我正在尝试使用AWS Elemental MediaConvert进行AOD(音频点播)HLS流传输。以下是我的职位描述

      }
    ]
}

但是,每当我提供MP3文件作为输入时,它就会抛出错误-

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])))$/

似乎输入文件名上有一个正则表达式验证,并且不允许MP3文件。但是根据this文档,MP3是有效的输入文件。

如果我将MP3文件转换为MP4文件,然后尝试运行,则作业正在生成HLS,而没有任何错误。

我在这里想念什么?

这当然很晚了,但是您的json有这个。

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

这可能是您的问题。
