The FLV file format
Starting with SWF files published for Flash Player 6, Flash Player can exchange audio, video,and data over RTMP connections with the Adobe Flash Media Server?. One way to feed data to Flash Media Server (and thus on to Flash Player clients) is from files in the FLV file format.
Starting with SWF files published for Flash Player 7, Flash Player can also play FLV files directly with MIME type video/x-flv.
An FLV file encodes synchronized audio and video streams. The audio and video data within FLV files are encoded in the same way as audio and video within SWF files.
This document describes FLV version 1. For more information on the FLV format, see Chapter 1, “The FLV File Format,” on page 3.
The F4V file format
Starting with SWF files published for Flash Player 9 Update 3 (9,0,115,0), Flash Player can play F4V files. The F4V format is based on the format specified by ISO/IEC 14496-12: ISO base media file format. For more information on the F4V format, see Chapter 2, “The F4V
File Format,” on page 15.
A large part of the F4V format involves metadata. For more information on F4V metadata,see Chapter 3, “F4V Metadata,” on page 33.
