Download Movie

[sbarber2]

It would be nice if users could download movies.

How many times have I wanted to download a movie in the dev.planttracer.com instance so I could use it in my local instance? Many.

It's probably a use case that users in a course will want to share movies in the sense that they may want to do different tracking runs with different marker positions.

I strongly suspect this feature will want access control.

Quick take on what those access rules might be:

• A user may download any movie they have uploaded
• A user may download all published movies in courses in which they are registered
• A course admin may download any movie in that course
• A super admin may download any movie in the entire database

Yes, of course, users could manage their own movies files elsewhere and share them that way, but being able to download movies from the app is just going to be handy.

You can. Click 'play' and then right-click:

A fair point. So much for access control (if that was ever desired).

OK, that works, more or less.

I tried this in Chrome against dev.planttracer.com on the movie with id 5724. It downloaded the movie to a file named 5724-243a.mov

In MacOS Safari, the file is named get-movie-data with no extension.

In MacOS Firefox (131.0.3), pressing Play on the Movies page for this movie doesn't work, so that'll be a new Issue. (#608)

We can document this for users, as they won't all think of it on their own.

But I'd say given these results, if Download Movie is to be a positive feature of the webapp (rather than an artifact of the browser environment as it is now), then we have some work to do in order to make it both nice and friendly and a bit more user-proof.

We could certainly create a download link that just downloads the movie if you want that. It's about 5 min to change, just some HTML and JS.
