      vpxenc: initial implementation of multistream support · 9e50ed7f
      John Koleszar authored
      Add the ability to specify multiple output streams on the command line.
      Streams are delimited by --, and most parameters inherit from previous
      streams.
      
      In this implementation, resizing streams is still not supported. It
      does not make use of the new multistream support in the encoder either.
      Two pass support runs all streams independently, though it's
      theoretically possible that we could combine firstpass runs in the
      future. The logic required for this is too tricky to do as part of this
      initial implementation. This is mostly an effort to get the parameter
      passing and independent streams working from the application's
      perspective, and a later commit will add the rescaling and
      multiresolution support.

      Fix variance overflow · fea3556e
      Johann authored
      In the variance calculations the difference is summed and later squared.
      When the sum exceeds sqrt(2^31) the value is treated as a negative when
      it is shifted which gives incorrect results.
      
      To fix this we cast the result of the multiplication as unsigned.
      
      The alternative fix is to shift sum down by 4 before multiplying.
      However that will reduce precision.
      
      For 16x16 blocks the maximum sum is 65280 and sqrt(2^31) is 46340 (and
      change).
      
      PPC change is untested.

      Align internal mfqe framebuffer dimensions · 417b8529
      John Koleszar authored
      MFQE postproc crashed with stream dimensions not a multiple of 16.
      The buffer was memset unconditionally, so if the buffer allocation
      fails we end up trying to write to NULL.
      
      This patch traps an allocation failure with vpx_internal_error(),
      and aligns the buffer dimensions to what vp8_yv12_alloc_frame_buffer()
      expects.

      Allow to skip highest-resolution encoding in multi-resolution encoder · fa1a9290
      Yunqing Wang authored
      Sometimes, a user doesn't have enough bandwidth to send high-resolution
      (i.e. HD) video even though the camera catches HD video. This change
      allowed users to skip highest-resolution encoding by setting that level's
      target bit rate to 0.
      
      To test it, modify the following line in vp8_multi_resolution_encoder.c.
          unsigned int  target_bitrate[NUM_ENCODERS]={1400, 500, 100};
      To skip the highest-resolution level, change it to
          unsigned int  target_bitrate[NUM_ENCODERS]={0, 500, 100};
      To skip the first and second highest resolution levels, change it to
          unsigned int  target_bitrate[NUM_ENCODERS]={0, 0, 100};
      
      This change also fixed a small problem in mapping, which slightly helped
      quality and performance.

      John Koleszar authored
      This is the final commit in the series converting to the new RTCD
      system. It removes the encoder csystemdependent files and the remaining
      global function pointers that didn't conform to the old RTCD system.

      New RTCD implementation · a910049a
      John Koleszar authored
      This is a proof of concept RTCD implementation to replace the current
      system of nested includes, prototypes, INVOKE macros, etc. Currently
      only the decoder specific functions are implemented in the new system.
      Additional functions will be added in subsequent commits.
      
      Overview:
        RTCD "functions" are implemented as either a global function pointer
        or a macro (when only one eligible specialization available).
        Functions which have RTCD specializations are listed using a simple
        DSL identifying the function's base name, its prototype, and the
        architecture extensions that specializations are available for.
      
      Advantages over the old system:
        - No INVOKE macros. A call to an RTCD function looks like an ordinary
          function call.
        - No need to pass vtables around.
        - If there is only one eligible function to call, the function is
          called directly, rather than indirecting through a function pointer.
        - Supports the notion of "required" extensions, so in combination with
          the above, on x86_64 if the best function available is sse2 or lower
          it will be called directly, since all x86_64 platforms implement
          sse2.
        - Elides all references to functions which will never be called, which
          could reduce binary size. For example if sse2 is required and there
          are both mmx and sse2 implementations of a certain function, the
          code will have no link time references to the mmx code.
        - Significantly easier to add a new function, just one file to edit.
      
      Disadvantages:
        - Requires global writable data (though this is not a new requirement)
        - 1 new generated source file.
