用于MPEG-DASH转码的AWS Lambda

Question

我有点困惑。我正在设置一个lambda，用于将MP4代码转换为MPEG-Dash以进行自适应流传输。

这里有4份礼物

MPEG-DASH Video 600 k  1351620000001-500050
MPEG-DASH Video 1200 k 1351620000001-500040
MPEG-DASH Video 2400 k 1351620000001-500030
MPEG-DASH Video 4800 k 1351620000001-500020

我遵循了这个example，作者似乎通过管道创建了4个输出和一个播放列表。

我正在尝试解决如何在createJob函数中设置它。

transcoder.createJob({
     PipelineId: process.env.PIPELINE_ID,
     Input: {
      Key: srcKey,
      FrameRate: 'auto',
      Resolution: 'auto',
      AspectRatio: 'auto',
      Interlaced: 'auto',
      Container: 'auto'
     },
     Output: {
      Key: id + '_4m.mpd',
      ThumbnailPattern: '',
      PresetId: '1351620000001-500020',
      Rotate: 'auto'
     }
    }, function(err, data){
        if(err){
            console.log('Something went wrong:',err)
        }else{
            console.log('Converting is done');
        }
     callback(err, data);
    });
};

这里只有一个输出，没有播放列表。

谁能解释一下我需要什么自适应流，即我假设所有的输出和播放列表文件？

这似乎行得通

Outputs: 
[
    {
        Key: 'dash/' + id + '_audio.fmp4',
        PresetId: '1351620000001-500060',
        SegmentDuration: '3',
        Watermarks: [],
        Composition: [],
    }, 
    {
        Key: 'dash/' + id + '_600k.fmp4',
        PresetId: '1351620000001-500050',
        SegmentDuration: '3',
        Watermarks: [],
        Composition: [],
    }, 
    {
        Key: 'dash/' + id + '_1200k.fmp4',
        PresetId: '1351620000001-500040',
        SegmentDuration: '3',

Playlists:

        ],
    }, 
],
