./audio/flac, Free lossless audio codec

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.3.2, Package name: flac-1.3.2, Maintainer: pkgsrc-users

FLAC stands for Free Lossless Audio Codec. Grossly oversimplified, FLAC is
similar to MP3, but lossless. The FLAC project consists of:
* the stream format
* libFLAC, which implements reference encoders and decoders
* flac, a command-line wrapper around libFLAC to encode and decode .flac
* input plugins for various music players (Winamp, XMMS, and more in the

"Free" means that the specification of the stream format is in the public
domain (the FLAC project reserves the right to set the FLAC specification
and certify compliance), and that neither the FLAC format nor any of the
implemented encoding/decoding methods are covered by any patent. It also
means that the source for libFLAC is available under the LGPL and the
sources for flac and the plugins are available under the GPL.

Log message:
FLAC 1.3.2:
* Fix undefined behaviour using GCC/Clang UBSAN (erikd).
* General hardening via fuzz testing with AFL (erikd and others).
* General code improvements (lvqcl, erikd and others).
* Add FLAC in MP4 specification docs (Ralph Giles).
* MSVS build cleanups (lvqcl).
* Fix some cppcheck warnings (erikd).
* Assume all currently used OSes support SSE2.

* Fix potential infinite loop on flac-to-flac conversion (erikd).
* Add WAVEFORMATEXTENSIBLE to WAV (as needed) when decoding (lvqcl).
* Only write vorbis-comments if they are non-empty.
* Error out if decoding RAW with bits != (8|16|24).

* Add --scan-replay-gain option.

build system:
* Fixes for MSVC and Makefile.lite build systems.

* CPU detection cleanup and fixes (Julian Calaby, erikd and lvqcl).
* Fix two stream decoder bugs (Max Kellermann).
* Fix a NULL dereference bug (on a malformed file).
* Changed the LPC order guess for a slight compression improvement, particularly \ 
for classical music (Martijn van Beurden).
* Improved encoding speed on older Intel CPUs.
* Fixed a seeking bug when decoding certain files (Miroslav Lichvar).
* Put an upper bound (32768) on the number of seek points.
* Fix potential memory leaks.
* Support 64bit brword/bwword allowing FLAC__BYTES_PER_WORD to be set to 8 \ 
(disabled by default).
* Fix an out-of-bounds heap read.
* Win32: Only use large buffers when writing to disk.

Log message:
Add SHA512 digests for distfiles for audio category

Problems found with existing distfiles:
No changes made to these file.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

for IA32 architecture.
* Faster encoding using SSE and AVX.
* Fixed bartlett, bartlett_hann and triangle functions.
* New apodization functions partial_tukey and punchout_tukey for improved \
