#9574 new defect
-profile option only accepts numeric values for aac_at encoder

Description
The definition of
static const AVOption options[] = {
misses the line
FF_AAC_PROFILE_OPTS
so profile names cannot be mapped to numbers. When specified as numeric values, the profiles work just fine, e.g. 4 works as aac_he and 28 as aac_he_v2

To be specify, this is not using the ffmpeg command line executable, but rather the libavcodec/libav directly.
I compile it for conda-forge https://github.com/conda-forge/ffmpeg-feedstock so it isn't too hard to go to historical versions.
Unfortunately, I use PyAv https://github.com/PyAV-Org/PyAV/ shims for compatibility, so it isn't super easy for me to give you code in C to reproduce.

works but reveals that the error that I'm getting through the C-API might be due to a missing lookup????
And sorry, i just noticed that the issue was opened 3 years ago.... i thought I read "3 days ago"...

I've noticed the same thing for the h264 encoders (h264_nvenc, hevc_nvenc, libopenh264).
One thing I've noticed is that:
If I try to specify profile 77 (as a string) it finds the MAIN profile for all 3 on version 7.1.0 it works.
On Version 6.1.2 and 7.0.2 profile 77 (as a string) gives: Numerical result out of range with h264_nvenc.
I'm currently switching on the version of FFMPEG to get around it.
