Extracting mkv attachments without attachment ID

[nuaris]

I have a few .mkv files that I want to extract the attachments from, mostly fonts.

Is it possible to extract all attachments in a .mkv file without the attachment ID?

Try Avinaptic - Demux > Demux all attachments

or this (http://www.videohelp.com/tools/MKVExtractGUI)

Or as explained here (http://forum.doom9.org/showpost.php?p=1127627&postcount=4) using MatroskaProp.

Thanks, I tried Matroskaprop and Avinaptic. Is there an option or command line to extract the attachments in batch for multiple files?
