| 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.opus-codec.org/opus.git |
| % cd opus |
| |
| 2) Compile |
| |
| % ./autogen.sh |
| % ./configure |
| % 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) |
