[2.1.8] Hap with Custom MOV Parser seek from last frame to first frame causes playback to stop

[jeroenvandervelden]

Describe the issue
Custom MOV Parser, HAP file: When entering the last frame, seek to the first frame(s) > playback stops, no way to start again.

Your Setup (please complete the following information):

2021.1.16f1
AVPro Video version: 2.1.8
Operating system version: Windows 10
Device model: Razer Blade RTX 2070
Video specs (resolution, frame-rate, codec, file size): 1920x1080 or 3840x2160, 25fps or 50fps, HAP, HAP Alpha

To Reproduce

• Play HAP codec Video with MediaFoundation API & Custom MOV Parser
• In the Update of a behaviour, check for GetTimeFrames() >= getDurationFrames() - 1). If so, do a Seek (or SeekToFrame) to frame 0.

Playback stops and is not possible to re-start again.

When disabling the Custom MOV parser, it works like it should.

Hi,

Out of interest, why are you seeking to the first frame from the last instead of setting the video to loop? What is the reason for using the custom MOV parser if it works without it?

Have you tried a seek at another point in the video?

Would it be possible to send a reproducible case/your media over to unitysupport@renderheads.com?

[jeroenvandervelden]

Those are some valid questions ;)

• We expose a 'loop in' and 'loop out' point to our users. When users pick 'play loop' mode, the video should loop between set in and out point. Whether that point is at the end of the video or before. Our default is 0% & 100%.
• We use the custom MOV parser because some user videos can be HAP(a/r) at very high resolution, exceeding the limited Windows MOV parser bandwidth.
• Seek from/to some other points does work, trying to find the logic in there.

I will create a test project tomorrow if my schedule does allow me!

Demo project sent!

Thanks for the details and the project file.

@AndrewRH have added the project to s3, suspect this is a bug.

Doesn't necessarily stop after the first seek, but sometimes only after the 4th, for example.

[jeroenvandervelden]

Is there perhaps an estimation of when a solution would be available in a new release?

[kahnivore]

We'll try get it into our next release coming early next week.

Would be awesome, thanks!
