This release splits the speex codec library and the speex DSP
library into separate source trees. Both projects received build-system
improvements, bugfixes, and cleanup. The speex codec's VBR tuning
was improved, while the speexdsp resampler got some NEON optimizations.
1.0.x versions. Pulseaudio (which I am working on) requires
this version; moreover, the 1.0.x releases are deprecated.
The ChangeLog is not kept up-to-date, but here are some highlights:
1.2rc1
--------
Again, this new releases brings many improvements. The RAM requirement for
wideband has gone down drastically (i.e. more than 2x). A new resampler
module has been added, providing arbitrary sampling rate conversion --
fast. The echo canceller has also been improved. A bug in 1.2beta1 that
made the echo canceller unstable has been fixed. The echo canceller should
now converge faster, be robust and tolerant of incorrect capture-playback
synchronisation. The preprocessor has also been greatly improved. Not only
should the quality be better, but it is now fully converted to
fixed-point. At last, early TriMedia support (incomplete) has been merged.
1.2beta3
--------
The most obvious change in this release is that all the non-codec
components (preprocessor, echo cancellation, jitter buffer) have been
moved to a new libspeexdsp library. Other changes include a new jitter
buffer algorithm and resampler improvements/fixes. This is also the first
release where libspeex can be built without any floating point support. To
do this, the float compatibility API must be disabled (--disable-float-api
or DISABLE_FLOAT_API) and the VBR feature must be disabled (--disable-vbr
or DISABLE_VBR).
1.2beta2
--------
This release adds support for acoustic echo cancellation with multiple
microphones and multiple loudspeakers. It also adds an API to decorrelate
loudspeaker signals to improve multi-channel performance. In the bugfix
department, there are fixes for a few bugs in the echo canceller, jitter
buffer and preprocessor. At this point, the API for 1.2 should be stable
and only a few very minor additions are planned.
file's sole purpose was to provide a dependency on pkg-config and set
some environment variables. Instead, turn pkg-config into a "tool"
in the tools framework, where the pkg-config wrapper automatically
adds PKG_CONFIG_LIBDIR to the environment before invoking the real
pkg-config.
For all package Makefiles that included pkg-config/buildlink3.mk, remove
that inclusion and replace it with USE_TOOLS+=pkg-config.
The main change with this release is that it includes API additions
from the 1.1.x branch (while being backward compatible), so that
transition from 1.0.x to 1.1.x can be made easier.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
* Headers are now in ${PREFIX}/include/speex/ (but a copy is still
in ${PREFIX}/include for compat reasons).
* Pseudo-gapless playback (i.e. playback has the same number of
samples)
* Fixed a potential bug (unconfirmed) that might cause a segfault
in special circumstances.
Also includes a shlib major bump, so update DEPENDS in buildlink3.mk.
In this bugfix release: a fix for a multithreading bug and a
correction for an underflow problem that could slow decoding
dramatically on x86 processors.
This release fixes several minor bugs that were found in version
1.0 as well as a major bug in the wideband encoding. This makes
files encoded with 1.0 play with lower quality on 1.0.1 decoders.
