Nice work man you should develop this in to a full featured library

Hi Jérémie,

I was wandering if you have found a way to create an MP3 from a ByteArray? I’ve been trying for more a day now but with little success.

Thanks!

Atanas.

I know it’s possible with a FLV, because I did it already.
The main thing is you have to parse the FLV to single FLV frames and put them in a SWF. Both specifications are open and downloadable at the adobe site.

very cool!
i know you can get an flv in a byteArray when you load using fileReference.data so you recon its possible to do the same with an flv?

Haha! I found a bug My MP3 Encoder creates MP3’s that can’t be loaded this way. I’ll have to take a look at it.

Do you know if there is a way to do the opposite : to create a mp3 file from a ByteArray, build with the SoundMixer class ? My goal is to generate a FLV file, from several external ressources (videos, sounds, graphics…).

Well the audioframe is my own class. It loads a mp3 into a bytearray. Then I analyze the mp3 and pick out all frames. When you create a SWF you can add mp3 frames to a sound object like it’s an embedded sound.
When I tidy up some of the code I will post some more.

Very cool. With this technique can you load the swf and access the data as a Sound object? How would you play the mp3? Is there a way to generate a Sound instance and load the data into it outside of a URLRequest?

I was using the precompiled SWF / Sound object technique you mentioned above until I decided to use fvorbis instead for my audio needs.

But I’m interested in how you accomplish accessing the mp3 (AudioFrame in particular) and writing it out to generate a proper swf for playback.

I guess I’ll have to look link the SWF specs sometime.

Thanks for the post. I hope to see more on this!
