If you modified ''any'' of the required files Avdump2 came with, you will either get a version error or several timeouts and no meaningful error message. So no, you can’t edit the config file either. | If you modified ''any'' of the required files Avdump2 came with, you will either get a version error or several timeouts and no meaningful error message.

This error appears if you try to process a file with special characters in its name and your locale settings don’t match the file system encoding. Nowadays almost all file names are encoded with UTF-8 on Linux, so your locale should use that as well. If you work remotely on a server that sets LANG to “C” by default, it won’t work. Try setting LC_ALL=en_US.UTF-8, because that locale is installed almost everywhere by default. LC_ALL takes precedence over LANG. | This error appears if you try to process a file with special characters in its name and your locale settings don’t match the file system encoding.

If you have a file with bogus characters in its name, even changing the locale won’t help. You have to rename the file to something sensible. | If you have a file with bogus characters in its name, even changing the locale won’t help. You have to rename the file to something sensible. | ||

To make using Avdump2 more comfortable, you can use or modify this wrapper script to handle the workarounds. Save it as <tt>/usr/local/bin/avdump2cl</tt>, for example.
