From dba13d03bc8e827fededc20b0ab1f574a1500f2a Mon Sep 17 00:00:00 2001 From: Philip-Dylan Gleonec Date: Thu, 11 Feb 2021 12:25:14 +0100 Subject: [PATCH 2/2] avcodec/libopusenc: reload packet loss at encode An estimation of packet loss is required by libopus to compute its FEC data. Currently, this estimation is constant, and can not be changed after configuration. This means an application using libopus through ffmpeg can not adapt the packet loss estimation when the network quality degrades. This patch makes the encoder reload the packet_loss AVOption before encoding samples, if fec is enabled. This way an application can modify the packet loss estimation by changing the AVOption. Typical use-case is a RTP stream, where packet loss can be estimated from RTCP packets.

2022-08-09build-system: Add 'channel-build-system'....* gnu/ci.scm (channel-build-system, channel-source->package): Remove. * gnu/packages/package-management.scm (channel-source->package): New procedure, moved from (gnu ci). * guix/build-system/channel.scm: New file, with code moved from (gnu ci). * doc/guix.texi (Build Systems): Document it. Ludovic Courtès
2022-07-10monads: Add 'mparameterize'....* etc/system-tests.scm (mparameterize): Move to... * guix/monads.scm (mparameterize): ... here. * tests/monads.scm ("mparameterize"): New test. * .dir-locals.el (c-mode): Add it. Ludovic Courtès
2022-04-11tests: System tests really parameterize 'current-guix-package'....Until now, 'current-guix-package' was parameterized in the wrong context. Thus, 'current-guix' would end up building a variant of the 'guix' package instead of the package returned by 'channel-source->package', which is much less expensive to build. * etc/system-tests.scm (mparameterize): New macro. (tests-for-current-guix): Change the 'value' field of each <system-test> record to parameterize 'current-guix-package' for good. Ludovic Courtès
2020-03-23tests: Use the same source as ci.guix.gnu.org....* etc/system-tests.scm (system-test-manifest): In 'local-file' call, use a name that is a function of COMMIT to match what Cuirass does. Ludovic Courtès
2020-03-05tests: Add a manifest for system tests....The manifest can be passed to 'guix build -m', 'guix weather -m', and so on. It can also be passed to an installed 'guix' (without ./pre-inst-env), with the exception so far of installation tests. * build-aux/run-system-tests.scm: Remove. Move interesting bits move to... * etc/system-tests.scm: ... here. New file. * Makefile.am (EXTRA_DIST): Remove 'build-aux/run-system-tests.scm' and add 'etc/system-tests.scm'. (check-system): Rewrite to run 'guix build -m etc/system-tests.scm'. Ludovic Courtès
