QUESTION

Can I emulate a IP Network Camera as a Media Device that is detected by Chromium?

Asked 2020-Apr-09 at 08:24

I have a WebRTC solution based on Chromium browsers which uses local device cameras. However the cameras are mounted at a significant distance and cannot be connected to any PC via USB. They can be connected into the LAN via ethernet cables.

Is there any way to emulate the cameras as a local media device so that navigator.mediaDevices.enumerateDevices recognises them? Can I change the code or use any APIs to the detect IP cameras? Any pointers would be greatly helpful.

I have tried the options:
1. Add device in Windows Settings. Did not work as it requires specific Windows Insider update.
2. IP Camera Adapter, ManyCam, iSpy did not work as they all support HTTP. My HD cameras only support RTMP protocol.

v4l2loopback is one way you could do this! This allows you to feed a virtual webcam on Linux with arbitrary media.

Then you could have a pipeline in GStreamer that looks like

You need to declare datatable and add data columns only once outside foreach loop.

Complex Database Queries in yii2 with Active Record

Asked 2017-Jan-14 at 12:33

TL;DR I have a query that works in RAW SQL but i have had little success recreating it with query builder or active record.

I originally wanted to allow the user to modify (filter) the results by means of a search form(user & date), however i have since realized that implementing filters on the gridview with active records would be smoother.

I have gotten simple queries to work however am unsure of how to implement one with this many joins. Many examples used sub queries but my attempts failed to return any records at all. I figured before I attempt filters i need to transcribe this query first.

My recommendation would be to have 2 queries. The first one to get the ids of the videos that fit your search, the second query theone that uses those ids and feeds your $dataProvider.

Yii2 Gridview Displaying 4 identical Pages of Results

Asked 2017-Jan-12 at 23:46

I am working on a web application based off of the yii2 advanced application template. I have written a database query and implemented it with findbysql() returning the correct records via a grid-view generated from the gii CRUD. However for some reason 4 pages of identical results are returned. Each page is showing identical primary keys (1-10) in order, while the element index increases linearly across all 4 pages (1-40).

I have commented out the action column so i figured i did not need to include the CRUD .php files

The problem is that the pagination needs SQL modifier offset which has no effect on the result of findBySql. See the Yii doc.

You have to use $_GET['page'] and $_GET['per-page'] in your controller, e.g.:
