To build this source code, simply type:
|
|
|
|
% make
|
|
|
|
If this does not work, or if you want to change the default configuration
|
|
(e.g., to compile for a fixed-point architecture), simply edit the options
|
|
in the Makefile.
|
|
|
|
An up-to-date implementation conforming to this standard is available in a
|
|
Git repository at https://gitlab.xiph.org/xiph/opus.git or on a website at:
|
|
https://opus-codec.org/
|
|
However, although that implementation is expected to remain conformant
|
|
with the standard, it is the code in this RFC that shall remain normative.
|
|
To build from the git repository instead of using this RFC, follow these
|
|
steps:
|
|
|
|
1) Clone the repository (latest implementation of this standard at the time
|
|
of publication)
|
|
|
|
% git clone https://gitlab.xiph.org/xiph/opus.git
|
|
% cd opus
|
|
|
|
2) Compile
|
|
|
|
% ./autogen.sh
|
|
% ./configure
|
|
% make
|
|
|
|
Once you have compiled the codec, there will be a opus_demo executable in
|
|
the top directory.
|
|
|
|
Usage: opus_demo [-e] <application> <sampling rate (Hz)> <channels (1/2)>
|
|
<bits per second> [options] <input> <output>
|
|
opus_demo -d <sampling rate (Hz)> <channels (1/2)> [options]
|
|
<input> <output>
|
|
|
|
mode: voip | audio | restricted-lowdelay
|
|
options:
|
|
-e : only runs the encoder (output the bit-stream)
|
|
-d : only runs the decoder (reads the bit-stream as input)
|
|
-cbr : enable constant bitrate; default: variable bitrate
|
|
-cvbr : enable constrained variable bitrate; default: unconstrained
|
|
-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
|
|
-forcemono : force mono encoding, even for stereo input
|
|
-dtx : enable SILK DTX
|
|
-loss <perc> : simulate packet loss, in percent (0-100); default: 0
|
|
|
|
input and output are little endian signed 16-bit PCM files or opus bitstreams
|
|
with simple opus_demo proprietary framing.
