kandi X-RAY | ISAC Summary

ISAC is a Python library typically used in Telecommunications, Media, Media, Entertainment applications. ISAC has no bugs, it has no vulnerabilities and it has low support. However ISAC build file is not available. You can download it from GitHub.

Inventory Soft Actor Critic (ISAC) is an experimental extension of Inventory strategy described by Avellaneda and Stoikov[1]. Numerical simulations described in [1] have risk aversion parameter gamma configured arbitrarily. ISAC uses soft actor critic (SAC)[2] to control gamma. Two dimensional state space is defined with absolute value of inventory q and remaining time (total time - step * dt), while one dimensional action space is gamma. Reward is defined as a change in agents value (PL) discounted by penalty function. Penalty is proportional to volatility in mark to market value of inventory. Strategy is trained on 2000 simulated price paths containing 200 steps each. Benchmark is performed on 2000 simulated paths against inventory and symmetric strategy. Simulation settings are identical to ones described in [1]. Inventory and symmetric strategies have gamma configured to 0.1 as such setting produces most attractive PL profile for given simulation settings.

I guess you are trying to use firebase as a signalling medium and want to use react-native-webrtc for the video calling.

Here is the sample code I have for the same solution with the latest libraries and react-native version.

Just set up ios and android using this above link and then use the below code for reference.

The issue is caused by Chrome enabling extmap-allow-mixed by default (see https://www.chromestatus.com/features#offerExtmapAllowMixed). It can be solved by the receiver mangling the offer SDP to remove the line containing a=extmap-allow-mixed

QUESTION

WebRTC browser peerconnection depends on who creates an offer

Asked 2021-Feb-12 at 14:12

Two Chrome browsers: Alice (A), Bob (B). Different networks, so i'm using Coturn server (my own).

The problem is that when A creates an offer - everything is ok, ice connection state goes to "connected", everything works fine. But if B creates offer - every peer receives the same Ice candidates, but ice connection state after 10 sec "checking" goes to "disconnected". It depends on in what network is B. Only on some networks there is such problem.

Here are the details:

Not working case:

B creates an offer. His descriptor is:

ANSWER

Answered 2021-Feb-12 at 14:12

You are not getting any candidates with typ relay which means you are only using your TURN server as a STUN server. There are a couple of NATs where that can lead to a failure to establish the connection depending on who offers. There is an open bug in chrome's webrtc implementation for a couple of years now here

A working TURN server avoids the problem.

TypeError: Cannot read property 'cache' of undefined

I need help with "TypeError: Cannot read property 'cache' of undefined".

ANSWER

Answered 2021-Feb-06 at 07:12

It's very difficult to fully answer the question without knowing more about the problem, like what are other packages that you are using and the rest of the code.

By looking at the code you have provided the answer is there when you read the error message.

"TypeError: Cannot read property 'cache' of undefined"

Cache is a property of guild.members

And there is no such property called cache because there is no such object as members in guild

Since there is no such property as members it is undefined and you can't read a property called cache in an undefined object.

I suggest you to check what's returning in guild and to see if there is a members objects

When initializing jingle call we should send an IQ as shown below. I still don't understand the use of payload-type and which criteria to take into account in order to list them. I tried to read Supported media formats from android documentation but I did not see any relation with payload-type. After I read RTP payload formats, I some what understood what was a payload.

XMPP XEP-0167: Jingle RTP Sessions: Application Format speciications would be better place to look I guess:

The application format consists of one or more encodings contained within a wrapper element qualified by the 'urn:xmpp:jingle:apps:rtp:1' namespace (see Namespace Versioning regarding the possibility of incrementing the version number). In the language of RFC 4566 each encoding is a payload-type; therefore, each element specifies an encoding that can be used for the RTP stream, as illustrated in the following example.
