问题
Me and my team are stuck on an issue for a few days now.
We have AVPlayer which plays AVPlayerItem with a custom AVVideoComposition.
player.currentItem?.videoComposition = getUpdatedVideoComisition()
The user can decide if to remove or keep the composition. I'm trying to remove the composition by calling
player.currentItem?.videoComposition = nil
But in an unexpected way even when assigning nil to the videoComposition property, it's keep on playing with the same composition.
How can we remove the AVVideoComposition without switching AVPlayerItem?
Any help will be highly appreciated.
Best Regards,
Roi and the team
