Thanks very much, that solved my problem!

That's good to know! For other people's reference, my new DASH pipeline is:

gst-launch-1.0 souphttpsrc location=$MPD_URL ! dashdemux name=d d. !
video/quicktime ! queue ! qtdemux ! h264parse ! omxh264dec ! glupload !
glcolorconvert ! glcolorscale !
"video/x-raw(memory:GLMemory),width=1280,height=720" ! glimagesink d. !
audio/x-m4a ! queue ! qtdemux ! aacparse ! avdec_aac ! audioconvert !
omxhdmiaudiosink

It gets a bit choppy on the top 720p50 DASH representation when there's
a lot of stuff going on, but I'm guessing this is just in need of some
optimisation.

Cheers,
Sam
