What is FLV?
FLV, or Flash Live Video file, is a preferred file format that is designed for web playback, offering high rates of compression to deliver video over the Internet using Adobe Flash Player.
FLV content cannot be played back directly but must be embedded in (or linked from) an SWF file. You create (or download) a "container" SWF file from which to play the FLV file. The most common approach is to use an SWF file that functions as a media player with screen and playback controls. Notable users of the FLV format include YouTube, Google Video, Reuters.com, Yahoo! Video and MySpace.
What is AAC?
Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme fordigital audio. AAC is promoted as the successor to the MP3 format by MP3s creator, Fraunhofer IIS.
Depending on the encoder used, AAC generally achieves better sound quality than MP3 at the same bitrate, particularly below 192 kbit.
AACs most famous usage is as the default audio format of Apple's iPhone, iPod iTunes, and the format used for all iTunes Store audio (with extensions for proprietary Digital Rights Management (DRM) where used).
AAC is also the standard audio format for Sonys PlayStation 3 and the video standard. HE-AAC is part of digital radio standards like DAB+ and Digital Radio Mondiale.
