      Remove av1_cost_bit() · 751a2335
      Hui Su authored
      It's more efficient to use av1_cost_literal() instead.

      Change tilesize to 256x256 for >CIF resolutions · 5f7f3677
      Debargha Mukherjee authored
      An improvement in coding efficiency for higher resolution
      sources. Plus having this on by default will guard against
      256x256 LRU support not being inadvertently broken.

      Remove Frame_ID_NUMBERS_PRESENT_FLAG · 6eb9da2c
      Yaowu Xu authored
      This commit replaces hard coded FRAME_ID_NUMBERS_PRESENT_FLAG with
      error_resilient_mode, which properly reflects the intention of the
      experiment, i.e. "signal the complete state of the reference buffer
      explicitly for each frame" to deal with possible frame losses.

      add scalability experiment · 2eeadab1
      Soo-Chul Han authored
      configure:  --enable-experimental --enable-scalability
      
      New applications:  scalable_encoder, scalable_decoder
      
      scalable_encoder:
        * Encodes inputs as 2-layer (same size) stream
        * Encodes as obu file (OBU_NO_IVF must be enabled)
        * Base layer encoded in IPPPP where P's reference
          only the previous (in time) base layer
        * Enhancement layer encoded using its base layer as
          sole reference frame
        * Base layer encoded with fixed high QP
        * Enhancement layer encoded with fixed low QP
      
      scalable_decoder:
        * Able to decode scalable stream generated by
          scalable_encoder
        * Able to decode any single-layer stream encoded
          by aomenc
        * Outputs base layer as out_lyr0.yuv, and enhancement
          layer (if they exist) as out_lyrN.yuv (N = 1, 2, 3, ..)
        * Able to decode N layers (more than 2)

      Added a test for monochrome encoding. · 26ac0478
      Imdad Sardharwalla authored
      The test encodes 5 frames of a video using the --monochrome flag and
      verifies that the decoded frames satisfy:
      
      - each frame's monochrome flag is set to 1
      - each frame's U and V planes are set to a constant, and this constant
        is the same for all decoded frames
      - the initial frame's Y PSNR value is 'high enough'
      - the Y PSNR values remain fairly constant across all of the frames

      Don't calculate chroma data in monochrome mode · af8e2648
      Imdad Sardharwalla authored
      Encoder: Prior to this patch, some chroma data was calculated and
      later discarded when in monochrome mode. This patch ensures that
      the chroma planes are left uninitialised and that chroma
      calculations are not performed.
      
      Decoder: Prior to this patch, some chroma calculations were still
      being performed in monochrome mode (e.g. loop filtering). This
      patch ensures that calculations are only performed on the y
      plane, with the chroma planes being set to a constant.

      Fix Valgrind warning in av1_pick_filter_restoration · b08544de
      Imdad Sardharwalla authored
      Some array elements were defined and left uninitialised. This wasn't causing a
      problem, as the elements were later ignored, but it did cause Valgrind to
      produce warnings.
      
      The function now initialises the full array immediately after its definition in
      order to quiet these warnings.

      Reorder operation to avoid UBsan warning · 6394f0fd
      Yaowu Xu authored
      The original order of operations lead to all variables upgraded to
      unsigned int during computation, and enc->cnt being negative then
      would cause UBsan warning.
