Problem with encoding in AAc

[kikou2022]

Hi,

I've got an error with my script when I'm try to encoding in AAC.

Here is the problem after a liquidsoap --check :

_**`At airvs-vps.liq, line 478, char 19-143:
output.icecast(%fdkaac(channels=2, samplerate=44100, bitrate=64, afterburner=false, aot="mpeg2_he_aac_v2", transmux="adts", sbr_mode=false),

Error 8: Unsupported format: %fdkaac(channels=2, samplerate=44100, bitrate=64, afterburner=false, aot="mpeg2_he_aac_v2", transmux="adts", sbr_mode=false)`**_

Lot of thanks with your answers !

Hi @kikou2022,
Could you share the information about your setup?

1. Output of liquidsoap --version.
2. Output of liquidsoap --build-config.
3. Installation method.
4. System info, for example lsb_release -a.

Ubuntu 24.04 provides fdkaac without all the high efficiency profiles.
Your problem is similar to #4070, #4261.

[kikou2022]

Thanks @vitoyucepi ! So I understand that the best way is to compile manually fdk-aac ? How can I do that ?

[vitoyucepi]

The best way to run liquidsoap in this case is to use the container image.
If you want to build fdk-aac manually, you should also rebuild all dependencies like ffmpeg and liquidsoap to avoid possible incompatibilities.

Thanks for your help ! I'm going to try that or just continue to use Azuracast ;-)
