how to get last video on iphone?
-
-
The player works perfectly. If I wanted to pick a video and get it's url and save that for later, how would I pass that url to the player directly and not from the pick_asset call?
-
@frankL in the script, you can print(u) to get an url like assets-library://asset/asset.MOV?id=C03ABFB4-08F3-4A00-B626-BB9A01B293B2&ext=MOV
So, if you save this string in a file, you can reuse with these lines
url = nsurl('assets-library://asset/asset.MOV?id=C03ABFB4-08F3-4A00-B626-BB9A01B293B2&ext=MOV') u=ObjCClass('AVURLAsset').alloc().initWithURL_options_(url,None) i=AVPlayerItem.playerItemWithAsset_(u) p=AVPlayer.playerWithPlayerItem_(i) videolayer=AVPlayerLayer.playerLayerWithPlayer_(p)
-
I printed the url, substituted it as you suggested, but after:
url = nsurl('assets-library://asset/asset.MOV?id=7C43F2B6-68DB-4314-80A7-34C6F92E8C8A&ext=MOV')
C03ABFB4-08F3-4A00-B626-BB9A01B293B2&ext=MOV')
u=ObjCClass('AVURLAsset').alloc().initWithURL_options_(url,None)print(u) returns None
I must still be missing something. -
@frankL ok, sorry, print(u) is erroneous, I wanted to say print(url), what you did.
But now you have the url as a string, you can save it where you want and read it later to only
Display via some script lines of my post, without passing via pick -
@frankL this script only plays a video. Up to you to save the url in a file in the initial pick script and to read it and play in this script
from objc_util import * AVPlayerItem=ObjCClass('AVPlayerItem') AVPlayer=ObjCClass('AVPlayer') AVPlayerLayer=ObjCClass('AVPlayerLayer') url = nsurl('assets-library://asset/asset.MOV?id=C03ABFB4-08F3-4A00-B626-BB9A01B293B2&ext=MOV') u=ObjCClass('AVURLAsset').alloc().initWithURL_options_(url,None) i=AVPlayerItem.playerItemWithAsset_(u) p=AVPlayer.playerWithPlayerItem_(i) videolayer=AVPlayerLayer.playerLayerWithPlayer_(p) import ui v=ui.View(frame=(0,0,500,500)) V=ObjCInstance(v) videolayer.frame=V.bounds() V.layer().addSublayer_(videolayer) v.present('sheet') p.play()
-
That works perfectly, thank you.
Is there some documentation on video players and objc that you could point me to so that I can get a better understanding of how this all works? -
-
Thank you. I had only been looking at Pythonista 3 documentation and just recently came across the photos module. Photos doesn't appear to support much in the way of videos.
I appreciate all of your help. -
Is there a simple way to add controls to the player such as pause, play, etc.?
-
@frankL try this
from objc_util import * AVPlayerItem=ObjCClass('AVPlayerItem') AVPlayer=ObjCClass('AVPlayer') AVPlayerLayer=ObjCClass('AVPlayerLayer') url = nsurl('assets-library://asset/asset.MOV?id=71F89028-7FA0-4C53-B6AD-6659BC8458D8&ext=MOV') u=ObjCClass('AVURLAsset').alloc().initWithURL_options_(url,None) i=AVPlayerItem.playerItemWithAsset_(u) p=AVPlayer.playerWithPlayerItem_(i) videolayer=AVPlayerLayer.playerLayerWithPlayer_(p) import ui v=ui.View(frame=(0,0,500,500)) V=ObjCInstance(v) videolayer.frame=V.bounds() V.layer().addSublayer_(videolayer) v.present('sheet') p.play() bplay = ui.ButtonItem() bplay.title = 'play' def b_play_action(sender): p.play() bplay.action = b_play_action bpause = ui.ButtonItem() bpause.title = 'pause' def b_pause_action(sender): p.pause() bpause.action = b_pause_action v.right_button_items = (bplay, bpause)
-
@frankL you can even find an example of a slider in the minimal à player Of @JonB
-
Thank you. All that is running correctly now. How can I update the slider to indicate the elapsed time status of the video? The Apple documentation is very difficult to understand.

@frankL try until
v.update_interval = 1/60
-
@frankL Is it what you wanted?
-
I see that your code works but I'm trying to implement it in a subview and I can't figure out how to use the v.update_interval method.
-
To clarify, I have a button in the main view that plays a video that the user selects from the main view. The button action instantiates a subview that runs the video and presents the slider, play, pause and stop buttons. The slider works to move the video playback manually but otherwise the slider doesn't display the elapsed time of the video. Any insight you can give me would be appreciated.

update_interval is not a method but an attribute setting thé interval in seconds between 2 calls to the update méthod in a subclassed view.

It would be easier to help if you post your script.
