AAC cannot go below 32

[TheJ]

So as of recently i have been messing around with FFmpeg and i noticed with their AAC encoder can go below 32k, which really surprised me since i dont know that was possible. So i checked in hybrid to my surprise you cant, even though after turning on the FDK option, why?

Because there is no point for a video re-encoder like Hybrid?

AAC starts sucking with lower bitrates so they invented AAC-HE(+/v1/v2) for DAB+ radios /car head units to limit data as much as possible. As can be seen in qaac's Shittime wrapper specs the <32k bitrates are only for reduced sample rates (designed for talkback radio mostly).

For extra ridiculousness: none of my 4 DAB+ radio/head units can playback AAC audio in a file.

The rest of the non-proprietary format world moved to using Opus.

"AAC starts sucking with lower bitrates"
which is exactly the point, to fit 8mb videos on Discord
