Bcg729 is an opensource implementation of both encoder and decoder of the ITU G729 Annex A/B speech codec.
The library written in C 99 is fully portable and can be executed on many platforms including both ARM and x86 processors. libbcg729 supports concurrent channels encoding/decoding for multi call application such as conferencing.

No dependency is requested.
Building by Autotools way is deprecated. Use CMake to configure the source code.
cmake . -DCMAKE_INSTALL_PREFIX=<prefix> -DCMAKE_PREFIX_PATH=<search_prefixes>
make
make install
CMAKE_INSTALL_PREFIX=<string>: install prefixCMAKE_PREFIX_PATH=<string>: column-separated list of prefixes where to look for dependenciesENABLE_UNIT_TESTS=NO: do not build non-regression tests
Our CMake scripts may automatically add some paths into research paths of generated binaries.
To ensure that the installed binaries are striped of any rpath, use -DCMAKE_SKIP_INSTALL_RPATH=ON
while you invoke cmake.
-
Tests are defined for each functional bloc (more or less matching a source file) and for global encoding/decoding
-
Use
-DENABLE_TESTS=YESto compile with tests To run all tests available in the test directory, run testCampaignAll from test directory -
Input tests pattern have been generated by ITU code using ITU tests patterns. The test patterns are not part of this repository but can be downloaded here. However, the first run of
make checkwill get them for you. -
To run partial test, use perl executable
