In version 1.2.0 the built-in AAC encoder of FFMpeg seems to be broken. I will look into this, yes.
But there is an alternative / workaround:
- Simply extract the libfdk-aac-2.dll file from the attached zip archive to your C:\windows\system32\ directory.
You will then have the Fraunhofer AAC encoder available in Voukoder. This will work - maybe even better.
For licensing reasons both needs to be separated.
