Remote offer sdp: Failed to set remote video description send parameters - webrtc

I am using Simple Peer to connect 2 clients over webRTC
While trying to send the offer to the receiver I am getting
Failed to set remote video description send parameters.
Here is the SDP

If there is any tool to format it, please let me know, I will do it.
also, I read, that this could be a codec problem, so I tried to replaced profile-level-id=42001f with
profile-level-id=42e01f this did not do the trick.
Why does webRTC have to be so difficult? it might as well be called hellRTC
also, why is the extension part of the SDP is full of URLS?.. it just doesn't look something you want to pass in your request or signaling.
Thank you.

Pandas: how to add a column with a value based on conditions on differents columns

I'm analyzing a dataset of internet communictions that consists of 5 columns and below an example of it

I would like to get the same dataset but with a new columns Length 2, where Length 2 is the value of the row that match those conditions:
IPSrc = IPDst
IPDst = IPSrc
PortSrc = PortDst
PortDst = PortSrc
So in this example, the ideal results would be:
IPSrc
IPDst
PortSrc
PortDst

Length 2

Knowing that the dataset contains 1 million rows, it would be appreciated if the given answers would considerate the performance.
Thanks in advance :)

Use DataFrame.join with matching column converted to index with columns in parameter on:
df = df.join(df.set_index(['IPSrc','PortSrc'])['Length'].rename('Length 2'),
on=['IPDst','PortDst'])
print (df)

Does anyone know why the offer is not working for chrome, but it's fine for firefox and safari?

000#ABC.COM 000000 1.1.1.1
000#ABC.COM 000001 1.1.1.2
I want to create a table on top of that data table, which has the master ID. The rule is as long as one of each attribute (Email, Phone, IP) is matched then they will have the same master ID.
For example:
EMAIL PHONE IP Master_ID
123#ABC.COM 123456 0.0.0.0 1
123#ABC.COM 123456 0.0.0.1 1
123#ABC.COM 654321 0.0.0.0 1
321#ABC.COM 123456 0.0.0.0 1
000#ABC.COM 000000 1.1.1.1 2
000#ABC.COM 000001 1.1.1.2 2
Is there any suggestion on how can I get it done by just using query/function in Oracle?

how change G722 to PCMA codec?

Im using FreeSWITCH-mod_sofia/1.6.9~64bit + SIPJS library (http://sipjs.com/) + Chrome Version 52.0.2743.116 (64-bit).
When I make a call logs shows me codec G722. How to change it on webrtc preferences to PCMA?

The 1st SDP looks like its from FS server to Browser. Try setting inherit_codec before bridge in FS dial plan.
If late negotiation is on, and you set inherit_codec=true on the A leg, the negotiated codec of the B leg will be forced onto the A leg.

how-to tunnel a secure websocket (wss://) to insecure websocket (ws://) ( stunnel ? ) on linux

I have an ancient socket server script, which can only use unsecure ws:// sockets.
I upgraded my site to use https:// , and websocket connections to ws:// are not possible anymore, browsers generate an error message, that the connection is blocked and that i have to use wss://
I am using linux(centos). Is there any easy was to setup a tunnel from wss:// to ws:// on 2 ports?
I have found stunnel, but i can't get it to work properly, is there maybe an other way to do this?
What i tried to far with stunnel:
[websocket]
accept = 9301
connect = localhost:9300
and i also tried:
[https]
accept = www.flirtzo.eu:9001
connect = localhost:9000
But i have not been successfull. I hope anyone knows a proper solution or fix. Thank you very much.
[edit]

Regards Arjan

Answer based on the last pcap, for details see discussion at the question:
The client simply closes the connection after a successful handshake without sending any data. Since I don't see a server name extension in the ClientHello I assume you access the server as IP and not hostname, in which case the client will probably not accept the certificate (because name does not match). Although I would expect the browser to log such things to console.
So it looks like hostname validation was the real issue and changing from wss://ip to wss://hostname solved the problem.
