ffmpeg's internal AAC encoder should be preferred over libvo_aacenc due to its much better quality. The experimental label is there for historic reasons -- there is nothing unstable about it. Changed "-2" to "experimental" argument, because easier to remember. Added libfdk-aac as it's preferred over libvo_aacenc for quality reasons. Added meaningful command line examples.

FFmpeg has been built without libfaac for licensing reasons;
|
|
libvo-aacenc is used by default.
|
|
To install with libfaac, you can:
|
|
brew reinstall ffmpeg --with-faac
|
|
|
|
You can also use the experimental FFmpeg encoder, libfdk-aac, or
|
|
libvo_aacenc to encode AAC audio:
|
|
ffmpeg -i input.wav -c:a aac -strict experimental output.m4a
|
|
Or:
|
|
brew reinstall ffmpeg --with-fdk-aac
|
|
ffmpeg -i input.wav -c:a libfdk_aac output.m4a
