SourceSecondPath and "Got signal 11 (Segmentation fault), crashing"

[zmaximz]

Hello, I try to test SourceSecondPath and getting error with ffmpeg
At Source Path I have:
rtsp://user:password@xxx.xxx.xxx.xxx:554/user=user_password=password_channel=1_stream=0.sdp?real_stream
And it's working ok, but when I try to add SourceSecondPath:
rtsp://user:password@xxx.xxx.xxx.xxx:554/user=user_password=password_channel=1_stream=1.sdp?real_stream
I've got error:

This error happens with 1.36 mariadb (recently updated from 1.34) and 1.37 mysql (got from docker hub), I try different settings of camera, seems it's not camera fault, any ideas whats wrong please?

Why have you added the second source?

[zmaximz]

Why have you added the second source?

Low res can be used for motion detection in 1.37 with more efficient CPU usage (I guess in 1.36 too)

Got some ffmeg logs, not really understand whats going on but this maybe will be in help

Set up the low resolution stream as a separate monitor.

[zmaximz]

Set up the low resolution stream as a separate monitor.

It was already in that way, but if I have 20 cams it's annoying to have 40 monitors and to edit their settings for example, I think this function must work


Other way is to use zmtrigger, but I dont understand it well... it mast to select monitor by ip of camera and some message to socket from it.
I'll use maybe python and api... is it a good way to trigger alarm through api?

[Magic919]

SourceSecondPath doesn't do what you think it does.

I haven't used external triggers.

[zmaximz]

SourceSecondPath doesn't do what you think it does.

Heh? But in 1.37 if you define SourceSecondPath and save, there will be option to select Secondary Stream in Analysis, I can't find more info about it

Other option, there are onvif motion trigger, but I have error with onvif, I'm using this docker image https://hub.docker.com/r/bkjaya1952/zon ... ker-latest and don't understand. There must be some sort of specific compilation or release of zoneminder to support onvif? (I've send some onvif post request to camera with postman and they working)

Code: Select all

2022-04-14 14:12:49	zmc_m1		370	ERR	zmc not compiled with GSOAP. ONVIF support not built in!	zm_monitor.cpp	980
2022-04-14 14:12:49	zmc_m1		370	INF	Starting Capture version 1.37.13

I will build zoneminder from source next time, don't understand, at source all that proxy wsdl already exist

At this point I can write alarm server that will trigger event with zmtrigger, but searching more elegant way...

Anyway 1.37 looks super promising, great cpu improvement, especially with decoding on demand and janus, about 60 cams 4fps with motion detection decreased cpu usage from 60% to 10%

The multistream feature isn't implemented yet. SecondStream can only be used for an audio stream.
