How to record Audio and Video at the same time into flv in Adobe air 2.0?

How to record Audio and Video at the same time into flv in Adobe air 2.0 ? So that Video and 开发者_运维问答Audio will be sinchronised?

Open Source libs and Blog aricales are wellcomed!)

All I can help with are a few links, but I haven't tried this to know how feasible it actually is:

1. Audio - Recording record microphone to wav devnet article or devnet cookbook article.
2. Audio - Compression - MP3 Compression with Lame and AIR 2.0 or MP3 encoder in Flash with Alchemy
3. Video - SimpleFlvWriter.as is a bit outdated and only writes images, not audio, but might be handy to get started. Also have a look at the FLV Specs.

At this point it looks like trouble waiting to happen: Where do you store the images/sound until you write encode them ? in RAM ? If you want to cache uncompressed files, will there be audio delays ?

It might be worth trying something different, like C++. Or at least, write some command line tools for recording/encoding for performance reasons and use AIR/native process just for the looks/interaction ?
