* AMR: add function to check speech framesMax2016-09-281-0/+21
| | | | | | | | Add convenience function osmo_amr_is_speech() to check if given AMR frame is speech frame: non-speech frames often require special processing. Change-Id: Ifaab02a2f581acc302b367d34fd2fc28a4d1e2e3
* Add functions to detect HR/FR SID framesMax2016-06-011-0/+3
| | | | | | | | | | | Add functions which check if given FR or HR frame (packed in RTP) contains SID (SIlence Descriptor) and corresponding tests.

* Add helper functions for AMR codecMax2016-05-311-0/+31
| | | | | | | | | | | | | | | | | | | * add functions to encode/decode various codec paramters from RTP payload with AMR frame according to RFC 4867 * those functions are extended version based on code from osmo-bts' amr.c by Andreas Eversberg * add corresponding enum types and strings for logging * add regression tests It's useful both to replace manual parsing in osmo-bts with fuctions covered by test suite and as a debugging helpers for issues related to AMR.

* codec: make data tables constant.Diego Elio Pettenò2012-06-301-12/+12
| | | | | | | | When declaring them constant, they are written on the .rodata section instead of .data, which means that they can be mapped directly from disk to memory. Signed-off-by: Diego Elio Pettenò <flameeyes@flameeyes.eu>
* build: simplify headers management and remove recursionDiego Elio Pettenò2012-06-301-3/+0
| | | | | | | | | | | | There is no real reason to keep the include directory a multi-level recursion, so instead declare everything within include (so that we can use proper nobase_ declarations) and be it. Please note that since we removed the sub-Makefile.am, ./configure will not create the directory structure for us on out-of-tree builds, so we have to make sure the directory we're generating to exists first.
