Flash Video

From Wikipedia:

Flash Video is the name of a file format used to deliver video over the Internet using Adobe Flash Player (initially produced by Macromedia) versions 6–10. Until version 9 update 2 of the Flash Player, Flash Video referred to a proprietary file format, having the extension FLV. The most recent public release of Flash Player supports H.264 video and HE-AAC audio. Flash Video content may also be embedded within SWF files.

Flash Video is viewable on most operating systems, via the widely available Adobe Flash Player and web browser plugin, or one of several third-party programs such as MPlayer, VLC media player, Quicktime, or any player which uses DirectShow filters (such as Media Player Classic, Windows Media Player, and Windows Media Center) when the ffdshow filter is installed.

Since Flash Player 9 Update 3 Flash Video also supports the MPEG-4 international standard.

A Flash Player 9 update including a new MP4 H.264 component was released on December 3, 2007

The primary downside of Flash's FLV player is that it is very inefficient compared to a directly embedded video file, dropping frames when running on slow clients that run directly embedded video perfectly.

An FLV player is a type of media player that is used for playing flash video from PC as well as from Internet websites. An FLV player can be used standalone ..

Many videos on this site are also offered as MP4 attachments; if you don't have Adobe's Flash Player Plugin or a standalone Flash Player installed, you might be able to play the attached MP4. Also, this will often give better performance (no dropped frames).

The (X,Y,Z) channels of five 3D accelerometers vary the amplitudes of notes of fixed (C,E,G) chords at different octaves. When the amplitude varies by small amounts about a larger mean value (such as when waving the arms about a common raised level) the mode can be said to represent Amplitude Modulation (AM).

This is a subtle mode, and care must be taken to sufficiently distinguish the notes of each chord triad. Amplitude variation can also be well combined with other modes such as variation of the frequency of oscillators.
