Ultrawidify — aspect ratio fixer for youtube and netflix

TL;DR

If you own an ultrawide monitor, you have probably noticed that sometimes videos aren't encoded properly — they feature black bars on all four sides. This could happen because someone was incompetent (note: as far as youtube is concerned, improperly rendered videos might be due to youtube's implementation of certain new features). The extension kinda fixes that by doing this:

Works on Youtube and Netflix. Available for Firefox (v1.2.1) and Chrome (v1.2.1).

The long version

The technology has been here for a while, but plenty of people don't know how to properly encode a video (despite the fact youtube has an article that explains aspect ratios). Plenty of people surprisingly includes major Holywood studios, such as Marvel, Disney, Dreamworks, Warner Brothers, Sony, et cetera. You'd think that this is the one thing Holywood studios and people who make music videos for a living would know how to do right, but they don't. This extension is here to fix that.

Features

• Fit video to width/height
• Force specific aspect ratio
• Attempts to automatically detect aspect ratio
• Rebindable shortcuts

User interface

There's no longer any user interface lol. Only keybinds.

Default keyboard shortcuts

w - fit to width
e - fit to height
r - reset

a - attempt to automatically determine the aspect ratio (netflix only)

s - force 21:9
d - force 16:9
x - force 16:10
c - force 4:3

About aspect ratio autodetection

This is not available in AMO/Chrome version.

Aspect ratio autodetection is achieved by performing some black magic every 30-something milliseconds. This currently can't be turned off by default. If this extension makes video sites lag too much, open an issue and include your hardware and OS — this is important for me to know in order to better optimize autodetection..

Manually triggering aspect ratio change will suspend automatic aspect ratio detection for until the page is refreshed, although it'll maybe unsuspend itself when video is changed. I don't know for certain.

Plans for the future

TODO: add stuff for 2.0

• Adding custom keybinds (done at lastest)
• Adding a proper settings page (done at last)
• Adding buttons for actions in youtube's player (kinda done)
• Adding an option to force specific aspect ratio (now it's "good enough")
• Port to Chrome
• Have extension remember the last setting when switching between fullscreen and not fullscreen. (kinda done)
• Have an option to remember last selected aspect ratio.
• Option to hide UI
• Netflix support (done)

Changelog

###v2.0a1 (git/current version)

The extension is being rewritten almost ground-up, around automatic aspect ratio detection. By default, this extension now only works in fullscreen, but due to some simplification it should work on most sites. As direct result of this simplification:

• The UI is completely gone
• Ability to add custom sites has been scrapped (might get implemented later on if some sites are a bit more problematic
• Extension broken up between smaller files, this time the proper way
• Added "the impossible aspect ratio autodetection"
• Zoom/unzoom options are gone
• Can't customize keybinds yet

###v1.3a1 (git/current version)

• Adding ability to add custom sites (in progress)
• Most of the extension is being completely rewritten to accomodate that feature, which means there's a serious regression with Netflix support (no netflix at the moment)
• I'm also trying to break the 1500 line behemoth into smaller files.

###v1.2.1 (AMO + Chrome)

• Fixed the bugs which caused aspect ratio to not be calculated properly.
• Introduced further changes that allow me to not keep two separate version for Firefox and Chrome.

###v1.2.0

• Auto-aspect ratio detection on netflix
• initial port to Chrome

###v1.1.1

• Fixed zooming issue on netflix
• Ultrawidify shortcuts > youtube/netflix shortcuts
• Fixed 'settings' page
• Fixed 'settings' (wrench button) popup on youtube (it was broken by one of the previous updates)

###v1.1.0

• Introduced Netflix support.

As Netflix relies on extension re-initializing at least the UI a lot, the optimization introduced in 1.0.2 was reversed (as waiting 2 seconds for the UI to appear is just too much).

Furthermore, triggering UI re-initialisation on onUpdated events turned out to not be the proper way to go: immediately after the extension is initialized, onUpdated gets triggered even more often than your average Buzzfeed writer/reader. But change the episode on Netflix and suddenly, onUpdated gets barely triggered at all — which means that more often than not, the UI extension injects into the page wasn't visible. (the fuck, really)

This is why Netflix uses another function that manually checks whether the player bar is present. Ideally that check happens every tenth of a second, but Firefox may be limiting that to one per second.

###v1.0.2

The 'extension sometimes not working' bug was fixed (by having extension try to setup every time a page got updated), but the fix had some problems. Namely, the extension would re-initiate (complete with re-adding the entire UI) itself very very often.

This could be a problem, so it was fixed. Extension is notified of updates only every ~2 seconds (which absorbs most of the "page was updated" events on page load) and doesn't attempt to reload the UI if the UI was already loaded. (Unless debugmsg is set to true. It's generally not, but any commits to this repo could potentially still have it enabled).

###v1.0.1

Fixed the bug where sometimes the extension would fail to work. (example: you opened youtube's search page in a brand new tab. You then opened a video from the search results (not in a new tab). Extension wouldn't work at all in videos opened in that manner).

###v1.0.0

• Is pretty much rc1, except slightly different background image.

###v1.0-rc1

• Settings page is added and mostly working.

###v0.9.9.6

• The issue with buttons not fitting in the control bar was resolved.

###v0.9.9.5

• Played with settings and localstorage a bit, but no clear implementation yet.
• Fixed some bugs caused by event propagation.
• All buttons in the player's control bar are now also in the settings popup.
• Had to scrap settings page in its current form
• TODO: sometimes not all buttons can fit in the control bar. Such occurences should be detected.

###v0.9.9.1

• Keybinds a and w now work.
• Some changes under the bonnet, mostly regarding the way keypresses are handled.
• 'Settings' page is ~15% done.

###v0.9.9

• The aspect ratio thingy is now also in GUI
• Fixed code for forcing aspect ratio. At least I think it's fixed now.

###v0.9.8

• Added GUI/buttons on the player.
• Script now only loads on youtube pages (iframes included) (before, this script would run on any page)

###v0.9.7

• No new features added. Version number got incremented due to an attempt at autoupdating (which got foiled due to lack of HTTPS)

###v0.9.6

• Added experimental feature that tries to force an aspect ratio

###v0.9.1

• First version on GitHub (and on AMO) with basic features (zoom, fit to width, fit to height)
