augmented reality - grabbing frames

[stanley310]

i have the augmented reality sample working in my own app. i am overlaying my andengine content over the camera preview and i can get the camara to take pictures. problem is i want to overlay my AR over the camera shot and save this file, and the camara callback only gives me the raw jpg data to save.

my thought is that i need to grab the entire andengine scene (camera preview background and all layers) and save to file, instead of using the camera take picture function. anyone have any ideas on how to grab the "screen buffer" for this?

anyone have any thoughts one this?

thanks
