From: Manuel Bachmann Date: Fri, 8 Jul 2016 14:31:01 +0000 (+0200) Subject: Implement JSON configuration file X-Git-Tag: eel_4.99.3~11 X-Git-Url: https://gerrit.automotivelinux.org/gerrit/gitweb?p=staging%2Fagl-audio-plugin.git;a=commitdiff_plain;h=2de141b9a3145a4a8edf2e310adfa8d425637e53 Implement JSON configuration file A JSON configuration file can now be read as "/etc/ pulseaudio-agl.cfg", and a sample one is provided by the package. If it exists and is valid, it will override the default configuration. As a result, the module now depends on json-c.
