Hi Thomas,

detecting libilbc fails with

ffconf.DC5UxjIt.c:(.text.startup+0x1b): undefined reference to 
`WebRtcIlbcfix_InitDecode'

This function is not part of our libilbc version.

Detecting libcdio fails with

/tmp/ffconf.bwyXkIcF.c:1:32: fatal error: cdio/paranoia/cdda.h: No such 
file or directory
 #include <cdio/paranoia/cdda.h>

According to https://ffmpeg.org/pipermail/ffmpeg-cvslog/2013-
January/059617.html we need a seperate cdparanoia package because the 
headers needed by ffmpeg were split from libcdio. According to https://
bugs.busybox.net/show_bug.cgi?id=7826 there is no cdparanoia package in 
buildroot.

Regards, Bernd
