[Soc-2013-dev] Weekly Report #8 VSE

[Alexandr Kuznetsov]

==Week 8==
* Implemented resampling algorithms on GPU
** Nearest neighbors
** Bilinear
** Bicubic
* Added very simplistic manipulation from view
** Doesn't take into account relative size/position yet
* Implemented Canvas
** The transformation propagates to the first input
** Still it has weird problems if the output is used more than once
* Looked into cpu vectorization. The cpu probably 4 times slower that it 
is supposed to be. There is no universal solution for compilers that I 
found so far.


==Next Week Todo==
* Finish canvas and transformation
* Enable (ram) caching and buckets that span several frames
* Implement 3 scopes and support for multiple video outputs (different 
stages and resolutions)



== Questions ==
* Current sampling algorithms skip pixels if the new image size is less 
than a half. This can create a serious artifacts.
