Therefore, it should be publishable 8 | to the chrome/ff webstores without any copyright issues etc. 9 | 10 | It remains to be seen how robust my regexes will be to playercore updates. 11 | 12 | ## Current features: 13 | 14 | - Enable Ctrl+Shift+Alt+S bitrate selection window. 15 | 16 | - 1080p video. 17 | 18 | - Disable VP9 profiles. 19 | 20 | - Enable 5.1 audio profile. 21 | 22 | - Auto-select stream with max available bitrate. 23 | 24 | ## Undocumented Keyboard Shortcuts: 25 | 26 | Netflix has a bunch of undocumented keyboard shortcuts, that do useful things. This list may be incomplete. 27 | 28 | - Ctrl+Shift+Alt+B - Bitrate selection menu (re-enabled by this project) (NOTE: This used to be S, not B!) 29 | 30 | - Ctrl+Shift+Alt+D - Debug overlay - displays lots of useful info and stats, including current resolution and bitrate. 31 | 32 | - Ctrl+Shift+Alt+T - Upload custom subtitle file, in DFXP/TTML format. 33 | 34 | - Ctrl+Shift+Alt+L - Log viewer. 35 | 36 | ## TODO: 37 | 38 | - Add settings UI (right now, you have to edit the source...) 39 | 40 | - Add comments detailing where I stole the code from... 41 | 42 | ## Credits: 43 | 44 | This codebase is cobbled together with bits and pieces from [truedread/netflix-1080p](https://github.com/truedread/netflix-1080p) and its various forks.
