getAudioDurationInSeconds()

@remotion/media-utils 包中的辅助函数之一。

之前称为 getAudioDuration()。

获取音频源的持续时间（以秒为单位）。Remotion 将创建一个不可见的 <audio> 标签，加载音频并返回持续时间。

参数

src

指向音频资产的字符串

返回值

Promise<number> - 音频文件的持续时间。

示例

tsx
import { getAudioDurationInSeconds } from "@remotion/media-utils";
import music from "./music.mp3";
 
const MyComp: React.FC = () => {
  const getDuration = useCallback(async () => {
    const publicFile = await getAudioDurationInSeconds(
      staticFile("voiceover.wav"),
    ); // 33.221
    const imported = await getAudioDurationInSeconds(music); // 127.452
    const remote = await getAudioDurationInSeconds(
      "https://example.com/remote-audio.aac",
    ); // 50.24
  }, []);
 
  useEffect(() => {
    getDuration();
  }, []);
 
  return null;
};
