* Include codec.h file from codec C filesHarald Welte2017-06-093-0/+3
| | | | | | | failure to do so would prevent the compiler from catching inconsistencies between declaration and definition. Change-Id: I88617c97adcff328292e501fd5d254eeae96a660
* osmo_{fr,hr}_check_sid(): Use const input argumentHarald Welte2017-06-092-4/+4

* Fix wrongful GSM FR codec SID frame detection in DTX.Jean-Francois Dionne2017-06-091-10/+10
| | | | | | | | Based on ETSI TS 101 318 section 5.1.2 the 95 bits SID code word is not detected correctly due to a wrongful offset in the bits location indexes. Change-Id: I45d98c6edf267f313883503a65385190ffbc65ca
* add libpseudotalloc as super-simplistic talloc replacementHarald Welte2017-05-171-0/+5
| | | | | | | | | | | In tightly embedded builds (--enable-embedded), we want the ability to replace talloc with a very simple heap allocator to avoid the complexity of talloc without modifying all our code that assumes talloc. This will break the hierarchical notion of the allocator, but libosmo{core,gsm,coding,codec} don't rely on that anyway. Change-Id: Ie341034076f242a813f081919dd09d845775ad35
* DTX: fix AMR SID-FIRST detectionJean-Francois Dionne2017-01-101-2/+2
| | | | | | | Max's note: adjusted test output. Change-Id: I46477c631bf86345cb757f31d7f2e2935b12adcc Related: OS#1801
* Catch-up with git version tagsMax2016-12-211-1/+2
| | | | | | | | | | | | * update debian/changelog * update TODO-RELEASE * add comments to Makefile.am and TODO-RELEASE to simplify the process in future * add link to libtool docs to Makefile.am to simplify LIBVERSION maintenance Related: OS#1861 Change-Id: I22c257e357f597519120232d742d6a61289db021
* Add null-pointer check to osmo_amr_rtp_dec()Max2016-11-071-3/+3
| | | | | | | Check that RTP payload we're about to decode is not NULL and return proper error code instead of segfaulting. Add corresponding test case. Change-Id: Ib6cda9900a41ed16bbfbde9df3de9d38e0a7469b
* libosmocodec link fix on MacOSXAnatoly Orlov2016-09-091-0/+1

* Add functions to detect HR/FR SID framesMax2016-06-012-0/+71
| | | | | | | | | | | 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 codecMax2016-05-312-1/+107
| | | | | | | | | | | | | | | | | | | * 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.

* build: remove unused all_includes and use AM_CPPFLAGSJan Engelhardt2014-10-031-1/+2
| | | | | Preprocessor flags are best placed in AM_CPPFLAGS. Remove use of the unused all_includes variable, which is never set.
* cygwin: Link many libraries with -no-undefined to create a dllHolger Hans Peter Freyther2013-03-031-1/+1
| | | | | | Only the Gb library relies on having undefined references to a symbol that needs to be provided by the host application. For all other libraries we can link with -no-undefined.
* codec: Fix the GSM 06.20 ordering tablesSylvain Munaut2013-03-011-41/+41
| | | | | | | | | | Seems the script I used to parse those had a bug where range of bits in the 'decreasing' direction ( like 6..0 ) were not processed properly. Thanks to Andreas for noticing this ! Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

* build: use LT_INIT(pic-only) instead of forcing -fPIC.Diego Elio Pettenò2012-06-301-1/+1
| | | | | | | | This actually allows for the user to override the decision and at the same time supports compilers that might not be able to use -fPIC at all. Signed-off-by: Diego Elio Pettenò <flameeyes@flameeyes.eu>
* codec: make data tables constant.Diego Elio Pettenò2012-06-304-12/+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>
