How to use FFmpeg libfdk_aac with HE-AACv2 audio?

[Hankuuuu]

May I ask, the "libfdk_aac" supports the latest "HE-AACv2", which has excellent audio quality, even twice as good as "LC-AAC".

However, in the software, the default "libfdk_aac" converts to the "LC-AAC" version. How can I configure it to use "HE-AACv2"?
I tried adding various "imagined possible parameters" to the "Fastflix.yaml" but had no luck. Does anyone know how to do it?

On the Quality tab, down at the bottom try the custom ffmpeg option -profile:a aac_he_v2 (If you have more than one audio track, look at the raw command and use the number instead, like -profile:1

I don't have a ffmpeg with libfdk handy, so hope this works!

You are amazing. It works. Thank you!

I downloaded the FFMpeg with libfdk_aac from Martin:
https://github.com/MartinEesmaa/VVCEasy/releases
「Windows_FF_VVCEasy.7z」

Martin created an extremely powerful H266 FFMpeg,
and his homepage mentions that your software is the top choice for H266.

Glad it worked! I am working on better audio conversion page for the next version, as dream is version after that could add profiles or custom audio options directly from audio conversion popup. Will keep this open as a reminder :)
