What did you do?
when playing multiple tile (divide from one large video), sequential play button delay. I've add first loading stream, add setClockOffset = some value (ms) .

What did you expect to happen?
make sync with each tile.

What actually happened?
offset value to over 1000, it doesn't effects on MPD presentation.

When , What time , Where I call setClockOffset ? it makes effects.

Thanks.

Are you using multiple instances of shaka.Player to play this video?

The only method called setClockOffset is on PresentationTimeline, which shouldn't really be used by the app. You shouldn't call this method at all, it is called automatically during manifest loading. This is used to ensure the server and the app have the same clock times.

Are you talking about playing one MPD file that has multiple parts, or loading multiple MPD files?

@themodmaker yes multiple instances same time.
It is can be called in mpd is problem I think.
Is there runtime setting the pts timing ?

We don't really provide a cross-video synchronization mechanism. You'll probably need to do something in your app. Assuming the different streams are generated on the same server and have the same availabilityStartTime (i.e. they started at the same time), you could probably just set the video.currentTime for each video to the same time and they should be synchronized.

Alternatively you'll need to provide some offset from each stream to your app. For example, if you set video1.currentTime to 45, you may need to set video2.currentTime to 50. You would need to send this info to your app and handle it yourself. We don't provide a way to synchronize two videos. Remember that each video is an independent video stream from our perspective.
