My guide for compiling PJSIP on the Raspberry Pi 3 with audio and video support
Howdy. Here is my writeup for compiling the PJSIP stable release on the
Raspberry Pi 3 / Raspian Stretch with the Raspberry Pi Camera module,
allowing audio and video sip calls:
I only have one issue at the moment. When hanging up from a video call, I
get a segmentation fault on the pjsua application when the SDL video stream
is closed:
16:29:24.742 pjsua_media.c ......Call 2: deinitializing media..
16:29:24.757 pjsua_media.c ........Media stream call02:0 is destroyed
16:29:24.757 pjsua_vid.c ........Stopping video stream..
16:29:24.776 v4l2_dev.c .........Stopping v4l2 video stream mmal
service 16.1
16:29:25.835 pjsua_vid.c .........Window 1: destroying..

16:29:25.835 v4l2_dev.c ..........Destroying v4l2 video stream mmal

16:29:25.837 sdl_dev.c ..........Stopping sdl video stream

Segmentation fault
If anyone has a solution or I find one independently, I will update the
guide.

Hello Adam,
thank you very much for the guide! In fact I had already compiled PJSIP on the RPI 3 before and also faced the SSE2 problem that you mentioned in your writeup. I fixed the issue in a way similar to yours. However this is a bug that should ideally be fixed in PJSIP itself. It also made it a bit hard for me to get started with PJSIP...
I also have an issue with a segmentation fault at the end of the call and am currently investigating where it comes from. Fortunately I am a professional C++ software developer and I hope that my C++ debugging skills help me to find the root cause of the issue. From what you are telling me, your problem looks like a similar issue. You might want to run the PJSUA application from inside GDB, then you will also see a backtrace of the segmentation fault, which will be helpful to debug the issue.
I will keep you up to date with my progress on the segmentation fault. I think that this is a coding bug in PJSIP.
Kind regards,
Christian
