      tests: add a shorter 720p test clip · 7839d038
      James Zern authored
      niklas_1280_720_30.y4m 60 frames @ 30fps
      only a small number of frames are being used; this reduces the test data
      download size in non-perf-test cases by >500M.
      retain niklas_1280_720_30.yuv for encode+decode perf tests

      vp9: fix segfault w/corrupt data post frame-parallel merge · 0261fb4c
      James Zern authored
      cm->frame_bufs[].idx values were made consistent in:
      61c5e94e Use -1 consistently as invalid buffer idx
      update the initialization in swap_frame_buffers() to match.
      additionally:
        - remove some shadowed variables in the former and marked them volatile

      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.

      Modify the frame context memory deallocation · 12284334
      Yunqing Wang authored
      This patch was to fix the vpxdec fuzzing3 test failure. When an
      error occurs, setjmp() is invoked, which calls the decoder
      removing routine. In multiple thread situation, other threads
      could try to access the frame context memory that is already
      deallocated, thus causing a segfault.
      
      An invalid unit test was added for this issue.

      vp9: correct context buffer resize check · bb4950df
      James Zern authored
      allocations within vp9_alloc_context_buffers() rely on mi_rows/mi_cols
      individually, use those to determine whether to realloc rather than
      stride and stride * rows. this fixes a crash with some fuzzed files for
      invalid accesses into last_frame_seg_map and above_context.

      Fix reference frame size restrictions. · 899585eb
      Jim Bankoski authored
      The issue was introduced by commit g9f37d149 with adding explicit
      restrictions on reference-frame scale factors. The restriction
      is checked against aligned-by-8 frame dimensions, not against
      original ones. So, for example, frame of 35×35 actually can refer
      to frame of 70×70, but the new check won't allow this. It will
      compare 35 vs 72 (not 70), so 2x downscale limit will be exceeded.

      This patch insures that the last byte of a chunk that contains a

      As part of doing that the file : vp90-2-15-fuzz-flicker.webm now fails
      to decode properly and moves to the invalid file test from the test
