+ <h3 id="removing_external_aac_encoders">January 30, 2016, Removing support for two external AAC encoders</h3>
+ We have just removed support for VisualOn AAC encoder (libvo-aacenc) and
+ libaacplus in FFmpeg master.
+ Even before marking our internal AAC encoder as
+ <a href="#aac_encoder_stable">stable</a>, it was known that libvo-aacenc
+ was of an inferior quality compared to our native one for most samples.
+ However, the VisualOn encoder was used extensively by the Android Open
+ Source Project, and we would like to have a tested-and-true stable option
+ in our code base.
+ When first committed, libaacplus filled in the gap of encoding High
+ Efficiency AAC formats (HE-AAC and HE-AACv2), which was not supported by
+ any of the encoders in FFmpeg at that time.
+ The circumstances for both have changed. After the work spearheaded by
+ Rostislav Pehlivanov and Claudio Freire, the now-stable FFmpeg native AAC
+ encoder is ready to compete with much more mature encoders. The Fraunhofer
+ FDK AAC Codec Library for Android was added in 2012 as the fourth
+ supported external AAC encoder, and the one with the best quality and the
+ most features supported, including HE-AAC and HE-AACv2.
+ Therefore, we have decided that it is time to remove libvo-aacenc and
+ libaacplus. If you are currently using libvo-aacenc, prepare to transition
+ to the native encoder (<code>aac</code>) when updating to the next version
+ of FFmpeg. In most cases it is as simple as merely swapping the encoder
+ name. If you are currently using libaacplus, start using FDK AAC
+ (<code>libfdk_aac</code>) with an appropriate <code>profile</code> option
+ to select the exact AAC profile that fit your needs. In both cases, you
+ will enjoy an audible quality improvement and as well as fewer licensing
