I am getting a crash in the quarktv element however since I am not 100% that my
method is correct I describe it below:

Given a pipeline in PLAYING state:

v4lsrc ! ffmpegcolorspace ! xvimagesink

I block the v4lsrc src pad unlink with the csp. Then I add to the pipeline a
bin containing [ ffmpegcolorspace ! quarktv ] and link the blocked src pad to a
ghost pad on the bin, the bin src pad to the csp and then unblock the blocked
pad.

For most of the *tv filters this always works (i.e. never any crash). With the
quarktv I sometimes get a crash:

Program received signal SIGSEGV, Segmentation fault.
