      [svc] Finalize spatial svc first pass rate control · d2053350
      Minghai Shang authored
            1. Save stats for each spatial layer
            2. Add frame buffer management for svc first pass rc
            3. Set default spatial layer to 1
            4. Flush encoder at the end of stream in test app
      This only supports spatial svc.

      Add VP9 decoder support for external frame buffers · a4f30a50
      Frank Galligan authored
      Added support for external frame buffers to libvpx's VP9 decoder.
      If the external frame buffer functions are set then libvpx will
      call the get function whenever it needs a new frame buffer to
      decode a frame into. And it will call the release function
      whenever there are no more references to that buffer.

      Layer based rate control for CBR mode. · 6be2b750
      Marco Paniconi authored
      This patch adds a buffer-based rate control for temporal layers,
      under CBR mode.
      
      Added vpx_temporal_scalable_patters.c encoder for testing temporal
      layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).
      
      Updated datarate unittest with tests for temporal layer rate-targeting.

      Move SVC per-frame loop from sample app into libvpx proper · 1ed0e1be
      Ivan Maltz authored
      SVC multiple layer per frame encoding is invoked with vpx_svc_init and
      vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg.
      Additional improvements:
      - make dummy frame handling a bit more explicit
      - fixed bug with single layer encodes
      - track individual frame sizes and psnrs instead of averages
      - parameterized quantizer, 16th scalefactors, more logging,
      - enabled single layer encodes to generate baseline
      - include new mode for 3 layer I frame with 5 total layers

      Pack invisible frames without lengths · 64bcffc1
      John Koleszar authored
      Modify the decoder to return the ending position of the bool decoder and
      use that as the starting position for the next frame.
      
      The constant-space algorithm for parsing the appended frame lengths is
      O(n^2), which is a potential DoS concern if n is unbounded. Revisit
      the appended lengths for use as partition lengths when multipartition
      support is added.
      
      In addition, this allows decoding of raw streams outside of a container
      without additional framing information, though it's insufficient to
      be able to remux said stream into a container.

      Packing Altref along with succeeding frame and length encoding frames · bc9670ee
      Vignesh Venkatasubramanian authored
      The altref frame is packed along with the next P frame. So that
      outside of the codec there are now only two types of frames P and I.
      Also, now it is one frame in and one frame out with respect to the
      codec. Apart from that, all the frames are length encoded with the
      length of each frame appended to the frame itself. There are
      two categories of frames and each of them will look as follows:
      
        - Packed frames (an altref along with the succeeding p frame)
          - altref_frame_data | altref_lenngth | frame_data | length
        - Unpacked frames (all frames other than the above)
          - frame_data | length

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

      multi-res: restore v1.0.0 API · 25a36d6b
      John Koleszar authored
      Move the notion of 0 bitrate implying skip deeper into the codec,
      rather than doing it at the multi-encoder API level. This preserves
      v1.0.0 ABI compatibility, rather than forcing a bump to v2.0.0 over a
      minor change. Also, this allows the case where the application can
      selectively enable and disable the larger resolution(s) without having
      to reinitialize the codec instace (for instance, if no target is
      receiving the full resolution stream).
      
      It's not clear how deep to push this check. It may be valuable to
      allow the framerate adaptation code to run, for example. Currently put
      the check as early as possible for simplicity, should reevaluate this
      as this feature gains real use.

      WebM Experimental Codec Branch Snapshot · 6035da54
      Yaowu Xu authored
      This is a code snapshot of experimental work currently ongoing for a
      next-generation codec.
      
      The codebase has been cut down considerably from the libvpx baseline.
      For example, we are currently only supporting VBR 2-pass rate control
      and have removed most of the code relating to coding speed, threading,
      error resilience, partitions and various other features.  This is in
      part to make the codebase easier to work on and experiment with, but
      also because we want to have an open discussion about how the bitstream
      will be structured and partitioned and not have that conversation
      constrained by past work.
      
      Our basic working pattern has been to initially encapsulate experiments
      using configure options linked to #IF CONFIG_XXX statements in the
      code. Once experiments have matured and we are reasonably happy that
      they give benefit and can be merged without breaking other experiments,
      we remove the conditional compile statements and merge them in.
      
      Current changes include:
      * Temporal coding experiment for segments (though still only 4 max, it
        will likely be increased).
      * Segment feature experiment - to allow various bits of information to
        be coded at the segment level. Features tested so far include mode
        and reference frame information, limiting end of block offset and
        transform size, alongside Q and loop filter parameters, but this set
        is very fluid.
      * Support for 8x8 transform - 8x8 dct with 2nd order 2x2 haar is used
        in MBs using 16x16 prediction modes within inter frames.
      * Compound prediction (combination of signals from existing predictors
        to create a new predictor).
      * 8 tap interpolation filters and 1/8th pel motion vectors.
      * Loop filter modifications.
      * Various entropy modifications and changes to how entropy contexts and
        updates are handled.
      * Extended quantizer range matched to transform precision improvements.
      
      There are also ongoing further experiments that we hope to merge in the
      near future: For example, coding of motion and other aspects of the
      prediction signal to better support larger image formats, use of larger
      block sizes (e.g. 32x32 and up) and lossless non-transform based coding
      options (especially for key frames). It is our hope that we will be
      able to make regular updates and we will warmly welcome community
      contributions.
      
      Please be warned that, at this stage, the codebase is currently slower
      than VP8 stable branch as most new code has not been optimized, and
      even the 'C' has been deliberately written to be simple and obvious,
      not fast.
      
      The following graphs have the initial test results, numbers in the
      tables measure the compression improvement in terms of percentage. The
      build has  the following optional experiments configured:
      --enable-experimental --enable-enhanced_interp --enable-uvintra
      --enable-high_precision_mv --enable-sixteenth_subpel_uv

      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.

      Align image buffer in multiple-resolution encoder · 153eec46
      Yunqing Wang authored
      Aligned the image buffer and stride to 32 bytes. This enables
      calling of optimized scaler function in libyuv, and improves
      the performance.
      
      Tested libyuv scaler(x86 optimization) on Linux and Windows,
      including: Linux 32/64bit, visual studio 32/64bit, Cygwin, and
      MinGW32.
      
      Also, fixed a wrong pointer in vpx_codec_encode().
