...component is interpreted as being at quarter-pixel resolution, i.e. -7.75 . . . 7.75 pixels. The precise details of how these vectors are used to compute predictors for each block are described in Section 7.9.1. " But nowhere, decoded values are divided by two. Algorithm in 7.5.1 gives MVX and MVY in -31..31. Algorithm in section 7.5.2 keep these values. In section 7.9.1.3, the use of MVX2 and MVY2 seem to be the solution but in algorithm 7.9.4, these two variables are initialized with the same value : B. Assign MVX the value |MVECTS[bi ]x | ? sign(MVECTS[bi ]x ). C. Assign MVY th...

Dear everyone, The in-progress release notes for 3.7 [1,2] make it look like we didn't do very much over the past six months. Obviously that's not the case at all, so let's get them in shape! If you've been thinking "I should probably add this to the release notes at some point", now is the time :-) I have a list below of changes that might be worth mentioning. I

Hi all, After the previous RFC[1], there were multiple discussions on the ML and in person at the DevMtg. I will summarize the options discussed and propose a path forward. =========================== Options =========================== A. Extend VectorType to be multidimensional B. Flatten matrices into the current VectorType. Matrix shape and layout information is passed to matrix
