Video stalling after completing and can't be restarted

[heritageint]

Describe the issue Playing a video and allowing it to complete (fires the FinishedPlaying event) then attempting to replay the same file results in the file Stalling - have tried to rewind the file, seekToFrame, seekToTime, etc. and none work. Pressing Play then Pause then Play does restart the video.

The files are local on PC (StreamingAssets folder).

This can be recreated just in the Media Player component in the Editor - play a file and allow it to finish, try pressing Play and it stalls (and never plays).

Have tested in V2.9.3 and no issue, using the same project with V3.0.4 introduces the problem.

Your Setup (please complete the following information):

• Unity 2022.3.13f1:
• AVPro Core 3.0.4):
• Windows OS: Win11 Pro
• Device model: Intel(R) Core(TM) i7-13700K 32GB RAM RTX3060
• Video specs (resolution, frame-rate, codec, file size): Any file

To Reproduce

1. Load a video in the Media Player component
2. Play the video and allow it to finish
3. Press Play and the video stalls

Confirmed in MF and DS, not WinRT.

In the mediaplayer demo scene, it reaches the end of the clip and FinishedPlaying event occurs. Pressing the 'play/pause' button causes Paused event, pressing again causes Unpaused event, pressing again causes Paused event. Pressing 'play' a fourth time causes StartSeeking, Unpaused and FinishedSeeking events to occur and then the clip starts playing again. It works as expected in version 3.0.0

WinRT gets FinishedPlaying and Paused events at the end of the clip. 'Play' button restarts the clip from the beginning (no Seek events though).

Hi @heritageint,

Thanks for reporting this - I'm still looking into it but it looks like recent changes may actually be showing up a bug in the Windows Media Player 'IsPlaying()' function.. whereby it never reports back 'false' when the video has actually ended (and hence it sticks in a 'Finished' + 'Playing' state).

I would however expect if 'IsFinished' has been fired/detected manually, then 'Rewind()' + 'Play()' is called that the video would restart - similar to dragging the playhead back in the Media Player component once it's finished, which works for me here.

I'll keep you posted once I know more.

Cheers,

I've looked further into this and it seemed to stem from an old bug (https://github.com/RenderHeads/UnityPlugin-AVProVideo/issues/263) whereby MF and DS 'IsPlaying()' functionality didn't match WinRT/other platforms, now exacerbated by more recent changes.

I've now tried to bring MF and DS into line with the others, so:

• DS ended event is now tracked (previously relied on time > duration)
• DS/MF 'IsPlaying()' (/'IsPaused()') now checks actual video playback state
• When DS/MF end playback, if seeking is performed then they default to a paused state
• When DS/MF end playback, if play is called without any seeking then they'll auto-rewind and play
• If DS/MF is set to looping then they internally avoid calling play as they're already in that state
• DS/MF playback states/tracking more homogenised

Hopefully this addresses both this issue and #263 - changes should be in the next build.
