conferences | curated list of conferences | Awesome List library

I'm having an issue with a project i'm working on for my brother's company and wanted to see if anybody had any ideas on how to fix it.

The company puts on virtual conferences for corporate events, nonprofits, etc. and its common with these things for people to need to pre-record their presentations with a powerpoint slideshow. For non-tech savvy clients (which is most of their clients), the only way to make this happen is to hire a contractor to work with with the client 1 on 1 to get their video recorded. My goal is to make a site where clients can easily record the video and slideshow themself, which would reduce their costs significantly.

Its still very much a work in progress, but what i have so far is live here: https://ezav-redesign-hf4d3.ondigitalocean.app/

The issue is, while the recording function works really well on Firefox, on Chrome it always ends up with no audio. You can see the full source code at the live site, but here is what I think should be the relevant part:

My application has a method to update a conference. After doing so I have a modelandview with a redirect to the main conference list. This all works fine although the message which I add as an object to the modelandview does not display.

My method in my controller:

I am using https://github.com/twilio/video-quickstart-js to run a video conference project. I want to allow users to join without a camera. So, they can only use a mic.

With Twilio video conference, user can join video conferences without a camera?

I've set up a service account from which i created events and added the hangout meet, so i could get the link to share. It has worked till this morning and now i am receiving invalid conference type error, nothing has changed in my code. Can you help me out? This is the request that has always worked:

I've been experimenting with using the Bootstrap Navbar. So far I'm pretty happy with the results for my webpage's navigation. I have a lot of links and it displays them in a nice way. The only problem is that the nav links don't look evenly distributed. Here is the condensed code for the navbar. View it in full screen, otherwise the nav-items stack.

I'm trying to test AVAudioEngine, watched the WWDC conferences about it, and did everything by the book to try to play a simple file.

Despite everything being exactly the same as in the samples that I found (WWDC and a few other places), despite everything seeming fine (no error, seems to be running), I have no sound output.

Here's the code:

I'm looking for a way to generate a Conference resource within the Twilio system before adding anyone to that conference.

The official recommended way to start a Conference is by returning TwilXML in response to a Twilio callback. This can either be done in response to someone calling a Twilio number or, in a somewhat indirect way, by making a call and returning TwilXML which will connect the person to a conference once they pick up. All of the APIs to modify conferences use the ConferenceSID as the handle to decide what conference to change. The problem with both of these methods is that they do not give you the ConferenceSID until you receive a callback.

Unfortunately callbacks do not contain any identifying information about who generated them. They do have a ConferenceSID (identifying the conference), and a CallSID (uniquely identifying the call connecting the caller to the conference). When you get your first callback, there appears to be no way to be able to match either of those identifiers. If you start multiple conferences and get two callbacks with different ConferenceSIDs and different CallSIDs, it is inconvenient to tell which conference is generating which callback.

That's why it would be easiest to create a conference resource and then use the versatile add participant call. This would simplify the entire backend flow for using conferences by starting with the ConferenceSID and going from there.

P.s. To head off other suggestions - there are ways around this. You can specify different callback URLs for different conferences. You can specify different friendlyNames for different participants which you can match in your backend. It's totally possible to work with, but I would like something cleaner, which would require making conferences before anyone is called.

I'm trying to understand how I can generate and attach to a Google Calendar Event a Google Meet istance in PHP.

The documentation (https://developers.google.com/calendar/create-events#conferencing) is not clear about this part, the classes and methods for PHP are documented (https://developers.google.com/resources/api-libraries/documentation/calendar/v3/php/latest/class-Google_Service_Calendar_CreateConferenceRequest.html) so they exist. In the documentation there is a javacript example but I don't get how to translate it into php code.

I did some googling but no one else seems to had this necessity before.

UPDATE: I think I've found the problem. The javascript documentation reports that the setDocumentDataVersion(1) is required to allow to process the Meetings.

Here a brief doc about its use:

Version number of conference data supported by the API client. Version 0 assumes no conference data support and ignores conference data in the event's body. Version 1 enables support for copying of ConferenceData as well as for creating new conferences using the createRequest field of conferenceData. The default is 0.

This method doesn't seem to exist in the PHP API, so I cannot set it to 1. That's may why my code fail to attach a google meet to my event.

Here my test code. Till here it works fine and it creates an event in my calendar.

UPDATED: The sample code listed below is now complete and sufficient to generate the shadow alternate key in Conference. When the Meeting entity inherits from a base entity containing a RowVersion attribute the shadow alternate key is generated in the Conference entity. If that attribute is included directly in the Meeting entity, without inheritance, the shadow alternate key is not generated.

My model worked as expected in EF Core 3.1. I upgraded to .Net 5 and EF Core 5, and EF adds shadow alternate key attribute(s) named TempId to several entities. EF can't load those entities unless I add those attributes to the database. The shadow alternate key properties are NOT used in any relationships that I can find in the model. Virtually all discussion of shadow properties is either for foreign keys or hidden attributes. I can't find any explanation for why EF would add a shadow alternate key, especially if it doesn't use the attribute. Any suggestions?

One of the entities that gets a shadow alternate key is Conference, which is the child in one relationship and the parent in another. I have many similar entities which do NOT get a shadow alternate key, and I cannot see any difference between them.

I loop through the model entities identifying all shadow properties and all relationships using an alternate key for the principal key. None of the shadow alternate keys are used in a relationship. I do see the two defined relationships where I specifically use an alternate key, so I believe my code is correct.

Here is a complete simplified EF context and its two entities which demonstrates the problem.
