How videos add to the camera roll
I know how images add to the camera roll,using
However, I don’t know how videos add to it.
I cannot search anymore.Please teach me!
@cvp : Thank you very much for quick response and useful information. I will try the code on my plan and get back to you.
@cvp I tried the code. I can add the video to specified album. However, the code creates the album every time when adding another video to the album with same name (many 'my_album' are created); can not add the video to existing album. Any information or alternative way ?
@beans sorry for that, I have only tested once. I'll try in the afternoon Brussels time
@beans that should be ok, I hope

@cvp Thank you very much. The code works as expected. Very helpful. Additionally I found another issue through testing the code: the file should be accessible as internal file, the file is only stored in iCloud Drive (not imported to the device as accessible) can not be added. I assume this is reasonable but if any way to start importing from iCloud Drive to the device by the code it will be further helpful. Any ideas ? Sorry for repeated asking.
the file is only stored in iCloud Drive
In which folder? Try to open it as "external folder" in Pythonista files browser
@beans Once you have defined your iCloud Drive folder as external folder in Pythonista, you can get a file with
url = nsurl('/private/var/mobile/Library/Mobile Documents/com~apple~CloudDocs/MyFolder/mov_bbb.mp4')
@cvp I opened that iCloud folder from EXTERNAL FILES. The folder is shown in EXTERNAL FILES. The files existed in the folder are accessible as '/private/var...', however, the files newly added to that folder are not shown in the folder of EXTERNAL FILES and are not accessible as '/private/var...' The newly added files can be shown using os.listdir('/private/var...'). The file names are shown as '.filename.icloud' (they are not shown in the folder of EXTERNAL FILES). I assume the files are not imported to the device or not synced with EXTERNAL FILES and would like to know if any way to import the files by the code.
@beans it is a known problem: a file not yet locally downloaded is not accessible 😢
If you first download it in the Files app, you should be able to access it.
I think there are some topics in this forum about this problem.
Sorry for you
@cvp Thank you for the information. Anyway, the code is very useful.
