preprocessing on the frames

[ahmadi219]

first thanks for this perfect program, we want to do some process on frames before send them to the wall, i noticed that there is a callback method and frame data in ut8 from, but it seems that in project didn't use that at all, how can i get a frame before send it to wall, do some changes like filters, then send it to the wall?
