[GStreamer] Let playbin handle redirects for us when appropriate

[Philippe Normand]

Because in MediaPlayerPrivateGStreamer::loadNextLocation() the security-origin check fails.

[Philippe Normand]

Original url example: https://movietrailers.apple.com/movies/wb/shazam/shazam-trailer-2_480p.mov
Redirected url example: http://movietrailers.apple.com/movies/wb/shazam/shazam-trailer-2_h480p.mov

I suppose the origin check fails because the new url doesn't use https?

[Michael Catanzaro]

Yup, the different protocol means it's a totally different security origin with no permission to access the other. Security origin is <protocol, host, port> (except in Internet Explorer, where port is not considered).

[Thibault Saunier]

To me the issue is in the REDIRECT is incorrect, it should point to the `https` variant.

chrome or firefox are not able to play that stream either, for some reason Safari is.

I would just close the bug tbh.

[Philippe Normand]

Hi Eric,

Can you shed some light here, maybe?
Is this a server-side issue? Why is Safari not affected?

[Philippe Normand]

Trailers play fine in Chromium here.

[Thibault Saunier]

I proposed patches in GStreamer to allow a better handling of redirection in case of quicktime streams with no tracks so playbin can support it for us, see:

- https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/merge_requests/419/diffs
- https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/merge_requests/340

This makes thing simpler and cleaner for us, let's see how it goes there :-)
