Multiple audio langauge

[logonsuresh]

Hi People,

How to develop multiple audio language in as3?

I have video that edited in FCP with english audio but that video contains 3 more language.

How can i change language audio in flash.

Am using netstream concept. My video is in m4v format.

Please help.

adjust your play() method's argument to use the video with the desired language.

You haven't indicated your target for playing the videos. Is it a website, app, desktop application, etc?

If it is getting the video content from a streaming server, you can choose alternate audio tracks from the same video using Flash Media Server 4 or later. Open Source Media Framework (OSMF Player) has support for that built-in as long as you have the server. Here's an old article with the relevant info:

And OSMF's guide:

Open Source Media Framework Developer’s Guide * Supporting alternate audio tracks in HTTP Streaming ...

If it is a local media setup (kiosk, off a CD/DVD/BR, etc) then for ease, disk space is pretty cheap, so do as Kglad said and separate them into different video files. You should just embed the alternate audio streams in different video files rather than trying to using a separate audio and video file in sync. If you're doing it for a lot of languages, it's not ideal, but there's not much room here.

You should plan on video duplication with a single audio stream for each language, or, to chop the video into smaller segments timed to each VO segment while streaming each of them concurrently. Making a whole audio track for a long video will almost certainly eventually get frustratingly out of sync if people are talking on-screen. However you can eep by if lip sync is not necessary in a narrated context.

To my knowledge, Flash streaming servers are necessary for stream selection. It is a server-side bit of metadata that makes the client audio selection possible. I could be wrong on that detection in the latest versions however.
