Coverting Audio to AAC using ffmpeg

[Sam]

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 4.4.7-3)

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

This is a bug tracker, not a support forum. Please post all usage questions to the ffmpeg-user user mailing list.
Note that it is not necessary to install FFmpeg to run it (I never install).
