Unity: Live Video Streaming ARCore Camera Texture

I'm trying to use TCP sockets to stream the texture from the ARCore camera on one device to the background image on another device. I've found some great resources that have got me close. This question helped me a lot: Unity: Live Video Streaming
The only difference is that this example uses a WebcamTexture, which I've got working without any lag and smoothly.
However, obtaining the camera texture from ARCore is a bit of a different process. I think I'm doing this correctly but maybe I'm missing something. When I run this with the ARCore camera texture and my minor changes, the server lags significantly.
Below is my code. I made no changes to the client side code so I know it has to do with my server side changes.

Microphone input's maximum float number is 1. How to make it bigger and change it from 1? Unity C#

I have a code that takes a microphone input(when pressing "T)" and returns it as a float number (one final float number). However, when I yell or blow into microphone the maximum float it prints is 1 and no matter how I yell or say quietly after it printed 1, it keeps printing 1 only. How to change it to a bigger number. Let's say if I yell it would return a bigger number than if I just say quietly.

The sensor returns only a 0 or a 1, it's not 0->inf, if you want to something else, like checking how load is the voice from 0 to 100, you could record it and check the audio file highest bump and return that.

Unity double click(keyboard) with Time.deltaTime [duplicate]

This question already has answers here:
Unity Input detected multiple times in a press
(2 answers)
Closed 5 years ago.
I'm Unity starter and wanna make game that
ROTATE with ↖(7), ↗(9) (need double pressing also)
MOVE with ↑↓←→ on numpad 8,5,4,6 (double and also need something like ←↑→+Q)
.
I need to detect double input like ↗↗ at exact time and count
but sometimes it detected twice even if I double press only once...
this is part of my C# script. (full src is included under)
void Update () {
//get input
is_r = Input.GetButton ("Keypad9");
is_l = Input.GetButton ("Keypad7");
is_rr= false;
is_ll= false;
if (is_r) {
float gap = Time.time - time_r;
if (Time.deltaTime + 0.05 < gap && gap < time_maxgap) {
//seems like if Time.deltaTime change more than 0.05sec it works wrong
is_rr = true;
print ("deltatime = " + Time.deltaTime + "gap = " + gap);
}
time_r = Time.time;
}
// and more codes below
I think it's because of Time.deltaTime is diffrent for all frames.
And similer problem happened in movement(↑↓←→) command input too. (I'd like to start dash with ↑↑) It sometimes detected twice even if I make source in diffrent style.
If you know HOW TO FIX this problem OR BETTER SOLUTION to avoid problem, please help me. (and i'm not good at english)
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CameraInputFilter : MonoBehaviour {
float time_maxgap = 0.3f;
float time_r = 0f,
time_l = 0f;
bool is_r = false,
is_l = false,
is_rr= false,
is_ll= false;
// Use this for initialization
void Start () {}
// Update is called once per frame
void Update () {
//get input
is_r = Input.GetButton ("Keypad9");
is_l = Input.GetButton ("Keypad7");
is_rr= false;
is_ll= false;
if (is_r) {
float gap = Time.time - time_r;
if (Time.deltaTime + 0.03 < gap && gap < time_maxgap) {
is_rr = true;
print ("deltatime = " + Time.deltaTime + "gap = " + gap);
}
time_r = Time.time;
}
if (is_l) {
float gap = Time.time - time_l;
if (Time.deltaTime + 0.01 < gap && gap < time_maxgap) {
is_ll = true;
}
time_l = Time.time;
}
//send out result
if (is_rr) {
print ("rr");
} else if (is_ll) {
print ("ll");
} else if (is_r && ! is_l){
print ("r");
} else if (is_l && ! is_r){
print ("l");
}
}
}
this code is made in difrent style.

Not sure, but try Input.GetButtonDown instead of Input.GetButton.
Input.GetButton will be true while you hold a key pressed, so it can be cause of your "double detection".

Xamarin Urho IOS how to set up an application?

Unity Android Google Play Services - Sending A String Message

I make a game for Android using Unity Engine and i use google play game services for multiplayer. I have a problem when i sending a string message to other player. I can send it but other player cant recived it.
Send Code:
public void SendMyUpdate(float posX, float posZ, Vector3 velocity, float rotY, float weapon, string opponentId)
{
DebugConsole.Log("OppenentSend " + opponentId);
bytesize = opponentId.Length * sizeof(byte);
_updateMessageLength = 26 + bytesize;
_updateMessage.Clear();
_updateMessage.Add(_protocolVersion);
_updateMessage.Add((byte)'U');
_updateMessage.AddRange(BitConverter.GetBytes(posX));
_updateMessage.AddRange(BitConverter.GetBytes(posZ));
_updateMessage.AddRange(BitConverter.GetBytes(velocity.x));
_updateMessage.AddRange(BitConverter.GetBytes(velocity.z));
_updateMessage.AddRange(BitConverter.GetBytes(rotY));
_updateMessage.AddRange(BitConverter.GetBytes(weapon));
//_updateMessage.AddRange(BitConverter.GetBytes(opponentHp));
_updateMessage.AddRange(System.Text.Encoding.UTF8.GetBytes(opponentId));
byte[] messageToSend = _updateMessage.ToArray();
PlayGamesPlatform.Instance.RealTime.SendMessageToAll(false, messageToSend);
}
Recived Code:
public void OnRealTimeMessageReceived(bool isReliable, string senderId, byte[] data)
{
// We'll be doing more with this later...
byte messageVersion = (byte)data[0];
// Let's figure out what type of message this is.
char messageType = (char)data[1];
if (messageType == 'U' && data.Length == _updateMessageLength)
{
float posX = BitConverter.ToSingle(data, 2);
float posZ = BitConverter.ToSingle(data, 6);
float velX = BitConverter.ToSingle(data, 10);
float velZ = BitConverter.ToSingle(data, 14);
float rotY = BitConverter.ToSingle(data, 18);
float weapon = BitConverter.ToSingle(data, 22);
//int opponentHp = BitConverter.ToInt16(data, 26);
string opponentId = System.Text.Encoding.UTF8.GetString(data);
// We'd better tell our GameController about this.
if (updateListener != null)
{
updateListener.UpdateReceived(senderId, posX, posZ, velX, velZ, rotY, weapon, opponentId);
DebugConsole.Log("OppenentRecived " + opponentId);
}
}
else if (messageType == 'F' && data.Length == _finishMessageLength)
{
// We received a final time!
float finalTime = System.BitConverter.ToSingle(data, 2);
//Debug.Log ("Player " + senderId + " has finished with a time of " + finalTime);
}
This got this code from

You should remember to add an index of where the converter should find the byte range
ie: string opponentId = System.Text.Encoding.UTF8.GetString(data, int index);
