      Avoid setting rate multiplier as 0 · 697a8e6f
      hui su authored
      In high bitdepth setting, the rate multipier may be set as 0. In
      lossless mode, the RD cost would always be 0, resulting in bad
      partition and prediction mode choices.

      With the sad functions, and hopefully the variance functions soon,
      moving to the vpx_dsp location, place the defines used in the
      reference C code in a common location.

      This is also an intermediate step towards adding back the

      Make encoder buffer allocation dynamic · 3807dd82
      Adrian Grange authored
      Frame buffers are now allocated dynamically on-demand.
      
      Entries in the reference frame map, cm->ref_frame_map,
      may now be set to -1 (INVALID_IDX) to indicate that
      there is not a valid reference buffer in that "slot".
      
      All slots in the reference frame map are now initialized
      to the empty state (-1) and each buffer is initialized
      to have a reference count of 0.

      Try again to merge branch 'frame-parallel' into master branch. · be6aeada
      hkuang authored
      In frame parallel decode, libvpx decoder decodes several frames on all
      cpus in parallel fashion. If not being flushed, it will only return frame
      when all the cpus are busy. If getting flushed, it will return all the
      frames in the decoder. Compare with current serial decode mode in which
      libvpx decoder is idle between decode calls, libvpx decoder is busy
      between decode calls.
      
      Current frame parallel decode will only speed up the decoding for frame
      parallel encoded videos. For non frame parallel encoded videos, frame
      parallel decode is slower than serial decode due to lack of loopfilter
      worker thread.
      
      There are still some known issues that need to be addressed. For example:
      decode frame parallel videos with segmentation enabled is not right sometimes.
      
      * frame-parallel:
        Add error handling for frame parallel decode and unit test for that.
        Fix a bug in frame parallel decode and add a unit test for that.
        Add two test vectors to test frame parallel decode.
        Add key frame seeking to webmdec and webm_video_source.
        Implement frame parallel decode for VP9.
        Increase the thread test range to cover 5, 6, 7, 8 threads.
        Fix a bug in adding frame parallel unit test.
        Add VP9 frame-parallel unit test.
        Manually pick "Make the api behavior conform to api spec." from master branch.
        Move vp9_dec_build_inter_predictors_* to decoder folder.
        Add segmentation map array for current and last frame segmentation.
        Include the right header for VP9 worker thread.
        Move vp9_thread.* to common.
        ctrl_get_reference does not need user_priv.
        Seperate the frame buffers from VP9 encoder/decoder structure.

      vp9_ethread: modify VP9_COMP structure · edbd61e1
      Yunqing Wang authored
      This patch modified struct VP9_COMP. Created a struct ThreadData
      to include data that need to be copied for each thread. In
      multiple thread case, one thread processes one tile. all threads
      share one copy of VP9_COMP,
      (refer to VP9_COMP *cpi in the code)
      but each thread has its own copy of ThreadData,
      (refer to ThreadData *td in the code).
      Therefore, within the scope of encode_tiles(), both cpi and td
      need to be passed as function parameters.
      
      In single thread case, the FRAME_COUNTS pointer in ThreadData
      points to "counts" in VP9_COMMON.

      Remove mi_grid_* structures. · c70cea97
      hkuang authored
      mi_grid_* are arrays of pointer to pointer. They save the pointers that point
      to the MIs in cm->mi. But they are unnecessary and complicated. The original
      goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer
      inside MODE_INFO_t, same goal could be achieved.
      
      This commit totally removes the mi_grid_* structures. But there are still
      many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit
      will do on-demand MODE_INFO_t allocation in order to save these memories.
