AAC decoding no longer works in mplayer-bin-1.0_rc1-r3. It worked before in 1.0_pre8, but the new emul-linux-x86 libraries has made downgrading impossible (pre8 is now blocked). ... Requested audio codec family [faad] (afm=faad) not available. Enable it at compilation. Cannot find codec for audio format 0x20434141. Read DOCS/HTML/en/codecs.html! ... FAAD can be enabled simply by toggling the "aac" USE flag at build time, yet it seems to have been disabled in the 1.0_rc1-r3 build. What is the problem? Reproducible: Always
Apparently emul-linux-x86-medialibs does not include FAAD libraries, so mplayer-bin does not have AAC support. http://forums.gentoo.org/viewtopic-p-3956547.html#3956547 So it would seem that medialibs will have to be updated before this issue can be resolved.
