Question

I want to know if it is possible to get the decoded frames from FLVPlayback, or if it is known another alternative to access the decoded frames from a flash player.
What I want to do is to manipulate the decoded frames before they get rendered on screen.

The video source could be an RTMP stream or a FLV (F4V) file.

Any hint is welcome 🙂

Answer 1

In what way do you wish to modify them?

If you need to do any per-pixel operation, and are not using Flash Player 10 (in which case you should look up Pixel Bender), you can use the BitmapData.draw() function to draw your frame into a BitmapData. You can then manipulate the pixels as you wish.

var bmp : BitmapData = new BitmapData(myVideo.width, myVideo.height, false);

// Each frame, do this:
bmp.draw(myVideo);

If you just simply want to apply some sort of generic filter, like blur, you can look up the flash.filters.* classes instead, e.g. BlurFilter, DropShadowFilter or ColorMatrixFilter.
