我正在尝试将 AWS Elemental MediaConvert 用于 AOD（点播音频）HLS 流。以下是我的职位描述

        "FileInput": "s3://kg-media-test/inputs/test_audio.mp4"
      }
    ]
}

但是，每当我将 MP3 文件作为输入时，它都会抛出错误 -

Exception: An error occurred (BadRequestException) when calling the CreateJob operation: /inputs/0/fileInput: 
Should match the pattern: /^(http|https|s3)://([^/]+/)+([^/\.]+|(([^/]*)\.([mM]2[vV]|[mM][pP][eE][gG]|[aA][vV][iI]|[mM][pP]4|[fF][lL][vV]|[mM][pP][tT]|[mM][pP][gG]|[mM]4[vV]|[tT][rR][pP]|[fF]4[vV]|[mM]2[tT][sS]|[tT][sS]|264|[hH]264|[mM][kK][vV]|[mM][oO][vV]|[mM][tT][sS]|[mM]2[tT]|[wW][mM][vV]|[aA][sS][fF]|[vV][oO][bB]|3[gG][pP]|3[gG][pP][pP]|[mM][xX][fF]|[dD][iI][vV][xX]|[xX][vV][iI][dD]|[rR][aA][wW]|[dD][vV]|[gG][xX][fF]|[mM]1[vV]|3[gG]2|[vV][mM][fF]|[mM]3[uU]8|[wW][eE][bB][mM]|[lL][cC][hH]|[gG][xX][fF]_[mM][pP][eE][gG]2|[mM][xX][fF]_[mM][pP][eE][gG]2|[mM][xX][fF][hH][dD]|[wW][aA][vV]|[yY]4[mM]|[xX][mM][lL])))$/

看起来对输入文件名进行了正则表达式验证，并且不允许使用 MP3 文件。但是根据这个文档，MP3 是一个有效的输入文件。

如果我将该 MP3 文件转换为 MP4 文件然后尝试，那么该作业将生成 HLS，而不会出现任何错误。

我在这里缺少什么？

这当然很晚了，但你的 json 有这个。

"Destination": "s3://<MEDIABUCKET>/HLS/",

这可能是你的问题。
