This is because I couldn't get GStreamer to produce streamable MP4 files
just-in-time yet. For a working AAC transcoder please use 0.15.x or
backport the important details from

The hacks files have nothing to do with transcoding, they contain
work-arounds for several devices, like remapping mime-types, change
device description versions etc.

The -transcoder files are creating instances of the respective class
transcoders (audio/video), sometimes doing a little bit more than that
by altering the resources added to the items.
