Ensure background uploading is working

[n8fr8]

• ensure videos can upload when the user leaves the app, at least up to the 3 minutes mark
• ensure video upload resumes when the user returns to the app if the 3 minute mark expired
• ensure status of upload is tracked appropriately when upload completes in the background

Progress tracked in #127.

@tladesignz reopening since app stops once we navigate away/open diff app - background uploading should work

[tladesignz]

I guess you forgot?

There's no big background upload possibilities on iOS. Never have been, never will.

The only thing you can do is drop 1 (in words: one) file into the OS to tell it to upload it in the background.

• Doesn't work with metadata, since it needs to be a file stored on disk, which with metadata we never do, but generate on the fly.
• Doesn't work with all the folder check/creation we need to do to prepare the actual file upload.
• Doesn't work with Dropbox.
• Doesn't work with complicated authorization schemes.
• Doesn't work with chunked uploading, since each chunk is one file.
• Can't schedule another upload after the one, the system did for us, because we never get called back.

However, uploads shouldn't stop immediately after you leave the app. Save pleas with the OS to keep it alive in the background. This is usually granted for 3 minutes, as long as the battery is in a decent charge range. (AFAIU above 20% typically, resp. not in battery saving mode.)

If that doesn't work anymore, please open up a new issue and I will check that.

Additionally, we can think about providing a dedicated upload mode, like lots of other uploader apps do:

• Keep display active without interaction (like when watching videos).
• Tune down brightness as much as possible after some timeout, bring it back, when user touches screen.
• Leverage proximity sensor, which allows us to shut down screen completely by laying the device screen-down on a desk, but keeps the app in foreground.

=> Needs some UX design. The upload manager scene seems a natural candidate to extend.

@tladesignz I did not forget - can you implement a dedicated upload mode as you mentioned above? While it may not be fixable right now, this is an ongoing issue that we need to resolve somehow, someday, so we need to keep this open.

Can we please keep tracking this in #198 instead of constantly reopening 5 year old issues?

And please stop assigning me tasks, which are totally underspecified. Provide texts! Provide some UX ideas! (Can be text-only. But something I can work with.)
