hi, I have specific questions to ask on how zone minder does play/pause/fwd/next on event streams in the web interface. Is this the right place to ask?

Well, I usually start with event.php view, look for the button I am interested in, and see what function it calls: https://github.com/ZoneMinder/ZoneMinder/blob/m...

Looks the buttons are defined in a block called dvrControls at line 161

thanks yes, I have been looking at it. I am actually using img src="/cgi-bin/nph-zms?source=event&mode=jpeg&event=1744&frame=1&scale=100&rate=100&maxfps=5&replay=single&user=xxx&pwd=xxx" to plan and event Id (which I get from the API) and it plays the event great

now,

from what I gather, “server.com:port/?view=request&request=stream&connkey={connKey}&cmd=X” is what it is using to send commands where X = 1,2,3,4 for various functions

I'm trying to understand where connKey comes from

if its being returned in an HTTP header in the image load, then I will need to issue an HTTP command myself instead of the convenient img src

so I was wondering if there is an easier way to send commands to the current stream that is playing

Looks like that is done with generateConnKey() in functions.php: https://github.com/ZoneMinder/ZoneMinder/blob/m...

.....and its jsut a random number.....

and that confused me -- if that is the case, how is the command to stop/play relating to that specific stream?

I tried to do a CURL POST ?view=request(etc) with command=3 (STOP) while a stream was playing and it did not stop, which is not surprising as it can't correlate

oh

let me check something - I'm trying to trace what web console does with httpry

curl -X POST http://server.com/zm/index.php?view=request&...

is what should be moving to the next event if I look at /skins/classic/views/js/event.js

but it ain't. Need to dig more

I bet there is some context stuff - for example, if 3 people log into the admin, and one person does a "next" only his stream should go to next not all (is my guess)

you need the connkey

it is part of the streamPArms: https://github.com/ZoneMinder/ZoneMinder/blob/b...

argh

I was using the wrong POST format in cURL - its gotta be -d "?view=request<etc>"

and you are right

I do need the connkey

at least now I'm getting the right error back

oooh yeah

thusly works

now I need to figure out how to generate that connkey correctly in my app --> inside img src -- I'll figure that out tomorrow

thanks knnniggett

whoop - its as simple as generating a connKey and adding it to the img src url
