您不能。

您不能以某人无法接收数据的方式发送数据。如果他们可以播放，则可以下载。动作相同。

You can't send someone data in a way that they can't receive the data. If they can play it, they can download it. It's the same action.

充其量，您可以使用唯一的标识符对媒体进行数字水印处理，以便在有人重新共享内容时可以对其进行追溯。您还可以通过使用签名的URL或一次性使用（或时间限制）的URL来防止他人共享媒体链接。

At best, you can digitally watermark your media with unique identifiers so that if someone re-shares the content, you can trace it back. You can also prevent someone from sharing a link to media by using signed URLs or otherwise one-time-use (or time-limited) URLs.
