Hello When I try to play an internet radio stream in aac format with MOC I get the error message "Format not supported". MOC should be able to handle aac streams, this user reports that it works for him: http://crunchbang.org/forums/viewtopic.php?pid=424012#p424012 I've also tested playing some aac-audio local files, no problem - worked fine. Downloaded from here: http://download.wavetlan.com/SVV/Media/HTTP/http-aac.htm The audio streams which I've encountered the error for are SomaFM:s radio channels, for example this: https://somafm.com/silent/ https://somafm.com/silent130.pls I asked around a bit on the #fedora irc-channel about this and some thought that the build/packaging of moc looked a bit fishy. The file /usr/lib64/moc/decoder_plugins/libaac_decoder.so is currently missing, is that correct? I think that another potential issue was that faad2 (unsure about exact name) was missing from the spec file. Unfortunately I cannot provide you exact information since I don't really know a lot about the rpm-system. Any thoughts on this? Playing local files went well but there's some problem with streams... --- System info Fedora 23 x86_64 dnf repolist Last metadata expiration check: 1 day, 6:11:54 ago on Sat May 14 11:00:27 2016. repo id repo name status adobe-linux-x86_64 Adobe Systems Incorporated 2 *fedora Fedora 23 - x86_64 46,074 rpmfusion-free RPM Fusion for Fedora 23 - Free 692 rpmfusion-free-updates-testing RPM Fusion for Fedora 23 - Free - Test Updates 268 rpmfusion-nonfree RPM Fusion for Fedora 23 - Nonfree 206 rpmfusion-nonfree-updates-testing RPM Fusion for Fedora 23 - Nonfree - Test Updates 103 *updates Fedora 23 - x86_64 - Updates 18,818 mocp --version This is : Music On Console Version : 2.6-alpha1 Built : Nov 6 2015 11:00:12 Compiled with : OSS ALSA JACK Network streams resample Running on : Linux 4.4.9-300.fc23.x86_64 x86_64 Author : Damian Pietras Homepage : http://moc.daper.net/ E-Mail : mocmaint(a)daper.net Copyright : (C) 2003-2014 Damian Pietras and others License : GNU General Public License, version 2 or later
