Flash Player

 * Main article: Adobe Flash Player

The Adobe Flash Player is a multimedia and application player created and distributed by Adobe. It plays SWF files which can be created by the

Adobe Flash authoring tool, Adobe Flex or a number of other Adobe and third party tools. It has support for a programing language called

ActionScript, which can be used to display Flash Video from an SWF file. Because the Flash Player runs as a browser plug-in, it is

possible to embed Flash Video in web pages and view the video within a web browser.

Video format
Commonly FLV files contain video bit streams which are a variant of the H.263 video standard, under the name of Sorenson Spark.

Flash Player 8 and newer revisions support the playback of On2 TrueMotion VP6 video bit streams. On2 VP6 can provide a higher visual quality than

Sorenson Spark, especially when using lower bit rates. On the other hand it is computationally more complex and therefore will not run as well on certain

older system configurations.

An optional alpha channel which represents per pixel transparency is supported by including a second simultaneous video stream which encodes the alpha

channel only, dropping any chromatic information. The implementation makes the assumption that the YUV data of the main On2 VP6 video

stream is always converted to RGB by the client before compositing occurs as the resulting RGB values are

alpha premultiplied and clamped accordingly. This option is only available for On2 VP6 encoded video streams.

The FLV file format supports two versions of a so called 'screenshare' codec which is an encoding format designed for screencasts. Both these formats are

bitmap tile based, can be lossy by reducing color depths and are compressed using zlib. The second version is only playable in Flash Player 8 and

newer.

Support for encoding FLV files is provided by an encoding tool included with Adobe's Macromedia Flash Professional 8 product, On2's Flix encoding tools,

Sorenson Squeeze, ffmpeg and other third party tools.
