In WebRTC, 'offer' must be generated by initiating peer (i.e. the caller) and shared with other peer (i.e. the callee) via signaling channel.

The other peer, of she wishes to answer, is supposed to generate 'answer' and send it back to initiating peer. Again, via signaling channel.

In this exchange it is clear who should be preparing which piece of data, and to whom it should be shared.

The next part of the ritual is the gathering of ICE candidates. Both peers will gather their own candidate slowly (trickle ICE) and on each discovered candidate, that candidate should be shared too. Sharing is also to be done via signaling channel

What is not clear to me here is at this point, who should be sharing candidates to whom?

Should caller share with callee? Or the other way around? Or both

I have a web.api action that accepts multipart/form-data via streaming, so it doesn't have any arguments:

I'm working on WebRTC streaming which streams video from a device to a browser. This streaming works in Chromium browsers just fine but fails in Firefox. There is a failure with the SDP exchange which then halts the rest of the connection (no ICE candidates sent after SDP exchange).

There are some issues with Firefox's answer SDP I've found but I haven't discovered a reason for the issues: SDP mentions VP8 but we use H264 only; m=video 0 has port 0 but typically that's non zero; I typically get an a=inactive line; a=sendrecv should probably be a=recvonly; many other lines are missing (for example, ICE-specific lines)

SDP examples below:

I have a web app that plays video broadcasted using WebRTC. I'm using a COTURN simple implementation (as described here: https://gabrieltanner.org/blog/turn-server). My turnserver.conf looks like this:

"Answer" of SDP offer is not sent to Web App(running on Windows/Mac/Linux) from Android/iOS application after updation of Chrome to latest v89 (released on 9 March 2021).

It is working fine on Chrome v88 and below.

I am writing an Angular front end for an API that occasionally serves Infinity and -Infinity (as bare words) in the JSON response object. This is of course not compliant with the spec, but is handled a few different JSON libraries, albeit optionally. I have an Angular service in place that can successfully retrieve and handle any retrieved entity that does not have these non-conforming values. Additionally, I have managed to get an HttpInterceptor in place which just logs when events trickle through, just to be sure I have it connected properly.

The issue that I am facing is that the HttpInterceptor seems to allow me to do one of two things:

• Catch/mutate the request before it is sent to the API, or
• Catch/mutate the request after it comes back from the API, and also after it is parsed.

What I would like to do is very similar to this question for native javascript, but I have not been able to determine if it is possible to tie into the replacer function of JSON.parse in the Angular Observable pipe (I think that if tying into that is possible it would solve my issue).

I have also found this question for Angular which is close, but they appear to have been able to handle changing the response to something other than the bare-words, which I don't have the liberty of doing.

This is the current implementation of my HttpInterceptor, note that it does not actually make any changes to the body. When retrieving an entity without these bare-word values, it logs to the console and all is well. When retrieving an entity with any of these bare-word values, an error is thrown before the HERE line is hit.

I want to set up a WebRTC datachannel and send some text. Therefore I create a RTCPeerConnection object with an "onicecandidate" and "ondatachannel" handler. (I keep "configuration" for RTCPeerConnection empty because connection is between localhost only.)

I am using a recursive CTE for "Groups" in a table using ID and Parent.

The first table "Groups" (Project_Estimate_Group) is hierarchical with ID and parent. The second table "GroupOptions" (Project_Estimate_Group_Option) accommodates a many-to-many relationship between Groups and Options. If you add an Option to any level it trickles down to any child in that branch.

I need to join the parent and recursive children of Groups to GroupOptions and have those joins "trickle" down through each recursion level so that at each level you have a join to the current Options as well as a join to the Options for each parent in the branch.

I need a row for each group without the OptionID and a row for each joined OptionID. Some levels will have no Options.

Can this be done with a recursive CTE?
