AWS Elemental MediaConvert 视频文件修剪开始和结束持续时间

如何解决AWS Elemental MediaConvert 视频文件修剪开始和结束持续时间

只是想知道当用户通过 JavaScript 上传视频文件时我如何处理来自 AWS Elemental MediaConvert 的视频修剪

解决方法

MediaConvert 要求您将 SDK 设置为使用特定的 API 输入 [1,2]

JavaScript SDK 文档 [3] 说明了如何使用 JS SDK 在 MeidaConvert 中定义和创建作业。为了完成输入剪辑，您需要将 InputClippings 选项添加到 Input JSON 块。示例如下：

"Inputs": [
      {
        "AudioSelectors": {
          "Audio Selector 1": {
            "Offset": 0,"DefaultSelection": "NOT_DEFAULT","ProgramSelection": 1,"SelectorType": "TRACK","Tracks": [
              1
            ]
          }
        },"VideoSelector": {
          "ColorSpace": "FOLLOW"
        },"FilterEnable": "AUTO","PsiControl": "USE_PSI","FilterStrength": 0,"DeblockFilter": "DISABLED","DenoiseFilter": "DISABLED","TimecodeSource": "ZEROBASED","FileInput": "s3://INPUT_BUCKET_AND_FILE_NAME","InputClippings": [
          {
            "StartTimecode": "00:00:00:00","EndTimecode": "00:05:00:00"
          }
        ]
      }
    ]

请记住，TimecodeSource 会影响剪切区域。如果您知道您的用户上传的源文件包含嵌入的时间码，您可以将其更改为 EMBEDDED，有关详细信息，请参阅文档 [4]
