Using multi-channel audio support causes memory leaks

[OlafZwe]

A (native) memory leak occurs when using the following setup: Enabling all audio channels by initializing the decoder with enableAllAudioCh = true. Pulling that multi-channel audio data using the C# function getAllAudioChannelData.

This memory leak appears to occurs both when testing in the Unity editor, as well as in a standalone Windows build of the Unity app.

Hi OlafZwe, Thanks for the feedback. I'll check and fix it.

Hi, I had tried, but I can't find memory leak. Could you help to provide more details and the test video? Thanks.

To reproduce the memory leak (and CPU usage spike), make the following changes to the Demo scene:

• Remove all but the 360Video and Camera objects
• Point the VideoSourceController component in 360Video to any .mp4 file with audio track
• in VideoSourceController.cs, change line 62 to: decoder.initDecoder(fileSeeker.getPath(), true);
• in VideoSourceController.cs, add the following Update function:

  public void Update()
  {
  if (decoder != null && (int)decoder.getDecoderState() >= 3)
  {
      float[] audioBuffer;
      double time;
      int samplesPerChannel;
      decoder.getAllAudioChannelData(out audioBuffer, out time, out samplesPerChannel);
  }
  }

Running this Demo scene spikes CPU and memory usage, and this usage does not go down when stopping the scene in the editor.

I do the same thing but the memory usage didn't raise over time. So I think it may be not an issue of memory leak. I'll keep monitoring it, thanks.
