Question

I need to compress video image data (lets say a display object) in AS3 to a Byte Array with high compression at runtime. Framerate only needs to be around 5 but 1024×768 video needs to go to < 40 Kilobyte per Second without the quality beeing tooo bad. I wrote a custom encoder and got it to around 80-100 Kilobyte per Second for 1024*768 which still is too much and i dont see a lot of improvements to be mad to my encoder.

Using JPG or PNG Encoder gives way higher KB/s. Is there any open source way to to decode and encode video in as3 at runtime ? E.g. a H.264 as3 encoder and decoder ? Or other codecs ?

Or maybe a C# source code of h.264 encoder and decoder ? I think i could port it to as3…

EDIT: Doesnt need to be h.264, just something with good quality when running at 5 Frames/Sec and 40 Kilobyte…

Flash Player 11 (beta) has H.264 encoding:

H.264/AVC SW Encoding — Encode higher quality video locally using H.264 video.

Edit: Flash Player 11 is no longer beta
