1 | Library: libwmavoice | ||
2 | Imported: 2010-08-07 by Mohamed Tarek | ||
3 | |||
4 | This set of files form the files needed from ffmpeg's libavcodec and libavutil | ||
5 | to build a standalone wma voice decoder. | ||
6 | |||
7 | LICENSING INFORMATION | ||
8 | |||
9 | ffmpeg is licensed under the Lesser GNU General Public License and the file | ||
10 | wmavoice.c is copyright (c) 2009 Ronald S. Bultje. | ||
11 | |||
12 | IMPORT DETAILS | ||
13 | |||
14 | Based on ffmpeg svn r24734 dated 7 August 2010. | ||
15 | |||
16 | As of 7 August 2010, libwmavoice contains just the files from ffmpeg with | ||
17 | minimum modifications to compile standalone. | ||
18 | |||
19 | COMPILING | ||
20 | |||
21 | the decoder can be compiled by issuing the "make" command from witin the | ||
22 | libwmavoice directory in any unix-line environment. | ||
23 | |||
24 | To test the decoder in the rockbox simulator, cd to libwmavoice directory then | ||
25 | execute the following command to enable building wma voice: | ||
26 | patch -p 0 < wmavoice_mainbuild.patch | ||
