      dvenc: fix 2x4x8 (interlaced) weight table · cb335b3a
      Christophe Gisquet authored
      Since the decoder has been fixed to output something similar to
      other implementations, the encoder weight table needed this fix.
      
      Reference PSNR values on a progressive sequence (from tiny_psnr)
      from a chained encoding and decoding:
      Full progressive: stddev:    0.74 PSNR: 50.69 MAXDIFF:   19
      Before:           stddev:    1.43 PSNR: 44.97 MAXDIFF:   17
      This patch:       stddev:    0.76 PSNR: 50.44 MAXDIFF:   14

      lowres2 support. · 70d54392
      Michael Niedermayer authored
      The new lowres support is limited to decoders where lowres decoding
      is possible in high quality.
      I was not able to measure any speed difference, but if one is found
      the 2-3 lines that might affect speed can be made compile time conditional
