 Hi All

 I am relatively new to ffmpeg so i trying to get my head around certain
 things so apologies if this is in the wrong place, but i have been asked
 to setup a service and they require the format of all audio to be in AAC,
 Low Complexity Profile (LC).

 I have been reading through the docs and i can see this command.
 ffmpeg -i input.wav -c:a libfdk_aac -b:a 128k output.m4a

 but i dont have libfdk_aac installed with my ffmpeg system i am a bit
 nervous about messing with my setup as it took me a while to get it all
 installed.

 Here is my ffmpeg setup
 ffmpeg version N-54790-g1816f55-syslint Copyright (c) 2000-2013 the FFmpeg
 developers
   built on Jul 17 2013 21:34:32 with gcc 4.4.7 (GCC) 20120313 (Red Hat

   libavcodec     55. 18.102 / 55. 18.102
   libavformat    55. 12.102 / 55. 12.102
   libavdevice    55.  3.100 / 55.  3.100
   libavfilter     3. 81.101 /  3. 81.101
   libswscale      2.  4.100 /  2.  4.100
   libswresample   0. 17.102 /  0. 17.102
   libpostproc    52.  3.100 / 52.  3.100

 So i am trying to do the task with a different encoder libfaac which is
 installed like this.

 ffmpeg -i BillyGraham_1998.mp3 -c:a libfaac -q:a 330 -cutoff 15000
 output.m4a

 But i get the following errors
 [buffer @ 0x1e12860] Unable to parse option value "0x0" as image size
 [buffer @ 0x1e12860] Unable to parse option value "-1" as pixel format
 [buffer @ 0x1e12860] Unable to parse option value "0x0" as image size
 [buffer @ 0x1e12860] Error setting option video_size to value 0x0.
 [graph 0 input from stream 0:1 @ 0x1e12740] Error applying options to the
 filter.
 Error opening filters!

 Any help would be really appreciated thanks
