History

Version 1.0 was released on February 23, 2007.

Version 2.0 was released on October 26, 2007, adding the following functionality:
  • Encoding support for MP3 format
  • Command-line execution
  • Automatically start at operating system launch
  • Automated maintenance restart
  • Remote access
  • Ability to set reconnect interval
  • Timecode support


Version 2.5 was released on April 14, 2008 with the following added features:
  • Encoding support for H.264/HE-AAC format
  • Improvements to Quality of Service
  • Auto-adjust functionality, which enabled dynamic downgrading of the outgoing stream quality if network connectivity was sub-optimal.


Version 3.0 was released on January 12, 2009 with the following added features:
  • An updated user interface and additional presets
  • Multi-bitrate encoding (up to three different bitrates)
  • File management improvements (save multiple files based on file size/duration, parameters in filenames)
  • DVR functionality
  • System timecode support (SMPTE, LTC, VITC or BITC timecodes could be used if supported by capture device; if not, the system timecode could be used)
  • Multi-core processing capability for VP6 encoding
  • Support for additional compatible devices

Usage

  • Stream live video from capture cards, webcams, Firewire, or USB devices to Flash Media Server (FMS) or a Flash Video Streaming Service (FVSS). (Device or driver must support Microsoft DirectShow filters to be recognized by FMLE.)
  • Archive FLV or F4V file locally.

Function

FMLE is a desktop application that connects to a Flash Media Server (FMS) or a Flash Video Streaming Service (FVSS) via the Real Time Messaging Protocol

FMLE integrates directly with Flash Media Server functionality, including recording a readable-while-open live stream file that enables DVR-like seeking during playback of live events. It is also possible to encode multiple files at once — at different bitrates — to support Dynamic Streaming (adaptive bitrate streaming).

In addition to encoding live events with finite start and end times, features such as command-line control, auto reconnect, and remote access enable efficient 24/7 encoding.
