Media::Info - Return information on media file/URL
This document describes version 0.133 of Media::Info (from Perl distribution Media-Info), released on 2020-07-29.
use Media::Info qw(get_media_info); my $res = get_media_info(media => '/path/to/celine.mp4');
Sample result:
[ 200, "OK", { audio_bitrate => 128000, audio_format => 85, audio_rate => 44100, duration => 2081.25, num_channels => 2, num_chapters => 0, }, { "func.raw_output" => "ID_AUDIO_ID=0\n...", }, ]
This module provides a common interface for Media::Info::* modules, which you can use to get information about a media file (like video, music, etc) using specific backends. Currently the available backends include Media::Info::Mplayer, Media::Info::Ffmpeg, Media::Info::Mediainfo.
Usage:
get_media_info(%args) -> [status, msg, payload, meta]
Return information on media file/URL.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
backend => str
Choose specific backend.
media* => str
Media file/URL.
Note that not every backend can retrieve URL. At the time of this writing, only the Mplayer backend can.
Many fields will depend on the backend used. Common fields returned include:
backend: the Media::Info::* backend module used, e.g. Ffmpeg.
backend
Media::Info::*
Ffmpeg
type_from_name: either image, audio, video, or unknown. This is determined from filename (extension).
type_from_name
image
audio
video
unknown
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)

Video::Info - Media::Info is first written because I couldn't install Video::Info. That module doesn't seem maintained (last release is in 2003 at the time of this writing), plus I want a per-backend namespace organization instead of per-format one, and a simple functional interface instead of OO interface.
