Now we add FDK AAC support for both decoding and encoding. It allows adding HE-AAC and HE-AACv2 to your transcoding scenarios. This is also another alternative to ffmpeg decoder for audio streams, while having decent quality.
Let's see how you can set up FDK usage in your scenarios.
First, create a new scenario or modify existing one. If you need to perform only audio transformation, you can add a passthrough for video stream.
|Minimum scenario for audio transformation.|
|Using FDK as decoder.|
If you'd like to encode using libfdk, open encoder dialog and choose libfdk_aac from Encoder drop-down list.
|Using FDK as encoder|
This also allows you to select HE-AAC and HE-AACv2 profiles. Print "profile" in property edit box to get drop-down list of profiles:
Choose aac_he or aac_he_v2 for respective options.
