No video track found

Error message

No video track found

What it means

Example from the mediabunny get-video-dimensions rule: getPrimaryVideoTrack() on the opened Input returned no track, so displayWidth/displayHeight cannot be read. The supplied src is audio-only or otherwise has no primary video track.

Mediabunny can extract the width and height of a video file. It works in browser, Node.js, and Bun environments.

## Getting video dimensions

```tsx
import { Input, ALL_FORMATS, UrlSource } from "mediabunny";

export const getVideoDimensions = async (src: string) => {
  const input = new Input({
    formats: ALL_FORMATS,
    source: new UrlSource(src, {
      getRetryDelay: () => null,
    }),
  });

  const videoTrack = await input.getPrimaryVideoTrack();
  if (!videoTrack) {
    throw new Error("No video track found");
  }

  return {
    width: videoTrack.displayWidth,
    height: videoTrack.displayHeight,
  };
};
```

## Usage

```tsx
const dimensions = await getVideoDimensions("https://remotion.media/video.mp4");
console.log(dimensions.width);  // e.g. 1920
console.log(dimensions.height); // e.g. 1080
```

Solutions

1. Verify the file is a video before requesting dimensions
2. Fall back to probing with ffprobe when mediabunny finds no track
3. Throw a descriptive error naming the offending src so callers can filter inputs
