Below is the case for Fedora ( and possibly arch ), which use faac encoder.
[rem@fc25 ~]$ gst-inspect-1.0 | grep -i aac faac: faac: AAC audio encoder faad: faad: AAC audio decoder ... [rem@fc25 ~]$ gst-inspect-1.0 faac ... quality : Variable bitrate (VBR) quantizer quality in % flags: readable, writable Integer. Range: 1 - 1000 Default: 100 bitrate : Average Bitrate (ABR) in bits/sec flags: readable, writable Integer. Range: 8000 - 320000 Default: 128000 which supports cbr and vbr, and hence their gstreamer profiles.
