| Jean-Marc Valin | 4468c75 | 2010-07-08 13:40:07 -0400 | [diff] [blame] | 3 | To build from a distribution tarball, you only need to do the following: |
| Jean-Marc Valin | 8ba2a77 | 2010-07-05 14:55:02 -0400 | [diff] [blame] | 4 | |
| Jean-Marc Valin | 8ba2a77 | 2010-07-05 14:55:02 -0400 | [diff] [blame] | 5 | % ./configure --disable-shared |
| Jean-Marc Valin | 8ba2a77 | 2010-07-05 14:55:02 -0400 | [diff] [blame] | 6 | % make |
| 7 | |
| Jean-Marc Valin | 4468c75 | 2010-07-08 13:40:07 -0400 | [diff] [blame] | 8 | To build from the git repository, the following steps are necessary |
| 9 | |
| 10 | 0) Clone the repository: |
| 11 | |
| 12 | % git clone git://git.xiph.org/users/jm/ietfcodec.git |
| 13 | % cd ietfcodec |
| 14 | |
| 15 | 1) Get the celt and silk submodules: |
| 16 | |
| 17 | % git submodule update --init |
| 18 | |
| 19 | 2) Compiling |
| 20 | |
| 21 | % ./autogen.sh |
| 22 | % ./configure --disable-shared |
| 23 | % make |
| 24 | |
| 25 | |
| Jean-Marc Valin | 05dd36a | 2010-10-18 12:50:49 -0400 | [diff] [blame^] | 26 | Once you have compiled the codec, there will be a test_opus executable in |
| Jean-Marc Valin | 4468c75 | 2010-07-08 13:40:07 -0400 | [diff] [blame] | 27 | the src/ directory. This can be in the following way: |
| 28 | |
| Jean-Marc Valin | 05dd36a | 2010-10-18 12:50:49 -0400 | [diff] [blame^] | 29 | % ./test_opus 48000 1 960 80 input.sw output.sw |
| Jean-Marc Valin | 4468c75 | 2010-07-08 13:40:07 -0400 | [diff] [blame] | 30 | |
| 31 | The arguments are: |
| 32 | 1) The sampling rate (only 48000 supported for now) |
| 33 | 2) The number of channels (only mono supported for now) |
| 34 | 3) The frame size in samples (480 and 960 supported) |
| Jean-Marc Valin | 78a4b58 | 2010-07-08 15:51:49 -0400 | [diff] [blame] | 35 | 4) Number of compressed bytes per frame (80 here means 32 kb/s) |
| 36 | 5) Input PCM file (16-bit, machine endian) |
| 37 | 6) Output PCM file after encoding and decoding (16-bit machine endian) |
