我在mac上安装了mediainfo工具。我可以用它看本地视频文件。但是当我看到有关aws s3上哪个文件的信息时,我收到了一个错误:
$ mediainfo "https://bucket-name.s3.amazonaws.com/my/folder/my-video.wmv\?AWSAccessKeyId\=MyKeyId\&Expires\=298838448\&Signature\=sf389h94nvshgohwogwdn"
E: https://bucket-name.s3.amazonaws.com/my/folder/my-video.wmv\?AWSAccessKeyId\=MyKeyId\&Expires\=298838448\&Signature\=sf389h94nvshgohwogwdn, <?xml version="1.0" encoding="UTF-8"?>
<Error><Code>AccessDenied</Code><Message>Access Denied</Message> <RequestId>FOI2IFNFEFI3F</RequestId><HostId>ofoiheoHAOI3hf2048hHlhfhldnlsx9ajldkfahssflflweiwf3ivnv</HostId></Error>
我可以从公共网址访问该视频,但为什么无法从mediainfo
访问?
