OK there's a bunch of interesting things in this log, first thing I notice is :

0:00:00.148947972  3618  0x8b17430 DEBUG          adaptivedemux
gstadaptivedemux.c:653:gst_adaptive_demux_expose_stream:<dashdemux0> Adding
srcpad '':video_00 with caps audio/x-m4a

which is a bit confusing :)

I also notice this :

0:00:01.793368579  [...]Last 3 fragments average bitrate is 898837
0:00:01.793655216  [...] mediaURL = V2.mp4/3
0:00:01.793727944  [...]Downloading uri:
http://rdmedia.bbc.co.uk/dash/ondemand/bbb/avc3/1/V5.mp4/IS, range:0 - -1

This shows that the patch correctly calculates the bitrate, and the subclass
selects an appropriate representation, but I'm not sure why the V5
representation is downloaded anyway.

I'll look into these issues, but it would still be helpful to know how you
limit the bandwidth on your end so I can reproduce Alex ?
