Avdump2 on Linux

Avdump2 was developed on Windows, for Windows. Thanks to Mono it’s possible to run Avdump2 on Linux and all efforts are made to support all basic features on Linux as well, but handling every peculiarity of every Mono version on every Linux installation is beyond the scope of Avdump2 at this time. Therefore, some things just don’t work on Linux, or at least not right away, without some workarounds.

This page is a collection of various workarounds and suggestions that should help you get started with Avdump2 on Linux.

The Basics

Can't get Avdump2 to work at all? Here are some basic suggestions to set up Adump2.

Mono

Avdump2 has successfully been tested with Mono 2.4 on Ubuntu and with Mono 2.8 on Gentoo.

Avdump2CL.exe looks like a Windows .exe, how do I start it?

Try making the file executable. If that doesn’t work, call it using the mono Interpreter: mono Avdump2CL.exe

Avdump2 keeps looking for /some/directory/mono

If you extracted Avdump2 into /some/directory and it won’t work because it can’t find /some/directory/mono, you might have a buggy Mono version. This has been observed with Mono 2.10 on Gentoo and downgrading to Mono 2.8 solved the issue.

libMediaInfo

A special version of libMediaInfo is required for Avdump2 to work and if it can’t find the one it comes with, you will usually get Media Info Library not found. Don’t try to provide your own because the files are hashed and unknown versions will produce odd errors when you try to dump a file.

There are many possible causes if the library can’t be found.

Library search path missing

Most likely Mono can’t find the binary library even if it’s in the same directory as Avdump2CL.exe. Then you’ll have to set the environment variable LD_LIBRARY_PATH to point to the diretory into which you extracted Avdump2. Write yourself a wrapper script to do that or have a look at the example wrapper scripts below.

Incompatible GLIBC

If your Linux installation is very old or you’re using a distribution that ships with an outdated GLIBC (CentOS is a prime offender here), Mono can’t link against libMediaInfo and Avdump2 will still complain about missing the library. To check if that’s the case, use ldd libMediaInfo*.so. If you get a message like version 'GLIBCXX_3.4.9' not found, you’re out of luck. You can either try to update GLIBC, which usually involves pain, or upgrade or change your distribution to one with a newer GLIBC.

Hashing works but I can’t dump anything

If you modified any of the required files Avdump2 came with, you will usually get the misleading error Either the client is outdated or your username/password combination is wrong. So no, you can’t edit the config file either.
