We're working on a solution to attach images to each flv's frames, we're exploring the possibilities to encode them in the alpha channel. Reading the alpha channel works well so we get the informations we need. The problem is that those informations don't have the usual meaning of an alpha channel and we would like to display the video without taking them into account.
We tried applying a color matrix filter to the flash.media.Video, but it seems to be applied to the rendered video..thus with a "baked" alpha.
I've search the forum for solutions and only find questions about alpha channel working, well I need my alpha channel not to work.
