@akamai - i was wrong. @akamai - 我错了。 ET does allow you to stitch clips in a single operation. ET确实允许您在一次操作中缝合剪辑。 I think your issue is your using the shortcut syntax and not passing a JSON array.我认为您的问题是您使用快捷语法而不是传递 JSON 数组。
Try updating your command from尝试从更新您的命令
Key=movie1.mp4,movie2.mp4
to至
'[{"Key"="movie1.mp4"},{"Key"="movie2.mp4"}]'
You may need some additional parameters to get the desired result.您可能需要一些额外的参数来获得所需的结果。 You can use the AWS command to generate a template to guide you like this: aws elastictranscoder create-job --generate-cli-skeleton .您可以使用 AWS 命令生成模板来指导您，如下所示： aws elastictranscoder create-job --generate-cli-skeleton 。 That will output a JSON string with every available property of the command.这将 output 一个 JSON 字符串与命令的每个可用属性。 If you look at the Inputs section below, its defined as an array: "Inputs": [ .如果您查看下面的 Inputs 部分，它被定义为一个数组： "Inputs": [ 。
