Note the use here of the MP4 mux and AAC audio. “libfdk_aac” signals
-te use of Franhofer's `FDK-AAC <https://github.com/mstorsjo/fdk-aac>`_ encoder
+the use of Franhofer's `FDK-AAC <https://github.com/mstorsjo/fdk-aac>`_ encoder
from Android; it yields significantly better sound quality than e.g. FAAC,
and it is open source, but under a somewhat cumbersome license. For this
reason, most distributions do not compile FFmpeg with the FDK-AAC codec,
so you will need to compile FFmpeg yourself, or use a worse codec.
+FFmpeg `recommends <https://trac.ffmpeg.org/wiki/Encode/HighQualityAudio>`_
+their own native AAC encoder (simply called “aac”) in the absence of any
+external libraries.
For speed control, you can use::
TCP retransmits. See the cubemap documentation for more information about
how to set up pacing.
+For transcoded Cubemap output from VLC you can take exactly the same line as
+earlier, just adding “metacube” to the HTTP options::
