      stream_encoder : Improve selection of residual accumulator width · f081524c
      Miroslav Lichvar authored and Erik de Castro Lopo's avatar Erik de Castro Lopo committed
      In the precompute_partition_info_sums_ function, instead of selecting
      64-bit accumulator when the signal bps is larger than 16, revert to the
      original approach based on partition size, but make room for few extra
      bits to not overflow with unusual signals where the average residual
      magnitude may be larger than bps.
      It slightly improves the performance with standard encoding levels and
      16-bit files as the 17-bit side channel can still be processed with the
      32-bit accumulator and correctly selects the 64-bit accumulator with
      very large 16-bit partitions.
      This is related to commits 6f7ec60c and 187e596e

      test_libFLAC/md5.c : Fix the tests. · 74d81333
      Erik de Castro Lopo authored
      The previous version of this test worked on amd64 and powerpc64 but
      failed on armhf. Investigation show that the previous version of the
      test data was generated for a case where the ARRAY_LEN macro was
      exploiting undefined behaviour.
      Fix was ditching the ARRAY_LEN macro and then recalculating the
      target data.

      libFLAC/bitmath : Restore an ASSERT that was removed some time after 1.2.1. · a8567d4b
      Erik de Castro Lopo authored
      Restore a FLAC__ASSERT() to bitmath functions FLAC__bitmath_ilog2 and
      FLAC__bitmath_ilog2_wide functions. This prevents the return of an
      "undefined" value.

      libFLAC/lpc_intrin_sseN.c : Disambiguate macro names. · 9aa15464
      Erik de Castro Lopo authored
      Previously, the files lpc_intrin_sse2.c and lpc_intrin_sse41.c both defined
      macros RESIDUAL_RESULT and DATA_RESULT. This situation made it impossible
      to merge these files which we may do at some stage.

      libFLAC: CPUID detecion improvements. · 2c150525
      Erik de Castro Lopo authored
      According to docs, it's incorrect to just call CPUID with EAX=1.
      One must to ensure that this value is supported.
      CPUs that don't support CPUID level 1 are very old, but...
      if FLAC tests CPUID presence it should also test CPUID level support.
      Also the function FLAC__cpu_have_cpuid_asm_ia32 was simplified
      according to the docs at Intel website and in Wikipedia.

      flac: Fix channel order for mono files. · 99257e17
      Erik de Castro Lopo authored
      * The default channel mask for mono files was 0x0001 (front left) but it
        makes more sense to use 0x0004 (front center) for such files.
      * Also FLAC will accept not only mono WAV files with 0x0001 mask, but also
        with 0x0002 (requested at https://sourceforge.net/p/flac/bugs/390/)
        and 0x0004 (e.g. SoX creates mono files with this mask).
      * The comment about channel support was updated.
      * The error message
           "Use --channel-map=none option to store channels in current order; FLAC files
           must also be decoded with --channel-map=none to restore correct order."
        is misleading: FLAC never changes the order of channels.
        Decoding with this options also sets the channel mask of the resulting WAV
        file to 0. Without this option the mask is equal to the value of

      flac: Fix encoder and decode progress messages with --ogg. · 1d12d98e
      Erik de Castro Lopo authored
      Problem discussed here:
      The values for the interval between two updates (e->stats_mask,
      e->stats_frames_interval) were set ~10 years ago, and it is small
      for current CPUs. It was now been increased too (0x3f -> 0xff, etc).
      The update interval is still less than 1 second.

      flac : Fix handling of raw input option. · a5c3a37c
      Erik de Castro Lopo authored
      FLAC was silently ignoring options for raw input for encoding mode (but
      prints an error and aborts when _de_coding).
      This can lead to bug reports such as https://sourceforge.net/p/flac/bugs/389/
      FLAC now prints a message about options misuse for encoding mode.
      Help messages were also updated.
