[solved] Hikvision DS-KB8112-IM connection to ZM?

[DonZalmrol]

Its a virtual headless server, so I will not be able to display an output.
But I will try this tonight, perhaps it display some more information about the stream.

On my computer it open without any issues besides the previous mentioned error messages.

[Magic919]

Mine's an AM, but otherwise similar. It's more about reading the text when it fails.

[iconnor]

Some cameras don't do tcp. Try udp.

[DonZalmrol]

When I run it from my server I get this message:

Code: Select all

Don't think its due to TCP vs UDP, tried changing the setting before and it didn't do much else...

[Magic919]

Sounds like you need to put the RTSP part in quotes.

[DonZalmrol]

Ok, stupid of me. It was indeed the quotes.
Now I get a different error with ffplay:

Code: Select all

Could not initialize SDL - No available video device
(Did you set the DISPLAY variable?)

But that could be due to the fact its a headless server (no physical monitor, its a virtual machine).

After testing yesterday I've build a new server and set it up.
Same issue persists. I'm starting to believe that these door stations from HikVision don't use the proper RTSP stream settings/ protocol.

Now my Zoneminder is giving me this error

Code: Select all

Unable to open input rtsp://username:password@ipaddress:554/h264/ch1/main/av_stream due to: Invalid data found when processing input

Same error occurs when you run the command on the server via ssh directly.

[Magic919]

Ok.

I just run one of the other ff progs, such as ffprobe -i rather than ffplay (for the exact reasons you stated). ffmpeg -i works and of course stops with the error showing no output specified.

What this all suggests is it's an ffmpeg error that is just surfacing via ZM.

I'd go with running ffprobe, add a '-report' argument and then it'll create a file in the directory you run it from named ffprobe-DATE-TIME.log. Have a look for signs of trouble in there.

[DonZalmrol]

Ha when running the ffprobe I now get this error:

Code: Select all

[rtsp @ xxx] method OPTIONS failed: 401 Unauthorized
rtsp://username:password@ipaddress:554/h264/ch1/main/av_stream: Server returned 401 Unauthorized (authorization failed)

The virtual server is in the same vlan as the camera's so you couldn't say its being blocked by my firewall.
Also if it would be blocked by the firewall the other cams shouldn't work neither since these also use RTSP...

EDIT:

The FFProbe did returned a log:

So it connects to the door station, but then fails when it gets to the OPTIONS part.

[DonZalmrol]

Found the issue!!!

It was due to the password I've used, seems that the encoding messes up passwords with special characters...
Example from someone else who had it: https://stackoverflow.com/questions/589 ... ing-opencv

[iconnor]

So I'm wondering if we should be translating %'s into %25's when passing the url to ffmpeg..

Kinda annoying

[Magic919]

Good to see you've made progress with it.

[DonZalmrol]

Well I had a different character then the '%' sign.
Suffice to say certain characters will/ could break the URL.

e.g. '@', '%', ...

Not sure if these are "fixable". Anyway its resolved

[Magic919]

Good. Means I can safely add the doorbell to my Xmas list.
