Question

In the Flash ver.11.3 release one of the changes is:

Low latency audio support for streaming audio through NetStream — This
feature aims to reduce latency for high quality streaming audio
playback. It addresses a very special use case of cloud gaming, where
the game is rendered at a server and audio and video are streamed to
the client.

Can someone explain me what does that mean? Does it mean that any audio streamed via NetStream will be automatically improved in latency respect in this version of Flash player? Or some special settings must be applied on the NetStream so that the audio will be considered as “low latency”? May be this change is applied only to some certain audio formats streamed via NetStream?

Generally the question is: do I need to do any changes on my server, which broadcast live audio via NetStream, or in the audio player which is built with Flex, which listens to this audio, to take advantage of this new Flash release?

Thank you.

Answer 1

I found some details in the release notes, which mention a new boolean property, useJitterBuffer, that has been added to NetStream.

This article says you can set bufferTime = 0 and useJitterBuffer = true to activate the new feature.

Finally, this forum post says you also need to use swf-version=16 in the compiler options.

So to answer your question: you need to make the changes above on the client. The only server side change seems to be to require Flash 11.3.
