Memory leak in capsfilter application/x-rtp

[Saurabh Bora]

Hi Experts,

I have a gstreamer test pipeline which I run as below:
gst-launch-1.0 videotestsrc is-live=yes ! aspectratiocrop aspect-ratio=4/3
! vp8enc ! rtpvp8pay !
application/x-rtp,media=video,encoding-name=VP8,payload=96 ! rtpvp8depay !
decodebin ! autovideosink

Also, I have following environment variables set to generate leak trace:
set GST_DEBUG=GST_TRACER:7
set GST_TRACERS=leaks
set GST_DEBUG_FILE=logTrace

Below is content of logTrace file, which shows leak in capsfilter -
application/x-rtp,media=video,encoding-name=VP8,payload=96. As all the
elements in the pipeline are gstreamer provided and not custom, I do not
understand how I can fix this. Please help and guide.

P.S.- The above pipeline is a test pipeline used to demonstrate leak. My
original pipeline uses the same capsfilter and hence I need to fix this
leak.

Help Appreciated !
