App::MediaInfo - Utilities related to getting (metadata) information
from media files
VERSION
This document describes version 0.126 of App::MediaInfo (from Perl
distribution App-MediaInfo), released on 2020-05-30.
FUNCTIONS
media_info
Usage:
media_info(%args) -> [status, msg, payload, meta]
Get information about media files/URLs.
Many fields will depend on the backend used. Some other fields returned:
* "info_backend": the "Media::Info::*" backend module used, e.g.
"Ffmpeg".
* "type_from_name": either "image", "audio", "video", or "unknown".
This is determined from filename (extension).
This function is not exported.
Arguments ('*' denotes required arguments):
* backend => *str*
Choose a specific backend.
* media* => *array[filename]*
Media files/URLs.
Returns an enveloped result (an array).
First element (status) is an integer containing HTTP status code (200
means OK, 4xx caller error, 5xx function error). Second element (msg) is
a string containing error message, or 'OK' if status is 200. Third
element (payload) is optional, the actual result. Fourth element (meta)
is called result metadata and is optional, a hash that contains extra
information.
Return value: (any)
media_is_landscape
Usage:
media_is_landscape(%args) -> [status, msg, payload, meta]
Return exit code 0 if media is landscape.
Portrait is defined as having 'rotate' metadata of 90 or 270. Otherwise,
media is assumed to be 'landscape'.
This function is not exported.
Arguments ('*' denotes required arguments):

Media file/URL.
* quiet => *true*
Don't output anything on command-line, just return appropriate exit
