DisplayUGUI not showing correct last frame when video was played with some hard lags using NotchLC codec

[Crazy-BAD]

Describe the issue We using RGBA video for ui background. On some hard workload (for example app start) video was freezed not on last frame which difenetly incorrect. Also i was tryed to subscrive media to player events and seek to last frame after video playback finished. This also not solwed issue.

Your Setup (please complete the following information):

• Unity version: 2020.3.11
• AVPro Video version: AVPro Video v2.1.3 (native plugin v2.1.3f1-ultra) on NVIDIA GeForce GTX 1080 Ti/Direct3D 11.0 [level 11.1] (MT True) on WindowsEditor
• Operating system version: W10
• Device model:
• Video specs (resolution, frame-rate, codec, file size): Video: NCLC 800x800 29.97fps 19297kbps

To Reproduce

1. play video without loop. last frame fully clear - i.e. all content removed by alpha channel.
2. make script with random hard lags.
3. sometames vide was stopped with image on screen (non last frame)

script that was used to attempt to fix issue (but unsuccessful) public class MediaPlayerEndFrameFix : MonoBehaviour { private void Start() { var meidaPlayers = gameObject.GetComponentsInChildren(true); foreach (var mp in meidaPlayers) { mp.Events.AddListener(OnMediaPlayerEvent); } }

    private void OnMediaPlayerEvent(MediaPlayer sender, MediaPlayerEvent.EventType ev, ErrorCode code)
    {
        if ( ev == MediaPlayerEvent.EventType.FinishedPlaying )
        {
            var totalTime = sender.Info.GetDurationFrames() / sender.Info.GetVideoFrameRate();
           UnityEngine.Debug.LogWarningFormat("Force seek form [{0} to {1}] - [{2}]", sender.Control.GetCurrentTime(), totalTime, sender.gameObject.GetPathInScene() );
            sender.Control.SeekToFrame(sender.Info.GetMaxFrameNumber());
        }
    }
}

Could you please send us this video file to unitysupport@renderheads.com or attache it here if it's not too large.

This seems to be a bug. We will investigate this.

Thanks,

simple way to reproduce - in update use Sleep(x), x is public variable in monobeh (checkd in range 1000-10000) to allow change delays without player restart. in this case i also saw other different bugs, every playback (manual press pause\play) in editor - even with normal fps (>60, delay was removed) video ended incorrectly not with last frame, until video manually was reloaded (in editor\player by pressing button). but this case reproduce not checked.

Thanks for the video and the reproduction steps. This seems like a genuine bug so we should be able to fix it pretty fast.

[Crazy-BAD]

thanks, we need this fix, i hope you can fix this fast.

[AndrewRH]

While we look into it, could you try enabling the Low Latency option, and make sure you have Use Custom Mov Parser disabled?

Does this workaround solve your issue?

Meanwhile we'll continue to look into the root cause..

Thanks,

[AndrewRH]

Thanks for reporting the issue and for your patience while we fixed it.
