创建转换Create a transform
本文中的 Azure CLI 脚本演示如何创建转换。The Azure CLI script in this article shows how to create a transform. 转换描述了处理视频或音频文件的任务的简单工作流（通常称为“工作程序”）。Transforms describe a simple workflow of tasks for processing your video or audio files (often referred to as a "recipe"). 应始终检查具有所需名称和“工作程序”的转换是否已存在。You should always check if a Transform with desired name and "recipe" already exist. 如果已存在，应再次使用该转换。If it does, you should reuse it.
先决条件Prerequisites
创建媒体服务帐户。Create a Media Services account.
备注
只能为 StandardEncoderPreset 指定自定义标准编码器预设 JSON 文件的路径，请参阅使用自定义转换进行编码示例。You can only specify a path to a custom Standard Encoder preset JSON file for StandardEncoderPreset, see the encode with a custom transform example.
使用 BuiltInStandardEncoderPreset 时，不能传递文件名。You cannot pass a file name when using BuiltInStandardEncoderPreset.
