According to the MediaInfo ChangeLog, Amazon S3 support was added in v0.7.76 and even patched in v0.7.77 (latest).
However, I can't find any documentation on how to implement it. It's not in CLI help menu nor the SourceForge project pages. I was hoping someone here might have some insight as the SourceForge forum is closed off.
How do I craft a MediaInfo command to use Amazon S3 with Access Key & Secret Key? I'm using the CLI.
The closest thing I could find was someone's example Java code: http://fossies.org/linux/MediaInfo_CLI/MediaInfoLib/Source/Example/HowToUse_Dll.JNA.java
It looks like they're crafting a custom HTTP request to S3 and streaming the response to MediaInfo. I'm not sure. I don't know Java; I only know Bash, Ruby, PHP.
Has anyone successfully got MediaInfo working with S3; something like this?
mediainfo https://AWSAccessKeyId:[email protected]/bucketname/filename

X-Ray enables trace messages for Amazon S3 event notifications. You can use the X-Ray service map to view the connections between Amazon S3 and other services that your application uses. You can also use the console to view metrics such as average latency and failure rates.
Amazon S3 Select and Amazon S3 Glacier Select enable customers to run structured query language SQL queries directly on data stored in S3 and Amazon S3 Glacier. With S3 Select, you simply store your data on S3 and query using SQL statements to filter the contents of S3 objects, retrieving only the data that you need.
You can set whole buckets to certain TTL using the S3 Browser tool , the link is also a guide to setting bucket wide TTL.
The Lambda function retrieves the source S3 bucket name and the key name of the uploaded object from the event parameter that it receives. The function uses the Amazon S3 getObject API to retrieve the content type of the object.
The Java example is an example about how to download with Java and send data to MediaInfo from Memory. Now MediaInfo has native support of S3. So just provide this URL.
The only issue is that you must have libcurl available and MediaInfo compiled with libcurl support. This is not already available on all platforms (e.g. on Windows you must put libcurl.dll from libcurl website in the same folder as mediainfo).
Better delivery of such support (with libcurl provided directly, and fully tested, on all platforms) is planned but there is no ETA.

Mediainfo executable can be built with libcurl on linux distribution using below commands: (I used centos)
yum groupinstall 'Development Tools'
yum install libcurl-devel
yum install wget
wget http://mediaarea.net/download/binary/mediainfo/17.12/MediaInfo_CLI_17.12_GNU_FromSource.tar.xz
tar xvf MediaInfo_CLI_17.12_GNU_FromSource.tar.xz
cd MediaInfo_CLI_GNU_FromSource/
./CLI_Compile.sh --with-libcurl
cd MediaInfo/Project/GNU/CLI
./mediainfo --version
Then following command will provide media information for Amazon S3 url.
mediainfo --Output=XML https://AWSAccessKeyId:[email protected]/bucketname/filename
The above command won't work with AWS keys(filename) having special characters. By using pre-signed url, it is possible to use special characters in AWS Keys.
aws s3 presign 's3://bucketname/testing/mini & bar™©.mp4'
mediainfo 'presignd url'
