Cool stuff! Great to see you have finally decided to upstream this.

This doesn't sound very appealing to me.

I would strongly prefer a setup where the DASH plugin comes into play only when
a DASH manifest file is detected. This means there either needs to be a special
URI scheme (not a great approach), or a manifest file "demuxer" approach  a la
hlsdemux needs to be taken. "demuxer" is a bit misleading here, since it's not
really doing any demuxing at all, it's just how it appears to playbin2 really
and where it sits in the autoplugging order. Once it gets the initial
playlist/file, it takes over.

I haven't looked at the DASH code yet and my memory of DASH is a bit hazy, but
from what I remember I would think that it should be possible to adapt the
existing hls-targetted base class to accommodate DASH as well.
