Using Swift5.3.2, iOS14.4.1, Xcode 12.4,
I am successfully running a VideoPlayer in SwiftUI.
I am calling the Player view with this code: VideoPlayer(player: AVPlayer(url: url))
.
The problem is that the video stops playing whenever a parent-View of the VideoPlayer updates (i.e. re-renders).
Since in SwiftUI I don't have any control over when such a re-render moment takes place, I don't know how to overcome this problem.
Any ideas ?
Here is the entire Code:
The VideoPlayer View is called as such:
struct MediaTabView: View {
@State private var url: URL
var body: some View {
// CALL TO VIDEOPLAYER IS HERE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
VideoPlayer(player: AVPlayer(url: url))
}
}
The MediaTabView is called as such:
import SwiftUI
struct PageViewiOS: View {
var body: some View {
ZStack {
Color.black
// CALL TO MEDIATABVIEW IS HERE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!d
MediaTabView(url: URL(string: "https://someurel.com"))
CloseButtonView()
}
}
}
The PageViewiOS View is called as such:
struct MainView: View {
@EnvironmentObject var someState: AppStateService
var body: some View {
NavigationView {
Group {
if someState = .stateOne {
// CALL TO PAGEVIEWIOS IS HERE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
PageViewiOS()
} else {
Text("hello")
}
}
}
}
}
This is in response to our comment thread on the other answer:
class PlayerViewModel: ObservableObject {
@Published var avPlayer: AVPlayer?
func loadFromUrl(url: URL) {
avPlayer = AVPlayer(url: url)
}
}
struct CustomPlayerView: View {
var url : URL
@StateObject private var playerViewModel = PlayerViewModel()
var body: some View {
ZStack {
if let avPlayer = playerViewModel.avPlayer {
VideoPlayer(player: avPlayer)
}
}.onAppear {
playerViewModel.loadFromUrl(url: url)
}
}
}
I'm not sure that this is definitively better, so it's worth testing. But, it does control when AVPlayer
gets created and avoids re-creating PlayerViewModel
on every render of the parent as well.
