      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.

      Changing decoder input partition API to input fragments. · 14272052
      Stefan Holmer authored
      Adding support for several partitions within one input fragment.
      This is necessary to fully support all possible packetization
      combinations in the VP8 RTP profile. Several partitions can
      be transmitted in the same packet, and they can only be split
      by reading the partition lengths from the bitstream.

      Added the ability to create rate-targeted, temporally
      scalable, VP8 compatible bitstreams.
      
      The application vp8_scalable_patterns.c demonstrates how
      to use this capability. Users can create output bitstreams
      containing upto 5 temporally separable streams encoded
      as a single VP8 bitstream.

      Since this is the only ABI incompatible change since the last release,
      convert it to use the control interface instead. The member of the

      More significant API changes were expected to be forthcoming when this

      it's not worth breaking compatibility for only this change.

      Disable __longjmp_chk protection · b73a3693
      John Koleszar authored
      glibc implements some checking on longjmp() calls by replacing it with
      an internal function __longjmp_chk(), when FORTIFY_SOURCE is defined.
      This can be problematic when compiling the library under one version of
      glibc and running it under another. Work around this issue for the one
      symbol affected for now, before taking out the undef hammer.

      New ways of passing encoded data between encoder and decoder. · 7296b3f9
      Stefan Holmer authored
      With this commit frames can be received partition-by-partition
      from the encoder and passed partition-by-partition to the
      decoder.
      
      At the encoder-side this makes it easier to split encoded
      frames at partition boundaries, useful when packetizing
      frames. When VPX_CODEC_USE_OUTPUT_PARTITION is enabled,
      several VPX_CODEC_CX_FRAME_PKT packets will be returned
      from vpx_codec_get_cx_data(), containing one partition
      each. The partition_id (starting at 0) specifies the decoding
      order of the partitions. All partitions but the last has
      the VPX_FRAME_IS_FRAGMENT flag set.
      
      At the decoder this opens up the possibility of decoding partition
      N even though partition N-1 was lost (given that independent
      partitioning has been enabled in the encoder) if more info
      about the missing parts of the stream is available through
      external signaling.
      
      Each partition is passed to the decoder through the
      vpx_codec_decode() function, with the data pointer pointing
      to the start of the partition, and with data_sz equal to the
      size of the partition. Missing partitions can be signaled to
      the decoder by setting data != NULL and data_sz = 0. When
      all partitions have been given to the decoder "end of data"
      should be signaled by calling vpx_codec_decode() with
      data = NULL and data_sz = 0.
      
      The first partition is the first partition according to the
      VP8 bitstream + the uncompressed data chunk + DCT address
      offsets if multiple residual partitions are used.

      The error-concealer is plugged in after any motion vectors have been

      Change rc undershoot/overshoot semantics · c99f9d7a
      John Koleszar authored
      This patch changes the rc_undershoot_pct and rc_overshoot_pct controls
      to set the "aggressiveness" of rate adaptation, by limiting the
      amount of difference between the target buffer level and the actual
      buffer level which is applied to the target frame rate for this frame.
      
      This patch was initially provided by arosenberg at logitech.com as
      an attachment to issue #270. It was modified to separate these controls
      from the other unrelated modifications in that patch, as well as to
      use the pre-existing variables rather than introducing new ones.

      Implement error tracking in the decoder · 67fb3a51
      Henrik Lundin authored
      A new vpx_codec_control called VP8D_GET_FRAME_CORRUPTED. The output
      from the function is non-zero if the last decoded frame contains
      corruption due to packet losses.
      
      The decoder is also modified to accept encoded frames of zero length.
      A zero length frame indicates to the decoder that one or more frames
      have been completely lost. This will mark the last decoded reference
      buffer as corrupted. The data pointer can be NULL if the length is
      zero.

      CQ Mode · e0846c9c
      Paul Wilkins authored
      The merge includes hooks to for CQ mode and other code
      changes merged from the test branch.
      
      CQ mode attempts to maintain a more stable quantizer within a clip
      whilst also trying to adhere to a guidline maximum bitrate.
      
      The existing target data rate parameter is used to specify the
      guideline maximum bitrate.
      
      A new parameter allows the user to specify a target CQ level.
      
      For normal (non kf/gf/arf) frames, the quantizer will not drop BELOW the
      user specified value (0-63). However, in some cases the encoder may
      choose to impose a target CQ that is above that specified by the user,
      if it estimates that consistent use of the target value is not compatible
      with guideline maximum bitrate.

      Add psnr/ssim tuning option · b0da9b39

      Two tunings are provided by this patch, PSNR (default) and SSIM.
      Activity masking is made dependent on setting --tune=ssim, as the
      current implementation hurts speed (10%) and PSNR (2.7% avg,
      10% peak) too much for it to be a default yet.

      This patch adds support for building shared libraries when configured
      with the --enable-shared switch.
      
      Building DLLs would require more invasive changes to the sample
      utilities than I want to make in this patch, since on Windows you can't
      use the address of an imported symbol in a static initializer. The best
      way to work around this is proably to build the codec interface mapping
      table with an init() function, but dll support is of questionable value
      anyway, since most windows users will probably use a media framework
      lib like webmdshow, which links this library in staticly.
