Q. Huh! Why is MPPENCODER (with MPP) and .mpc the extension?
A. Dunno. You must ask the guys who created and defined the format. The
standard is MPEGplus (MPP/MP+) but the files use .mpc extension.

+Q. Why do I get .aac files instead of .m4a files when I encode with faac?
+A. Faac uses mp4v2 to create aac files in an m4a or mp4 container. Some
+ Linux distros have disabled this mp4v2 support due to a licensing issue
+ and this leave faac only capable of generating mpeg-2/ADTS streams.
+ These streams should correctly have the .aac file extension and some
+ players (such as Audacious) will not even play mpeg-2/ADTS streams when
+ they are placed in an .m4a container.
+ As of version 2.6.1 abcde tests the version of faac being used for mp4v2
+ support and then appropriately places the audio either in .m4a or .aac.
+ Note that tagging is not possible with mpeg-2/ADTS streams in .aac.
