[FR] - Support bulk/playlist download

[untotren]

when I put playlist right now, it generates many links. It would be nice to bulk download, perhaps even as a .zip.

@untotren re: zip: currently the server never touches the actual stream/video/audio data, it just passes the actual stream URLs to your browser so that the user can download them. Zipping the audio/video data would require that the server downloads the actual data, before zipping it, and then uploading it to the user. This doubles the required bandwidth (most a/v data is already compressed and zipping only results in wasted CPU cycles) and is very far from how alltube currently works.

Re: bulk download: As far as I know it is not possible to download multiple files from a single HTML link. Your best bet would be using a bulk download manager or browser addon such as DownThemAll

Another possible solution would be assigning a class=downloadlink to all download links, and adding JavaScript that would simulate clicking on all those links: https://apple.stackexchange.com/questions/151742/download-all-linked-files-at-once-from-a-website-in-safari/176471#176471. Note that this 1. would require JavaScript 2. Could generate a large number of "Save as..." dialogs when the playlist has many items.

I'm currently trying different approaches for this. This is not so far from options we already provide (MP3 conversion, remux) but it can potentially use a lot of resources so we probably won't enable it by default.

JavaScript becomes a nightmare with playlists that have a lot of videos so I'm looking for a server side solution.
We might use a library like ArchiveStream-php to stream tar data to the browser.

I tried two different libraries that could do this but they both have issues that are blocking me:

• Build an archive from a stream barracudanetworks/ArchiveStream-php#42
• Get a stream without printing it immediately Grandt/PHPZip#45

[Rudloff]

I added experimental support for this on the develop branch (d3c6825).
You need to have stream: true in your config.yml file for it to work.
I have only tested it with Youtube playlists.

Closing as the basic functionnality is there.
Please feel free to open new issues for bugs or enhancements.
