      [spatial svc]Implement alt reference frames · e899859c
      Minghai Shang authored
      All changes are for spatial svc only.
      1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
      2. Use golden reference idx for spatial reference
      3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
      4. Add "auto-alt-refs" in svc options

      Enable vpxenc to specify internal coded frame size · f7bd1274
      Adrian Grange authored
      Added command line flags "resize-width" & "resize-height"
      to allow the user to specify the frame size to encode at.
      
      These two flags are ignored if the "resize-allowed" switch
      is not set to 1.
      
      All frames in the clip are then encoded at this size, which
      must be smaller than the raw frame size.

      Support a constant quality mode in VP9 · e378a89b
      Deb Mukherjee authored
      Adds a new end-usage option for constant quality encoding in vpx. This
      first version implemented for VP9, encodes all regular inter frames
      using the quality specified in the --cq-level= option, while encoding
      all key frames and golden/altref frames at a quality better than that.
      
      The current performance on derfraw300 is +0.910% up from bitrate control,
      but achieved without multiple recode loops per frame.
      
      The decision for qp for each altref/golden/key frame will be improved
      in subsequent patches based on better use of stats from the first pass.
      Further, the qp for regular inter frames may also be varied around the
      provided cq-level.

      Adds a flag to disable features that would inhibit frame parallel
      decoding. This includes backward adaptation and MV sorting based
      on search in ref frame buffer.
      
      Also includes some minor clean-ups.

      multi-res: add drop_frame support · 4066c8b2
      Yunqing Wang authored
      Added drop_frame support in multi-resolution encoder.
      
      If one frame is dropped at a lower-resolution level, the next
      upper-resolution level encoder needs to encode that frame
      independently without any lower-resolution level motion
      information.
      
      Another issue is that if one frame is dropped at some but not all
      resolution levels, a frame after that one may use different set
      of reference frames at different resolution levels. This reference
      frame asynchronization could degrade motion search precision in
      upper-resolution level encoding, which uses lower-resolution level
      motion result. This change compares the lower-resolution and upper-
      resolution level's reference frames. If they are not the same, the
      upper-resolution level encoder can not use lower-resolution level
      motion result.

      Added validity checking in multi-res encoder. Disable spatial

      Add lossless compression mode. · e44ee38a
      Hui Su authored
      This commit adds lossless compression capability to the experimental
      branch. The lossless experiment can be enabled using --enable-lossless
      in configure. When the experiment is enabled, the encoder will use
      lossless compression mode by command line option --lossless, and the
      decoder automatically recognizes a losslessly encoded clip and decodes
      accordingly.
      
      To achieve the lossless coding, this commit has changed the following:
          1. To encode at lossless mode, encoder forces the use of unit
      quantizer, i.e, Q 0, where effective quantization is 1. Encoder also
      disables the usage of 8x8 transform and allows only 4x4 transform;
          2. At Q 0, the first order 4x4  DCT/IDCT have been switched over
      to a pair of forward and inverse Walsh-Hadamard Transform
      (http://goo.gl/EIsfy),  with proper scaling applied to match the range
      of the original 4x4 DCT/IDCT pair;
          3. At Q 0, the second order remains to use the previous
      walsh-hadamard transform pair. However, to maintain the reversibility
      in second order transform at Q 0, scaling down is applied to first
      order DC coefficients prior to forward transform, and scaling up is
      applied to the second order output prior to quantization. Symmetric
      upscaling and downscaling are added around inverse second order
      transform;
          4. At lossless mode, encoder also disables a number of minor
      features to ensure no loss is introduced, these features includes:
              a. Trellis quantization optimization
              b. Loop filtering
              c. Aggressive zero-binning, rounding and zero-bin boosting
              d. Mode based zero-bin boosting
      
      Lossless coding test was performed on all clips within the derf set,
      to verify that the commit has achieved lossless compression for all
      clips. The average compression ratio is around 2.57 to 1.

      Remove threading dependencies with --disable-multithread · 8df79e9d
      John Koleszar authored
      Avoid a pthreads dependency via pthread_once() when compiled with
      --disable-multithread.
      
      In addition, this synchronization is disabled for Win32 as well, even
      though we can be sure that the required primatives exist, so that the
      requirements on the application when built with --disable-multithread
      are consistent across platforms.
      
      Users using libvpx built with --disable-multithread in a multithreaded
      context should provide their own synchronization. Updated the
      documentation to vpx_codec_enc_init_ver() and vpx_codec_dec_init_ver()
      to note this requirement. Moved the RTCD initialization call to match
      this description, as previously it didn't happen until the first
      frame.

      In multi-resolution encoding, frame_type decision for each frame

      and they are forced to use the same frame_type picked by the
      lowest-resolution encoder.
