I’m using U3D 2018.3.10f1 on Ubuntu OS, and the stackoverflow happend when implement OnAudioFilterReader .
Source code :
using UnityEngine;
using System;
using System.IO;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using System.Threading;
public class AudioRenderer : MonoBehaviour
{
private int rateZIME = 0;
private short[ ] buffer = new short[480];
private byte[ ] buffertoZIME = new byte[960];
private int frameLen = 960;
public bool Rendering = false;
void Start()
{
Rendering = true;
}
/// Write a chunk of data to the output stream.
public void Write(float[ ] audioData)
{
for (int i = 0; i < audioData.Length; i++)
{
i++;
if (rateZIME < 480)
{
buffer[rateZIME] = (short)(audioData * (float)Int16.MaxValue);
buffertoZIME[rateZIME * 2 + 1] = (byte)(buffer[rateZIME] >> 8);
buffertoZIME[rateZIME * 2] = (byte)(buffer[rateZIME] & 255);
rateZIME++;
}
else
{
rateZIME = 0;
IntPtr pFrame = Marshal.AllocHGlobal(frameLen);//Error happened
Marshal.Copy(buffertoZIME, 0, pFrame, frameLen);
}
}
}
// write the incoming audio to the output string
void OnAudioFilterRead(float[ ] data, int channels)
{
if (this.Rendering)
{
this.Write(data);
}
}
}
