I tried running the new shmsrc bin from
https://github.com/vliaskov/libremapping (branch: feature/shmsrcbin-rebase-oct2014)

In order to perform the test I first run:
$ gst-launch-1.0 uridecodebin uri=file:///home/tats/Documents/workspace/mapmap/DESTRUCT.mov ! queue ! videoconvert ! video/x-raw, format="RGBA" ! gdppay ! shmsink socket-path=/tmp/sock shm-size=100000000
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Redistribute latency...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock

Then I run mapmap and try to add a new media file at /tmp/sock:

$ ./mapmap
Using GStreamer version 1 . 2 . 4
Video support: yes
Listening osc.udp://localhost:915912800
Could not add OSC handler Opening movie: "/tmp/sock" .
URI for uridecodebin: /tmp/sock
Pipeline started.
Pipeline state for movie changed from NULL to READY:

@vliaskov
Fix some issues with shmsrc pipeline and video dimensions (bug #29)
835165c 
Shmsrc seems to work with a gstreamer 1.4 build, but not with distro gstreamer
(segfault due to missing fix https://bugzilla.gnome.org/show_bug.cgi?id=731093)
Reader / writer of live source need to be using same gstreamer build, otherwise
some pipeline problems appear in deserializing and caps detection.

Playback of the first shape mapped with the live source doesn't seem to work (?),
so this bug stiil needs investigation.

Try with current develop and a recent build of gstreamer, gst-plugins-{base, good, bad), gst-libav (e.g. 1.4 version from all repos). I fixed some issues in following commit:
835165c

it still needs some work though
