Arttu Ylä-Outinen 591a1ce6db Turn some inter recon functions static. 
Makes the following functions static since they are not used outside
inter.c:
- kvz_inter_recon_frac_luma
- kvz_inter_recon_14bit_frac_luma
- kvz_inter_recon_frac_chroma
- kvz_inter_recon_14bit_frac_chroma

Arttu Ylä-Outinen 31ba8d61c3 Implement fractional chroma recon for SMP blocks. 
Adds parameter block_height to function kvz_inter_recon_frac_chroma.

Arttu Ylä-Outinen 0b6cef7be5 Remove unused function kvz_inter_set_block. 2015-12-15 11:21:42 +02:00
Arttu Ylä-Outinen dc4525c0e3 Implement inter recon for non-square blocks. 
Adds parameter height to functions kvz_inter_recon_lcu and
kvz_inter_recon_lcu_bipred and makes them work on non-square sizes.
Fractional reconstruction functions do not handle non-square blocks yet.

  candidates A1 and B1.

Arttu Ylä-Outinen 1cd149fb97 Check merge/mv candidate types earlier. 
Moves checks for motion vector prediction and merge candidate block
types (inter/intra) from functions kvz_inter_get_mv_cand and
kvz_inter_get_merge_cand to kvz_inter_get_spatial_merge_candidates.

Marko Viitanen eba298e635 Added cu->inter.mv_ref_coded variable 2015-03-10 09:17:25 +02:00
Ari Koivula 2f79bfebf7 Rename parameter encoder_state to state in all functions. 
- It's so widely used that there isn't really need to emphasize that
  it's the encoders state. Also, it isn't really the encoders state,
  but encoding jobs state.
