Converting an AVI video to a MP4 video:

|
|
|
```js
|
|
import { FFmpeg } from "@ffmpeg/ffmpeg";
|
|
import { fetchFile } from "@ffmpeg/util";
|
|
|
|
const videoURL = "https://github.com/ffmpegwasm/testdata/raw/master/video-15s.avi";
|
|
|
|
(async () => {
|
|
const ffmpeg = new FFmpeg();
|
|
// Create a web worker and the worker loads WebAssembly code.
|
|
await ffmpeg.load();
|
|
// Write a video file to FS.
|
|
await ffmpeg.writeFile("input.avi", await fetchFile(videoURL));
|
|
// Execute ffmpeg command.
|
|
await ffmpeg.exec(["-i", "input.avi", "output.mp4"]);
|
|
// Read the output video file from FS, the output file is a Uint8Array typed
|
|
// array.
|
|
const data = await ffmpeg.readFile("output.mp4");
|
|
})();
