Could not calculate the thumbnail size.

[alfredolucomav]

Hello There,

I'm trying to load thumbnails from my video into trim view. But I have the following error: Could not calculate the thumbnail size.

This is my video's location: file:///private/var/mobile/Containers/Data/PluginKitPlugin/D7ABED4E-C54A-4948-B7D3-5587AE62358D/tmp/trim.CCA9A520-F11E-4BA6-A3A8-B15AA9E05CAC.MOV

What could be happening?

Best Regards

I had the same problem. You may be setting your trimmerView.asset before the frame is created for the trimmerView. If you want the thumbnail images to show up on the parent view controller when the parent view controller is presented then call trimmerView.asset = asset in override func viewDidAppear(_ animated: Bool)

Note: I did not have to convert file to m4v format.

I'm facing same issue.
First i tried to load video from bundle and created Asset from bundle URL.

`guard let bundlePath = Bundle.main.path(forResource: "Full_Video_Sample", ofType:"mp4"), let url = URL(string: bundlePath) else {
print("Can not find Full_Video_Samplem4v")
return
}
currentAsset = AVAsset(url: url)

trimmerView?.asset = currentAsset
trimmerView?.delegate = self
addVideoPlayer(with: currentAsset!, playerView: playerView)
trimmerView` is not nil as i created it dynamically in viewDidLoad.
