To build this source code, simply type:
% make
If this does not work, or to change the default configuration (e.g. compile for
a fixed-point architecture), simply edit the options in the Makefile
To build from the git repository instead of using this draft, the following
steps are necessary
1) Clone the repository:
% git clone git://git.xiph.org/users/jm/ietfcodec.git
% cd ietfcodec
2) Get the celt and silk submodules:
% git submodule update --init
3) Compile
% ./autogen.sh
% ./configure --disable-shared
% make
Once you have compiled the codec, there will be a test_opus executable in
the src/ directory. This can be in the following way:
% ./test_opus <mode (0/1/2)> <sampling rate (Hz)> <channels> <bits per second> [options] <input> <output>
mode: 0 for audo, 1 for voice, 2 for audio:
options:
-cbr : enable constant bitrate; default: VBR
-bandwidth <NB|MB|WB|SWB|FB> : audio bandwidth (from narrowband to fullband); default: sampling rate
-framesize <2.5|5|10|20|40|60> : frame size in ms; default: 20
-max_payload <bytes> : maximum payload size in bytes, default: 1024
-complexity <comp> : complexity, 0 (lowest) ... 10 (highest); default: 10
-inbandfec : enable SILK inband FEC
-dtx : enable SILK DTX
-loss <perc> : simulate packet loss, in percent (0-100); default: 0
input and output are 16-bit PCM files (machine endian)
