ensureFfprobe()v3.3

@remotion/renderer包的一部分。 从v4.0中移除

🌐 Part of the @remotion/renderer package. Removed from v4.0

warning

此 API 在 v4.0 中已被删除，不再需要调用。本页面保留用于存档目的。

检查是否已安装 ffprobe 二进制文件，如果未安装，下载它并将其放入你的 node_modules 文件夹。

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

ensure.mjs
import {ensureFfprobe} from '@remotion/renderer';

await ensureFfprobe();

你可能不需要调用此函数。如果尝试渲染且未找到二进制文件，Remotion 将会自动下载 ffprobe。

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

如果你需要在第一次渲染开始之前准备好 ffprobe，这个函数非常有用。

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

还调用 ensureFfmpeg() 来获取 Remotion 所需的两个二进制文件。

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