When the video is at begening, call GetCurrentTime not return 0

Problem description:

When the video is at begening, call GetCurrentTime not return 0. (Even after SEEK(0)) Is it a bug? Do you have an option to abstart this offset?

Device (which devices are you having the issue with - model, OS version number):

Windows 10 Profesional 10.0.19044

Media (tell us about your videos - number of videos, resolution, codec, frame-rate, example URLs):

I tried with one video you provide : BigBuckBunny-360p30-H264.mp4 Begin at 0,1333332 secondes GetDuration = 7,97 (If I remove 0,1333, it's exactly the size I got in my video editor) My video Editor is Wondershare Filmora

System Information:

AVPro Video: v2.6.6 (plugin v2.6.3f1-core) Target Platform: Standalone Unity: v2021.3.7f1 WindowsEditor OS: Desktop - System Product Name (System manufacturer) - Windows 10 (10.0.19044) 64bit - French CPU: AMD Ryzen 5 2600X Six-Core Processor - 12 threads - 16317KB GPU: NVIDIA GeForce GTX 1660 SUPER - NVIDIA - Direct3D 11.0 [level 11.1] - 5991KB - 16384

Hi @LimitlessMan36,

1. GetDuration will return the longest track duration, which in the case is the audio track.

2. GetCurrentTime should return 0 at the start. I have read about weird time offsets occurring in Windows 10 and some information points to B-frames. If you're using FFMPEG and H.264 codec then you can encode without B-frames via: -x264-params "bframes=0" Could you re-encode and see what you get?

3. What do you get with GetTextureTimeStamp?

[LimitlessMan36]

Thank you Chris-RH, Realy clear answer.

Unfortunately, I can,t re-encode my video because I create a kind of video player.

I don't find GetTextureTimeStamp anywhere in your asset. Where can I find it?

[LimitlessMan36]

Ok, I find it.

With GetCurrentTime : 0.0667332 With GetTextureTimeStamp : 667332

So same result.

While waiting for a more elegant solution (if we find a solution) I created a temporary class. I save the initial offset and I send the corected value :

public class MyVideoPlayer { private double _timeOffset;

private MediaPlayer _mediaPlayer;
private bool getBeginingOffset = false;

public MyVideoPlayer(MediaPlayer mediaPlayer)
{
    _mediaPlayer = mediaPlayer;
    _mediaPlayer.Events.AddListener(HandleEvent_MediaPlayer);        
}

public void Init()
{
    getBeginingOffset = true;
    _mediaPlayer.Control.Seek(0);
}

public double GetCurrentTime()
{
    return _mediaPlayer.Control.GetCurrentTime() - TimeOffset;
}

public double GetDuration()
{
    return _mediaPlayer.Info.GetDuration() - TimeOffset;
}

public void Seek(double time)
{
    _mediaPlayer.Control.Seek(time + TimeOffset);
}

void HandleEvent_MediaPlayer(MediaPlayer aVPro, MediaPlayerEvent.EventType eventType, ErrorCode code)
{
    // When Init MyVideoPlayer, a Seek(0) command has send to get the begining offset
    if (getBeginingOffset && eventType == MediaPlayerEvent.EventType.FinishedSeeking)
    {
        _timeOffset = _mediaPlayer.Control.GetCurrentTime();
        getBeginingOffset = false;
    }
}

}
