| Jean-Marc Valin | 445d5f4 | 2011-03-09 14:15:32 -0500 | [diff] [blame] | 1 | To build this source code, simply type: |
| 2 | |
| 3 | % make |
| 4 | |
| 5 | If this does not work, or to change the default configuration (e.g. compile for |
| 6 | a fixed-point architecture), simply edit the options in the Makefile |
| 7 | |
| 8 | To build from the git repository instead of using this draft, the following |
| 9 | steps are necessary |
| 10 | |
| 11 | 1) Clone the repository: |
| 12 | |
| 13 | % git clone git://git.xiph.org/users/jm/ietfcodec.git |
| 14 | % cd ietfcodec |
| 15 | |
| 16 | 2) Get the celt and silk submodules: |
| 17 | |
| 18 | % git submodule update --init |
| 19 | |
| 20 | 3) Compile |
| 21 | |
| 22 | % ./autogen.sh |
| 23 | % ./configure --disable-shared |
| 24 | % make |
| 25 | |
| 26 | |
| 27 | Once you have compiled the codec, there will be a test_opus executable in |
| 28 | the src/ directory. This can be in the following way: |
| 29 | |
| 30 | % ./test_opus <mode (0/1/2)> <sampling rate (Hz)> <channels> <bits per second> [options] <input> <output> |
| 31 | |
| 32 | mode: 0 for audo, 1 for voice, 2 for audio: |
| 33 | options: |
| 34 | -cbr : enable constant bitrate; default: VBR |
| 35 | -bandwidth <NB|MB|WB|SWB|FB> : audio bandwidth (from narrowband to fullband); default: sampling rate |
| 36 | -framesize <2.5|5|10|20|40|60> : frame size in ms; default: 20 |
| 37 | -max_payload <bytes> : maximum payload size in bytes, default: 1024 |
| 38 | -complexity <comp> : complexity, 0 (lowest) ... 10 (highest); default: 10 |
| 39 | -inbandfec : enable SILK inband FEC |
| 40 | -dtx : enable SILK DTX |
| 41 | -loss <perc> : simulate packet loss, in percent (0-100); default: 0 |
| 42 | |
| 43 | input and output are 16-bit PCM files (machine endian) |
