Yes, even though this could/should be improved further.
Currently ffmpeg already tries to use the native aac encoder even if
libfaac is available, but then fails without '-strict -2':
"The encoder 'aac' is experimental but experimental codecs are not
enabled, add '-strict -2' if you want to use it.
Alternatively use the non experimental encoder 'libfaac'."
It would be nice if ffmpeg would automatically choose the best aac
encoder available (libfdk_aac > libfaac > aac > libvo_aacenc), but
does this require anything more than changing the order of
registration in allcodecs.c ?
Now I understand which change you meant above: the aac encoder used for
something like:
ffmpeg -i input.wav output.aac
It seems this uses the first non-experimental encoder and thus could
indeed change e.g. from libfaac to aac. That's not intended.
I had thought about something like:
ffmpeg -i input.mpg -c:a aac output.mpg
That always uses the native encoder, because it's name is just 'aac'.
Trying to be smart in that case and selecting the best available aac
encoder automatically is probably not feasible.
Best regards,
Andreas
