Like all good boys should.

Could you add an example or description how to enumerate the fields which were found in a file?

At least there seems to be no common directory of tags which can exist, or does it?

Hi, I'm getting an exception trying to convert data to JSON format

mi = Mediainfo.new '/tmp/sample.mp4'
puts mi.to_json

ActiveSupport::JSON::Encoding::CircularReferenceError: object references itself

thanks

I have mediainfo installed:

$ which mediainfo
/usr/bin/mediainfo
$ /usr/bin/env mediainfo --version
MediaInfo Command line,
MediaInfoLib - v0.7.82

However the gem is looking for it in the wrong place:

irb(main):004:0> media_info = MediaInfo.from('./bad-video-hikvision.mkv')
Traceback (most recent call last):
        5: from /usr/bin/irb:11:in `<main>'

MediaInfo::EnvironmentError (/usr/local/bin/mediainfo cannot be found. Are you sure mediainfo is installed?)

It would be good if it would find it using /usr/bin/env and only fallback to the hardcoded path.

This

      def self.standardize_to_milliseconds(value)
        return standardize_float_to_milliseconds(value.to_f) if value.to_f.to_s == value.to_s
        return standardize_string_to_milliseconds(value)
        value
      end

doesn't work if value has a trailing zero (e.g. 123.450) and it will return a string instead of an integer.

Here's a suggested fix:

   return standardize_float_to_milliseconds(value.to_f) if value =~ /^\d+\.?\d*$/

with MediaInfoLib - v21.09, the command to generate output as XML seems to remove dashes from elements' names :

mediainfo <file> --Output=XML

<extra>
<WAVELISTYEAR>2020</WAVELISTYEAR>
</extra>

with MediaInfoLib - v22.09, the command returns elements' names with dashes :

mediainfo <file> --Output=XML

<extra>
<WAVELIST-YEAR>2020</WAVELIST-YEAR>
</extra>

This is causing issue with MediaInfo.from(<filepath>) :

NameError (`@wavelist-year' is not allowed as an instance variable name)

Hello,

I've just downloaded this gem and everything was great until I started experimented with the video's properties.

When I executed the following code I got a nasty expection:
begin
info = Mediainfo.new destination_file_path
self.duration = info.video.duration
rescue
logger.fatal "Unable to access Video Info through MediaInfo CLI!\n$!"
return false
end

Abort trap

For some reason that yield is causing ruby to blowup. Any help would be appreciated :)

MediaInfo.from('/some/path/some-file-name-with-colon:like-this.txt') will internally call MediaInfo.from_link instead of MediaInfo.from_local_file.

I'm getting this when I try to use a filename:

irb(main):003:0> media_info = MediaInfo.from('bad-video-hikvision.mkv')
Traceback (most recent call last):
        3: from /usr/bin/irb:11:in `<main>'
        2: from (irb):3
        1: from /var/lib/gems/2.5.0/gems/mediainfo-1.0.1/lib/mediainfo.rb:84:in `from'
ArgumentError (Bad Input)
Input must be:
A video or xml file location. Example: '~/videos/test_video.mov' or '~/videos/test_video.xml'
A valid URL. Example: 'http://www.site.com/videofile.mov'
Or MediaInfo XML

However, this works:

irb(main):004:0> media_info = MediaInfo.from('./bad-video-hikvision.mkv')

It would be good if a filename can be provided without ./

Hi trying to get the mediainfo of a file on AWS S3 using a signed URL (code shown below) but am getting the error

MediaInfo::RemoteUrlError: HTTP call to xxxxxxxx is not working!.

I know the URL is accessible because I can access it through a browser (it initiates a download). Also, I think it should work since the mediainfo command line (MediaInfoLib - v18.12) works and returns the JSON, using this command:

mediainfo --Output=JSON https://eu-west-1-xxxxxxx

Here's what I'm doing with Ruby

s3_resource = Aws::S3::Resource.new(region: AWS_REGION)
obj = s3_resource.bucket(BUCKET_NAME).object(s3_name)

signed_url = obj.presigned_url(:get, expires_in: 3600)

media_info = MediaInfo.from(signed_url)

the result is

MediaInfo::RemoteUrlError: HTTP call to xxxxxxxx is not working!

I'm using mediainfo gem (1.1.2), aws-sdk (2.11.58) and ruby-2.3.1 if it helps at all

This, of course, blows up.

Hello,
we encountered some issues with the MediaInfo.from(file. path)
files submitted by our users have all zeros as an encoding date

Could MediaInfo handle the encoding date if it's not able to be parsed instead of throwing the error:

ArgumentError: mon out of range

This seems to be an edge case for some video files.
When the metadata info 'tracks' XML element is empty, this code will blow up:
https://github.com/greatseth/mediainfo/blob/1eb021d8018a37b0cd3604d55c17a3e7a1eef56c/lib/mediainfo/tracks.rb#L40 since ::REXML::Element#text, i.e.: parameter.text will return nil.

mediainfo seems to be throwing the wrong exception when receiving an invalid method. I typoed .video.bit_rate_mode as .video.bitrate_mode; however, the exception raised received was:

Mediainfo::StreamProxy::NoStreamsForProxyError: there are no :video streams to send :bitrate_mode to

That made me scratch my head for awhile, because the video does have a video stream. I think a different exception should be raised in this instance.

Since those are both free for open source projects, could we add :

• a CI service (such as https://travis-ci.org) in order to run specs automatically every time a PR is submitted.
• CodeClimate (with Rubocop) in order to easily improve & keep an eye on the code maintainability and complexity, and the tests coverage.

I don't have the right on this repo myself to "PR" these integrations.
I would be okay to improve the code based on CodeClimate's & Rubocop's advices for maximum availability if you are ok with integrating those.

Although we set the path by using MEDIAINFO_PATH, there is a check on the .location method where it tries which('mediainfo') no matter what.

So, even though we specified the custom path, it tries to find the original one from PATH.

My use case is a Lambda function, so I won't change the original PATH, but rather use the mediainfo binary located in my project.

Hi,

the command line version of mediainfo can (at least for some videos) give details about the language for audio and subtitle tracks, like

Language : English

The gem, however, doesn't seem to support this. Would be nice.

Hi,

mediainfo issues the following section for videos with a timecode, e.g. from a GoPro:

I wanted to inform you about a "backward incompatibility" with the latest version of the MediaInfo CLI and the latest version of this Gem.
The CLI version [MediaInfo Command line, MediaInfoLib - v0.7.82] works with the 0.7.2 gem.
But with CLI version [MediaInfo Command line, MediaInfoLib - v0.7.95] intalled, when querying a WAVE file's duration from the gem, the following error is thrown:
/Library/Ruby/Gems/2.0.0/gems/mediainfo-0.7.2/lib/mediainfo/attr_readers.rb:60:in block (2 levels) in mediainfo_duration_reader': unexpected time fragment! please report bug! (RuntimeError) from /Library/Ruby/Gems/2.0.0/gems/mediainfo-0.7.2/lib/mediainfo/attr_readers.rb:51:in each'

It's showing wrong duration info. For a video of 6 seconds its showing 5700 seconds

It seems that timezone information of date fields are not properly parsed, because Time.parse does not understand the prefix "UTC" in the date strings. It just ignores it and returns a local time.

Ways to reproduce

require 'mediainfo'
require 'active_support/core_ext/hash'
    
source = .... # Your file here
mi = MediaInfo.from(source)
    
puts "Returned from MediaInfo: #{mi.general.encoded_date}"
    
xmldate = Hash.from_xml(mi.xml)["MediaInfo"]["media"]["track"][0]["Encoded_Date"]
    
puts "Raw date from MediaInfo xml: #{xmldate}"
puts "Time parse directly on xmldate: #{Time.parse(xmldate)}"
puts "Time parse with UTC correction: #{Time.parse(xmldate.gsub("UTC\s+", '') + " UTC").localtime}"

This will return (for one example):

Returned from MediaInfo: 2017-08-09 23:08:00 +0200 -> Wrong
Raw date from MediaInfo xml: UTC 2017-08-09 23:08:00 -> This is what is in the file.
Time parse directly on xmldate: 2017-08-09 23:08:00 +0200 -> Wrong
Time parse with UTC correction: 2017-08-10 01:08:00 +0200 -> This should be returned

I just noticed this, because I was checking filenames (which included dates) against metadata using MediaInfo gem and because I am in UTC+2 there was this file where there was a different date returned by MediaInfo compared to the filename.

I'm using the latest version of the gem and MediaInfo v17.12. When using mediainfo directly, it works and identifies the multiple streams and that this is a video:

=> #<Mediainfo:0x00007fd93304b938 @streams=[], @full_filename="/Volumes/MyBook/test.mp4", @path="/Volumes/MyBook/", @filename="test.mp4", @escaped_full_filename="\"/Volumes/MyBook/test.mp4\"", @last_command="mediainfo \"/Volumes/MyBook/test.mp4\" --Output=XML", @raw_response="...", @general_stream=#<Mediainfo::GeneralStream:0x00007fd93393d488 @stream_type=:general, @parsed_response={:general=>{}}>, @video_stream=#<Mediainfo::VideoStream:0x00007fd93393d208 @stream_type=:video, @parsed_response={:video=>{}}>, @audio_stream=#<Mediainfo::AudioStream:0x00007fd93393cf88 @stream_type=:audio, @parsed_response={:audio=>{}}>, @image_stream=#<Mediainfo::ImageStream:0x00007fd93393cd08 @stream_type=:image, @parsed_response={:image=>{}}>, @menu_stream=#<Mediainfo::MenuStream:0x00007fd93393ca88 @stream_type=:menu, @parsed_response={:menu=>{}}>, @text_stream=#<Mediainfo::TextStream:0x00007fd93393c808 @stream_type=:text, @parsed_response={:text=>{}}>>
irb(main):016:0> info.video?
=> false
irb(main):017:0> info.streams
=> []

Any ideas?
