Avdump

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.

Known issues

Track sizes might be slightly wrong for OpenDML files. (Data in RIFF:AVI:movi is ignored atm.)
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)

MP3 VBR check does only detect bitrate switching. (variable frame size)
Missing bits in obscure containers. (ie. not mkv/ogm/avi/mp4)

Duration and track size in some mpg files.

Usage

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

avdump [-pstx] <media file/folder> [log file]
Options: (all in one)

p - pause when finished
s - short output
t - time used (per file)
x - xml output

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

Right-click any media-file, goto "Send To", choose avdump (or whatever you called the shortcut)
Be happy :D
