onvif | ONVIF node.js implementation | Video Utils library

I want to get a video with start time and end time from RTSP server. From Maxim-zapryanov's answer at the discussion, I know to do it, I need set time range at PLAY packet's "range" header field

To play from a specific time you need to use the RTSP header field "range" for the PLAY command. See section 6.5.1 of https://www.onvif.org/specs/stream/ONVIF-Streaming-Spec.pdf and https://datatracker.ietf.org/doc/html/rfc2326#section-12.29

I used Live555 lib to set the field to PLAY packet success. But I want set the field by FFmpeg lib instead of Live555 lib.

So, does FFmpeg lib support set time range at PLAY packet's "range" header field when get video from RTSP? If yes, how to do it?

If anyone know the answer, please tell me know. Thank you so much!

I'm trying to set the point called "Preset001" with a well-defined Speed but I can't as I get the following error on console:

like the title says, I am wondering if for example I send an endpoint some XML with the namespace being: 'http://www.external.com/customNS', would the receiving end fetch that namespace? I think logically the answer is yes (unless there are rules that prevent fetching from external sources) but I need to verify this.

Question 2: just in case the answer is yes for the first question, reason I am asking is I have a task dealing with Onvif at work, which uses XML to send commands to IP cameras, and when the onvif XML namespace servers went down (Dec/28), some requests started failing, but I need to make sure this was the cause instead of faulty requests, so do you think cameras actually have the namespaces pre-loaded, and do absolutely no external fetching, or do they just fetch them on at least the first time a request with the specific namespace is received? I tried creating a server, and sending it to the camera as a namespace, but I didn't receive any requests, but this might just mean that the camera rejects requests with servers that aren't onvif's.

Example request I send to the camera (without header and footer):

Using ONVIF, how can I determine if the device has a fisheye camera and subsequently if it supports dewarping stream?

I am working on a script to extract info from a CSV file and paste it into a .txt file. After I have that text extracted a run that txt file through a script that is supposed to remove any duplicates. Each row of data has a lot of information. Every row should have an IP Address and MAYBE a Logical ID. here is a sample of my csv file.

I have a bunch of CSV files with the name (modelnumber)_filter. The user is asked which model they are searching for so
example user input : "1.3C-H4SL-D1" So then the file path will be loaded:

"C:\Users\ADMIN-SURV\Desktop\data_pull\1.3C-H4SL-D1_filter.csv"

EX CSV

NEW Update 11:30am CST Below is my full code

Desired results would be a txt file in this format:

Logical ID: (&) 192.168.xx.xxx (if it has both)

192.168.xx.xxx

Logical ID:

192.168.xx.xxx

192.168.xx.xxx

Logical ID:

Logical ID:

192.168.xx.xxx

**Latest Code-> I want to print the LOGICAL ID if one exists, if not I want it to print the IP Address (to a new form)

The code shows that I have specified a model.csv to write to a model.txt and have to manually change it model by model. So if there is a fix for that that would be great too

I'm consumning this ONVIF service: https://www.onvif.org/ver10/media/wsdl/media.wsdl using Visual Studio 2019, which automatically generates a client wrapper from the WSDL file.

I cannot figure out how to use the 'Extension' element of OSDTextConfiguration to add an element to OSDTextConfiguration which has not been specified in the WSDL.

I have a project that requires the program to stream in metadata in a form of XML. I have tried various way found online to iterate through the XML but I only managed to print out the inner text of the XML.

How can I iterate through the XML and get the value for tt:object "ObjectID" and its child "Gender"?

This is an example of the XML.
