[M] Change in osmo-bts[master]: RTP: make ortp optional at compile time

falconia has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bts/+/42197?usp=email ) Change subject: RTP: make ortp optional at compile time ...................................................................... RTP: make ortp optional at compile time It is now possible to run osmo-bts configure with --disable-ortp option, which makes it use only twrtp library (integrated into libosmo-netif) and removes all dependency on Belledonne software, such that osmo-bts can be built on top of libosmo-abis that has also been configured with its respective --disable-ortp option. TODO: contrib/ber/rtp_ber utility still uses ortp and has no support for twrtp or any other alternative - therefore, when osmo-bts is configured with --disable-ortp, this utility is not built.

[M] Change in osmo-bts[master]: RTP: add vty option for ortp vs twrtp selection
by falconia 25 Feb '26

25 Feb '26

falconia has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bts/+/42167?usp=email ) Change subject: RTP: add vty option for ortp vs twrtp selection ...................................................................... RTP: add vty option for ortp vs twrtp selection With this patch it finally becomes possible for the user to select which RTP library should be used: ortp or twrtp. ortp is still the default for now, in order to not alter behavior for existing installations until twrtp receives more real world testing by users beyond the original author. Future patches may change the default or even remove ortp support altogether - but twrtp should receive more testing as a user opt-in feature first.

[M] Change in osmo-bts[master]: RTP: use new abstraction layer instead of direct osmo_ortp
by falconia 25 Feb '26

25 Feb '26

falconia has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bts/+/42166?usp=email ) Change subject: RTP: use new abstraction layer instead of direct osmo_ortp ...................................................................... RTP: use new abstraction layer instead of direct osmo_ortp As of this patch in the series, the RTP library in active use is still always ortp, but all BTS code now accesses it through the new abstraction layer, paving the way for twrtp option.

[XS] Change in libosmocore[master]: fix --disable-log-macros
by Hoernchen 25 Feb '26

25 Feb '26

Attention is currently required from: Hoernchen, laforge, pespin. Hello Jenkins Builder, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/42203?usp=email to look at the new patch set (#3). The following approvals got outdated and were removed: Verified-1 by Jenkins Builder Change subject: fix --disable-log-macros ...................................................................... fix --disable-log-macros Before 9197c1ac, the AC_ARG_ENABLE(log_macros, ...) action was hardcoded to [log_macros="yes"], so *any* use of the flag --enable-log-macros or --disable-log-macros would set log_macros="yes" -> AC_DEFINE([LIBOSMOCORE_NO_LOGGING]). The commit changed this to the standard [log_macros=$enableval], but broke the conditional test, so - AC_ARG_ENABLE sets $enableval to "no" for --disable-* flags -> log_macros is now "no" -> test fails -> LIBOSMOCORE_NO_LOGGING is never defined... The opposite of what it should do...
