QUESTION
I'm trying to receive RTP stream encoding h264 over TCP from my intercom Hikvision DS-KH8350-WTE1. By reverse engineering I was able to replicate how Hikvision original software Hik-Connect on iPhone and iVMS-4200 on MacOS connects and negotaties streaming. Now I'm getting the very same stream as original apps - verified through Wireshark. Now I need to "make sense" of the stream. I know it's RTP because I inspected how iVMS-4200 uses it using /usr/bin/sample
on MacOS. Which yields:
ANSWER
Answered 2022-Feb-09 at 09:52Going for mp4 container wasn't a good choice after all. It turns out the RTP essentially yields raw h264 stream. To inspect its structure I converted the genuine mp4 recording to .264 like this:
QUESTION
I have a longer list whose elements are multi-character symbols, for example:
@c = qw(iim v7 v7 iM iv7 iM im iv7 iv7 bviiM im biio iim bviim biiM biim bviM bviM ivm iih v7 v7 v7 iiim iiih vi7 iim v7 v7 iM iv7 iM im iv7 bviiM im biio iim bviim bviim iiio iim v7 v7 v7 vm i7 ivM iiih vi7);
I'd like to find the indices in this list that match sub-lists of the type S1+ S2+ S3+, where the "+" means match one or more times. So, for example, the sub-list pattern (im iv7 bviiM)
would match both (im iv7 iv7 bviiM)
and (im iv7 bviiM)
as highlighted in bold above. The code would provide the indices 6, 7, 8, 9 for the first match and 32, 33, 34 for the second.
On the surface, this doesn't seem like it should be difficult, and I've tried implementing this with a variety of methods, including regexes, but so far it has beaten me. If there's a simple way to do this I'd be grateful for any help.
...ANSWER
Answered 2021-Dec-19 at 10:09An interesting problem, because repeated elements need also be matched by items from the given sub-sequence while the order need be maintained.
QUESTION
Hi everyone so Im in the process of developing a checkout system. Right now it works fine checking out one item at a time but I would like to be able to checkout multiple at a time using select2 jquery. I have it setup but for some reason my List Items property is returning null instead of storing the items that Im trying to check out and I cant seem to find the fix. Hoping someone can help me out here.
Here is theModel Class and View Model that I have tried:
...ANSWER
Answered 2021-Nov-15 at 03:26I don't see where your Items property is being instantiated, and if it isn't, then it will definitely be null.
You can instantiate it in a constructor:

I have a view with an ajax call:
...ANSWER
Answered 2021-Sep-14 at 09:21You cannot use RedirectToAction
to action in an ajax call to redirect the entire page. Because the ajax response is limited to the ajax request scope only.
What you can do is return a json object instead of RedirectToAction
like this:
QUESTION
I'm currently using this timescaleDB integrated with postgresql13, I found this patch called incremental view maintenance which i think is also very important for my project
https://github.com/sraoss/pgsql-ivm
can pgsql-ivm be possibly be installed in postgresql13? So that I can use both of them at them same time?
...ANSWER
Answered 2021-Sep-13 at 02:34That's probably a PostgreSQL version with this patch applied.
This has been under discussion for a while, but didn't make it into the source tree so far.
I wouldn't dare use that yet, unless I have good reason to trust the code and am ready to take care of that patch and apply it to PostgreSQL for each new update.
My advice is to roll your own using a regular table and triggers.
QUESTION
ANSWER
Answered 2021-Jun-04 at 11:20You just have to identify those elements (and I think you can do so using the class with a css selector), then loop through the elements and append the text to the appropriate array.

I have a controller in my .Net Core 3.1 app that calls another controller action. Before I added a RedirectToAction
in the called controller everything worked fine. I now want that controller to redirect to an error page if appropriate, otherwise back to where it was called in the original controller.
Here is the code in my controller:

QUESTION
I have a simple table view cell containing two labels whose positioning constraints disappear at runtime (the width and aspect ration remain). There are no warnings, no errors in the storyboard view, no console log and I don't use size classes.
The views are misplaced (they stick to the top left corner) and when I launch the Debug View Hierarchy there is an exclamation mark on a purple background indicating an ambiguous position. Upon inspection it turns out that the position constraints are not there anymore.
I have tried removing and adding them again, I have compared almost every IB inspector in the view hierarchy with a working implementation and couldn't figure out a difference. I have inspected the views with lldb and the _autolayoutTrace doesn't show the constraints.
I know I can remove the controller in Interface Builder and rebuild it but I would appreciate an insight into debugging that kind of issue.
Here is the part of the storyboard describing the table view controller and prototype cell :
...ANSWER
Answered 2020-Feb-19 at 15:18OK, that was not obvious... until it was :)
Somehow - either by an "oops" click or some Xcode / IB quirk - your cell's Content View
got its class set to CheckListItemCell
:
Select the cell's Content View
, go to the Identity Inspector pane, and change the Custom Class
back to the default UIView
:
