AudioSampleProvider's buffer overflow on 360 Video

Hi all !

I've a weird issue : I've made an app for playing 360 video, most of them in 4K (4096x2048), some of them a little smaller.

When I launch the app for the first time (meaning, after boot or reboot the phone), sometimes, the video freeze, but the sound continue (the sound is uncluded in the MP4 file). The app itself is not freezed (actions planed at the the end of the video works well).
The sound is also a bit delayed from a few frames.

Just before the video freeze, the logcat show several

AudioSampleProvider's buffer overflow. xxx sampe frames discarded

The app replay the video after the HMD has been unmounted, and from there, no issue at all, never (sound is synchronize, video never freeze).

This behaviour occurs both on S7 phone with Gear VR and Oculus Go.

The video is project via a skybox panoramic shader with renderTexture, here is the code :

Code (CSharp):

1.     void Start () {
2.    
3.         OVRManager.HMDMounted += HandleHMDMounted;
4.         OVRManager.HMDUnmounted += HandleHMDUnmounted;
5.  
6.         videoPlayer = videoPlayerObj.GetComponent<VideoPlayer>();
7.         videoPlayer.url = Application.persistentDataPath + "/video.mp4";
8.         videoPlayer.EnableAudioTrack(0, true);
9.  
10.         audioSource = gameObject.AddComponent<AudioSource>();
11.         audioSource.playOnAwake = false;
12.        
13.         videoPlayer.playOnAwake = false;
14.         videoPlayer.SetTargetAudioSource(0, audioSource);
15.         videoPlayer.Prepare();
16.         videoPlayer.loopPointReached += EndReached;
17.         videoPlayer.prepareCompleted += PlayerReady;
18.        
19.     }
20.  
21.     void PlayerReady(VideoPlayer vp)
22.     {
23.         //Play Video
24.         videoPlayer.Play();
25.         audioSource.Play();
26.  
27.     }
28.  
29.     void EndReached(VideoPlayer vp)
30.     {
31.         videoPlayer.frame = 0;
32.     }
33.  

Think of an issue related to decompressing the audio in Unity (because works well after first read), but don't know how to solve this !

Thanks

 

Hey! I am also getting overflow errors suddenly. Everything was working fine before. Any luck with solutions?

 

Hi, unfortunately, still stuck on this

 

I've got the same problem! still no solution

 

I have the same problem.2018.3.13f1

 

I have the same problem. Unity 2019.1.8
Any luck on your end gentlemen?

 

have a similar issue aswell

 

I don't use VR，I have the same problem. Unity 2018.4.2f1.

 

I was able to fix this by clicking 'wait for first frame' on the video player.

 

Didn't work.
Still facing the same issue on unity 2019.3.5f1

 

I also have this problem, when streaming from AWS, did anyone find the solution?

Edited:
I found this thread on this exact topic. You should look at the explanation. I'll tell you later if this works for me.
