Describe the issue/problem and steps to reproduce

Motionplus crashes when I'm trying to get JSON object with information about all movies:

/ # curl -v localhost:8080/0/movies.json
* processing: localhost:8080/0/movies.json
*   Trying [::1]:8080...
* Immediate connect fail for ::1: Address not available
*   Trying 127.0.0.1:8080...
* Connected to localhost (127.0.0.1) port 8080
> GET /0/movies.json HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/8.2.1
> Accept: */*
>
* Empty reply from server
* Closing connection
curl: (52) Empty reply from server

After that it just crashes. Below are logs from host server (motionplus runs inside docker container):

Yep. Individual cameras work. Using a 0 for camid causes crash. Tested on ubuntu 20.04 wsl env.

Not related to this issues, just found out that motionplus uses much more CPU than motion.

This is with 4 network IP camera with RTSP, on home server with Celeron J4125 2.00GHz.

I don't think source builds are inheriting CFLAGS (into CXXFLAGS) at the moment.

Weirdly, it's something I noticed earlier today myself and was going to put in a bug report on once I'd tracked down the cause.

You can tack '-g -O2' onto the end of CXXFLAGS in motionplus/src/Makefile as a work around though.

Hi @jimtuck. There is no such file motionplus/src/Makefile. I found (by grep-ing) CXXFLAGS in motionplus/configure.ac only.

Is it right place?

$ grep -R CXXFLAGS .
./configure.ac:CXXFLAGS="$CXXFLAGS -std=c++17"

The makefiles only exist after you've run 'autoreconf -fiv' and './configure', but you can add '-g -O2' to configure.ac before running them and they'll be included in the makefiles.
