[FFmpeg-user] how to change ffmpeg configuration

[e-letter]

Readers,

An attempt to convert flv to ogg failed:

ffmpeg -i file.flv file.ogg

Stream mapping:

Decoder (codec id 86018) not found for input stream #0.0

Is it correct to conclude that the configuration file needs to be
changed, to enable the aac decoder?

Where is the configuration file to be found?
