<p>I am attempting to add secondary audio with FFmpeg to copy my primary audio over and encode it with libfdk_aac using profile aac_he. When I do, I am getting the following errors:</p>

(Asked by: username_0 on 2024-01-25)

I am attempting to add secondary audio with FFmpeg to copy my primary audio over and encode it with libfdk\_aac using profile aac\_he. When I do, I am getting the following errors:

[NULL @ 000001f4d7830b80] [Eval @ 0000003fb93fdf50] Undefined constant or missing '(' in 'aac\_he'
[NULL @ 000001f4d7830b80] Unable to parse option value "aac\_he"
[NULL @ 000001f4d7830b80] Error setting option profile to value aac\_he.
Error setting up codec context options.
Error initializing output stream 0:1 --\*
Here is the command I am trying to use:

ffmpeg -y -fflags -genpts -i -map 0:v -c:v copy -map 0:a -c:a:0 copy -map 0:a -c:a:1 libfdk\_aac -profile:a aac\_he e:\nf.ts
I would expect it to copy the Primary audio to Audio 1 (AC3), and then re-encode the audio from Audio 1 to to Audio 2 (aac\_he).

If I only use aac native audio, instead of aac\_he, it works fine using this command:

ffmpeg -y -fflags -genpts -i %%f -map 0:v -c:v copy -map 0:a -c:a:0 copy -map 0:a -c:a:1 aac e:\nf.ts
From this, I get Audio 1 (AC3) and Audio 2(aac).

or it works if I just re-encode the primary audio like using this command:

ffmpeg -y -fflags -genpts -i %%f -map 0:v -c:v copy -map 0:a -c:a:0 libfdk\_aac -profile:a aac\_he e:\nf.ts
From this, I get Audio 1(aac\_he)

Is there something about using the aac\_he in the secondary audio position that ffmpeg has issues with?

`-profile:a aac_he` applies to *all* output audio streams. Apply it to only the intended stream; `-profile:a:1 aac_he`.
