      Fixed mb_skip_coeff bug · 0ccefd2c
      Scott LaVarnway authored
      When mb_skip_coeff is set, the idct is not necessary.  Prior
      to this patch, the code would call idcts based on leftover
      eob information.  This patch will now skip the idct for
      SPLIT_MV and clear out the eobs for B_PRED, forcing the idct
      to be skipped.

      vpx_integer.h: fix incorrect type emulation · a4e410a3
      John Koleszar authored
      The previous definition of uintptr_t was incorrect on x64 with MSVC.
      Also, the ARMV6 version of int_fast16_t was defined as unsigned for
      some reason. Since the fast types are currently unused, just remove
      them.

      Multiple-resolution encoder · aa7335e6
      Yunqing Wang authored
      The example encoder down-samples the input video frames a number of
      times with a down-sampling factor, and then encodes and outputs
      bitstreams with different resolutions.
      
      Support arbitrary down-sampling factor, and down-sampling factor
      can be different for each encoding level.
      
      For example, the encoder can be tested as follows.
      1. Configure with multi-resolution encoding enabled:
      ../libvpx/configure --target=x86-linux-gcc --disable-codecs
      --enable-vp8 --enable-runtime_cpu_detect --enable-debug
      --disable-install-docs --enable-error-concealment
      --enable-multi-res-encoding
      2. Run make
      3. Encode:
      If input video is 1280x720, run:
      ./vp8_multi_resolution_encoder 1280 720 input.yuv 1.ivf 2.ivf 3.ivf 1
      (output: 1.ivf(1280x720); 2.ivf(640x360); 3.ivf(320x180).
      The last parameter is set to 1/0 to show/not show PSNR.)
      4. Decode:
      ./simple_decoder 1.ivf 1.yuv
      ./simple_decoder 2.ivf 2.yuv
      ./simple_decoder 3.ivf 3.yuv
      5. View video:
      mplayer 1.yuv -demuxer rawvideo -rawvideo w=1280:h=720 -loop 0 -fps 30
      mplayer 2.yuv -demuxer rawvideo -rawvideo w=640:h=360 -loop 0 -fps 30
      mplayer 3.yuv -demuxer rawvideo -rawvideo w=320:h=180 -loop 0 -fps 30
      
      The encoding parameters can be modified in vp8_multi_resolution_encoder.c,
      for example, target bitrate, frame rate...
      
      Modified API. John helped a lot with that. Thanks!

      Modified the inverse walsh to output directly · 4a91541c
      Scott LaVarnway authored
      to the dqcoeff or qcoeff buffer.  The encoder would
      populate the dc coeffs of the y blocks as a separate
      stage (recon_dcblock) and the decoder would use a special
      version of the idct.  This change eliminates the extra copy
      and reduces the code footprint.
      
      [Tero] Added needed changes to armv6 and NEON assembly.
