SIGSEG while closing VPU decoder

[Bilb]

Hi,

I am not sure this is the correct place for this issue.

When stopping and restarting some times ( > 20times) this pipeline, I get a segfault. I am changing the udport of the source, so I am setting the pipeline to NULL state, update the port and set the pipeline to PLAYING.

The pipeline: udpsrc port=5001 name=udpsrc caps=\"application/x-rtp,pt=96,encoding-name=H264\" ! rtph264depay ! h264parse ! imxvpudec ! appsink name=sink

Here is the backtrace:

Ask me if you need any information.
