Hi,
We have fragmented movie data that comes through WebSecureSocket (wss://). We are writing that into a temp.mp4 and simultaneously playing the fragments that got written into the file. So, we used AVFragmentedAsset and AVFragmentedAssetMinder for this. It works as expected in the simulator. But in the device, it doesn't update the duration of the asset and doesn't post .AVAssetDurationDidChange notification. Not sure what could be the issue. Already spent 2 days figuring out this but no luck. Can someone help me on this please,
This is the code.
// WSS listener
func onDataReceived(data:Data) {
tempMovieFile.write(data)
if !startedPlay {
// called only at the begining
startedPlay = true
DispatchQueue.global().async {
sleep(2)
streamDelegate?.didReceivedInitialData()
}
}
}
And
protocol StreamDataDelegate {
func didReceiveInitialData();
}
class PlayerController: StreamDataDelegate {
static let ASSET_MINDER = AVFragmentedAssetMinder()
let player = AVPlayer()
var fragmentedAsset:AVFragmentedAsset? = nil
init(){
NotificationCenter.default.addObserver(self, selector: #selector(onVideoUpdate), name: .AVAssetDurationDidChange, object: nil)
}
func didReceiveInitialData() {
// URL --> same file where movie data is currently being written
self.fragmentedAsset = AVFragmentedAsset(url: getTemporaryMovieFile()!)
self.fragmentedAsset?.loadValuesAsynchronously(forKeys: ["duration", "containsFragments", "canContainFragments"]) {
PlayerController.ASSET_MINDER.mindingInterval = 1
PlayerController.ASSET_MINDER.addFragmentedAsset(self.fragmentedAsset!)
self.player.replaceCurrentItem(with: AVPlayerItem(asset: self.fragmentedAsset!))
self.player.play()
}
}
@objc
func onVideoUpdate() {
// This is not called in device.. but in simulator it works as expected
}
}
