Feature description

Many features don't work on downloaded files, and there are several bugs already open for individual features (enqueue #9829, mark as watched #9334, already downloaded #7360), but the real problem is that downloaded files are considered a separate case with its own features that are independent from the rest of NewPipe.

Also, when playing a downloaded file, it stops playing if you switch to a different app, one can't play the audio only, etc.

If downloaded files were considered a cache (which obviously requires a lot of work), then all the feature would not have to be treated as a special case, with a different bug for each of them, and new features would take this case into account.

Why do you want this feature?

Before losing data connectivity, I want to download a bunch of videos, and then continue using NewPipe offline, with all the features still working (going to a channel, selecting a video to play, switching to another app, etc), as all the information NewPipe needs is available locally.

The location for this should probably be /Android/media/org.schabi.newpipe/, like Whatsapp does for its files. If the user messes around with this and gets errors in the app, that's their own fault.

Maybe there could be a dialog upon tapping Download to choose between 2 options:

• "Download for offline play (This will download the file to the app's internal folder for playback within Newpipe)"
• "Download to permanent storage (This will download the file to an external folder for playback by other media players)"

This option in settings could be shown in a more simpler way. Enable Local Player in App with a sub-note Downloaded files will be played directly on Newpipe app but become not possible to be played on other apps

There could be two checkboxes as well: Videos and Audios. Some users may have only video or only audio player app installed on their phone. Or, one of their used apps don't offer the function available on Newpipe app. These checkboxes will be helpful for them.

This would be wonderful. I currently use a podcast app to play downloaded videos. This is less than ideal for several reasons:

• The obvious hassle
• Having to search the vid on NewPipe again, once done, so I can manually mark it as played. (As someone who consumes many short vids throughout the day [especially music], the played visual indicator is really important to me.)
• Lack of metadata. Sometimes this is really needed, i.e. timestamps. It would be amazing to download the top X comments, as a lot of times that's where timestamps occur, too.

Please see this as mere brainstorming...I'm quite aware this all gets really tricky.

Enable Local Player in App

That removes from the user the ability to choose where individual downloads go. I would understand having a checkbox like "Don't ask me again" for the Download alternatives dialog, but tightly coupling local playability with downloading to a specific location seems restrictive.

Another alternative is two completely separate buttons. The existing Download button stays as it is, and an additional "Save/Cache/Mark for offline playback"/"Play offline" can be added. I would suggest replacing the "Add to playlist" button with this one instead.

@foxjaw Instead of making multiple comments if you have something to add, you can edit your existing comment as many times as you like.

This is good but I'd want to be able to download to open with VLC for example. Maybe as an option which is off by default.

I'd advocate for two separate buttons:

1. "Available offline" or "Download". This one would work similar to the one in the YT app (and many other vide streaming apps) making the whole video available offline, including the info page.
2. "Save to storage" which puts a media file into the storage. If the video is available offline, it'd just show the file location dialog and copy/mux the cached video, if not, something similar to the download dialog would be shown; bypassing the offline cache.

This way, offline videos could also be put into the app's private storage's cache/ directory. They do not need to be user-accessible. Though clearing the app's cache would then also clear these offline videos which might not be desirable.

Though clearing the app's cache would then also clear these offline videos which might not be desirable.

That's a tricky one. One straightforward answer to this is that we simply don't use the regular cache folder, but another one that persists across cache-clearing operations. This folder would only be deleted if the user specifically takes that action.

However, that means offline videos would start filling up the App Data instead of Cache metric. If anything goes wrong (as it often does with filesystem operations), then the only way to get rid of all that potential junk is to clear the app data. Very non-ideal.

I don't know if it's possible, but maybe the offline video folder could remain inside the regular cache folder, and using the cache-clearing operation from within the app would prevent that folder from being emptied. Or maybe show a dialog asking if the user wants to delete cached videos as well.

This would also mean that clearing cache from the OS App Info menu would remove the entire cache including videos, but we could explain that in the app settings, and maybe in our FAQ as well.
