PJSUA running on Raspberry Pi 3 hit Segmentation fault when stopping video stream.
Hello PJSIP developers/users,
I've been building PJSIP 2.7.1 on Raspberry Pi 3 Model B with OS Raspbian
Stretch Lite. Video is needed so V4L2, SDL2, and OpenH264 are all built and
installed. When I ran PJSUA on RPi calling another softphone with video
enabled, everything went well, both audio and video were working. Every
time when hangup it gave Segmentation fault though.
The RPi was used without a UI, I was ssh-ing to it for all the builds/runs.
Camera is a Raspberry Pi Camera Module v2.
Here is a snippet of info from "gdb" when stopping the video call and the
segfault came up. I also tried sample "vid_streamuntil" and it gave
segfault as well when quitting. The same setup on Raspian Jessie Lite gave
no difference.
Anyone have a clue what the problem could be? Could it be something with
SDL, since segfault happened when stopping the SDL video stream? Struggling
with this for days, any comments are appreciated.
