Why does AudioSource.time return Infinity in Unity 5.3?
I have a MovieTexture file in my project, and I want to keep track with the time based on the audio time. It works fine in Unity 5.1, but when I switch to 5.3, the AudioSource.time just returns Infinity. Does anyone know what has been changed. Here is a snippet of my code. Thank you!
public void processVideoFile(){
GameObject.Find("Video Frame").GetComponent<RawImage> ().texture = movie as MovieTexture;
audio = gameObject.GetComponent<AudioSource> ();
audio.clip = movie.audioClip;
movie.loop = false;
videoIsProcessed = true;
}
void LateUpdate () {
if (videoIsProcessed) {
if (!movie.isPlaying && !pausing) {
gameObject.GetComponent<LessonManagerScript>().loadVideo(gameObject.GetComponent<LessonManagerScript>().currentButton);
playButton.gameObject.GetComponent<Image> ().enabled = true;
}
if(!pausing){
timeStamp = audio.time + timeOffSet;
}
Debug.Log("Audio time is: "+audio.time+" and timeStamp is: "+timeStamp);
}
}
I found a workaround it! I used a Stopwatch from System.Dianogtics to replace the audio.time.
However, this is a bug from Unity 5.3 (I'm pretty sure).
I also do have that exact same bug.
Is there anyone else affected by this?
That's pretty annoying.
At the moment AudioClip.frequency seems to return 0 for MovieTextures.
This probably causes AudioSource.time to return "infinity".
I assume that AudioClip.frequency should return 48000 for MovieTextures, so you can create your own, corrected, version for now:
public AudioSource audioSource;
const int CLIP_FREQUENCY = 48000;
void Update () {
float time = audioSource.timeSamples * 1f / CLIP_FREQUENCY;
}
