[XviD-devel] improving data flow during interpolation

[peter ross]

hey skal.

michael has already said this, but iam gonna say it again: *welcome to the 
dev mailing list*

the current bframe decoding code is wasteful; there's individual functions 
for the different bframe modes. these can be replaced by simply modifying 
the existing mb_inter function to accept 2 vectors: eg.

mb_inter(...VECTOR * mv_f, VECTOR * mv_b...)
{

   interpolate8x8_XXX(...mv_f...)
   interpolate8x8_XXX(...mv_f...)
   interpolate8x8_XXX(...mv_f...)
   interpolate8x8_XXX(...mv_f...)

   if (mv_b != NULL)
   {
      interpolate8x8_XXX_add(...mvf_b...)
      interpolate8x8_XXX_add(...mvf_b...)
      interpolate8x8_XXX_add(...mvf_b...)
      interpolate8x8_XXX_add(...mvf_b...)
   }

   // bitstream decode, dequant, compensate
}

this is how i originally implemented bframe decoding. however my 
implenentation never made it to cvs...
