Download videos from various Flash-based video hosting sites, without having to use the Flash player. Handy for saving videos for watching offline, and means you don't have to keep upgrading Flash for sites that insist on a newer version of the player.

Supports Linux, Windows and OS X - see Installation for more details and how to install.
Includes support for the following sites/players (and more!):

YouTube, eHow, Brightcove (used by many sites like Channel 4, Daily Telegraph ...), BBC (news, etc), Metacafe, 5min, Google, fliqz, nicovideo, vimeo, Blip, Break, Collegehumor, Muzu, Sevenload, Megavideo, Wat.tv.
Also includes a 'generic' method which works on many other sites.
Because a picture is worth a thousand words:

When it comes to downloading flash streams from the internet, Wireshark can be used to sniff out the values you need.

Let’s take this site for example: http://videolectures.net/

Start a Wireshark capture session before clicking on a video on the site to play it. Let WireShark grab all the information exchanged between your PC and the remote flash server and you can stop the capture once the video begins to play, we are only interested in what goes on during the connection handshake. I will use this video as an example: http://videolectures.net/ff06_chomsky_szmp/ [update Jun-2008: looks like they changed this particular video to Windows media instead of Flash, so try other videos or other sites]

In WireShark you can filter for protocol “rtmpt” and the first few entries would be handshake or “invoke” operations. Examining the “Handshake part 3″ we can easily get the value of the required “app” property. Below we can see it is “video/2006/other/ff06/chomsky_noam”:

A bigass bulleted list of features.

I commonly need to get a big list of all the stuff people think of when they think new and shiny these days. This list is for that.
