--- Comment #1 from Tim-Philipp Müller <t.i.m at zen.co.uk> ---
Thanks for the bug report. Please bear with us while we're trying to wrap our
head around that. I'm not sure if I properly understand the issue yet.

If you run two instances of gst-launch-1.0 like this:

  gst-launch-1.0 videotestsrc is-live=true ! queue ! progressreport !
rndbuffersize ! queue ! filesink location=/tmp/1.out

  gst-launch-1.0 videotestsrc is-live=true ! queue ! progressreport !
rndbuffersize ! queue ! filesink location=/tmp/2.out

Does this work fine?

Does the multiprocess.Process() interface effectively call fork() ? I don't
think you can really do that safely with GStreamer/GLib applications after
gst_init().
