AVPlayer View

Scripting Forums AppleScriptObjC and Xcode
#1

I’ve looked through the forums here and have found almost nothing in relation to AV Player views… found numerous posts on QTkit, but it seems QTkit has been deprecated. All I am looking to do is automatically play a video within a window. Nothing fancy, and I don’t even need play/pause/stop/etc. controls. I do need the video to loop however. I’ve looked through some of the Apple documentation on AVPlayer but nothing’s working for me. Am I even headed in the right direction? Thanks!



property avPlayerView : missing value -- connected to AV Player View in IB

on applicationWillFinishLaunching_(aNotification)

        avPlayerView's assetWithURL_(path:to:movie)

end applicationWillFinishLaunching_

Hi,

either you create the view programmatically, set the frame and add to the window’s view
or you subclass NSView and add the methods described in the “Playing a Video File Using AVPlayerLayer” section.

PS: if you have the PlayerView subclass with the methods layerClass, player and setPlayer
write

set thePlayer to current application's AVPlayer's playerWithURL:videoURL
playerView's setPlayer:thePlayer
thePlayer's play()

Way over my head. Thanks for the response though! If I’m understanding correctly, there’s no ‘simple’ way to implement an AVPlayer View in the way a QTMovie View could’ve been done:


       tell current application's QTMovie to set {theMovie, theErr} to movieWithFile_error_(theMoviePath, reference)
       tell movieView
           setMovie_(theMovie)
           play_(me)
       end tell

EDIT:

Nevermind. Got it working with your snippet of code Stefan. Thank you!! Here’s what works for me:



script AppDelegate
	
    property parent : class "NSObject"
    
    property moviePlayer : missing value
    property playerView : missing value
	
    on applicationWillFinishLaunching_(aNotification)

        set videoURL to "file://path/to/movie"
        set videoURL to current application's class "NSURL"'s URLWithString_(videoURL)
    
        set moviePlayer to current application's AVPlayer's playerWithURL:videoURL
        playerView's setPlayer:moviePlayer
        moviePlayer's play()

    end applicationWillFinishLaunching_
	
end script

As there is no explicit video view object in Interface Builder for AVFoundation, no.

But it’s not too hard to create the subclass in Objective-C as described in the documentation and control the player with AppleScriptObjC

Hmm. Maybe I’m misunderstanding, but I got this working by dragging an AV Player View object (from the object library) into my window in IB, and then linking that as a referencing outlet to the playerView variable found in the code in my previous post.

Well there didn’t used to be one, but there is now…

#7

Usually I’m a late adopter :wink:

#8

Now where’s the fun in that? :lol:

A bit late, but here goes.

AVPlayers and AVAssets need to be inserted into an AVPlayer layer. The process is almost the same as a CALayer and a NSView ( contentView() , setWantsLayer_(true) , setFrame_(the frame size and location) , etc.

You refer to the layers and sublayers the same as any Core Animation Layer as well as any animated properties ( opacity, size , position etc. )

The difficult part is getting used to doing EVERY aspect of AVFoundation programatically. The upside is you will have a better understanding of NSView’s , Core Animation , NSWindows and a few other common classes that you would need to use in a project.

PS If you plan on using time functions, 99% are not accessible via ASOBJ. You will have to add a cocoa class ( many previous posts and examples )

After putting this on hold for a while, I finally got back around to it and got it working.

Originally I was using AVKit and an AV Player View in my project, but I needed to support 10.7/10.8, so AV Player View/AVKit was not an option, as it is only available in 10.9. So I had gone back to using QTKit, but it’s deprecated. What I ended up doing was subclassing NSView and setting everything up manually.

I needed the video to loop, so I created a NSTimer to handle running the following:



property playerView : missing value -- Linked to custom view in IB

        set videoPath to (current application's NSBundle's mainBundle()'s bundlePath()'s stringByAppendingPathComponent_("Contents/Resources/aMovie.mov")) as text
        
        set videoURL to current application's NSURL's fileURLWithPath_(videoPath)
        
        set AVAsset to current application's AVURLAsset's alloc()'s initWithURL_options_(videoURL, missing value, missing value)
        
        set AVPlayer to current application's AVPlayer's alloc()'s initWithURL_(videoURL)
        
        set AVPlayerLayer to current application's AVPlayerLayer's playerLayerWithPlayer_(AVPlayer)
        
        AVPlayerLayer's setFrame_(playerView's |bounds|())
        
        set AVPlayerItem to current application's AVPlayerItem's playerItemWithAsset_(AVAsset)
        
        AVPlayer's replaceCurrentItemWithPlayerItem_(AVPlayerItem)
        
        playerView's setWantsLayer_(true)
        
        AVPlayerLayer's setHidden_(false)

        playerView's layer()'s addSublayer_(AVPlayerLayer)
        
        AVPlayer's play()

Thanks everyone for your help!
