我试图用AWS Elastic Transcoder CLI缝合两个片段，但我遇到了错误。
我的命令：aws elastictranscoder create-job --pipeline-id 158182938949-p2e73l --inputs Key=movie1.mp4,movie2.mp4 --outputs Key=complete-mov.mp4,PresetId=159474848914704-fupili,Watermarks=[{PresetWatermarkId=TopLeft,InputKey=Untitled-4png.png}]
我得到这个错误：
参数验证失败：参数Inputs[0]的类型无效。键，值：['MEYD-001.mp4'，'intro.mp4']，类型：<类"列表">，有效类型：<类"str">
如何在AWS Elastic转码器CLI中添加多个输入[视频]？AWS文档缺少这一点。
谨致问候。
@akamai-我错了。ET允许您在一次操作中缝合夹子。我认为您的问题是使用快捷方式语法而不传递JSON数组。
尝试从更新您的命令
Key=movie1.mp4,movie2.mp4
至
'[{"Key"="movie1.mp4"},{"Key"="movie2.mp4"}]'
您可能需要一些额外的参数来获得所需的结果。您可以使用AWS命令生成一个模板来指导您，如下所示：aws elastictranscoder create-job --generate-cli-skeleton。这将输出一个JSON字符串，其中包含命令的每个可用属性。如果您查看下面的输入部分，它被定义为一个数组："Inputs": [。
myname@mypc:~$ aws elastictranscoder create-job --generate-cli-skeleton
