mfaacenc

This element encodes raw audio into AAC compressed data.

Example pipelines

 gst-launch-1.0 -v audiotestsrc ! mfaacenc ! aacparse ! qtmux ! filesink location=audiotestsrc.mp4

This example pipeline will encode a test audio source to AAC using Media Foundation encoder, and muxes it in a mp4 container.
