--- Comment #9 from minfrin at sharp.fm ---
The code that triggers valgrind above does this:

0:10:39.141107388  1574 0x1136d968 DEBUG             transcoder
gsttranscoder.c:783:gst_transcoder_pad_added_cb:<decodebin0> Pad added from
decodebin, caps: video/x-raw(memory:GLMemory), format=(string)RGBA,
width=(int)544, height=(int)576, interlace-mode=(string)mixed,
multiview-mode=(string)mono,
multiview-flags=(GstVideoMultiviewFlagsSet)0:ffffffff:/right-view-first/left-flipped/left-flopped/right-flipped/right-flopped/half-aspect/mixed-mono,
pixel-aspect-ratio=(fraction)64/33, colorimetry=(string)sRGB,
framerate=(fraction)25/1

It appears that the above debug message prints the caps, some part of the caps
having been referenced from the signal created on the following line:

==1574==    by 0x5B36487: gst_rtp_ssrc_demux_class_init (gstrtpssrcdemux.c:385)

Not sure which of this is uninitialised?
