Avdump2
Welcome to the remarkably sparse avdump2 wiki page, lovingly hand created over many minutes.
We gleefully embrace build 4334, the 'it works on windows!' edition, yet another public release of avd2. It represents a complete rewrite of the original avd1 code, runs against a new build of MediaInfoLibrary, contains a number of custom solutions for a number of formats, represents a significant investment of time and energy by Arokh, and is just generally nifty.
This release contains a minor collection of fixes from previous releases, and, barring discovery of world-ending bugs in the interim, will be the first version to be formally announced on the web site proper. As before, there is no need to reprocess existing files with this build, but do keep an eye out for misbehaviour.
What is it
Avdump2 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, like its predecessor, is mainly based on mediainfo, but significantly enhanced and changed to fit AniDB's needs by Arokh.
Supported formats
Most major file formats are supported to some degree. While hashes are created for all file types, stream details remain shakey for others (notably 'swf'). Because of that for some filetypes (underlined) only the hashes get auto-creqed.
- Video files: asf/wmv, avi, flv, m2ts, mk3d, mkv, mov, mp4, mpg/mpeg, ogm, ogv, qt, rm/rmvb, swf, ts, webm
- Subtitle files: ass, idx, js, lrc, mks, pjs, rt, smi, srt, ssa, sub, tmp, tts, txt, xss
- Audio files: aac, ac3, dts, dtshd, flac, m4a, mka, mp3, ogg, ra, thd, wav, wma
- Archive files: 7z, ace, rar, zip
- Linker files: mkv, smil

Changes From Avdump Classic
- AVD2 now runs on the managed .net platform. This will not affect most, as .net comes pre-installed with current versions of windows. XP or older may have to install the platform manually. While it has been tested on mono, such testing has not been exhaustive. We would be very interested in hearing how it behaves in such an environment.
- While most command line parameters remain the same, there are some exceptions.
- The "-o" parameter is no longer available in avd2.
- The "-n" parameter is no longer available in avd2.
- The meaning of the numeric parameters has changed.
- In the event of an internal error, AVD2 will submit an error report back to AniDB. The error report contains no user-details (see sample), but is attached to the user name supplied with the -ac parameter. While error reports are only submitted if -ac is specified, they can be disabled by the addition of the -noerr parameter. That said, for the purposes of initial testing, we respectfully request that error reports not be disabled, so bugs can be found and fixed.

Avdump2 on Linux
Thanks to Mono, Avdump2 runs natively on Linux as well. However, as most development effort goes into the Windows version and due to the heterogenity of Linux distributions, running Avdump2 on Linux isn’t as straightforward as running it on Windows. All Linux-related usage notes can be found on the Avdump2 on Linux page.
Auto-creqing
Avdump2 is the AniDB 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.
- 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.
Why didn't this file get dumped?
- 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.
Known issues
- In some cases MediaInfoLib (MIL) used by Avdump2 might report an audio stream to have 0 or 3 channels.
- Anamorphic .asf/.wmv and .mpg/.mpeg files might not get detected correctly and will report the PAR instead of the DAR.
