2015-06-03Make vp9 subpixel match vp8Johann
The only difference between the two was that the vp9 function allowed for every step in the bilinear filter (16 steps) while vp8 only allowed for half of those. Since all the call sites in vp9 (<< 1) the input, it only ever used the same steps as vp8. This will allow moving the subpel variance to vpx_dsp with the rest of the variance functions. Change-Id: I6fa2509350a2dc610c46b3e15bde98a15a084b75
2015-05-26Move variance functions to vpx_dspJohann
subpel functions will be moved in another patch. Change-Id: Idb2e049bad0b9b32ac42cc7731cd6903de2826ce
2015-05-07replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNEDJames Zern
this macro was used inconsistently and only differs in behavior from DECLARE_ALIGNED when an alignment attribute is unavailable. this macro is used with calls to assembly, while generic c-code doesn't rely on it, so in a c-only build without an alignment attribute the code will function as expected. Change-Id: Ie9d06d4028c0de17c63b3a27e6c1b0491cc4ea79
2015-05-06Move shared SAD code to vpx_dspJohann
Create a new component, vpx_dsp, for code that can be shared between codecs. Move the SAD code into the component. This reduces the size of vpxenc/dec by 36k on x86_64 builds. Change-Id: I73f837ddaecac6b350bf757af0cfe19c4ab9327a
