[M] Change in libosmocore[master]: codec: add osmo_efr_check_sid() function

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/32034 ) Change subject: codec: add osmo_efr_check_sid() function ...................................................................... codec: add osmo_efr_check_sid() function Previously existing code provides osmo_fr_check_sid() and osmo_hr_check_sid() functions for FR1 and HR1 codecs; these functions are used by various RTP-touching programs in the Osmocom CNI suite when they need to differentiate between speech and SID frames. However, there was no corresponding function of this form for EFR codec, with the result being that the same programs that handle speech vs SID distinction correctly for FR1 and HR1 fail to do so for EFR. The present change adds an osmo_efr_check_sid() function to libosmocodec that fully mirrors previously existing osmo_fr_check_sid() and osmo_hr_check_sid(), providing the first step toward more correct EFR handling in programs where a SID check may be needed.
