About the problem,
I am experiencing segmentation fault crashes while using GStreamer 1.24; the issue also occurs in 1.22 and likely affects other versions as well.
The crash happens when I **repeatedly start and stop an RTSP stream within the same process**.
The first runs work fine, but after several RTSP open/close cycles a **segmentation fault occurs inside `rtpjitterbuffer`**.
This is **not** a fork/exec case; multiple pipelines are **created and torn down multiple times in a single application process**.
Has anyone seen a **segfault in `rtpjitterbuffer` related to repeated pipeline setup and teardown**?
It is difficult to determine the exact condition that triggers the crash.
Are there any **simple tools, debug options, or recommended places to add instrumentation or sanity checks** to help track this down?
Any advice would be appreciated.
**My Pipeline**
`rtspsrc do-rtsp-keep-alive=true location="rtsp://admin:password@172.16.30.1/stream" name="source" nat-method="none" protocols="udp" teardown-timeout="500000000" ! rtph265depay ! h265parse config-interval=1 ! tee name=t t. ! queue max-size-buffers=1 max-size-bytes=0 max-size-time=0 ! rtph265pay config-interval=1 ! application/x-rtp,media=video,encoding-name=H265,payload=96 ! queue max-size-buffers=1 max-size-bytes=0 max-size-time=0 ! webrtcbin bundle-policy=max-bundle name=webrtc t. ! appsink drop="true" emit_signals="true" max-buffers="1" name="sei_sink" sync="false"`
