[FFmpeg-user] AAC, Low Complexity Profile (LC).

[sobytes]

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

libavutil 52. 40.100 / 52. 40.100
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
