The current project compiles and runs on both the simulator and device but just displays a full grey screen.

UIPanGestureRecognizer responds to gestures and I can see and play the VR.mp4 in xcode but still can't see the VP.mp4 video in the app.

I am trying to take action when the video finishes. To do this I subscribed to the AVPlayerItemDidPlayToEndTimeNotification notification. By doing this I noticed that this notification gets called repeatedly after the video finishes, multiple times a second.

I looked into the issue further by setting up KVO on the "rate" property of the player and noticed that after the videos finishes the rate values switches between 0 and 1 repeatedly, multiple times per second.

This explains why AVPlayerItemDidPlayToEndTimeNotification is getting calls so much but does not explain why the rate keeps toggling. The actual on screen video is frozen at the last frame and does not seen to be impacted.

The only thing that breaks this loop is calling videoSpriteKitNode!.pause(). Even this approach is not ideal because you still get a few AVPlayerItemDidPlayToEndTimeNotification notifications before you have a chance to call videoSpriteKitNode!.pause().

For mp4 files that have audio I can not get the audio to be included in the playback. The volume property for the underlying AVPlayer is 1.0 but there is still no audio.

Any suggestions?

Hi Aralekk,

I've discovered that with long videos, over 20 seconds, there is a major memory leak that causes the app to crash. I believe it is caused by the renderer function.

When reworking the view controller to non stereoscopic, using only left scene camera, there are no memory issues. I've tried debugging this, but have had no success. I was wondering if you would take a look at it possibly.

Thank you,

Micah

i'm toying with the play/pause feature where upon going from play to pause the motion tracking pauses as well. before going back from pause to play, the orientation of the phone could change. for example, i could resume watching turned 180 degrees from where i was before.

as a result, upon resuming the device orientation tracking will update the view to show me the content that is 180 degrees from the frame in which i paused.

my goal is to make it such that when i resume playback under my new orientation, i will be able to resume watching from the angle in which i left off and still have the device motion tracking update as i move around while the video is playing again.

i'm struggling to understand how i'd accomplish this as i'm not very experienced thinking in 3d graphics.

how would you offset/update the orientation/quaternion based on the previously paused orientation to solve this use case?

Its working with the base example and the main bundle stuff

but if i save the file in the documents directory the player is not playing the file FileExists on iphone

any ideas?

Hello,

there are huge memory leaks not caused by you developers directly but I think that its Apple's SpriteKit and AVKit.

Steps to reproduce are simple:

1. downloaded project
2. migrate to swift 3
3. build on actual device
4. play video, at the end of video seek with bar on the beginning and play again
5. do this couple times
6. in debug monitor in section with memory you can see that memory is growing all the time during playing
7. at the end app crash

Just spotted this – if you run the example, pause it for a while and rotating the device a few times will autoplay the video. Even this is at paused mode?

hi Aralekk, I found the device getting very hot when running this player(it once induce the system restart), so I analyze with xcode instruments GPU tool, and found: renderer utilization %: 70~82 tiler utilization %:70~86 texture count: 809 device utilization %: 74~89

maybe an issue? or is there any method to lower them? thanks a lot~
