What is it

Avdump is a video codec identification utility - identifies which video codec and audio compression method is used on video files. Furthermore it calculates the used bitrates, the length, identifies the number of used audiochannel and more.
It is mainly based on mediainfo, but got enhanced and changed to fit anidb's needs by epoximator.
Avdump was created with the intention to provide anidb with a tool to standarize the input. Furthermore it will become part of the upcoming AOM 0.6 allowing to autocreq all the generated informations.

Supported formats

  • avi, mkv, ogm, mp4, asf/wmv, mpg, rm, mov

Known issues

Note: Avdump is under development. Don't take the validity of its output for granted. Please report errors/issues.

  • Audio channel detection is very simple:
    • Number of channels might be wrong. (5.1 vs 6.1, 6.1 vs 7.1)
    • No check of actual data in channels. (dummy channels)
  • No detection of fps for asf/wmv files.
  • No detection of video anamorphism in mp4.
  • Not full parsing of mp4/mpg/mov/rm/asf/etc.
  • Avdump is only for Windows at the moment. It works via Wine though.
  • More...

Usage

Avdump is a simple commandline client and as that is to be used in the dosbox:

avdump [-ext:<extensions>] [-log:<log file>] <media file/folder> [<media file/folder> ...]

Options: (one letter switches can be put in one string)
Input: (all requires :)
   ext      comma separated extension list
   log      write output to file
   exp      export ed2k-links to file
   ac       autocreq: '-ac:<username>:<apipass>'
   port     udp port used by ac
   done     save processed-file-paths to file and exlude existing from proc
   bsize    buffer size for hashing in KB (2048 is default)
   tout     timeout: '-tout:<seconds>:<number of retries>'
 Output: (exclusive)
   s        Short (creq friendly)
   l        List (codecs)
   x        XML Old format
   y        XML Creq format
 Control:
   c        do _not_ reCurse into subfolders
   i        skIp full parsing (only for testing)
   m        Monitor folder(s)
   n        add extra Newline after each file
   p        Pause when done (hold cmd window)
   q        pause after each file
   r        Random file order
   t        print Time used for each file
   z        delete files after parsing
   o        wait for respOnse when sending dumps and retry on timeout
 Hash:
   0        crc32
   1        ed2k
   2        md5
   3        sha1
   5        tth
   6        aich
   9        mp3 w/o metadata (test)
   a        All hash algorithms
   h        Hash mode (no a/v parsing)
   e        print Ed2k link
   d        print aniDb link
   g        print and Goto anidb link
   u        print time Used

Alternative way of usage

  • Extract to a folder of choice
  • Right-click avdump.exe, select "Create Shortcut"
  • Right-click the shortcut, add " -p" to the "Shortcut - Target" line
Example: "C:\program files\Codecs\avdump\avdump.exe" -p
Optional: Change "Run" to "Maximized"
you can also set other options like s, x or t if you wish to do so.
  • Move shortcut to C:\Documents and Settings\[Username]\SendTo
[Username] is your WinXP LogIn-Name
SendTo is a hidden folder
  • Right-click any media-file, goto "Send To", choose avdump (or whatever you called the shortcut)
  • Be happy :D
  • Get CReqing

Processing DVD's

For processing DVD's it's best to set a small blocksize. Helps to improve performance.

something like

-bsize:256

(default is 2048)

A simple GUI for Avdump2 is available for CLI skeptics. The GUI package includes the most recent version of Avdump2 as well.

Screenshot of the AVDump2 GUI

Usage

  1. Download the GUI here (portable).
  2. Set your AniDB user name and API password in the options menu.
    1. API password is set on your user settings page: http://anidb.net/perl-bin/animedb.pl?show=profile
    2. Under the "Account" tab, create a UDP API key; it can be anything you want. It is used for Avdump2 to connect to AniDB.
  3. Save the options.
  4. Select what you want to scan from the main menu; files or folders.
  5. Select the stuff you want to scan (... Button) (you can select multiple files at once).
  6. Click Start.

Autocreqing

Simple diagram of the way autocreqing with avdump works

Avdump is now part of a new autocreqing system. Some more or less important notes:

  • To be able to use this feature you’ll need an AniDB account and you have to define the api password in your profile. All data sent to the server will be logged with ip and uid.
  • Communication between client and server is one-way (except session init/refresh); the client does not receive any confirmation for sent data. This means that there is no guaranty that all the dumps you send will arrive at the server and stored in the database, and there is no way to check this. From version 0.31 it's possible to make avdump wait for confirmation from the server by using the -o switch.
  • It is possible to run more than one instance of avdump at once, but not more than ten will work ok. At the moment only 10 sessions per ip are allowed by the server, meaning the eleventh instance will terminate the first.
  • There is no direct connection between data sent to AniDB and creqs generated. The data received will just be stored for later processing. There is no way to check the current status for a dump. Usually, it should take at least 24 hours from the moment you dump a file till the data actually changes. If any irregularities occur, or when there is too much data pending, it will take more time.
  • The creqs generated will report the user who sent the data first (for a specific file) as the creqer.
  • You may dump files currently not in the db. The data is still stored and will be used later if/after the file is added. It might also be used for machine assisted file adding at some point.
  • Files creqed by the new system will be locked, meaning some fields will not be possible to change. Notify a moderator if you are sure that some of the data locked for a specific file is wrong.
  • Not all dumps are sent to the server; Only mkv, ogm, avi, mp4, mov, rm and mpeg dumps from non corrupted files are sent:
    • The asf parser does not detect fps.
    • Audio files are too few and not considered important atm.
    • Nothing useful can be extracted from archives and subtitles (that I can think of).

Why didn't this file get dumped?

  • It's not avi/mkv/ogm/mp4/mov/mpg/rm.
  • The file in AniDB is registered with wrong size and/or ED2K hash.
  • The file in AniDB was registed with wrong size and/or ED2K hash at some point (including lame files).
  • The package did never reach the server.
  • The decryption or decompression failed at server side (rare).
  • The dump is not valid XML (rare).

The only way for regular users to check whether a file is dumped or not is to use the mylist report Files with no dump [1] or ask epoximator.

Why isn't this file verified?

Even if the file is dumped it doesn't mean it will get autocreqed (and verified). Here are the reasons:

  • The file is corrupt/invalid (example).
  • The dump was marked unfit for file verification by an AniDB Moderator.
  • The file type is not included in autocreqing yet (mov/mpg/rm atm).

Ask epoximator if you wonder why a certain file is not verified even if it is dumped.

What's the current status?

Look here.
