I have tried to manually build the pipeline as similar to the one playbin2
creates. It goes like this:

/usr/local/bin/gst-launch-0.10 -v filesrc location=/home/storage/bbc-end2.ts !
typefind ! mpegtsdemux name=demux multiqueue max-size-buffers=0
max-size-time=2000000000 max-size-bytes=2097152 use-buffering=true name=mq
demux. ! mq.sink0 mq.src0 ! mpegaudioparse ! mad ! input-selector ! tee ! queue
! audioconvert ! audioresample ! alsasink demux. ! mq.sink1 mq.src1 ! mpeg2dec
! input-selector ! queue ! videoscale ! xvimagesink

Only difference I can see is that there is no way to insert that
GstStreamSynchronizer element, but otherwise pipelines are pretty close.

Crucial thing is playbin2 hangs while the manual pipeline does not.

Can someone please look at the pipelines and see if I got it right?

If I have, what could be causing the hang? I see that streamsynchronizer is
made running in pass-through mode by default - but would it make sense to
actually attempt to remove it from the playbin2 pipeline to see what happens?
