how to get last video on iphone?

[cvp]

@frankL said:

video = last_video.get_ui_image()

This line implies that you take only one image.
What do you want to do?
Copy a video from the camera roll to....?

[cvp]

@frankL this copies picked video to Pythonista local files

import photos
from objc_util import *
import time
import shutil
import os
	
videos = photos.get_assets(media_type='video')
assets = photos.pick_asset(assets=videos,multi=True)
#print(dir)

options=ObjCClass('PHVideoRequestOptions').new()
options.version=1	#PHVideoRequestOptionsVersionOriginal, use 0 for edited versions.
image_manager=ObjCClass('PHImageManager').defaultManager()

handled_assets=[]

def handleAsset(_obj,asset, audioMix, info):
	A=ObjCInstance(asset)
	'''I am just appending to handled_assets to process later'''
	handled_assets.append(A)
	'''
	# alternatively, handle inside handleAsset.  maybe need a threading.Lock here to ensure you are not sending storbinaries in parallel
	with open(str(A.resolvedURL().resourceSpecifier()),'rb') as fp:
		fro.storbinary(......)
	'''
	
handlerblock=ObjCBlock(handleAsset, argtypes=[c_void_p,]*4)

for A in assets:
	#these are PHAssets
	image_manager.requestAVAssetForVideo(A, 
						options=options, 
						resultHandler=handlerblock)
						
while len(handled_assets) < len(assets):
	'''wait for the asynchronous process to complete'''
	time.sleep(1)

for A in handled_assets:
	url = str(A.resolvedURL().resourceSpecifier())
	local = os.path.basename(url)
	print(url)
	shutil.copy(url,local)

Thank you. That allows me to find my videos, but how do I play them either in the console or otherwise?

[cvp]

@frankL try this @JonB ' s player

[frankL]

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?

[cvp]

@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)

[frankL]

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.

[cvp]

@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

[cvp]

@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()

[frankL]

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?

[cvp]

@frankL standard Apple doc contains all (and more) info needed, good luck

[frankL]

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.

[frankL]

Is there a simple way to add controls to the player such as pause, play, etc.?

[cvp]

@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)

[cvp]

@frankL you can even find an example of a slider in the minimal à player Of @JonB

[frankL]

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

[cvp]

@frankL Is it what you wanted?

[frankL]

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.
