@frankL the problem is that to can use update method, you have to use a subclass of ui.View, thus, replace all your play_action function by

class MyView(ui.View):
	def __init__(self, *args, **kwargs):
		global found_row
		ui.View.__init__(self, *args, **kwargs)
		n = nsurl(found_row[5])
		u=ObjCClass('AVURLAsset'). alloc().initWithURL_options_(n,None)
		i=AVPlayerItem.playerItemWithAsset_(u)
		p=AVPlayer.playerWithPlayerItem_(i)
		videolayer=AVPlayerLayer. playerLayerWithPlayer_(p)
		self.p = p
		self.i = i
		
		self.background_color = 'white'
		
		V=ObjCInstance(self)
		videolayer.frame=V.bounds()
		V.layer().addSublayer_(videolayer)

		self.update_interval = 0		
		
		self.left_button_items = (((ui.ButtonItem(title='  ', action= self.add_spaces))),(ui.ButtonItem(title='\u23F8',action=self.pause_video_action)), ((ui.ButtonItem(title='  ', action= self.add_spaces))),((ui.ButtonItem(title='\u25B6', action= self.play_video_action))), ((ui.ButtonItem(title='  ', action= self.add_spaces))),((ui.ButtonItem(title='\u23F9', action= self.stop_action))))
				
		self.slider=ui.Slider(frame=(0,0,self.width,110), background_color = 'lightblue')
		self.slider.action=self.slider_action
		self.slider.bring_to_front()
		self.add_subview(self.slider)
		
	def update(self):
		duration=self.i.duration()
		if duration.b == 0:
			return
		self.duration_sec=duration.a/duration.b
		s = self.p.currentTime().a/self.p.currentTime().b
		self.slider.value = s/self.duration_sec
		
	def play_video_action(self,sender):
		self.p.play()
		return
	#
	def pause_video_action(self,sender):
		self.p.pause()
		return
	#
	def stop_action(self,sender):
		self.p.pause()
		self.seek(0)
		self.slider.value = 0
		return
	#
	def add_spaces(self,sender):
		print('space')
		return

	def slider_action(self, sender):
		self.seek(sender.value*self.duration_sec)
		
	@on_main_thread
	def seek(self,t):
		T=c.CMTimeMakeWithSeconds(t,1)
		self.p.seekToTime_(T,argtypes=[CMTime],restype=None)
		
def play_action(sender):
	global p

	v=MyView(frame=(0,0,500,500))
	v.present('sheet')

	v.p.play()
	v.update_interval = 1/60

cvp,
I replaced the play_action function with your code and I get an error "name '@on_main_thread' is not defined". I'm relatively new to python and haven't tried to create and use "class" so there must be something else I need to add somewhere. What should I do? Thanks

@frankL sure that this line is still in the imports...

from objc_util import *

cvp

@frankL I'll be away for 2 hours, sorry. Anyway, if problem still occurs, you can post your code again, included in two lines with ``` (you can use the </> button to generate them).

cvp

@frankL or if you prefer, I post your full script modified with my little part.

frankL

Apparently I had the 'from objc_util import *' after the class MyView(ui.View):
Once I move it up everything works perfectly. I can't thank you enough.
I retired a few years ago and just started learning Python last summer and Pythonista late last fall so I've got a lot to learn and I really appreciate all of your help and the help from everyone on the omz:forum.

@frankL 👍

Thank you for your help. My video player script is now working very well. I still have one other hurdle that I haven’t figured out how to solve and can use some more help. I have created a csv file to hold the url and some other parameters for each video. I use the parameters in my video player script to find the one I want and play it. The way I got the url for each video was very manual and I would like to eliminate the manual step. I used the video picker from the minimal player to select the video from my iphone and print the AVURLAsset to the console which looks like this:

<AVURLAsset: 0x280d73c00, URL = assets-library://asset/asset.mp4? id=40295592-62D9-4521-9DFF-74A5683BF5EB&ext=mp4>

I then click on it in the console and copy it and then paste:

assets-library://asset/asset.mp4? id=40295592-62D9-4521-9DFF-74A5683BF5EB&ext=mp4

to another script as part of a list with the other parameters like this:

Dance = 'Tango'
Instructor = 'Lucy'
description = 'Tango 001-Ronde to swivels'
label = 'Ronde to swivels'
n = nsurl(assets-library://asset/asset.mp4? id=40295592-62D9-4521-9DFF-74A5683BF5EB&ext=mp4')
row = (Dance, Instructor, description, label, n)

to create a row. In order to make this work, I have to paste the url into the n=nsurl(‘ url-goes-here ’) that includes the inner single quote marks.
Once I had several rows, I ran a script to write the csv file which I use as my database for videos.
So back to my question, is there a way to grab the AVURLAsset from the video picker
u=pick_asset()

and somehow extract the url from u, and create the row to append to the csv file?

cvp

@frankL only, when you pick your asset

def pick_asset():
	assets = photos.get_assets(media_type='video')
	asset = photos.pick_asset(assets)
	phasset=ObjCInstance(asset)
	url_str = str(phasset.ALAssetURL())

You store this url_str in your csv

And when you use it

	url = nsurl(url_str)
	asseturl=ObjCClass('AVURLAsset').alloc().initWithURL_options_(phasset.ALAssetURL(),None)

Thank you.
