      Increase chrow row alignment to 16 bytes. · 7d1b37cd
      Timothy B. Terriberry authored
      This is done by expanding luma row to 32-byte alignment, since
       there is currently a bunch of code that assumes that
       uv_stride == y_stride/2 (see, for example, vp8/common/postproc.c,
       common/reconinter.c, common/arm/neon/recon16x16mb_neon.asm,
       encoder/temporal_filter.c, and possibly others; I haven't done a
       full audit).
      It also uses replaces the hardcoded border of 16 in a number of
       encoder buffers with VP8BORDERINPIXELS (currently 32), as the
       chroma rows start at an offset of border/2.
      Together, these two changes have the nice advantage that simply
       dumping the frame memory as a contiguous blob produces a valid,
       if padded, image.

      Better allocate yuv buffers. · e9751d4b
      Fritz Koenig authored
      Previously allocated more memory than necessary for yuv buffers.
      This makes it harder to track bugs with reading uninitialized
      data.

      Increase static linkage, remove unused functions · 429dc676
      John Koleszar authored
      A large number of functions were defined with external linkage, even
      though they were only used from within one file. This patch changes
      their linkage to static and removes the vp8_ prefix from their names,
      which should make it more obvious to the reader that the function is
      contained within the current translation unit. Functions that were
      not referenced were removed.
      
      These symbols were identified by:
      
        $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \
          | sort | grep '^ *1 '

      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.

      Eliminate more warnings. · 97b766a4
      Timothy B. Terriberry authored
      This eliminates a large set of warnings exposed by the Mozilla build
       system (Use of C++ comments in ISO C90 source, commas at the end of
       enum lists, a couple incomplete initializers, and signed/unsigned
       comparisons).
      It also eliminates many (but not all) of the warnings expose by newer
       GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite
       without checking the return values).
      There are a few spurious warnings left on my system:
      
      ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used
       uninitialized in this function
      gcc seems to be unable to figure out that the value shortcut doesn't
       change between the two if blocks that test it here.
      
      ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned
       expression >= 0 is always true
      ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned
       expression >= 0 is always true
      This is true, so far as it goes, but it's comparing against an enum,
       and the C standard does not mandate that enums be unsigned, so the
       checks can't be removed.

      cosmetics: trim trailing whitespace · 94c52e4d
      John Koleszar authored
      When the license headers were updated, they accidentally contained
      trailing whitespace, so unfortunately we have to touch all the files
      again.
