Livestream support

[Zero3K]

It would be nice if it supported the playback of Livestreams. Right now I get a "No compatible source was found for this media" error message when trying to view one.

The main issue with this is that YouTube adds CORS headers on all assets, which functionally means you can't make XHR requests (which are required for viewing livestreams). There is already a feature in Invidious that allows you to get around this, but it's not been tested fully.

The feature should be added/enabled on the site so I can test it.

I misspoke: there are a couple of issues with that are still being fixed. Namely: how to properly generate a working manifest and serve the necessary assets. You can generate a manifest for the given video by asking /api/manifest/dash/id/:id. It will also probably be necessary to append ?local=true to swap the links in the manifest with those that have a corrected header. Currently it seems like only youtube-dl can use it. If you have youtube-dl installed you can run youtube-dl https://invidio.us/api/manifest/dash/id/:id?local=true.

There are still some issues that need to be worked out, but expect it to be added soon.

I wonder if it is possible to view the chat along with the livestream. If it is, please consider implementing it.

[Zero3K]

How much longer until they are supported?

[Zero3K]

So, is it possible to view the chat of a live stream or not?

Not currently, although I would recommend opening that as a new issue "Add live chat" or similar.
In addition, it seems pretty closely related to #68. Most of the value of live chat it seems to me would be in being able to respond to the video and others in real time, which requires a Google account.
