  vp9: Add bsf to fix reordering in raw streams

  possibly out of order and inserts additional show-existing-frame
  packets to correct the ordering.

• arm/aarch64 : vp9 : Fix vertical alignment

  8 janvier 2017, par Martin Storsjö

  arm/aarch64: vp9: Fix vertical alignment
  
  Align the second/third operands as they usually are.
  
  Due to the wildly varying sizes of the written out operands
  in aarch64 assembly, the column alignment is usually not as clear
  as in arm assembly.
