Video as a background

@RocketBlaster05 No, you can still do it without a webview. Here’s one I made using my custom AVPlayer class

[ts]

The first code is saved in a file called AVPlayer.py

[RocketBlaster05]

@ts Does the first program require a URL to like a youtube video?

[RocketBlaster05]

def get_playerItem(url):
return objc_util.ObjCClass("AVPlayerItem").playerItemWithURL_(objc_util.nsurl(url))

And if so Is this line where I put the URL?

[ts]

It’s optional, AVPlayer() accepts None or a URL, but yes AVPlayer(url)

[ts]

You import AVPlayer from a different file as seen in the second code. That function gets called automatically when you either create a new AVPlayer() or call the replace_item() of the AVPlayer()

[RocketBlaster05]

@ts I Used a YouTube Link in order to test it but it says I have invalid syntax at the question mark in the link (i.e. youtube.com/watch?...) Any Ideas why this is happening? Thanks

[ts]

You are going to need the youtube_dl module to get the direct link (not a webpage). If you had local files or a direct link to the media item (video / audio) this would work (pass ‘audio’ as the second argument for AVPlayer() to work with an audio player), otherwise you may have to look into the webview route unless you figure out how to install youtube_dl

[cvp]

I think if you have downloaded your video in Pythonista files, you could use url like

file:///private/var/mobile/Containers/Shared/AppGroup/1B829014-77B3-4446-9B65-034BDDC46F49/Pythonista3/Documents/MesTests/mov_dog.mp4

[cvp]

This works

import os
import ui

v = ui.View()
v.frame = (0,0,400,400)
web = ui.WebView()
v.add_subview(web)
movie_path = '~/Documents/MesTests/mov_dog.mp4'
mov_url = 'file://' + os.path.expanduser(movie_path)
mov_url = mov_url.replace(' ','%20')
web.load_url(mov_url)
v.present('sheet')

[ts]

@cvp My introduction is haunting me...I didn’t mean what I said. I said “I made” and then “with the help”, you guys are really kind here and it looks like I just appeared snatching some code and claiming “I made” (I still edit that post to hopefully fix the way I wrote it). Also I’m not trying to ignore you or “be that new guy”, I just wanted to contribute back for all the support here (as a thank you). I guess I deserve that for my quick jump “No here’s my AVPlayer script though”, but instead I should have made my own post to share my code as thanks now I think about it...

Also feel free to correct my grammar / code, along with using my code :) I spent nearly if not over 3 years (on and off and many variants of it) updating @JonB take on his avplayer.py (thanks @JonB). I learned from that (originally borrowed his seek method otherwise figured out how it worked) and realized not long ago I don’t actually have to define a CMTime struct in order to seek. The longest and first feat was figuring out how to rotate the video lol...and thirdly obtaining a kCMTimeZero for better precision for seeking after figuring out how to get the seek to work... Also realized since the AVPlayerLooper doesn’t allow a swapTemplateItem method, I just use the standard AVPlayer which works as intended (after a replace item otherwise the AVPlayerLooper freaks out -> requires more replacing). I made the AVPlayer class so I can reuse it, make it better, but more importantly hook it up to work with playlists (once I figure out how to implement that feature). I have lots of ideas; mute audio, add video / audio objects, look into an audio normalizer to save your ears, loopCount, loopBy, and more

[cvp]

@ts Don't worry, you can't find worst grammar than mine and even my code is always quick and dirty (my signature 😁). In the forum, for me, if we can help somebody with some lines, it is good. The requester can always make the code better or easier for his personal use.
Welcome here in this marvelous forum, full of marvelous guys using this marvelous app developed by a marvelous super-héro.

[ts]

I entirely agree with your last statement, that is very true (still amazing to this day)

[ts]

@RocketBlaster05 Oh sorry, sometimes I do that. You can take out the .isfile() check in the replace_item() to allow links (I just realized my mistake) and take out the is_int function in the first script (I took out a method that used it but fix is_number() first since that’s the only thing using it). As well take out the “import os” since there is no more, a call to that module. Also that code (first script) can be saved however you want to name it, as well as the class name, but when you want to utilize it, the format is

from file_name import something

So in my case, the file_name is AVPlayer and I’m importing the class AVPlayer. Also if you run into issues, discuss it somewhere on this forum so I can improve it

The other thing I noticed was in the init(), I did

if type(arg) == str:

Instead of

if isinstance(arg, str):

(The difference as I looked it up when I first noticed it is isinstance accepts inheritance whereas type does not)

[ts]

@RocketBlaster05 If you still require the youtube_dl module, you can do it as suggested here or alternatively a small edit I did from his script years ago (in order to get it to work, also, let me know if this code should be removed from this post). Every other week or so, you can backup then download to keep it updated
