AAC seems to be broken in mpd in trunk

Reported by: anonymous Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version: Trunk
Keywords: Cc:


I have been trying to play aac encoded radio streams with mpd, for example It plays fine for some seconds, but then starts to stutter.
Hardware is an WNDR3700 which I think should have enough power to decode aac.

Also, I have some DRM-free m4a files in my music library which are not indexed by mpd. They don't show up in the log output, so maybe mpd simply ignores the extension.

I investigated a little after seeing that mpd took 100% cpu when playing radio paradise. After a little research I found out that there is a #define in one header file for libfaad2 which disables the use of floating point:
line 68 in common.h : #define FIXED_POINT

Now it plays without stuttering with 10-15% CPU. I think this should be changed in the trunk.

listing of m4a files is still broken though.

I submitted a patch to pass the fixed point argument to make because I tried to edit the common.h manually but couldn't compile. Maybe some "ifdef fixed_point" where commented. Anyway I think the patch is working.
