FOSS extension that delays audio and video for synchronized playback

=== Privacy ===
Audio/Video Delay runs locally and does not collect any user data or analytics. It is fully open-source and can be audited at GitHub.

=== Limitations ===
- DRM-protected content can only have its audio delayed. The screen will appear black when attempting to delay DRM video.
- Subtitles are delayed only for videos on YouTube and the JW Player

=== Usage Guide ===
Ensure graphics acceleration is enabled in your browser settings. If you have multiple displays, set all to the same refresh rate or watch videos on the one with the highest.

-- Enabling/Disabling the Extension
Enable or disable the extension by pressing the bottom button in the GUI. The current on/off state is reflected here.

-- Changing Delay Modes Between Audio and Video
Video is delayed by default. Delay audio instead by clicking the yellow "Video" button at the top of the GUI. It will change to a red "Audio" button, and clicking it will return the delay mode back to video.

-- Changing the Delay Amount
Input the desired delay (in milliseconds) in the middle box of the GUI; no page refresh is required.

=== Support the Project ===
If this extension solves your audio issues, please consider sponsoring me at Ko-Fi. Even better (and free!), leave a review or star the GitHub repository. Many hours went into making the experience as seamless as possible, so any way of paying it forward is greatly appreciated! If you would like to contribute to the code, you are welcome to do so in the develop branch. If you encounter an issue, please open a GitHub Issue or mention it in a review. Thank you!

=== Privacy ===
Audio/Video Delay runs locally and does not collect any user data or analytics. It is fully open-source and can be freely reviewed at GitHub.

=== Usage Guide ===
For the best experience with frame-perfect playback, enable graphics acceleration in your browser and set all displays to 60fps in your computer's settings. If any display is over 60fps, frame drift may occur and the delayed video may be choppy. Only use above 60fps if your computer has a dedicated graphics card or powerful integrated graphics and can maintain a locked framerate.

-- Enabling/Disabling the Extension
Enable or disable the extension by pressing the bottom button in the GUI. The current on/off state is reflected here.

-- Changing Delay Modes Between Audio and Video
Video is delayed by default. Delay audio instead by clicking the yellow "Video" button at the top of the GUI. It will change to a red "Audio" button, and clicking it will return the delay mode back to video.

-- Changing the Delay Amount
Input the desired delay (in milliseconds) in the middle box of the GUI; no page refresh is required.

-- If Screen Tearing Occurs
NVIDIA GPU users:
- NVIDIA Control Panel -> Manage 3D Settings -> enable Vertical Sync in Global Settings or do so in Program Settings for your browser
- Set all displays to 60fps, as the delay mechanism is fundamentally different for videos at 60fps and above 60fps
- Follow potential fixes in the Intel section below
- Roll back drivers with NVCleanstall if all else fails. If on gaming drivers, try studio drivers instead. This would be understandably painful, but a non-tearing, synchronized video is worth the trouble. There are no other extensions that you can try instead that will give you the same quality delayed video as the original video itself.
- Send an email to [email protected] with a description of your issues and I will help resolve them

AMD GPU/iGPU users:
- AMD Adrenalin Software -> Gaming -> Display -> enable VRR

Intel GPU/iGPU users:
- Experiment with resolution settings, disabling hardware acceleration in the browser (will reduce performance but will confirm it's a GPU issue), and having multiple displays active (moving the cursor to the display not containing the video may help)

=== Known Bugs ===
Normal Instagram post videos are inconsistent due to undetermined video caching logic
