           Summary: Crash when continuously resizing a video pipeline
                    after some time

Reproducer of the bug

When I continuously resize a running pipeline which decodes an H264 stream from
the network, the pipline crashes after some time below libgstvaapi.so. If I
don't use vaapi elements, the pipeline doesn't crash.
I've written a reproducer which generate an H264 stream with the following
pipeline:
gst-launch-1.0 videotestsrc ! video/x-raw,width=1920,height=1080 ! vaapih264enc
! h264parse config-interval=2 ! rtph264pay ! udpsink
The program opens an X11 window which displays the video and always resizes it.
After some time the program crashes.
The decoding pipeline which is used looks like:
udpsrc ! application/x-rtp,encoding-name=H264 ! rtph264depay ! decodebin !
vaapipostproc ! capsfilter ! appsink
The resizing is done by inserting a probe at the source pad of decodebin and in
the callback width and height of the capsfilter and vaapipostproc are changed.

Regards,
Thomas
