I just needed to record a video stream. Usually I use mplayer for these kinds of jobs, but this time it failed. However, on the internet I found a way to do it using VLC, which apparently has quite a command line interface.

encfs is a cryptographic file system. The principle is very easy, you “bind-mount” one directory (containing the crypt stuff) to another directory (where it’s unencrypted). Thus, you can share the encrypted stuff and nobody but you can read your data. So this system is excellent applicable for cloud services like Dropbox, which trap you with some space in the cloud “for free”, but want you to share your private data with them. In some <p>‘s we’ll see how to setup encfs for Dropbox, but let’s first take a look at encfs itself.
