ensureFfprobe()

Available from v3.3, removed from v4.0

warning

This API has been removed in v4.0 and is not necessary to call anymore. This page remains for archival purposes.

Checks if the ffprobe binary is installed and if it is not, downloads it and puts it into your node_modules folder.

ensure.mjs
ts
// @module: esnext
// @target: es2018
import { ensureFfprobe } from "@remotion/renderer";
await ensureFfprobe();
ensure.mjs
ts
// @module: esnext
// @target: es2018
import { ensureFfprobe } from "@remotion/renderer";
await ensureFfprobe();

You might not need to call this function. Remotion will automatically download ffprobe if a render is attempted, and no binary was found.

This function is useful if you need ffprobe to be ready before the first render is started.

Also call ensureFfmpeg() to get both binaries that Remotion requires.

Options​

Optionally, you can pass an object and pass the following options:

remotionRoot​

string

The directory in which your node_modules is located.

Return value​

A promise which resolves an object with the following properties:

  • wasAlreadyInstalled: Boolean whether the binary was downloaded because of this function call.
  • result: A string, either found-in-path, found-in-node-modules or installed.

Exceptions​

This function throws if no binary was found, the download fails or no binaries are available for your platform.
