The native FFmpeg AAC encoder has been stable since FFmpeg 3.0. If you
|
|
were using libvo-aacenc or libaacplus, both of which have been dropped in
|
|
FFmpeg 3.0, please consider switching to the native encoder (-c:a aac),
|
|
fdk-aac (-c:a libfdk_aac, ffmpeg needs to be installed with the
|
|
--with-fdk-aac option), or faac (-c:a libfaac, ffmpeg needs to be
|
|
installed with the --with-faac option).
|
|
|
|
See the announcement
|
|
https://ffmpeg.org/index.html#removing_external_aac_encoders for details,
|
|
and https://trac.ffmpeg.org/wiki/Encode/AAC on best practices of encoding
|
|
AAC with FFmpeg.
