Hi,
We are using Live555 RTSP code in our application. We have written a
wrapper called RTSPInterface to setup streams and run RTSP server which
runs in a separate thread. The reason we created separate thread
because, other part of the application which does several tasks in
addition to fetching frames to give it to RTSP server via triggerEvent()
approach. We can successfully stream dual streams(HEVC and H.264) using
Live555 RTSP streamer in TCP mode. The application runs continuously for
about 5 and half hours and then crashes with below signature. Could
anyone please suggest me what could be going wrong ? I ran several times
and each time it crashes after about 5 and half hours.
Program terminated with signal 11, Segmentation fault.
