.flv and .swf format useage

Answer 1

FLV files (Flash Video Files), a binary file format, are composed of a video bit stream and an audio bit stream and deliver web video over the Internet with Macromedia Flash Player. FLV files are considered to be streaming video files. If you put FLV file in website, you don't have to download the entire file before playing. FLV content may also be embedded within SWF files. The audio and video data within FLV files are encoded in the same way as they are within SWF files. Unlike SWF format, FLV do not have maximum of 16000 frames limitation and ideally for large video file size. Notable users of the FLV format files are YouTube, Yahoo video, Google Video, Reuters.com, My Space, Facebook video etc.

SWF (Shockwave Flash)- The file format SWF is a vector graphics file format, not streaming media. SWF file can be played directly in web browser, such as Internet Explorer. However, FLV file can not be playback directly, because it requires a separate SWF file which reads the video content from FLV. The SWF file that plays FLV file is called online flash player. Intended to be small enough for publication on the web, SWF files can contain animations or applets of varying degrees of interactivity and function.
