windows - 使用 puppeteer、windows 在 chromium 中播放 mp4

Question

我正在 Windows 10 上的节点中使用 puppeteer 进行开发。问题是当我打开一个播放 mp4 文件的网站时，浏览器告诉我它不受支持。

我找到了这个包:chromium-codecs-ffmpeg-nonfree ;但它适用于 Linux!

如何在 Windows 上使用 puppeteer 在 Chromium 中播放 .mp4？

Puppeteer Documentation对此有一个答案:

Q: What features does Puppeteer not support?

You may find that Puppeteer does not behave as expected when controlling pages that incorporate audio and video. (For example, video playback/screenshots is likely to fail.) There are two reasons for this:

• Puppeteer is bundled with Chromium--not Chrome--and so by default, it inherits all of Chromium's media-related limitations. This means that Puppeteer does not support licensed formats such as AAC or H.264. (However, it is possible to force Puppeteer to use a separately-installed version Chrome instead of Chromium via the executablePath option to puppeteer.launch. You should only use this configuration if you need an official release of Chrome that supports these media formats.)
• Since Puppeteer (in all configurations) controls a desktop version of Chromium/Chrome, features that are only supported by the mobile version of Chrome are not supported. This means that Puppeteer does not support HTTP Live Streaming (HLS).

因此，为了在 Puppeteer 中截取视频播放，您需要将 executablePath 设置为单独安装的 Chrome 可执行文件:

const browser = await puppeteer.launch({
  executablePath: '/path/to/Chrome',
});
