Flash Player 10 Out With New Audio And Video Features

In a prerelease of Adobe Flash Player 10 code name "Astro", the noticable features are audio and video features which will be available with proposed future release of Adobe Flash Media Server.

Dynamic Streaming

As streaming is dependent on newtwork condition, Dynamic Streaming will provide best quality video and will be auto adjustable based on bandwidth availability. Video streams over RTMP from proposed future releases of Flash Media Server can dynamically change bitrate as network conditions change.

RTMFP (Real Time Media Flow Protocol)

According to Adobe- RTMFP provides a UDP-based secure network transport alternative to RTMP-over-TCP. To take advantage of the feature you will need to establish a net connection via future releases of Flash Media Server or other Adobe server products. UDP (User Datagram Protocol) is an efficient and standardized Internet protocol for delivering media assets because of its support for lossy delivery, improving performance of real time communication. RTMFP is always encrypted which helps protect media delivery. This technology is a result of Adobe's acquisition of Amicima, Inc. in 2006. To know more about this new protocol, read RTMFP FAQ.
