如何在NativeScript中实现音频和视频播放？

npm install nativescript-audio nativescript-video

import * as audio from "nativescript-audio";

let player = new audio.TNSPlayer();
player.initFromFile({
    audioFile: "~/audio.mp3",
    loop: false,
    completeCallback: function () {
        console.log("Playback completed");
    }
});

import * as video from "nativescript-video";

let player = new video.Video();
player.src = "https://example.com/video.mp4";
player.controls = true;
player.autoplay = false;

player.play();

player.play();

player.on(audio.AudioPlayerEvents.completeEvent, function () {
    console.log("Playback completed");
});

player.on(video.VideoPlayer.playbackCompleteEvent, function () {
    console.log("Playback completed");
});
