DOM nor overrides layout.
  • On component destroy (or when media changes) the composable calls media.revoke() to free the object URL.
