mediaParserController()

warning

我们正在逐步淘汰 Media Parser，并转向使用 Mediabunny！

将 mediaParserController() 传递给 controller 以控制 parseMedia() 函数。

🌐 Pass mediaParserController() to controller to steer the parseMedia() function.

每个 mediaParserController 只能附加到 1 个 parseMedia() 调用。

🌐 Each mediaParserController can only be attached to 1 parseMedia() call.

Use mediaParserController()
import {mediaParserController, parseMedia} from '@remotion/media-parser';

const controller = mediaParserController();

parseMedia({
  src: 'https://www.w3schools.com/html/mov_bbb.mp4',
  controller,
});

// Pause
controller.pause();

// Resume
controller.resume();

// Abort
controller.abort();

应用编程接口​

🌐 API

此函数返回一个可以传递给 parseMedia({controller}) 的对象。

🌐 This function returns an object that can be passed to parseMedia({controller}).

它具有以下方法：

🌐 It has the following methods:

pause()​

暂停下载和解析过程。

🌐 Pauses the download and parsing process.

resume()​

恢复下载和解析过程。

🌐 Resumes the download and parsing process.

abort()​

中止下载和解析过程。

🌐 Aborts the download and parsing process.

seek(timeInSeconds: number)​

查找在你指定时间之前的最佳关键帧。

getSeekingHints()​

返回一个解析为 seeking hints 的 Promise。

🌐 Returns a promise that resolves to the seeking hints.

addEventListener()​

请参见下方的活动。

🌐 See events below.

removeEventListener()​

请参见下方的活动。

🌐 See events below.

事件​

🌐 Events

你可以将事件监听器附加到 mediaParserController() 返回的对象上。

🌐 You can attach event listeners to the object returned by mediaParserController().

Use events
import {mediaParserController, parseMedia} from '@remotion/media-parser';

const controller = mediaParserController();

const onPause = () => {
  console.log('Paused');
};

const onResume = () => {
  console.log('Resumed');
};

controller.addEventListener('pause', onPause);
controller.addEventListener('resume', onResume);

// Make sure to cleanup later:
controller.removeEventListener('pause', onPause);
controller.removeEventListener('resume', onResume);

它还会触发以下事件：

🌐 It also emits the following events:

pause​

当下载和解析过程被暂停时触发。

🌐 Emitted when the download and parsing process is paused.

resume​

当下载和解析过程恢复时发出。

🌐 Emitted when the download and parsing process is resumed.
