Note!



Avdump (version one) has been wholly superseded by Avdump3. While the version of Avdump on this page will continue to work for auto-creqs for the foreseeable future, users are encouraged to migrate to the new version as the opportunity presents itself.










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 bit rates, the length, identifies the number of used audio channels 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 standardize the input for files and be a part of the upcoming AOM 0.6. It does however already support auto-creqing by itself. See Avdump/Auto-creqing.

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.
  • Currently Avdump only supports lower-case letters in user name, if your AniDB user name has capital letters, lower case them only for Avdump usage (as in, it's not needed to change your AniDB user name). If your AniDB user name contains symbols such as an underscore _, then you will actually need to remove that from your AniDB user name for Avdump usage.
  • 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.
  • Only full parsing of avi, mkv and ogm container formats.
  • Avdump is only for Windows at the moment. It works via Wine though.

Usage

Avdump is a simple command line client:

avdump [-<options> ...] <media file/folder> [<media file/folder> ...]

Options

Switch Info Example
ext:<comma separated list> Only process files with the specified extensions. ext:mkv,avi
log:<file path/name> Mirror the output to the specified file. log:avdump.log
exp:<file path/name> Export ed2k-links to the specified file. Very useful when mass adding files. exp:ed2k-links.txt
ac:<username>:<udp_api_key> Enable automatic creqing. You should always use this option when dumping anime files! -ac:tard:monkey
port:<port number> Use the specified UDP port for communication with the AniDB server (api.anidb.net). Only needed when behind "strict" firewalls. port:1337
done:<file path/name> Save processed-file-paths to the specified file and exlude existing entries. done:done.txt
tout:<timeout_in_seconds>:<number_of_retries> Set timeout options. tout:15:6
bsize:<KB_per_block>:<number_of_blocks> Set size per block (2048 is default) and number of blocks in the circular buffer for hashing. If number of blocks is less than 2 then a plain single-threaded hasher is used. Might be useful if you got trouble with the default hasher. bsize:512:16


Note The udp_api_key is not your user password!!! see Auto-creqing .

Windows Shortcut

  1. Extract Avdump to a folder of choice.
    Example: "C:\Program Files\avdump\"

    You can also set other options like s, x or t if you wish to do so.
    A commandline option to export ED2K links to a file is by adding -exp: C:\Path\filename.txt, etc.

Processing DVD's

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

Something like -bsize:256:1 (default is 2048)

Auto-creqing

 
Simple diagram of the way auto-creqing with Avdump works

Avdump is now part of a new auto-creqing 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 UDP API Key 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 database. The data is still stored and will be used later if/after the file has been registered.
  • 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 package never reached the server.
  • The decryption or decompression failed at server side (rare).
  • The dump is not valid XML (rare).

Why isn't this file verified?

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

  • The file is corrupt/invalid (example).
  • The provided data is considered "incoherent". (Indicates a bug in Avdump.)
  • The dump was marked unfit for file verification by an AniDB Moderator.
  • The file type is not included in auto-creqing yet (mov/mpg/rm ATM).

What's the current status?
