Flash Media Encoder 2.5 includes new features for optimal media quality and encoding and streaming operations.

Support for H.264 

Encode live media using the H.264 video codec, and stream it using Flash Media Server 3. Media is saved as F4V files. F4V files can be viewed in Adobe® Media Player, Adobe® AIR™ applications, and Adobe® Flash® Player 9.0 Update 3 or later.

Automatic frame dropping 

To ensure optimal performance even under suboptimal network conditions, Flash Media Encoder 2.5 automatically drops frames from the RTMP buffer while streaming to Flash Media Server, as needed.
