Public TechTV video downloads get truncated on slower connections #732

uwsgi will cut off a download after X seconds (formerly 60, now 180).

The video is being downloaded via OVS to customize the filename as a slug of the video title. The video could be downloaded directly from Cloudfront instead, but all TechTV videos will have the same name (hd.mp4).

The quickest/easiest fix for this is to redirect to the cloudfront URL directly. However the name of the downloaded filename cannot be modified this way - for old TechTV videos it will always be hd.mp4, for newer public videos it will always be video.mp4. So people downloading multiple videos will end up with hd.mp4, hd(1).mp4, hd(2).mp4, etc and will have to rename the files themselves if they want to.

If generic filenames are not acceptable, other possible alternatives are:

renaming all the existing public video s3 files used for downloading to a slug based on the current title, updating the database with those new filenames, and doing the same for any new public videos.
An approach used on a project I worked on years ago, with gunicorn and nginx, but for large uploads, was to have a separate gunicorn instance for the upload URLs, with a much longer timeout. nginx was configured to use that gunicorn instance for the upload URL's.
