Audio pops and glitches occur during transitions with dynamic streaming using Adobe Flash Media Server (FMS).
When audio is encoded at different bit rates, pops and glitches are more likely to occur when transitioning with dynamic streaming.
For video on demand (VOD), you can use any encoder. Use your favorite video encoding tool, or the new Flash Media Encoding Server, and encode VP6 (FLV) or H.264 (F4V) video. Implementing dynamic streaming with Live content requires an encoder that can synchronize streams. Currently, Flash Media Live Encoder 3 is the only encoder that can synchronize streams.
