Encoding in AAC HE-AACv2 creates unplayable Audio

[quamt]

Encoding Audio to AAC HE-AACv2 creates unplayable Audio.

syntax:
--audio-codec 1?aac --audio-profile HE-AACv2
Checking with MEdia Info it shows the below:

Audio
ID                                       : 2
Format                                   : mp4a-40-29
Codec ID                                 : mp4a-40-29

Playing the Audio in any player does not work.

Encoding to AAC without any profiles and checking in Media Info

using syntax:
--audio-codec 1?aac
shows:

Audio
ID                                       : 2
Format                                   : AAC LC
Format/Info                              : Advanced Audio Codec Low Complexity
Codec ID                                 : mp4a-40-2

The default libavcodec aac encoder only supports AAC-LC. --audio-profile is meant for other codecs or other aac encoders such as fdk-aac which supports HE-AAC. (fdk-aac cannot be redistributed, so it is not included in my build)

Oh I see, cause its Frauenhofer Codec
How does it look with the implementation of this
https://www.openhub.net/p/fdk-aac would that be possible?

[rigaya]

Building libavcodec with fdk-aac requires --enable-nonfree flag anyway, so it can not be redistributed.

[quamt]

Oh I see.
But it's a bit confusing if it shows in the profiles, you might think it can be used for encoding.

I'll close this issue as the topic has been answered.
