使用videojs-ima插件捆绑videojs

Posted 2021-05-04

我正在尝试（已经很短的几天）来完成非常简单的任务：构建一个javascript文件捆绑所有必要的部分来播放视频与谷歌IMA广告，但我仍然面临一些错误（主要是player.ads is not function）总是以某种方式连接到错误注册插件。我很感激任何建议。谢谢。

编辑：这个问题是already reported，但标记为优先级3，我没有时间等待。我相信还有另一种解决方案。

编辑2：似乎在上面链接中报告此问题的人已经提供了合适的解决方案。现在它仍然只是尝试它..如果它会工作，我发布它作为答案。

他打破了：

/*jshint esversion: 6 */
/*jshint -W030 */

let ima_script = document.createElement('script');
ima_script.type = "text/javascript";
ima_script.src = "https://imasdk.googleapis.com/js/sdkloader/ima3.js";
document.getElementsByTagName('head')[0].appendChild(ima_script);

videojs = require('video.js');
require('videojs-contrib-ads');
require('videojs-ima');
require('videojs-youtube');
require('videojs-contrib-hls');

Array.from(document.getElementsByTagName('video'))
    .forEach(videojs);

ima_script.onload = function() {
    google.ima.settings.setLocale('cs');
    let players = videojs.players;
    for (let id in players) {
        (players.hasOwnProperty(id) ? players[id].ima({
            id: id,
            adTagUrl: 'https://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/single_ad_samples&ciu_szs=300x250&impl=s&gdfp_req=1&env=vp&output=vast&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ct%3Dlinear&correlator=',
            disableFlashAds: true
        }):'');
    }
};

gulp.task('clean', function (done) {

  done();

gulp.task('lintjs', function() {

gulp.task('build-bundle', function () {
  var videoJS = browserify({
      entries: 'src/entryfile.js',
      //debug: true,
      paths: ['./node_modules'],

      packageCache: {}
    })
    .transform(babelify)
    .bundle()
    .pipe(source('outputfile.js'))
    .pipe(buffer());

  var videoCss = gulp.src('node_modules/video.js/dist/video-js.css')
    .pipe(cssnano())
    .pipe(css2js());

  var imaCss = gulp.src('node_modules/video-ima/dist/videojs.ima.css')
    .pipe(cssnano())
    .pipe(css2js());

  return mergeStream(videoCss, imaCss, videoJS)
    .pipe(concat('video.bundle.js'))
    /*
    .pipe(sourcemaps.init({loadMaps: true}))
    .pipe(uglify({compress: false})) // compress needs to be false otherwise it mess the sourcemaps
    .pipe(sourcemaps.write('.'))*/
    .pipe(gulp.dest(distPath))
    .pipe(size({showFiles: true, title: '[VideoJS+Plugin Bundle]'}));
});

答案

根据EDIT2，这只是修改，使其工作：

修改需要部​​分Entryfile：

videojs = require('video.js');
var contribAds = require('videojs-contrib-ads');
videojs.registerPlugin('ads', contribAds);
require('video.js/dist/lang/cs.js')
require('videojs-youtube');
require('videojs-contrib-hls');
require('videojs-ima');

编辑

注册contrib-ads插件在v6中已“修复”。现在你应该简单地使用：

require('videojs-contrib-ads');
