      Improve reference ordering in interleaved 3D video · 247f504d
      Fiona Glaser authored
       Provides a decent compression improvement when encoding interleaved 3D content (--frame-packing 5).
       Helps more without B-frames and at lower bitrates.
       Note that x264 will not do this optimization unless --frame-packing 5 is used to tell x264 that the source is interleaved 3D.
      
      Tests consistently show that interleaved frame packing is by far the best way to compress 3D content.
      It gives a ~35-50% compression benefit over separate streams or top/bottom or left/right coding.
      
      Also finally add support for L1 reference reordering (in B-frames).
      Also add support for reordered ref0 in L0 and L1 lists; could be useful in the future for other things.

      Chroma weighted prediction · f92aa4ec
      Fiona Glaser authored
      Like luma weighted prediction, dramatically improves compression in fades.
      Up to 4-8db chroma PSNR gain in extreme cases (short, perfect fade-outs).
      On actual videos, helps up to ~1% overall.
      One example video with a decent number of fades (ef OP): 0.8% bitrate reduction overall, 7% bitrate reduction just counting chroma.
      Fixes a lot of artifacts in fades at lower bitrates.
      
      Original patch by Dylan Yudaken <dyudaken@gmail.com>.

      Improve quantizer handling · 2f2ab0fa
      Fiona Glaser authored
      The default value for i_qpplus1 in x264_picture_t is now X264_QP_AUTO.  This is currently 0, but may change in the future.
      qpfiles no longer use -1 to indicate "auto"; QP is just omitted.  The old method should still work though.
      
      CRF values now make sense in high bit depth mode.
      --qp should be used for lossless mode, not --crf.
      --crf 0 will still work as expected in 8-bit mode, but won't be lossless with higher bit depths.
      Add bit depth to statsfiles.
      
      These changes are required to make the QP interface sensible in combination with high bit depth.

      Disable weightp offset=-1 dupes with high bit depth · 506683ae
      Fiona Glaser authored
      They're a hack to compensate for crappy rounding, and thus not worth doing at high bit depth, which fixes most of the rounding issues.

      Move DTS compression from libx264 to x264cli · e4b44c2e
      Yusuke Nakamura authored
      DTS compression is an ugly stupid hack and starting to encroach on unrelated areas like VBV.
      Some people want it in the mp4 muxer for devices and/or splitters that don't support Edit Boxes.
      We just say "throw these broken devices out the window".
      DTS compression will remain as a muxer option, --dts-compress, at the user's own risk.
      This option is disabled by default.

      Add support for level 1b · ceba5dd5
      Takashi Hirata authored
      This level is a stupid hack in the H.264 spec, so it's a stupid hack in x264 too.
      Since level is an integer, calling applications need to set level_idc=9 to use it.
      String-based option handling will accept "1b" just fine though, so CLI users don't have to worry.
