Sebastian Dröge 089d9d9dba videomixer: Don't do floating point math in the inner processing loop for I420 blending 2009-12-11 12:36:42 +01:00
Sebastian Dröge 4ccd9c92ae videomixer: Remove the calculate_frame_size() function and use libgstvideo instead 2009-07-10 17:23:03 +02:00
Edward Hervey b02949faeb videomixer: I420 mode: Add fast path for 0.0 and 1.0 alpha 
If the source alpha is 0.0, we take nothing.
If the source alpha is 1.0, we overwrite everything.

Edward Hervey 3c88249d48 videomixer: I420 blending : Fix main algorithm. 
When blending a source layer with an alpha of 'a' on top of another
destination layer we take the sum of:
* 'a' percent of the source layer
* (100 - 'a') percent of the destination layer (the remainder)

Sebastian Dröge 83fc39ccff videomixer: Some cleanup and fix the calculation of the frame size in bytes 2009-05-28 13:54:14 +02:00
Sebastian Dröge 699b696db8 videomixer: Fix I420 blending to actually do something 
For this we a) implement the checkers filling and b)
actually blend the src/dest by using the src alpha value
from the pad.
